This is an appeal from the trial court’s order granting appelleedefendant Larry Bartis’ motion to enforce a settlement agreement. Upon review of the record, we affirm the trial court’s order.

On a motion to enforce a settlement agreement, we construe the evidence to uphold the trial court’s judgment. Morrow v. Vineville United Methodist Church, 227 Ga. App. 313, 317 (489 SE2d 310) (1997). We will not disturb a trial court’s findings thereon unless “clearly erroneous.” Id. The record in this case shows that, while driving his car, appellant-plaintiff Louis L. Ligón III, was hit from behind by a car driven by Bartis. Ligón hired attorney James Farris to represent him in a personal injury action against Bartis. Bartis hired attorney Lee Welborn to defend against the action. The case pro *329 ceeded to discovery. 1

Following discovery, attorneys Farris and Welborn entered into settlement negotiations. The next day, on December 22, 1998, Farris informed Ligón of the strengths and weaknesses of his case and that defendant was offering $23,750 in settlement and satisfaction of Ligon’s personal injury claim. Ligón asserts that, when Farris told him of the settlement offer and terms, Ligón stated, “I don’t know what else is there to do?” The following day, December 23, 1998, Farris notified Welborn that Ligón had accepted the settlement offer of $23,750. The settlement was confirmed in writing in a January 14, 1999 letter written by Welborn to Farris.

Approximately a month after Farris settled the case, Ligón telephoned Farris and told him “that he should not proceed any further with any settlement negotiations or proceedings.” Apparently, Ligón had consulted with other attorneys and decided that Farris had misled him as to whether settlement was in his best interest. Ligón fired Farris; he refused to sign the settlement papers. Defendant Bartis, through his attorney, filed a motion to enforce the settlement. A hearing was held on the motion, and on May 19,1999, the trial court ordered Ligón to sign the settlement agreement and to file a dismissal of his personal injury claim. Thereafter, Ligón filed an “Affidavit of Truth in Matter of Settlement Offer” wherein he refused to follow the trial court’s order. Bartis, through attorney Welborn, filed a petition to hold Ligón in contempt. A hearing was held on the petition, after which the trial court vacated its earlier order, enforced the settlement agreement again, and entered judgment in favor of Ligón in the amount of $23,750, per the terms of the agreement. From this order, Ligón appeals. Held:

Under Georgia law [a private] attorney of record has apparent authority to enter into an agreement on behalf of his client and the agreement is enforceable against the client by other settling parties. The authority may be considered plenary unless it is limited by the client and that limitation is communicated to opposing parties.

(Citations and punctuation omitted.) City of Atlanta v. Black, 265 Ga. 425, 427 (457 SE2d 551) (1995).

Here, there is no dispute as to the existence of the settlement agreement and its terms. The agreement and its terms were memorialized in writing, and “letters or documents prepared by attorneys *330 which memorialize the terms of the agreement will suffice.” Brumbelow v. Northern Propane Gas Co., 251 Ga. 674, 676 (308 SE2d 544) (1983). Moreover, Ligón admits that his attorney entered into the settlement agreement for $23,750. Here, the sole dispute is Ligon’s contention that Farris did not have his authorization to enter into such agreement.

“[W]here there is no challenge to the existence or the terms of an agreement but only to an attorney’s authority to enter into it, the client is bound by its terms.” Brumbelow v. Northern Propane Gas Co., supra at 676. Ligon does not assert that his attorney’s alleged lack of authority was ever communicated to the opposite party. Nor does the record show such communication was ever made. In this case, Ligon’s remedy, “where there have been restrictions not communicated to the opposing party, is against the [private] attorney who overstepped the bounds of his agency, not against the third party.” Id. at 675. See also City of Atlanta v. Black, supra at 432 (Carley, J., dissenting). Accordingly, in light of the fact that the existence and terms of the agreement were established in writing and are not in dispute, the trial court did not err in enforcing the settlement agreement and entering judgment for plaintiff in the amount of $23,750. Commercial Union Ins. Co. v. Marco Transp. Co., 211 Ga. App. 844 (1) (440 SE2d 730) (1994); compare LeCroy v. Massey, 185 Ga. App. 828 (366 SE2d 215) (1988). 2

Judgment affirmed.
