The agreement to reimburse shall provide that the filing of notice thereof as hereinafter provided, is to have the same force and effect as a judgment of the Superior Court. It shall contain therein a release of dower or curtesy, as the case may be, of the spouse of the recipient of old age assistance, and the spouse shall agree to reimburse the county welfare board for all advances made to the recipient. Such release and joinder shall be as valid and effectual as if the spouse had joined the recipient in a conveyance of the property to a third person, and the grant of old age assistance, being contingent upon such joinder by the spouse, shall be good and valuable consideration therefor. Old age assistance shall not be granted to any applicant without joinder by the spouse in the agreement to reimburse except upon the showing of good and sufficient cause as the State Division shall by regulation define.
