106 C.M.R. 703.360
(A) Requirements. Temporary absences from Massachusetts, with returns to Massachusetts, or intent to return when the purpose of the absence may have been accomplished, do not interrupt continuity of residence. Temporary absences include reasons such as health, business, school, or family commitments. An absence of more than 30 calendar days or 90 days in aggregate over the course of a calendar year shall creates a rebuttable presumption that Massachusetts residency has been abandoned and eligibility for assistance has ended. The client may disprove this presumption as follows:
(B) Absence in Excess of 30 Days. If a client is absent for more than 30 calendar days, and continues to receive assistance, the worker shall notify the appropriate state agency in the state where the client is temporarily residing. The notice shall include: the client’s name, Social Security Number, previous Massachusetts address, current address, if known, and anticipated length of the absence.
temporary nature of the absence may include, but is not limited to, medical documentation, a short-term business contract or school documents. Evidence to substantiate intent to retain residency includes any of the documents listed in 106 CMR 706.400(C)(1)(b).
