*607The respondent mother, Heather S.,1 has appealed from the trial court's judgment that Natalie S., the minor child of the respondent and Matthew B. (father), was neglected, and granting custody and guardianship of her to the father.2 The respondent sets forth two claims in her appeal. The first is that Connecticut law requires that the Department of Children and Families (department) continue efforts to reunify Natalie with her, and that the court erred in failing to order final specific steps or that the department make such *826additional reunification efforts. The second is that the court erred in failing to require the department to conduct further investigation into the father's fitness before granting custody and guardianship of Natalie to him and in permitting him to remove her to North Carolina. The petitioner, the Commissioner of Children and Families, disputes the respondent's claims. We affirm the judgment.3
In the neglect petition, the petitioner alleged, pursuant to General Statutes § 46b-120 (6), that Natalie was being denied proper care and attention, physically, educationally, emotionally, or morally, and was being permitted to live under conditions, circumstances or associations injurious to her well-being. Six days after *608the neglect hearing was concluded, the court issued its October 29, 2015 memorandum of decision. In that memorandum, the court set forth the following summary of the history of the case and extensive, detailed findings of fact that it found by a fair preponderance of the evidence.4 "On April 16, 2015, the [petitioner] moved the court for an order of temporary custody of [Natalie] born [in December 2013]. [The petitioner] contemporaneously filed a neglect petition alleging that Natalie was being denied proper care and attention and was living under conditions or circumstances injurious to her well-being. [The respondent] was duly served at her usual place of abode by a state marshal on April 17, 2015, with the motion for an [order of temporary custody], the neglect petition, summons, notice, and an order to appear for hearing. Respondent father was identified as John Doe whose whereabouts were unknown.
"[The respondent] appeared on April 17, 2015, for the preliminary [order of temporary custody] hearing. She was appointed counsel and advised. Thereafter, she waived the ten day hearing, agreed to have the [order of temporary custody] sustained and entered a pro forma plea [denying the allegations of neglect]. The case was continued to May 27, 2015, for proof of service and plea by John Doe.
"On May 27, 2015, John Doe appeared. He identified himself as Matthew B. [father]. [He] was appointed counsel, advised, and a pro forma plea was entered. Based on the results of paternity tests ordered by the court, Matthew B. was adjudicated the biological father of Natalie on July 14, 2015, and a judgment of paternity entered. On August 17, 2015, he moved the court to *609vacate the [order of temporary custody] and transfer guardianship and custody of Natalie to him. The motion was continued and consolidated with the neglect trial.
"The trial commenced on October 9, 2015. It continued on October 22 and thence to October 23, 2015, whereupon it concluded. [The respondent], the father, and their respective counsel were in attendance throughout the proceedings. [The petitioner] introduced numerous exhibits and testimony of two witnesses ... investigative social worker Luti Vinca and ... ongoing treatment social worker Rodney Moore. [The respondent] testified, introduced two exhibits into evidence, and called two witnesses ... a 'stay at home *827mom' and foster mother, and ... an expert in substance abuse counseling. The father introduced one exhibit and testified. He called no other witness[es]. The child's attorney submitted three exhibits and called no witness[es].
"The court has heard and carefully considered the testimony of all the witnesses; reviewed and carefully considered all of the exhibits; and has judicially noticed and thoroughly reviewed the verified petition. The credible and relevant evidence offered at trial, and a review of the judicially noticed court records, support the finding of the facts set forth below by a preponderance of the evidence presented."
The court proceeded to make the following factual findings: "Notice of this proceeding was provided in accordance with the Practice Book. Neither parent claims Native American tribal affiliation. The court is unaware of any proceeding pending in any other court regarding custody of the minor child. This court has jurisdiction.
"Due to reports of physical neglect, emotional neglect, substance abuse, mental health issues and criminal issues, [the department] has been involved *610with [the respondent] and Natalie since February 26, 2015. Three reports were received by [the department] expressing concern about [the respondent's] alleged substance abuse. On February 26, 2015, it was reported that Natalie was bitten by a dog, had two puncture wounds, was not dressed appropriately for the weather, [the respondent] kept alcohol in her purse, in her car, alcohol was smelled on her breath, and that [the respondent] had been seen driving with Natalie in her car. The allegations could not be substantiated.
"On March 7, 2015, [the respondent] was found unresponsive in her vehicle by her roommate in a Dunkin Donuts lot. [The respondent] admitted she'd taken more Ambien than prescribed. On April 16, 2015, [the respondent] was arrested at 2:51 a.m. with Natalie in the car. She was charged with driving under the influence of alcohol and with risk of injury to a minor.
"[The respondent's] criminal history includes arrests for possession of a controlled substance on September 4, 2009, felony possession of a controlled substance on May 20, 2010, disorderly conduct on August 30, 2014, and possession of a controlled substance in August, 2014. She has been diagnosed with mental health issues, alcohol abuse, and has been prescribed multiple different medications.
"She has struggled with alcohol abuse for many years. By her own admission she has had 'substance issues since May 2008' and 'a significant substance abuse issue since 2012.' [The respondent] relocated with Natalie from North Carolina to Connecticut in the fall of 2014. She, admittedly, came to [Connecticut] in 2014 because she had alcohol and other substance problems and needed help. While in North Carolina she [had] received mental health treatment for anxiety, depression and [attention deficit hyperactivity disorder ]. She and Natalie moved in with [the respondent's] father whom she described as bipolar and a drug addict.
*611"[The respondent] and the father met and began dating in Greensboro, [North Carolina] between 2011 and 2012. She refused having him listed on Natalie's birth certificate. She alleged he was very violent with her and kicked her down the stairs while she was pregnant with Natalie. She did not file a report or seek medical treatment concerning any purported abuse. Subsequently, she denied knowing the identity of Natalie's father. She reported she'd had sexual relations with multiple men while under the influence of *828alcohol when Natalie was conceived. [The respondent] has endeavored to have the father not be involved in Natalie's life and have no contact with her. The abuse allegations were vehemently denied by the father. [The respondent] offered no other evidence to substantiate the abuse allegations and thus they were unproven.
"[The department] made reasonable efforts prior to April 16, 2015, to prevent the removal of Natalie from her home. Natalie was placed and remains in a nonrelative foster home. She is well cared for, doing well and is medically up to date. No concerns have been noted. [The department] made reasonable efforts to reunify Natalie with both [the respondent] and the father. Natalie is completely dependent upon a consistent, stable, sober caregiver to meet her daily and emergency needs. [The department] has established that [the respondent] has failed in that regard.
"Specific steps to effectuate reunification of Natalie with [the respondent] were issued on April 23, 2015. [The department] made reasonable efforts to effectuate the reunification of Natalie with [the respondent]. [The department] offered [the respondent] casework services, visitation services, assessment services, substance abuse evaluations, screens, breathalyzers, and mental health assessment.
"[The respondent] was admitted into an intensive inpatient treatment program at Rushford on May 5, *6122015, for alcohol dependence. She completed the program on May 26, 2015. Her addiction counselor recommended she continue treatment in a relapse prevention or recovery program to keep fighting the disease. She failed to follow-up and relapsed during the weekend of July 25, 2015. She was then admitted on July 29, 2015, into a detox program followed by a twenty-eight day inpatient program. She completed the program and was admitted into an intensive inpatient treatment program. She completed the program at the McDonough House and was discharged on [August 29, 2015].
"Upon being discharged she was recommended for an intensive outpatient group.... Due to transportation issues presented by [the respondent], [she was afforded] the opportunity to attend a lower level relapse prevention group instead. She was to start the relapse prevention group ... [in] September 2015. She failed to show up for the [relapse prevention group] on September 8, 2015. She failed to show up again on September 23, 2015. On September 24, 2015, she was a no show for her individual appointment with her counselor. On October 14, 2015, she again failed to show up for the [relapse prevention group].
"[The respondent] did not have stable housing prior to Natalie's birth. Nor has she had stable housing since Natalie's birth. She lived with a series of friends and boyfriends while in [North Carolina]. Upon moving to [Connecticut] she and Natalie lived with her father for a few months, until he put her out. While living with her father she exercised poor judgment by leaving Natalie at various times in the sole and unsupervised care of her father whom she alleges sexually assaulted her as a child.
"After vacating her father's house in March 2015, she and Natalie moved in with a woman (Jessica) whom *613she'd met at [Alcoholics Anonymous] meetings. Thereafter, she moved in with Teague, a recovering alcoholic whom she'd also met at [Alcoholics Anonymous] meetings. Teague became her boyfriend. She lived with him temporarily until she entered the [intensive outpatient] program at Rushford followed by the [intensive outpatient] program at the McDonough House. Upon being discharged from the McDonough House she found residence at the House of *829Hope and Change in Danbury. It is a sober house for recovering women alcoholics. [The respondent] has been a resident there since August 29, 2015. There are no children at the sober house. All parties agree it is not an appropriate residence for Natalie. [The respondent] is required to reside there for three months. She may be discharged from the sober house on November 29, 2015. However, [the respondent] has no future housing prospects and she has no idea where she will reside after leaving the sober house.
"[The respondent] conceded during the trial that on April 16, 2015, Natalie was neglected in that she was subjected to conditions injurious to her well-being. [The respondent] admitted during the trial that she is an alcoholic and relapsed with alcohol and Ambien. [The respondent] further conceded during the trial that substance abuse has impacted her ability to care for Natalie.
"Notwithstanding the sporadic and inconsistent progress [the respondent] has made, she has not yet progressed enough with her substance abuse, mental health and housing stability to have Natalie returned to her care at this time. She has not yet achieved the degree of rehabilitation necessary. Her substance abuse and mental health continue to be major concerns after her relapse the weekend of July 25, 2015. She is currently in a dating relationship with a man whom she met at an [Alcoholics Anonymous] meeting and whom she relies upon as a source of support. She has failed to demonstrate that she is now or [could] in the reasonably *614foreseeable future be a consistent, stable, sober caregiver to Natalie, able to meet her daily and emergency needs.
"The father was noncustodial at the time of Natalie's removal by [the department]. [The respondent] purposefully concealed and kept her and Natalie's whereabouts from being made known to him. At a considered removal meeting with [the department] [on] or about April 28, 2015, [the respondent] identified the father for the first time as the putative father of Natalie. After being noticed, the father appeared in [Connecticut] on or prior to May 27, 2015. Prior to May 2015, he had not seen Natalie since she was a few months old. His absence in her life is due solely to [the respondent's] efforts to keep Natalie's whereabouts unknown to him. She knew he was Natalie's father. He was prevented from coming forward earlier and providing support for Natalie and presenting himself as a resource for her. He approached [the department] contending he was Natalie's biological father. He provided [the department] with a copy of the results of a paternity test done on July 1, 2013 in [North Carolina]. He has been fully cooperative with [the department] in every respect since then. No specific steps were issued for the father. [The department] did not recommend any services for him. [The department] could not identify any areas for services which he [needs]. He has been very responsive and fully cooperative with all requests made of him by [the department].
"The father recognizes the need and desires to keep [the respondent] involved in Natalie's life. He [is] willing to allow her to enjoy liberal and flexible visitation and other contact with Natalie. He has never been married and is not in a dating relationship. He continues to reside in Greensboro, [North Carolina] with his mother and father in their home. [S]ocial worker Rodney Moore flew to Greensboro, [North Carolina] on October 15, *6152015, to interview [the father's] parents and inspect their home. His parents are his support system. They are committed to helping him care for Natalie. A records check by [the department] into the background of *830the paternal grandparents revealed no concerns. Their home is a big single-family house situated on a large property. It is 'child proofed,' there is a bedroom fully furnished with a bed already set up for Natalie's sole use, lots of toys, clothing, and pictures. It is a safe, nurturing, and appropriate residence for Natalie.
"The father served in the U.S. Army as a parachute rigger in the 82nd Airborne Division and was honorably discharged. A background check by [the department] disclosed no criminal or domestic violence history for the father. Substance abuse test results for the father were all negative. [The respondent's] unsubstantiated allegation that he abused illegal and prescription drugs is given no weight by this court. He previously worked as a commercial scuba diver and with the Boy Scouts of America. He currently works with youth groups within his church. He is employed full-time as a horse farm manager. He earns about $20,000 a year. He has Blue Cross/Blue Shield health insurance. It is available for Natalie should she be in his care. Since May 2015, he has travelled regularly on weekends from [North Carolina] to [Connecticut] to visit Natalie. He has driven to [Connecticut] at his expense. He has travelled to [Connecticut] two times by airplane. He [has] also visited with her each time he has had to appear in [Connecticut] for court."
Accordingly, the court adjudicated Natalie neglected, vacated the order of temporary custody, and granted custody and guardianship to the father. This appeal followed.
*616I
The parties agree that as to the first issue, namely, whether the department had a continuing duty to provide reunification services to the respondent, the question is one of statutory construction and the standard of review is therefore plenary. See Marchesi v. Board of Selectmen, 309 Conn. 608, 614, 72 A.3d 394 (2013).
The respondent argues that the department has a continuing statutory obligation to make reasonable efforts to reunify the child with her, even after the adjudication of neglect and the awarding of custody and guardianship to the father, who was a biological parent like the mother.5 In support of her claim, she relies on General Statutes § 46b-129 (j)(3), which provides that if custody is awarded to an individual other than a parent or former guardian, the court shall order specific steps that the parent must take to facilitate the return of the child.6 In this case, *831however, her reliance *617is misplaced because the court vested custody and guardianship in the father, whose underlying parental rights are equal to those of the respondent,7 and not in the petitioner or any other related or unrelated third party.
The respondent further argues that her right to continuing services from the department not only is predicated on the specific steps language in § 46b-129 (j)(3), *618but that it also derives from General Statutes § 17a-111b (a). What is before this court, however, is an appeal from a neglect adjudication and disposition pursuant to General Statutes § 46b-120 et seq., including § 46b-129.8 It is not an appeal from a termination of parental rights adjudication and disposition pursuant to *832General Statutes § 17a-111a9 et seq., including § 17a-111b (a).10 The result of the trial court's disposition is that although the father currently has custody and guardianship of Natalie, and family integrity is preserved to the maximum extent possible in the specific circumstances of *619this case, the respondent has not lost her right to attempt to modify the court's order to obtain a transfer of custody and guardianship to her by persuading a court that doing so is in the best interest of Natalie. See Fish v. Fish, 285 Conn. 24, 84, 939 A.2d 1040 (2008) ; Knock v. Knock, 224 Conn. 776, 785, 621 A.2d 267 (1993) ; Hibbard v. Hibbard, 139 Conn.App. 10, 20-22, 55 A.3d 301 (2012) ; Malave v. Ortiz, 114 Conn.App. 414, 416, 970 A.2d 743 (2009) ; see also General Statutes § 46b-56.
If, after a neglect adjudication, a child is committed to the care, custody, and guardianship of the commissioner pursuant to § 46b-129 (j)(2)(A),11 the department does have a continuing statutory duty to provide reunification services. See General Statutes § 17a-111b (a). This duty, however, does not exist when the dispositional award of custody and guardianship is to a parent.12 In In re Pedro J.C., 154 Conn.App. 517, 538-39, 105 A.3d 943 (2014), this court stated: "In this case, the commissioner did not recommend or advocate for any particular custodial option. The court in this case chose the second option [a relative pursuant to § 46b-129 (j)(2)(B) ] as being in the ... best interest [of the petitioner, Pedro J.C., a seventeen year old child] and transferred custody and guardianship [of him] to [a cousin]. Such a disposition deprived the court of continuing jurisdiction to promote the reunification with the respondent [mother] it subsequently found viable. A *620transfer of guardianship to someone other than a parent results in the cessation of any requirement that reunification efforts be made, and we fail to see how *833reunification, when contemplated in state child protection proceedings, remains viable when no state agency is authorized to make reasonable efforts toward reunification.... A decision to remove a child from parental custody in a neglect proceeding is not always subject to periodic judicial review to assess the well-being of the child and to approve a permanency plan for the child's care and custody, whether that be reunification with the parent, adoption, a transfer of guardianship, or long-term foster care within a year of removal. The periodic judicial review described in § 46b-129 applies only if the child is committed to the custody of the department. The legislature ... did not contemplate mandatory, periodic judicial review of cases in which custody, rather than ordered as a commitment of the child to [the department, has] been vested by the court in an appropriate third party.... Fish v. Fish, [supra, 285 Conn. at 83, 939 A.2d 1040 ]. Once the court decided to transfer custody and guardianship to [the cousin], the only way reunification [with the respondent] would be restored to viability would be if the respondent opposed that dispositional status and either appealed or subsequently filed a petition to reinstate her guardianship of the child.13 General Statutes § 46b-129 (n)....
"Accordingly, we conclude that the court's failure to find that reunification with the respondent was not *621viable due to neglect under state law was erroneous as a matter of law because it was internally inconsistent with the court's dispositional order on the neglect petition, which transferred the custody and guardianship of the petitioner to [the cousin]."(Footnotes altered; internal quotation marks omitted.) In re Pedro J.C., supra, 154 Conn.App. at 538-39, 105 A.3d 943.
The principles set forth in In re Pedro J.C. are applicable both in the context of a transfer of custody and guardianship from one parent to the other, and in the context of a transfer of custody and guardianship from the petitioner to a biological parent as a dispositional result of a neglect proceeding. The court's disposition in the present case awarding custody and guardianship to the father deprived it of continuing jurisdiction over the respondent's possible future reunification with Natalie and thus required the cessation of such reunification efforts.
II
The respondent's second claim is that the court erred in failing to require further investigation of the father's fitness to parent before granting custody and guardianship to him and permitting him to remove Natalie to North Carolina, and that such further investigation was required by the department's duty to make reasonable efforts toward reunification of the respondent with Natalie.14 The respondent argues *834that there was both statutory authorization and a factual basis for such further investigation of the father. *622We review the court's findings of fact under the clear error standard. "A finding of fact is clearly erroneous when there is no evidence in the record to support it ... or when although there is evidence to support it, the reviewing court on the entire evidence is left with the definite and firm conviction that a mistake has been committed.... Because it is the trial court's function to weigh the evidence and determine credibility, we give great deference to its findings.... In reviewing factual findings, [w]e do not examine the record to determine whether the [court] could have reached a conclusion other than the one reached.... Instead, we make every reasonable presumption ... in favor of the trial court's ruling."(Internal quotation marks omitted.) Bender v. Bender, 292 Conn. 696, 728-29, 975 A.2d 636 (2009). We give plenary review to the respondent's claims of statutory construction and application in support of her second claim. See Marchesi v. Board of Selectmen, supra, 309 Conn. at 614, 72 A.3d 394.
The respondent argues that the petitioner's alleged "failure to conduct an adequate investigation implicates the trial court's conclusions concerning [the department's] obligation to make reasonable efforts before removing a child from the home." The respondent also asserts that "[t]here is no dispute that, before removing *623a child from her custodial parent, [the department] must make reasonable efforts to avoid the removal,"15 and "[t]his obligation applies in the context of a neglect petition as well as a petition for termination, and includes the obligation, in the context of this case in particular, to perform a thorough investigation before removing a child and placing her out of state." It is not disputed, however, that the department provided substantial services to the respondent and Natalie for several months after the filing of the neglect petition in April, 2015, through late October, 2015. To the extent, however, that the "reasonable efforts" that the respondent asserts are required include the department's performance of such a "thorough investigation," she has not cited any relevant authority for this proposition.16 *624She does cite in support of her claim *835General Statutes § 17a-112, which describes standards and requirements for the termination of parental rights, and In re Jason M., 140 Conn.App. 708, 720-21, 59 A.3d 902, cert. denied, 308 Conn. 931, 64 A.3d 330, cert. denied sub nom. Charline P. v. Connecticut Dep. of Children & Families, ---U.S. ----, 134 S.Ct. 701, 187 L.Ed.2d 564 (2013), an appeal from a termination of parental rights. The respondent, however, acknowledges that we held in In re Pedro J.C., a neglect proceeding, that the department has no continuing obligation to make further reasonable efforts17 toward a respondent's reunification with a child if custody and guardianship of such child is not committed by the court to the petitioner. To the extent the respondent claims that a "thorough investigation" of the father was required to be made in this case by the department as part of its "reasonable efforts" to reunify the respondent with Natalie, we reject that claim.
The respondent also argues that there was substantial factual evidence calling the father's fitness into question. She, however, in her brief "does not contend that this evidence required that the trial court find the father unfit, or find even that the alleged events had occurred. The significance of this evidence was only in that it should have triggered in the petitioner an obligation (and from the trial court, an order) to do a thorough investigation into the father's fitness before allowing Natalie to be removed from [the respondent] and moved to North Carolina with him." The respondent then set forth her unsubstantiated and unproven allegations about the father that were not found as fact by the *625court, and she made unsupported allegations about the department's activities or lack thereof relating to its investigation of the father's fitness to be a custodial parent and guardian of Natalie. The respondent does not assert that any specific fact found by the court is clearly erroneous. She did not offer any specific evidence in the neglect hearing to support her claims about the department's failure to perform any required additional investigation of the father.
The respondent additionally argues that the court could have entered orders, *836pursuant to its authority recognized in In re Emoni W., 305 Conn. 723, 741, 48 A.3d 1 (2012), placing conditions on the father's exercise of custody. The court's findings of fact set forth previously in this opinion do not provide any support for her allegations about the father's lack of fitness, and the court did not credit them. The court instead found that the father did not have custody of Natalie at the time of her removal by the department. He had not come forward earlier to provide support for Natalie or to present himself as a resource for her because the respondent had purposefully kept Natalie's whereabouts from being known to him. Since receiving notice, the father appeared in Connecticut and provided evidence of his paternity. He has been fully cooperative with the department in every respect since then. No specific steps were ordered for him by the court and the department could not identify any areas for which he had need for services.
The court further found: "The father recognizes the need and desires to keep [the respondent] involved in Natalie's life. He [is] willing to allow her to enjoy liberal and flexible visitation and other contact with Natalie. He has never been married and is not in a dating relationship. He continues to reside in Greensboro, [North Carolina] with his mother and father in their home. [S]ocial worker Rodney Moore flew to Greensboro, *626[North Carolina] on October 15, 2015, to interview [the father's] parents and inspect their home. His parents are his support system. They are committed to helping him care for Natalie. A records check by [the department] into the background of the paternal grandparents there is a bedroom fully furnished with a bed already set up for Natalie's sole use, lots of toys, clothing, and pictures. It is a safe, nurturing, and appropriate residence for Natalie."
On the basis of these findings, which the respondent does not claim were clearly erroneous, we cannot conclude that the trial court erred in declining to enter orders placing conditions on Natalie's placement with the father pursuant to its authority recognized in In re Emoni W, supra, 305 Conn. at 736-37, 741, 48 A.3d 1. Moreover, the respondent has failed to establish on appeal that, after the court's adjudication of neglect and dispositional award of custody and guardianship to the father, instead of commitment of the child to the care, custody and guardianship of the petitioner, the department has any statutory duty or authority to continue its activities with or for the respondent, the father or Natalie. See In re Pedro J. C., supra, 154 Conn.App. at 538-39, 105 A.3d 943.
The judgment is affirmed.
In this opinion the other judges concurred.
