If a child is born to a surrogate mother or surrogate carrier pursuant to a surrogate parentage contract, and there is a dispute between the parties concerning custody of the child, the party having physical custody of the child may retain physical custody of the child until the circuit court orders otherwise. The circuit court shall award legal custody of the child based on a determination of the best interests of the child. As used in this section, "best interests of the child" means that term as defined in section 3 of the child custody act of 1970, Act No. 91 of the Public Acts of 1970, being section 722.23 of the Michigan Compiled Laws.
