Answer
Based on official Jordanian legal texts
Relatives' maintenance under Jordanian law is a financial obligation falling on a solvent relative toward an insolvent relative unable to earn. Article 197 of the Personal Status Law provides that a solvent child — male or female — owes maintenance to insolvent parents; if the child's earnings exceed only his own needs and those of his wife and children, he shares what he has with his parents.
Article 198 provides that the maintenance of poor minors unable to earn is owed by solvent relatives who would inherit from them, in proportion to their inheritance shares; if the heir is insolvent, it falls on the next. Article 199 addresses preferring the evidence of solvency on dispute, and Article 200 imposes relatives' maintenance from the date of the claim.
Relatives' maintenance thus rests on three pillars: a qualifying kinship, the insolvency and incapacity of the entitled person, and the solvency of the payer.
Assessing whether these conditions are met and the amount of maintenance remains within the Sharia Court's competence on the facts of each case.
This is a general explanation based on Jordanian Personal Status Law and does not replace advice from a qualified lawyer in a specific dispute.
