A domestic obligation which a trial court has not ordered pursuant to statutory authority may become enforceable when the parties agree to it, and the court approves the agreement and incorporates it into an order of the court. Weiss v. Varnadore, 246 Ga. App. 654, 657 ( 541 SE2d 448) (2000). Parties may enter into an agreement regarding child support obligations as long as it is specific, does not contravene a statute, and does not violate public policy.

Thus, Mia Luke has failed to show that the visitation order is deficient as claimed. Compare Rainey, supra; Weiss v. Varnadore, 246 Ga. App. 654, 660 ( 541 SE2d 448) (2000) (vacating visitation order, where it was not possible from the state of the record and the order of the court to determine what standard the trial court applied in its order and what evidence or agreement it relied upon in doing so). 3. Mia Luke argues that the trial court's ruling that it was in the children's best interest to grant Pete Luke visitation was not supported by the record.

Id. Id. at 194 (2) (c); see also Weiss v. Varnadore, 246 Ga. App. 654 ( 541 SE2d 448) (2000) (approving award of joint custody of child to parent and grandparent, upon consent of parent or upon waiver by parent of constitutionally protected parental rights, provided trial court determines that award is in best interest of child). While there are, to be sure, many instances where the grandparent-grandchild bond is beneficial to the child, we have found, and the parties cite, little evidence that this is most often the case.
