Void vs voidable: the distinction that decides everything
Indian law splits invalid marriages into two categories, and which one you're in changes both the procedure and your rights.
The annulment cases we actually see in Chennai
In practice, annulment petitions here cluster around a handful of fact patterns:
Judicial separation: the option nobody explains
Judicial separation under Section 10 is a court decree that ends your obligation to live together, without ending the marriage. You remain legally married; you simply have the court's sanction to live apart.
People in Chennai choose it for real, practical reasons: religious conviction against divorce; family or community pressure that makes divorce unthinkable right now; wanting a cooling-off period with legal protection rather than a rushed decision; or needing maintenance and residence rights secured while keeping reconciliation genuinely possible.
What about the children?
This is the first question every parent asks, and the answer is reassuring. Section 16 of the Hindu Marriage Act protects the legitimacy of children born of void and voidable marriages. An annulment does not make your child illegitimate, and it does not remove their right to maintenance or to inherit from their parents. Custody and support are decided on the child's welfare, exactly as in any custody matter.
