On 5 September 1958 the defendants Ricard, Connor, and McLean, Trustee, requested the Clerk of the Superior Court of Wilson County to place this action on the pre-trial docket. On 7 January 1959, Judge Frizzelle ordered that -thi-s ca-se be set for trial per*488emptorily as the first case for trial >at the June 1959 Civil Term of the Superior Court of Wilson County.
At .the June 1959 Term, Judge Frizzelle entered what is designated as a “Pre-Trial Order,” which is in substance: Plaintiffs moved for a continuance. Judge Frizzelle denied the motion, and plaintiffs excepted. Defendant Ricard moved that her pleas in bar be heard and determined prior to the trial on the merits. Judge Frizzelle, in Ms discretion, granted defendant Rieard’s motion, and set the hearing of the pleas in 'bar for 22 June 1959. Plaintiffs excepted to the order.
Judge Frizzelle, without a jury, heard the pleas in bar of defendant Rioard. Defendant Ricard offered in evidence her answer containing her pleas in bar of estoppel by judgment and res jvdicata. At this point .plaintiffs’ counsel read to Judge Frizzelle their reply to defendant Rioard’s pleas in bar and counterclaim. Then defendant Rioard in support of her pleas in bar offered in evidence the following: the pleadings in the first action on the second appeal to tMs Court, with the two deeds attached as exhibits to the amended complaint; the judgment of Judge George M. Fountain, entered at the September 1956 Civil Term, nonsuiting plaintiffs’ first action; the appeal entries on the second appeal; the .summons in the first action with the Sheriff’s return; the proceedings making additional parties in the first action; the opinion of this Court on the second appeal, which is reported in 245 N.C. 687, 97 S.E. 2d 105; a transcript of the record in the trial of the first action, which resulted in the second appeal to this Court, containing the testimony of Mrs. Annie 'Parker Phillips, of Mrs. Nana Louvi-nia Parker, of George A. Barfbot, of Mrs. Bessie Lamm, of R. H. Jackson, and B. F. Yarnell, all witnesses for plaintiffs, in the form of questions and answers; and also containing copies of the deed from Nana Louvinia Parker and others to R. A. Stamper tand wife, of the .deed from R. A. Stamper and wife to Grover T. Lamm, of the deed from R. A. .Stamper and wife to defendant Ricard, who was then Eunice Williamson Decker, and stipulations and comments of counsel. Defendant Ricard also introduced some immaterial pleadings, e. g., her answer to the original complaint, when the first action was tried twice in the Superior Court resulting in two appeals to this Court on an amended .complaint, and the original oomplaint is not in either of the records of those two appeals.
Plaintiffs offered in evidence before Judge Frizzelle the following: The testimony .of W. A. Lucas, in the form of questions and answers, given at a former trial of the first action before Judge Carr in November 1954. Incorporated in W. A. Lucas’ testimony is a copy of the Will of Grover T. Lamm. Plaintiffs also offered in evidence a eopji of a will and copies of deeds in reference to the land which is the *489subject matter of this present action. Plaintiffs also offered in evidence a transcript of the testimony of defendant Ricard given in the first trial of the hearing before Judge Oarr, largely in the form of questions and answers. Judge Frizzel-le excluded this testimony as irrelevant, but permitted counsel to read it into the record.
Judge Frizzelle entered a judgment in substance: Plaintiffs’ complaint in the ease fixes their alleged cause of action as one in the nature of ejectment, and fixes their claim of title to the land described in their complaint -a-s -being derived from R. A. Stamper and wife. That a prior action upon the same alleged cause of action, and seeking the same relief, was instituted in -the Superior Court of Wilson County by summons issued 24 December 1952. The parties plaintiff in the prior action were the same as the parties plaintiff in this action. The -parties defendant in the -prior action were the same as the -parties defendant in this -action, with the exception of H. G. Con-nor and Charles B. McLean, Trustee, 'both of w-hom aver they -have acquired interests in the land, the subject matter of this action, from the defendant Ricard. Plaintiffs’ first action was tried at the September 1956 Civil Term of the Superior Court of Wilson County. At said trial plaintiffs sought to establish their alleged cause of action by showing that they and the defendant Ricard claimed title to the locus in. quo from a common source, to wit, R. A. Stamper -and wife. At said trial plaintiffs introduced evidence to support their alleged title from the common source, and introduced further evidence to support defendant Ricard’s claim of title from the common source. Plaintiffs offered nothing by way of attack upon the title of defendant Ricard. After plaintiffs had closed their evidence, defendant Ricard moved for judgment of nonsuit. Thus, squarely presented, was the question for legal determination: Which claim of title from the common source was the better? The trial judge entered judgment of non-suit, and dismissed plaintiffs’ -action. Upon appeal to the Supreme Court, the judgment w-a-s affirmed, and the Supreme Court held that plaintiffs proved themselves out of court by showing a superior title in defendant Ricard from the common source. Plaintiffs’ .claim to the locus in quo rests solely upon it being determined in this action that they hold -the better title than -defendant Ricard from R. A. Stamper -and wife. That question wr-as judicially determined adverse -to plaintiffs in a prior action. Thus, a fact essential- to plaintiffs’ action, that defendant Ricardi holds the better title from R. A. Stamper and wife, has been directly tried and decided. This essential fact cannot be contested again between the same parties, or their privies, in the same or any other court. Plaintiffs a-re estopped to deny the aforestated particular fact, which is essential to the cause of action alleged in *490their complaint. At the former trial the way was open to plaintiffs to ■attack defendant Ricard’s claim of title, that they had offered in evidence, upon ^any and all existing grounds, both legal and equitable. It was incumbent upon them to bring forward, and assent their whole case. Plaintiffs have had their day in court, and have had the opportunity to disprove defendant Ricard’s claim of title that they, the plaintiffs, offered in evidence. They have waived their right to assert and prove their attack alleged in the complaint in this case on defendant Ricard’s claim of title. Whereupon, Judge Frizzelle adjudged and decreed that the pleas in bar of the defendants Ricard, Connor and Charles B. McLean, Trustee, be allowed, and dismissed plaintiffs’ action. Plaintiffs are estopped to relitigate the question as to whether they or defendant Ricard hold the better title to the land described in the-complaint from R. A. Stamper and wife, a common source; and the judicial determination of the former action, which was affirmed in the' Supreme Court, operates as an estoppel, -and as res judicata against plaintiffs to maintain this action.
Plaintiffs assign as error the refusal of the court to grant them -a continuance to a subsequent term. The granting or denying of a motion -for a continuance rests in the sound discretion of the presiding judge, and his decision will not be disturbed on appeal, except for abuse of discretion. No abuse -of discretion has been shown. This assignment of error is overruled. Furniture Co. v. Baron, 243 N.C. 502, 91 S.E. 2d 236.
Plaintiffs assign as error the court’s hearing defendant Ricard’s pleas in bar prior to the trial of the action on its merits. The pleas in bar of defendants Ricard, Connor, and McLean, Trustee, deny plaintiffs’ right to maintain the action, and if established, will destroy their action. “Ordinarily, it is for the trial judge, in the exercise of his discretion, to determine whether in the circumstances of a particular case a plea in bar is to be disposed of prior to trial on the merits of plaintiff’s alleged cause of action.” Gillikin v. Gillikin, 248 N.C. 710, 104 S.E. 2d 861. This assignment of -error is overruled.
Plaintiffs contend in their brief that the pleas in bar were heard, and determined at a pre-trial conference. It is manifest from a study of the record that the pleas in bar were -not heard, and determined 'at a pre-trial conference, but were heardi, and determined at a regular term of -court, in open court, according to the practice of the Superior Courts of the State.
Plaintiffs in their brief contend that the evidence offered in defense of the pleas in bar was admitted without proof of authenticity, "and that counsel for .said defendant proceeded to offer such evidence without a stipulation as to its authenticity.” On page 63 *491of the record, we find this: “The authenticity of the records offered by both parties admitted by both' parties. J. P. F., Judge.” There seems to be no merit to this contention.
The general rule is well settled that the doctrine of res judicata, whereby a judgment bars a subsequent action on the same cause of action, and renders the judgment conclusive on the issues adjudicated, applies only to the parties to the action in which the judgment was renderedi, ’and the privies of such parties. Bennett v. Holmes, 18 N.C. 486; Meacham v. Larus & Bros. Co., 212 N.C. 646, 194 S.E. 99; Rabil v. Farris, 213 N.C. 414, 196 S.E. 321; Corporation Commission v. Bank, 220 N.C. 48, 16 S.E. 2d 473; Cannon v. Cannon, 223 N.C. 664, 28 S.E. 2d 240; 30A Am. Jur., Judgments, Sec. 396; 50 C.J.S., Judgments, Sec. 762.
In U. S. v. California Bridge & C. Co., 245 U.S. 337, 62 L. Ed. 332, the Gourt said: “The doctrine of estoppel by judgment, or res judicata, as a practical matter, proceeds .upon the principle that one person shall not a second time litigate, with the same person or with another so identified in interest with such person that he represents the same legal right, precisely the same question, particular controversy, or issue which has been necessarily tried and finally determined, upon its merits, by a court of competent jurisdiction, in a judgment in personam in a former suit.”
A former judgment of nonsuit is res judicata as to a second action, only when it is made to appear that the former adjudication has been on ’the merits of the action, and it .appears to the trial court, ’and is found by such court as a fact, that the second action is between the same parties in the same capacity or quality, and their privies, and is based upon substantially identical 'allegation and substantially identical evidence, 'and that the merits of the second action are identically the same. Kelly v. Kelly, 241 N.C. 146, 84 S.E. 2d 809; Craver v. Spaugh, 227 N.C. 129, 41 S.E. 2d 82; Hampton v. Spinning Co., 198 N.C. 235, 151 S.E. 266; 17 Am. Jur., Dismissal, Etc., p. 162; 27 C.J.S., Dismissal and Nonsuit, p. 404; 30A Am. Jur., Judgments, Section 398.
“A judgment on the merits is said to be one which is based on legal rights as distinguished from mere matters of practice, procedure, jurisdiction, or form, or is a judgment that determines, on an issue either of law or fact, which party is right.” 30A Am. Jur., Judgments, Sec. 348.
The pleas in bar “cannot be determined from the pleadings alone.” Craver v. Spaugh, supra, and cases there cited.
This Court said in Kelly v. Kelly, supra: “Ordinarily, if the evidence on which the plea of res judicata is sustained tends to show *492the facts to be as found by the trial court, its findings will not be reviewed by this Court.”
The parties plaintiff in the former action and in the instant action are the same, with this exception: In the .instant case a new plaintiff 'appears, Jack Thomas Hayes, an infant son of Virginia Lamm Hayes and husband, J. F. Hayes, 'and a brother of the infant plaintiff Tem-pie Ann Hayes. In the former’ action, Tempie Ann Hayes appeared! by her next friend, J. W. Harrison: in the present case both infants appear by their next friend, J. W. Harrison. It would seem that Jack Thomas Hayes was bom subsequent to our decision on the second appeal of the first action. The Will of Grover T. Lamm devises certain interests in his realty to his daughter, Virginia Lamm Hayes, for her life, after the termination of a life estate devised to his wife, and •at Virginia Lamm Hayes’ death, to her ■children. His will refers to no grandchildren by name, except Betty Frances Lamm, daughter of his late son, Oliver Lamm. It appears from the record that Jack Thomas Hayes is so identified in interest with Tempie Ann Hayes that he was in privity with her who was a party to the prior adjudication, .and represented the same legal right. 30A Am. Jur., Judgments, p. 451. “ ‘Privity’ is the mutual or successive relationship to the same right of property, or such an identification in interest of one person with another as to represent the same legal right.” 72 C.J.S., Privity; Privies; Privy, pp. 954-5.
The parties defendant in the former action and in the instant case are identical, with this exception: In the instant case two new defendants appear, H. G. Connor and Charles B. McLean, Trustee. The decision on the second appeal of the first action was filed 27 March 1957. On 1 May 1957, defendant Rioard 'conveyed to H. G. Connor by d/eed duly recorded a portion of the land that is the subject matter of the former action and the present action. On the same date defendant Ricard executed and delivered to Charles B. McLean, Trustee, ia deed of trust duly recorded, securing an indebtedness of $2,000.00 •due H. G. Connor, and conveying to the Trustee all of this same land, except the portion conveyed to H. G. Connor. H. G. Connor and Charles B. McLean, Trustee, are privies in estate with defendant Rioard, due to their relationship of grantor and grantees. 72 C.J.S., Privity; Privies; Privy, Privity in Estate, pp. 960-961.
Judge Frizzelle found that the parties plaintiff in the prior action were the same as the parties plaintiff in the instant action. By inadvertence he did not refer to the infant Jack Thomas Hayes, who is in privity with his infant sister, Tempie Ann Hayes. Judge Frizzelle’s findings show the privity of estate between defendant Rioard and defendants Connor and McLean, Trustee. However, considering Judge *493Frizzelle’s judgment in its entirety, we are of opinion that bis findings of fact are sufficient that there is an identity of parties in the first action and the present action, within the doctrine of res judicata, and that the evidence supports such findings.
The pleadings ¡on the two appeals to this Court of the former action are identical. The complaint in the instant case is identical with the amended complaint on the two appeals to this Court of the former action — only the amended complaint ¡appears in the records on 'the two former ¡appeals —, with these exceptions: One. An allegation -in the instant action that Jack Thomas Hayes is ¡an infant son of Virginia- Lamm Hayes and husband, J. F. Hayes, and appears herein by his next friend. Two. The addition in the present ¡complaint of a new ¡sub-paragraph to paragraph XII of the amended complaint in the former action. Paragraph XII begins: “Said claim of defendant Ricard is valid neither in law nor in fact for that”: The new sub-paragraph reads: “E. In the year 1946, ©aid Grover T. Lamm placed defendant Ricard and her family in possession of said lands ¡as his tenants, and continuously thereafter until his death and ¡at the time thereof they were in possession ¡of said lands as such tenants, and since his death said defendant has been wrongfully holding over and withholding the possession of said lands from the plaintiffs.” Three. The ¡amended complaint in the former action requests, inter alia, the appointment of a receiver to take possession of the subject matter of the action: this is omitted in the complaint in the present action. Four. The amended complaint in ¡the former action alleges defendant Ricard is a resident of North Carolina: the complaint in the present case alleges she is ¡a resident of South Dakota.
After plaintiffs filed their complaint in the -instant case, they had H. G. Connor -and Charles B. McLean, Trustee, made parties defendant, and filed an -amendment to their complaint to ¡this effect: That defendant Ricard’© deed to Connor and deed of trust to McLean, Trustee, are void, and conveyed nothing to them, because plaintiffs filed -a lis pendens ¡as to the tract of land on 24 December 1952, when they instituted their first ¡action, that -Connor was of counsel for -defendant Ricard in the first action, -and that Connor 'and McLean, Trustee, knew defendant Ricard did not ¡own the land she purported to convey to Connor and McLean, Trustee.
In the former action plaintiffs filed a reply to defendant Rioard’s -supplemental ¡answer, in which in paragraph A they allege: “Defendant Ricard i-s estopped to deny the fee simple ¡title of Grover T. Lamm and the title of plaintiffs to -said land for that”: -and then follows an -allegation of practically the identical words contained in *494Paragraph XII, sub-paragraph E, of their complaint in the instant case, above set forth.
This Court said in King v. Neese, 233 N.C. 132, 63 S.E. 2d 123: “Where a second action or proceeding is between the same parties as a first action or proceeding, the judgment in the former -action or proceeding is conclusive in the latter not only as to all matters .actually litigated and determined, but also as to all matters which could properly have been litigated and determined in the former -action or proceeding.” To the same effect see 30A Am. Jur., Judgments, Sec. 372, where numerous cases are cited from many jurisdictions.
This Court said in Bruton v. Light Co., 217 N.C. 1, 6 S.E. 2d 822: “A judgment rendered in an action -estops the parties and their privies as to all issuable matters -contained in the pleadings, including all material and relevant matfei-s within the scope of the pleadings, which the parties, in the exercise of reasonable diligence, could and should have brought forward. Citing cases. The whole tendency of our decisions iis to require a plaintiff to try his whole cause of action and his whole case at one time. He can neither split up his claim nor divide the grounds of recovery.”
For an analysis of the pleadings in the former action see 244 N.C. 313, 93 S.E. 2d 540. That decision also contains -a summary of the evidence -in that trial. See also 245 N.C. 687, 97 S.E. 2d 105, for the second appeal of the former -action.
A judgment of nonsuit on the merits and after a full hearing, stands upon a different basis from those judgments of nonsuit upon other causes and upon other grounds, -where -a plaintiff can bring a new action under G.S. 1-25, and “mend his licks,” if he can. Hampton v. Spinning Co., supra.
The judgment of involuntary nonsuit entered in the former action, and affirmed by this Court, 245 N.C. 687, 97 S.E. 2d 105, was an adjudication upon the merits of the action, for that plaintiffs’ evidence showed affirmatively that defendant Ricard had a better title to the land from a common source, and that they 'are not entitled to recover, which was her defense.
Plaintiffs contend that in the -instant case other issues are presented, which were not presented when the former action was tried and nonsuited, to wit: Whether defendant Ricard w-as a tenant of Grover T. Lamm; whether the deed to defendant Ricard was without consideration; whether the deed to defendant Ricard was a -deed of gift -and not registered within two years from the date of delivery, etc. All these matters were -alleged by plaintiffs in their pleadings in the former -action, -and might -have been litigated in that action. If plaintiffs did not see fit to present evidence on their whole case, -as alleged *495in their pleadings, when the fonner action was tried andi nonsuited, that was their choosing, and they must abide the consequences. King v. Neese, supra; Bruton v. Light Co., supra; Gibbs v. Higgins, 215 N.C. 201, 1 S.E. 2d 554; Cropsey v. Markham, 171 N.C. 43, 87 S.E. 950; Coltrane v. Laughlin, 157 N.C. 282, 72 S.E. 961.
In studying the evidence we have considered plaintiffs’ evidence excluded by Judge Frizzelle, as if he had admitted it. The evidence introduced/ in the hearing before Judge Frizzelle supports his findings of fact, and such findings support his conclusions, and his judgment based thereon. The merits of the two actions are the same.
The conveyances by defendant Ricard to Connor and McLean, Trastee, do not prevent the application here of the principles of res judicata and estoppel by judgment, and the sustaining of such pleas in bar destroys plaintiffs’ action.
Upon the record before us, the pleas in bar were properly heard and! determined by Judge Frizzelle without a jury, for the reason that the proof admits of only one conclusion. 50 C.J.S., Judgments, Sections 845-6.
What was said in Ingle v. Cassady, 211 N.C. 287, 189 S.E. 776, with a change of names, is in point here: “This is the ‘same candle blown out in the original action,’ Hayes v. Ricard, 245 N.C. 687, 97 S.E. 2d 340, ‘and lighted again in the present action.’ ”
All plaintiffs’ assignments of error are overruled. The judgment below is
