Is it necessary to have a new marriage contract and mahr for a wife who was divorced and returned to the marital home after six months of staying at her family's house, knowing that the husband had previously tried to reconcile with her, but she refused?

If the divorce is not a completion of three (talaqs), the husband can reconcile with his wife before the expiry of her iddah (definition) (waiting period). The reconciliation is valid through explicit verbal declaration indicating it, or through an ambiguous verbal declaration coupled with the intention of reconciliation. If the reconciliation takes place before the expiry of the iddah, the wife returns to the husband's marital bond without the need for a new contract or dowry, and the reconciliation does not depend on the wife's or her family's consent. The iddah ends with purification from the third menstruation for a menstruating woman, or by childbirth for a pregnant woman, or by the passage of three months for a non-menstruating woman. However, if the iddah expires without reconciliation, the wife becomes irrevocably separated from the husband (ba’inah), and her return requires renewing the marriage contract with its pillars. If the divorce completes three (talaqs), the wife becomes irrevocably separated by a major irrevocable divorce (baynunah kubra) and is not lawful for her divorced husband until she marries another man willingly, and then he divorces her after consummation.
