If, at any time, the High Court is satisfied that a party to proceedings is unable to pay—
a sum recovered against him (by way of satisfaction of the claim or counterclaim in the proceedings or by way of costs or otherwise), or
any instalment of such a sum,
the court may stay the execution of any writ of control issued in the proceedings, for whatever period and on whatever terms it thinks fit.
The court may act under subsection (1) from time to time until it appears that the cause of the inability to pay has ceased.
In this section a party to proceedings includes every person, whether or not named as a party, who is served with notice of the proceedings or attends them.
