(a) Upon the filing of a petition authorized by the Uniform Interstate Family Support Act, an initiating tribunal of this state shall forward three copies of the petition and its accompanying documents:
(1) to the responding tribunal or appropriate support enforcement agency in the responding state; or
(2) if the identity of the responding tribunal is unknown, to the state information agency of the responding state with a request that they be forwarded to the appropriate tribunal and that receipt be acknowledged. (b) If a responding state has not enacted the Uniform Interstate Family Support Act or a law or procedure substantially similar to the act, a tribunal of this state may issue a certificate or other document and make findings required by the law of the responding state.
