This mаtter is before us on cross-appeals from an order of the Family Division of the Superior Court granting in part and denying in part a motion to increase child support. Mr. Cooper appeals the increase in child support and award of attorney’s fees; Mrs. Cooper appeals the allocation of payments for psychiatric treatment for one of the children. In the interest of brevity, we will refer to Richard M. Cooper as appellant and tо Sabina K. Cooper as appellee.
I
The parties were married in 1965 and have two children, ages nine and thirteen, from the marriage. In 1978, the parties еntered into a comprehensive Separation and Property Settlement Agreement (“the Agreement”) by mutual consent. Appellee later sued for divоrce on the ground of voluntary separation and a judgment for absolute divorce was granted on May 16, 1978. This judgment ratified, confirmed and incorporated, but did not merge the Agreement.
The Agreement provided inter alia for joint custody of the two minor children, with residential custody to appellee. In addition, appellant agreed to pay the sum of $666 per month as undifferentiated alimony and child support. On December 21, 1981, the court, upon appellee’s motion, increased combined alimony and child support payments to $1,445 per month. Further, the court denied appellee’s claim under the Agreement for unpaid psychiatric bills. Lastly, the court ordered аppellant to contribute $3,774.87 towards appellee’s legal fees: $3,274.87 for the expenses related to the motion and $500 for previous legal fees as required under the Agreement. 1 For the *880 reasons stated herein, we agree with appellant that the trial court erred in modifying the level of alimony/support payments provided for in the Agreement. Therefore, we reverse in part and remand this case to the trial court for proceedings consistent with this opinion. 2

The trial court, in its order, stated:
“Modification of a final decree of child support is justified only when the proponent of change bears the burden of proof that there has been a material change in the needs of the child or the ability of the parents to pay,” Tennyson v. Tennyson, D.C.App.,381 A.2d 264 , 265 (1977); Hamilton v. Hamilton, D.C.App.,247 A.2d 421 (1968). In determining whether circumstances have materially changed, there must be a comparison between the date of the original order and the date of the hearing. Mozick v. Mozick, D.C.App.,245 A.2d 643 (1968); Sheridan v. Sheridan, [267 A.2d 343 (D.C.1970)].
The court further noted that despite a policy favoring the private resolution of domestic disputes,
Lanahan
v.
Nevius,
Where the level of child support payments has been set by the court pursuant to a hearing, the standard by which to determine whether modificаtion is justified is that used by the trial court.
See Tennyson v. Tennyson, supra,
Generally, separation agreements are enforced “[i]n the absence of fraud, duress, concealment or
overreaching....” Lanahan v. Nevius, supra,
In modifying the level of alimony/support payments set by the prior Agreement, the trial court applied the standard appropriate when payments previously have been set by a court. Because the standards involve components which are so distinct as to lead, conceivably, to different results, we cannot affirm the trial court’s award increasing the level of alimony/support payments. We, therefore, reverse this award and remand for reconsideration consistent with this opinion.
Apрellant also challenges the award of attorney’s fees. In light of our reversal, we vacate the award to appellee of $3,274.87 in attorney’s fees related to her motion and remand for further consideration.
See Owen v. Owen,
So ordered.
Notes
. In an order dated April 13, 1982, the trial court denied appellant’s motion to reconsider the December 21 оrder; and modified this order with respect to the payment of psychiatric *880 bills. Further, it modified its visitation order of December 7, 1981.
. Appellee has cross-appealed the trial court’s order with regard to the sharing of psychiatric expenses allowed for one of the children. Ap-pellee made a claim for out-of-pocket uninsured expenses for psychiatric treatment and related insurance costs. The Agreement provides that appellant is not responsible for such expenses unless he has given prior written approval to appellee. The trial court found that appellant disapproved of the therapy, and therefore denied the claim, under the Agreement, for unpaid psychiatric bills. There is support in the record for this finding. Therefore, we affirm this portion of the trial court’s order. D.C.Code § 17-305(a) (1981).
. We note that in the instant case the Agreement contemplated that appellant might be making three or four times as much income as appellee during the life of the Agreement. It provides for a yearly increase in alimony/support payments whiсh is tied to the Consumer Price Index. This cost-of-living adjustment should be considered by the trial court in determining whether there has been a change in circumstances which was unforeseen at the time the Agreement was entered.
