This is an important procedural question, and the honest answer is that once your spouse converts to another religion, a divorce case originally filed under the Hindu Marriage Act, 1955 can still proceed, but specifically on the ground of conversion itself, rather than continuing to treat the marriage purely under ordinary Hindu law principles as if nothing had changed. Section 13(1)(ii) of the Hindu Marriage Act specifically allows a Hindu spouse to seek divorce where the other party has ceased to be a Hindu by converting to another religion, meaning your existing legal framework accommodates this exact situation rather than requiring you to abandon your case and start over.

Importantly, since only one spouse needs to remain Hindu for the Hindu Marriage Act to continue applying to the marriage's dissolution, your divorce petition in Delhi can proceed under this Act using conversion as the specific ground, even though your spouse's personal religious status has changed. This is a deliberate legislative design ensuring that conversion by one party doesn't leave the other spouse without a clear legal remedy or force them into an entirely different, unfamiliar legal framework.

If your divorce case was already underway on other grounds — such as cruelty or desertion — before your spouse converted, you can typically amend your petition to include conversion as an additional or alternative ground, strengthening your case with what is often one of the more straightforward grounds to establish, since it generally requires less complex evidence than proving cruelty or similar fault-based grounds.

It's worth understanding that conversion by your spouse does not automatically resolve ancillary matters like maintenance, custody, or property settlement — these continue to be determined based on general principles of fairness and the child's welfare, regardless of either party's religious status, ensuring your rights and your children's interests remain protected throughout the proceedings.
