Answer
Based on official Jordanian legal texts
Jordanian law allows an adjudged maintenance to be increased if the circumstances on which it was assessed have changed. Article 64 of the Personal Status Law provides that maintenance is assessed according to the payer's means, whether comfortable or constrained, and allows it to be increased or decreased as circumstances change; so if the husband's means improve or the entitled person's need grows, an increase may be sought.
Article 202, however, bars hearing a claim to increase a wife's or relatives' maintenance before a year has passed since it was assessed, unless exceptional circumstances arise that justify earlier review. The aim of this restriction is the stability of rulings and avoiding repeated litigation without cause.
An increase in maintenance is therefore legally possible on a material change in circumstances, with that change proven before the Sharia Court by evidence.
Assessing whether a material change exists and the amount of the increase remains within the court's competence on the facts of each case, and the outcome is not guaranteed in advance.
This is a general explanation based on Jordanian Personal Status Law and does not replace advice from a qualified lawyer in a specific dispute.
