Appellant, Wilfred T. DeMoranville, and respondent, Claire T. Tetreault, formerly Claire T. DeMoranville, were married in 1952 and lived together in Massachusetts for a number of years. To this marriage five children were born but then the parties separated and Wilfred found his way to Missouri where he obtained a divorce in 1967. He was ordered to pay Claire $15.00 per week per child for support. No support payments were made after August of 1968 and Claire, rather than attempting long-range collection tactics, sought public assistance in Massachusetts, which she apparently received for her children during the time they were at home and dependent upon her. By reason of having received public assistance, her right to the support payments was assigned by law to the Massachusetts Department of Public Welfare.
