. Katrina Letress Griffis (“plaintiff’) appeals from orders entered denying her motion to proceed in forma pauperis and granting Patricia Joyce Lazarovich (“Lazarovich”), John Edward Lazarovich, and Cassandra Michelle Leak’s (“Leak”) (collectively, “defendants”) motions for costs. We affirm.
I. Background
This is the second appeal arising from plaintiff’s action for personal injuries sustained as the result of an automobile accident involving a vehicle driven by Lazarovich and a vehicle driven by Leak, in which plaintiff was a passenger. See Griffis v. Lazarovich, 161 N.C. App. 434, 588 S.E.2d 918 (2003) (“Griffis E). In Griffis I, we held there was no error in the jury’s verdict, the 26 July 2002 judgment entered thereon of no negligence on the part of defendants, and the 29 August 2002 trial court’s order denying plaintiff’s motions for judgment notwithstanding the verdict and a new trial. Id.
On 14 August 2002, Leak filed a motion for costs. Thereafter, on 16 August 2002, plaintiff filed a motion to proceed in forma pauperis. On 19 August 2002, Lazarovich and her husband John *331Edward Lazarovich (collectively, “the Lazaroviches”) also filed a motion for costs. Subsequent to this motion, on 4 September 2002 plaintiff filed an affidavit in support of her motion to proceed in forma pauperis. By orders dated 13 March 2003, 24 March 2003, and 28 April 2003, the trial court granted defendants’ motions for costs and denied plaintiffs motion to proceed in forma pauperis. Plaintiff appeals.
II. Issues
Plaintiff contends the trial court erred in: (1) denying her motion to proceed in forma pauperis) and (2) granting defendants’ motions for costs.
III. Motion to Proceed In Form,a Pauneris
[1] “The right to sue as a pauper is a favor granted by the court and remains throughout the trial in the power and discretion of the court.” Whedbee v. Ruffin, 191 N.C. 257, 259, 131 S.E. 653, 654 (1926) (citing Dale v. Presnell, 119 N.C. 489, 26 S.E. 27 (1896)). To support an abuse of discretion, plaintiff must show that the trial court’s ruling was “manifestly unsupported by reason,” or “so arbitrary that it could not have been the result of a reasoned decision.” Briley v. Farabow, 348 N.C. 537, 547, 501 S.E.2d 649, 656 (1998).
Plaintiff contends the trial court abused its discretion in denying her motion to proceed informa pauperis under both N.C. Gen. Stat. § 1-288 and N.C. Gen. Stat. § 1-110.
A. N.C. Gen. Stat,. § 1-288
Under N.C. Gen. Stat. § 1-288 (2003), a person seeking to proceed in forma pauperis on appeal is required to file an affidavit indicating that he or she is unable by reason of poverty to give the security required by law within thirty days after the entry of the judgment or order. The judgment was entered on 26 July 2002, and plaintiff did not file her affidavit of indigency until 4 September 2002. Plaintiff’s affidavit was not filed within thirty days of the entry of judgment. The trial court did not abuse its discretion in denying plaintiff’s motion to proceed in forma pauperis on appeal pursuant to N.C. Gen. Stat. § 1-288.
B. N.C. Gen. Stat. § I-110
N.C. Gen. Stat. § 1-110 (2003) is entitled, “Suit as an indigent” and states,
*332(a) Subject to the provisions of subsection (b) of this section with respect to prison inmates, any superior or district court judge or clerk of the superior court may authorize a person to sue as an indigent in their respective courts when the person makes affidavit that he or she is unable to advance the required court costs. The clerk of superior court shall authorize a person to sue as an indigent if the person makes the required affidavit and meets one or more of the following criteria:
(1) Receives food stamps.
(2) Receives Work First Family Assistance.
(3) Receives Supplemental Security Income (SSI)
This statute is found in Article 9 of the civil procedure chapter and applies to “prosecution bonds.”
Here, the trial court made findings of fact, to which plaintiff does not assign as error on appeal. Findings of fact not challenged by an exception or assignment of error are binding on appeal. Tinkham v. Hall, 47 N.C. App. 652-53, 267 S.E.2d 588, 590 (1980). The trial court’s findings show that plaintiff is a single mother of one child, lives in subsidized housing, and has a present monthly income of $960.00. Her expenses total $716.60, and her only alleged debt are medical bills for unrelated treatment. Plaintiff’s affidavit alleges that she receives part of her income from “Welfare, Food Stamps, S/S, Pensions, etc.”
While N.C. Gen. Stat. § 1-110 limits the trial court’s discretion in ruling on a motion to proceed informa pauperis, no evidence in the record shows and the trial court made no findings of fact that plaintiff receives “food stamps,” “Work First Family Assistance,” or “Supplemental Security Income” to comply with any of the criteria listed in N.C. Gen. Stat. § l-110(a). Plaintiff’s affidavit does not specify or allege that she receives one or all of these statutorily enumerated factors. Plaintiff’s affidavit only indicates that she possibly receives “Welfare, Food Stamps, S/S, Pension, etc.” Plaintiff does not argue on appeal that she receives any of these enumerated criteria set forth in the statute to require the court to authorize her to sue as an indigent. The trial court possessed discretion to grant or deny plaintiff’s request and to not authorize her to proceed as an indigent.
Our Supreme Court has recognized that a party may not file a motion to proceed informa pauperis “as a subterfuge to escape pay*333ment of costs which otherwise might be taxed against the [party].” Perry v. Perry, 230 N.C. 515, 515-16, 53 S.E.2d 457 (1949). Here, the trial court found and the evidence shows plaintiff filed her motion to proceed informa pauperis and affidavit after the jury returned a verdict for defendants and after Leak had filed her motion for costs. The trial court’s order concluded:
According to North Carolina law, a motion to proceed as an indigent is not to be used as “a mere subterfuge to escape payment of costs which might otherwise be taxed against the [party].” Perry v. Perry, 230 N.C. 515, 53 S.E.2d 457 (1949).
We agree with the trial court that the timing of plaintiffs motion tends to show she filed it as a subterfuge.
The dissenting opinion suggests that the timing of plaintiffs motion is not indicative and would hold that there is no time limitation imposed by N.C. Gen. Stat. § 1-110. We disagree. The statute permits the filing of a motion when a plaintiff is “unable to advance the required court costs.” N.C. Gen. Stat. § l-110(a) (emphasis supplied). Upon a proper showing, the trial court then has the discretion to “authorize a person to sue as an indigent.” Id. (emphasis supplied). The legislature’s use of the words “to sue” and “advance” clearly indicate its intent that a motion to proceed informa pauperis should be filed in “advance” of filing suit. Our State Constitution provides that “all courts shall be open.” N.C. Const, art. 1, § 18. N.C. Gen. Stat. § 1-110 furthers this right by allowing access “to sue” in our courts, notwithstanding a party’s inability to “advance” court costs.
In her affidavit, plaintiff stated, “to require me to pay court costs and to post a bond with the appellate court would create undue and inappropriate hardship upon me ....” Plaintiff’s own affidavit clearly shows that she requested the court to declare her indigent to avoid paying court costs after the trial and not to be relieved from advancing costs required by the court to initially file her action.
Further, N.C. Gen. Stat. § 1-110 provides that the trial corn! may relieve plaintiff from advancing the required court costs, but does not relieve a party from ultimate liability to pay costs. See N.C. Gen. Stat. § 1-110 (2003). Plaintiff cites no statute or case law to support her notion that filing a motion to proceed informa pauperis relieves her of her ultimate liability for costs. The dissenting opinion cites Draper v. J.A. Buxton & Co., 90 N.C. 182 (1884), and Clark v. Dupree, 13 N.C. 411 (1830), as authority to conclude that a pauper is relieved from lia*334bility for costs. These cases, however, involved a distinctly different statute from our current statute that allows parties to proceed in forma pauperis. When the Supreme Court handed down its decision in Draper, the statute read, “THE CODE, sec. 212, provides that, ‘whenever any person shall sue as a pauper, no officer shall require of him any fee, and he shall recover no costs' ” Draper, 90 N.C. at 185. Our Supreme Court’s interpretation over a century ago of a different statute is not controlling when our current statute gives no relief from the payment of costs. N.C. Gen. Stat. § 1-110 only relieves a pauper from advancing costs when filing a suit.
Even if evidence supports a finding that plaintiff should have been authorized to proceed as an indigent, the statute grants relief only for the advancement of costs and does not relieve her of the ultimate liability to pay. The trial court did not abuse its discretion in concluding that plaintiff “is not incapable, by reason of poverty, to advance the costs of this proceeding.” Plaintiff has not shown that the trial court’s ruling was “manifestly unsupported by reason,” or “so arbitrary that it could not have been the result of a reasoned decision.” Briley, 348 N.C. at 547, 501 S.E.2d at 656. This assignment of error is overruled.
IV. Motions for Costs
[2] Plaintiff argues the trial court erred in granting defendants’ motions for costs. We disagree.
In her brief, plaintiff “restates and incorporates” her arguments in her first assignment of error, as well as the “arguments made in her brief filed in Case No. COA03-181.” This Court has already ruled on No. COA03-181 in Griffis I, and we held the trial court did not err and affirmed its denial of plaintiff’s motions for judgment notwithstanding the verdict and new trial. Except for plaintiff’s restatement and incorporation of earlier arguments, plaintiff has failed to cite any authority for this assignment of error as required by N.C.R. App. P. 28(b)(6) (2003). For these reasons, we have already ruled on plaintiff’s arguments regarding this assignment of error, and this assignment of error is dismissed.
The defendants at bar filed separate motions requesting the trial court to tax costs against plaintiff. In Whedbee, our Supreme Court ruled on a similar issue, wherein plaintiff had assigned error to the trial court’s “taxing the costs against him, after having been allowed to sue as a pauper.” 191 N.C. at 259, 131 S.E. at 654. The Court found no error at trial and concluded, “the matter of taxing costs is a col*335lateral matter [to requiring plaintiff to pay a deposit], and, if any injustice has been done to the plaintiff in this respect, he must make a motion as provided by law for the retaxing or proper taxing of costs.” Id. at 257, 131 S.E. at 655.
Here, plaintiff did not file a separate motion for “the retaxing or proper taxing of costs.” Id. Her motion to proceed informa pauperis was filed in response to defendants’ motions for costs. The trial court did not abuse its discretion in denying this motion. Further, our Supreme Court held in Whedbee that the trial court’s discretion in granting or denying these motions runs throughout the trial. Id. at 257, 131 S.E. at 654.
Plaintiff does not argue the trial court abused its discretion in taxing the costs against her. “The awarding of costs to a defendant in a personal injury suit... may be allowed in the court’s discretion under N.C.G.S. § 6-20 (1986).” Sterling v. Gil Soucy Trucking, Ltd., 146 N.C. App. 173, 180, 552 S.E.2d 674, 679 (2001). “The court’s discretion under N.C.G.S. § 6-20 is not reviewable on appeal,” where the court specifically states the costs awarded defendants were taxed against plaintiff in the court’s discretion. Id. Here, the trial court clearly indicated it was taxing costs against plaintiff in its discretion pursuant to N.C. Gen. Stat. § 6-20.
Additionally, the Lazaroviches based their motion for costs on N.C.R. Civ. P. 68 (2003) (“Rule 68”). Rule 68 allows a party to recover costs when that party makes an offer to settle that is rejected by the opposing party. The rule states, “[i]f the judgment finally obtained by the offeree is not more favorable than the offer, the offeree must pay the costs incurred after the making of the offer.” N.C.R. Civ. P. 68(a) (2003) (emphasis supplied). The Lazaroviches filed and served plaintiff with an offer of judgment in the lump sum amount of $500.00. At trial, the jury found that plaintiff was not injured by the negligence of Lazarovich. Rule 68 required the trial court to tax plaintiff with the Lazaroviches’ costs of proceeding with trial after plaintiff rejected this offer and received a less favorable result at trial. The dissenting opinion fails to address the motions for costs. This assignment of error is overruled.
V. Conclusion
The trial court did not abuse its discretion in denying plaintiff’s motion to proceed informa pauperis, filed following a trial and jury verdict and made in response to Leak’s motion for costs. The evidence shows that plaintiff has attempted to use her motion as a “sub*336terfuge to escape payment of costs.” Perry, 230 N.C. at 515-16, 53 S.E.2d at 547. Our Supreme Court has clearly spoken on this issue and has long recognized that “the right to sue as a pauper is a favor granted the plaintiff, and is in the power and discretion of the Court.” Dale, 119 N.C. at 491-92, 26 S.E. at 28.
Statutes allowing a party to proceed in forma pauperis are a “means of protection to the poor.” Id. at 493, 26 S.E. at 28. Here, plaintiff has failed to show that the trial court abused its discretion in concluding that she was attempting to use this “means of protection” as a subterfuge to avoid paying costs. Id. Plaintiff’s appeal is without merit. The orders of the trial court are affirmed.
