Opinion
Kathryn T. Taylor (wife) appeals from a decree entered by the Circuit Court of the City of Norfolk (trial court) on December 6, 1988. The decree denied her request that Charles F. Taylor (husband) be required to increase the amount of child support. The decree also denied her request that husband pay the sum of $1,000 for dental bills incurred on behalf of their daughter, Jacquelyn, and her request for a judgment against husband for sums alleged to be due as support payment arrearages and unpaid college costs.
After a marriage of approximately sixteen years, the parties separated on July 30, 1977. On January 3, 1978, they executed a separation agreement which was approved and incorporated in a final decree of divorce entered on December 26, 1978. Wife’s requests are founded on provisions contained in that decree.
I. The Accrued Installments
The agreement approved by and incorporated in the divorce decree contained the following provisions:
Husband will pay to Wife as support and maintenance for said infant children, beginning January 1 1978, the sum of Six Hundred ($600.00) Dollars monthly; and the Husband shall claim the children for income tax purposes.
Neither the agreement nor the decree apportioned the payments. Likewise, neither provided for a reduction when any of their three children attained a particular age or became emanci

pated. When the agreement’s provisions were incorporated in the divorce decree they became a unitary award. When such agreements are made a part of the divorce decree it is the decree that is being enforced, not the agreement,
see Doherty
v.
Doherty,
In a letter dated May 5, 1988, the trial court advised the parties that the “unitary award” for the children, given its “most reasonable meaning,” disclosed an intent that the gross sum of $600 per month would be reduced by $200 as each child attained the age of eighteen years and, for that reason, declined to grant wife a judgment for the sums husband had failed to pay. We hold that it was error to refuse to grant the relief sought by wife as to child support arrearages. Payments required by the original decree of divorce become vested as they accrue and the court is without authority to make any change as to past due installments.
See Cofer
v.
Cofer,
Under our ruling in Cofer v. Cofer,205 Va. 834 , 839,140 S.E.2d 663 , 666, a court is without authority to modify its decree retroactively and relieve the husband of the obligation to pay past due installments. As we indicated in Newton v. Newton, supra, a divorced husband must pay “according to the terms of the decree.” When conditions changed, Fearon’s *684 remedy was to apply to the court and have it modify the terms of the decree.

II. Child Support
As aforenoted, both the agreement and the divorce decree required husband to pay the unitary sum of $600 per month as child support. In the proceeding appealed from, wife petitioned the trial court to increase that sum and husband asked that it be reduced. The trial court denied each of these requests, yet entered a decree which effectively granted relief to husband by requiring him to pay only $200 per month for the remaining infant child. In fixing $200 per month as the sum for child support the trial court advised the parties that no change would be appropriate because of wife’s “comparative wealth.” It is apparent that the trial court’s decision was made upon the erroneous belief that the divorce decree required husband to pay only $200 per month as child support. Moreover, nothing contained in the record indicates that any consideration- was given to the guidelines set forth in Code § 20-108.2. Application of the provisions of that code section is not limited to the initial support hearing.
For the reason stated, the judgment requiring husband to pay $200 per month child support is reversed and this cause remanded with direction that the issue of an appropriate amount for support for the remaining infant child be reviewed and determined pursuant to the guidelines and such other relevant facts as may be presented by the parties.
III. College and Dental Expenses
We further hold that the record supports the trial court’s finding that the terms of the separation agreement incorporated in the divorce decree required husband to pay only those college and dental expenses incurred during the period necessary to obtain the degree for which the child was enrolled. Accordingly, it was not *685 error for the trial court to decline to enter a judgment for the sums wife sought for those expenses.
For the reasons stated, the judgment of the trial court is reversed as to arrearages and support for the remaining infant child and remanded for further proceeding consistent with this opinion. The judgment is affirmed as to its denial of the petition for reimbursement for college and dental expenses.
Reversed in part, affirmed in part, and remanded.
