voluntary sale or upon conclusion of the pending partition action), plaintiff shall pay defendant a monthly rent allowance in lieu of the carrying charges and utilities specified in the judgment. The order then stated: "This arrangement is to continue for so long as at least one of the two daughters * * * shall reside with the defendant. In any event, this provision shall terminate when the youngest child * * * attains the age of 21 years”. The partition action was decided in favor of plaintiff and, when one of the two younger children reached the age of 21 and no longer resided with defendant, plaintiff again moved for modification of the judgment as to support of that child and as to the rent allowance. Special Term, by order entered April 30,1971, granted a decrease of child support from $110 to $55 a week, but denied the latter portion of the motion as premature and "without prejudice to a renewal at the proper time.” Defendant moved out of the former marital home in late April, 1974, shortly before consummation of the sale of the house in May, 1974. She signed a two-year lease for a four-room apartment in Glen Cove at a monthly rental of $320. (The monthly carrying charges for the marital home were agreed by the parties to have been $562.) The apartment contains one bedroom. At that time, Susan, the youngest daughter, was 19 years of age and a student at the State University of New York in Binghamton. She was spending nine months a year at school. During her summer vacations she was staying with her mother, with intermittent stays at the home of her father and her friends. Starting in May, 1974 plaintiff failed to pay the monthly housing allowance ($562) to defendant. In July, 1974 defendant made a motion in the instant case, requesting,
inter alia, sequestration because of his failure to make the payments. Plaintiff cross-moved for elimination of child support beginning September 1, 1974 (that being the effective date of the newly amended section
2 of the Domestic Relations Law, which redefined "minor” and "infant” as a person under the age of 18 years) and for modification of the divorce judgment "with respect to the amount of rent allowance for the children”. As to the latter request, plaintiff claimed that the rent allowance was a form of child support for a minor. He asserted that since Susan had reached her majority by virtue of the amended statute on September 1, 1974, defendant was no longer entitled to receive a housing allowance ostensibly on Susan’s behalf, especially since defendant’s housing expense was in no way increased by Susan’s need for housing. Plaintiff argued that the provision in the March 18, 1971 order that he pay a rent allowance to defendant until Susan "attains the age of 21 years”, was inserted at a time when 21 was the age of majority and that what was really intended was "the age of majority”, whatever that may turn out to be. Special Term held that plaintiff could properly cease making the child support payments of $55 a week, but that, since Susan’s legal residence was still with her mother, the order of March 18, 1971 remained effective, pursuant to its terms, until Susan became 21. On reargument Special Term stated that it "saw no reason to disturb this arrangement”. We do not believe that one’s obligation to reimburse his former wife for housing expenses because she provides a legal residence for their daughter should depend on whether a pre-1974 order stated that such obligation should terminate when the child attains the age of 21 years or majority. We have no way of knowing whether the author of the order gave specific attention to whether the child’s needs required such payments until she was 21 or whether 21 was merely intended as a synonym for the age of majority, with no special concern as to the specific age at which majority is reached. We believe that section
240 of the Domestic Relations Law mandates that modification of child support
