How is the ex-wife's maintenance calculated after divorce, and is the duration of the marriage a condition for its calculation, knowing that the husband did not provide for his wife during the 'iddah period and did not pay the deferred mahr, and that the wife spent her 'iddah in her family's home because the husband changed the lock of the apartment door?

A divorced woman is entitled to financial support (nafaqa) from her husband if the divorce is revocable (talaq (definition) raj'i), or if she is pregnant. However, if the divorce is irrevocable (talaq ba'in), she is not entitled to financial support unless she is pregnant. There is no fixed limit for estimating the financial support; it depends on custom and the husband's financial capacity. It is advisable to refer to the Sharia (definition) courts to adjudicate such matters.
