Yes it’s your right to ask for maintenance under section 125 of crpc.
Oven if khula is complete or not you can ask for maintenance unless you have remarried.
You just have to file a petition for maintenance at your nearest court.
Yes you should not only ask for maintenance under 125 crpc but also file a domestic violence which will get you the relief to ask for a residence from your husband. Plus file for custody in family court for your child and ask for his maintenance. Meanwhile don’t give khula at all. Let your husband come to a settlement which he will have to because you would file so many cases against him. Don’t give khula now.
The situation in which the wife initiates divorce proceedings is known as KhulÕa. In the time of the Prophet (SAWS), the wife of Thabit b. Qais requested the Prophet for a divorce from her husband. The Prophet asked her to return the garden given to her at the time of marriage as dower (Mahr). She accepted this condition and the marriage was dissolved
In law it is said is said to signify an agreement between the spouses for dissolving a connubial union in lieu of compensation paid by the wife to her husband out of her property. Although consideration for Khula is essential, the actual release of the dower or delivery of property constituting the consideration is not a condition precedent for the validity of the khula. Once the husband gives his consent, it results in an irrevocable divorce. The husband has no power of cancelling the ‘khul’ on the ground that the consideration has not been paid. The consideration can be anything, usually it is mahr, the whole or part of it. But it may be any property though not illusory. In mubarat, the outstanding feature is that both the parties desire divorce. Thus, the proposal may emanate from either side. In mubarat both, the husband and the wife, are happy to get rid of each other . Among the Sunnis when the parties to marriage enter into a mubarat all mutual rights and obligations come to an end.
Reference: Khula is the right of a woman in Islam to seek a divorce or separation from her husband. More accurately, it is merely the right of a wife to seek a release from the marriage bond.
KhulaÕ means the separation of the wife in return for a payment; the husband takes the payment and lets his wife go, whether this payment is the mahr which he gave to her, or more or less than that.
The basic principle concerning this is the verse in which Allaah says (interpretation of the meaning):
ÒAnd it is not lawful for you (men) to take back (from your wives) any of your Mahr (bridal-money given by the husband to his wife at the time of marriage) which you have given them, except when both parties fear that they would be unable to keep the limits ordained by Allaah (e.g. to deal with each other on a fair basis). Then if you fear that they would not be able to keep the limits ordained by Allaah, then there is no sin on either of them if she gives back (the Mahr or a part of it) for her Al-KhulÔ (divorce)
A muslim wife cannot divorce her husband of her own accord. She can divorce the husband only when the husband has delegated such a right to her or under an agreement. Under an agreement the wife may divorce her husband either by Khula or Mubarat. Before 1939, a Muslim wife had no right to seek divorce except on the ground of false charges of adultery, insanity or impotency of the husband. But the Dissolution of Muslim Marriages Act 1939 lays down several other grounds on the basis of which a Muslim wife may get her divorce decree passed by the order of the court.
