Your wife has no legal right to claim share in your self acquired property. She can only claim right to stay in matrimonial home. She may get permanent alimony while seeking divorce and maintenance of a fixed sum if she is not earning herself till she re-marries. The Hindu Marriage Act, 1955 also provide for settlement of property jointly owned by both parties which they were presented to them at the time of marriage.In the second property legally she has 50% share.
As per Section 125(l) (a) of the Code of Criminal Procedure, if any person having sufficient means neglects or refuses to maintain his wife, unable to maintain herself, a Magistrate of the first class may, upon proof of such neglect or refusal, order such person to make a monthly allowance for the maintenance of his wife at such monthly rate, as such Magistrate thinks fit, and to pay the same to such person as the Magistrate may from time to time direct. Here ‘wife’ includes a woman who has been divorced by, or has obtained a divorce from, her husband and has not remarried.
