A judge of the Probate Court for Norfolk County has reported (G. L. c. 215, § 13) a question concerning his power to modify a decree so as to require a divorced father to make increased payments for the support of his minor children. The decree of divorce provides that support of the minor children “is in accordance with a trust agreement dated June 12, 1967, filed herewith by the parties, which is incorporated and made part of this decree by reference, until the further order of the Court.” The former wife, since remarried, sought an order increasing the husband’s support obligations for their minor children. We conclude that the judge has the authority to order a modification of child support provisions in this circumstance.
*434
The decree contained an order for the support of the minor children. The provision in the decree that support should be as provided in the separation agreement “until the further order of the Court” shows a clear intention on the part of the judge who entered the decree that the decree should and did contain an order for support of the minor children. However, we do not rest our decision on that language. The incorporation of the agreement into the decree was sufficient in itself to cause the decree to contain an order for support, which in turn could be modified. We so held recently in

Salvesen,
Although what we have said is sufficient to dispose of the question reported, we think it appropriate to discuss the relationship of separation agreements and orders entered in connection with judgments of divorce. 3 The sub *435 ject is one of daily concern to the judges of the Probate Courts of the Commonwealth. Two other cases decided by us today involve the relationship of a separation agreement and a divorce judgment containing a support order. See Ryan v. Ryan, ante, 430 (1976), and Ross v. Ross, post, 439 (1976).
There is, of course, no conflict if a separation agreement was not intended to survive the entry of the divorce judgment.

v.
Fabrizio,
A Probate Court support order may be modified to require a lower payment than that agreed to between the parties in a separation agreement which is intended to survive a divorce judgment.
Wilson
v.
Caswell,
We consider next the consequences of a support order
*436
which directs the payment of support in an amount in excess of that provided in a separation agreement. As we have held today, the terms of a separation agreement cannot bar a Probate Court judge in all circumstances from entering an order for payments in excess of those expressed in the separation agreement.
Ryan
v.
Ryan, supra
at 432, and cases cited. What then is the consequence of an agreement by one spouse to accept the support payments set forth in a separation agreement in full satisfaction of all future claims for support or of an agreement by one spouse to hold the other harmless from the consequences of a future increase in support obligations resulting from a court order? We have intimated that such agreements are valid and enforceable. See
Schillander
v.
Schillander,
We see no reason why parties to a separation agreement which anticipates that the marriage will be terminated by divorce may not agree to a permanent resolution of their mutual rights and obligations, including support obligations between them. If a judge rules, either at the time of the entry of a judgment nisi of divorce or at any subsequent time, that the agreement was not the product of fraud or coercion, that it was fair and reasonable at the time of entry of the judgment nisi, and that the parties clearly agreed on the finality of the agreement on the subject of interspousal support, the agreement concerning in
*437
terspousal support should be specifically enforced, absent countervailing equities. This has been the result indicated by this court numerous times in the past. See
Reeves
v.
Reeves,
An agreement to fix a spouse’s support obligation for minor children stands on a different footing. Parents may not bargain away the rights of their children to support from either one of them. Ryan v. Ryan, supra at 432, and cases cited. 2 J.F. Lombard, Family Law § 1258 (1967). However, an informed agreement made by the parents, allocating responsibility for support of a minor child, should be upheld as far as possible as between the contracting parties, assuming the agreement is free from fraud and coercion and was fair and reasonable at the time the divorce judgment was entered. But a Probate Court support order may recast the burden of support for a child, as expressed in a separation agreement, for example, where (a) a support order would be entered or modified, as the case may be, in the absénce of such an agreement and (b) *438 the level of available support for the child is inadequate in the circumstances because one former spouse is incapable financially of meeting his or her obligation for child support expressed in that agreement. Although the separation agreement will not be enforced specifically in that circumstance, the spouse whose support obligation is increased by the judge’s order beyond that spouse’s contractual obligation has a claim for breach of contract, which may have no practical current value because of the financial condition of the other spouse.
We believe that all aspects of the dispute between the former spouses should be resolved in one proceeding. If one spouse seeks modification of a support order so as to depart from the terms of the separation agreement, the other spouse should raise the availability of the separation agreement as a potential bar in the same proceeding. Probate Courts have jurisdiction over “matters of equity cognizable under the general principles of equity jurisprudence ____” G. L. c. 215, § 6, as appearing in St. 1973, c. 1114, § 63. Although rule 13 of the Massachusetts Rules of Civil Procedure,
The case is remanded to the Probate Court for further proceedings consistent with our opinion.
So ordered.
Notes
The separation agreement contained a provision that “the court may be requested to enter a decree incorporating this agreement in lieu of orders relative to property, maintenance or alimony.” We do not know what the judge was requested to do, but he did not omit a provision for support in his order, relying on the agreement to cover the subject. He made a specific order for support.
This opinion should not be taken, however, to imply that the Probate Court lacks jurisdiction to order appropriate child support payments if a judgment nisi of divorce contains no order concerning child support. See
Kates
v.
Kates,
Under present practice, a decree nisi of divorce is called a judgment nisi of divorce. We shall refer to such decrees and judgments by the current designation.
Such finality, after approval of the agreement by the judge and entry of judgment nisi, exists under the recently enacted so called no-fault (“irretrievable breakdown”) divorce statute. See G. L. c. 208, § 1A, inserted by St. 1975, c. 698, § 2. We do not consider here the consequences of such a divorce judgment and a separation agreement made and approved under that statute.
