Answer
Based on official Jordanian legal texts
The Jordanian Personal Status Law recognizes several kinds of maintenance according to the person entitled. The first is the wife's maintenance under Article 59 — what the husband owes his wife in food, clothing, housing, and medical care to the customary degree while the marriage subsists.
These include ʿidda maintenance under Articles 151 and 152, owed to a divorced woman throughout her ʿidda; child support under Article 187, owed by a father of means and including educational and medical maintenance under Articles 190 and 192; and relatives' maintenance under Article 197, which obliges a solvent child to maintain insolvent parents, along with the maintenance of poor minors owed by their heirs under Article 198.
A single rule unites these kinds in Article 64: maintenance is assessed by the payer's means, whether comfortable or constrained, and does not fall below the level of sufficiency. Each kind has its own conditions of entitlement and lapse.
Determining the applicable kind and its amount remains within the Sharia Court's competence according to the status of the entitled person and payer and 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.
