A divorce decree incorporated by reference a separation agreement providing for alimony and child support, and the husband failed to make payments required by the agreement. We hold that the Probate Court had jurisdiction to enforce payment by contempt proceedings, but that the judge erred in failing to consider modification of the decree. The decision in
Gunter
v.
Gunter,
The decree of divorce nisi, entered April 9, 1970, awarded custody of the parties’ five children to the wife and added, “and all other provisions are provided for in an agreement dated February 11, 1970 incorporated and filed herewith.” The agreement provides, among other things, that the husband will pay to the wife $500 a month for her support and maintenance so long as she remains unmarried and $200 monthly for each child for child support and maintenance. After two years the latter payments become $240 monthly for each child. These payments “are based on the Husband’s present income of approximately $3,200 per month gross. In the event of change of circumstances of the children’s needs and requirements for care and support either party may petition any court of competent jurisdiction for a determination and order on the issue of child support.” If the husband’s gross income increases, he is to pay the wife no less than thirty per cent of the net excess after taxes. The provisions of the agreement “may be incorporated” in a divorce decree but the agreement “shall not be merged” in any such decree and “shall survive the same.”
On February 15, 1973, the wife brought a petition for contempt, alleging nonpayment, and on June 21, 1973, “after hearing and by agreement” the arrearages were *610 found to be $7,200 and execution was issued for that amount. On March 25, 1974, the wife brought a second petition for contempt, claiming total arrearages in excess of $13,000, including the $7,200. The judge, as matter of law, denied the husband’s motion for a temporary modification, and referred the contempt petition to an auditor. On October 21, 1974, the judge confirmed the auditor’s report, found the husband in contempt, and ordered him committed to jail for six days and then for thirty consecutive weekends “until he shall purge himself of said contempt by payment of the sum of $13,854.64.” The husband appealed, and a single justice of this court stayed the commitment to jail on condition that the husband pay $1,000 a month pending the appeal. We transferred the case to this court on our own motion.

Modification.
“It is settled that a separation agreement does not deprive the Probate Court of its power to modify its decree relating to alimony for the wife or support for the children.”

Contempt.
There was no attempt here to meet the procedural requirements for criminal contempt, and the case must be treated as one of civil contempt. A person judged in civil contempt may not be sentenced to prison for failure to pay a compensatory sum of money if he shows that he is unable to comply.
