Answer
Based on official Jordanian legal texts
ʿIdda maintenance under Jordanian law is an established right of a woman observing the ʿidda after divorce or annulment. Article 151 provides that the husband owes maintenance to the woman in her ʿidda, and Article 152 states that this maintenance continues for the duration of the ʿidda and may extend with it, subject to the statutory limit of one year.
ʿIdda maintenance covers what maintenance generally covers under Article 59 — food, clothing, housing, and medical care — to the customary degree and according to the husband's means, whether comfortable or constrained. Article 154 confirms the woman's right to lawful housing throughout her ʿidda.
The duration of this maintenance tracks the ʿidda period set out in Articles 145 and 147: three menstrual cycles or three months for a non-pregnant woman, and until childbirth for a pregnant woman. ʿIdda maintenance ends automatically when the ʿidda ends; if the husband takes his wife back in revocable talaq, general spousal maintenance resumes.
A wife in nushūz may be denied maintenance, and ʿidda maintenance is independent of the deferred dowry and of child support, which remains an obligation on the father.
This is a general explanation based on Jordanian Personal Status Law and does not replace advice from a qualified lawyer in a specific dispute.
