Missouri Revised Statutes Title XXX. Domestic Relations § 452.805. Filing of certified copy of custody decree

1. A certified copy of a custody decree of another state may be filed in the office of the clerk of any circuit court of this state. The clerk shall treat the decree in the same manner as a custody decree of the circuit court of this state. A custody decree so filed has the same effect and shall be enforced in like manner as a custody decree rendered by a court of this state.

2. A person violating a custody decree of another state which makes it necessary to enforce the decree in this state may be required to pay necessary travel and other expenses, including attorneys' fees, incurred by the party entitled to the custody or the party's witnesses.

3. A court of this state shall recognize and enforce a child custody determination of a court of another state if the latter court exercised jurisdiction that was in substantial conformity with sections 452.700 to 452.930 or the determination was made under factual circumstances meeting the jurisdictional standards of sections 452.700 to 452.930 and the determination has not been modified in accordance with sections 452.700 to 452.930.

4. A court may utilize any remedy available under other law of this state to enforce a child custody determination made by a court of another state. The procedure provided by sections 452.740 to 452.845 does not affect the availability of other remedies to enforce a child custody determination.
