Section 21 Discharge and variation of maintenance orders registered in superior courts.

The registration of a maintenance order in a superior court under this Part of this Act shall not confer on that court any power to vary or discharge the order, or affect any jurisdiction of the court in which the order was made to vary or discharge the order.

Where a maintenance order made in Scotland is for the time being

the person liable to make payments under the order may, upon application made to that court in the prescribed manner, adduce before that court any evidence upon which he would be entitled to rely in any proceedings brought before the court by which the order was made for the variation or discharge of the order.

A court before which evidence is adduced in accordance with the foregoing subsection shall cause a transcript or summary of that evidence, signed by the deponent, to be sent to the prescribed officer of the court by which the order was made; and in any proceedings before the last-mentioned court for the variation or discharge of the order, the transcript or summary shall be evidence of the facts stated therein.
