In applying and construing this uniform act, consideration must be given to the need to promote uniformity of the law with respect to its subject matter among states that enact it.

    This act applies to proceedings begun on or after the effective date of this act to establish a support order or determine parentage of a child or to register, recognize, enforce, or modify a prior support order, determination, or agreement, whenever issued or entered.

    If any provision of this act or its application to any person or circumstance is held invalid, the invalidity does not affect other provisions or applications of this act which can be given effect without the invalid provision or application, and to this end the provisions of this act are severable.

    The uniform interstate family support act, 1996 PA 310, MCL 552.1101 to 552.1901, is repealed.

    This act takes effect January 1, 2016.
