My elder sister passed away recently, and the family property is in her name. I got married later, but discovered that my wife is mentally unwell and was diagnosed with a condition. My family didn’t disclose this before the marriage. She’s currently receiving treatment. What are my options here? If I pursue an annulment, will she have any claim on my property?

You have grounds to pursue annulment on the basis of your wife’s undisclosed mental illness. However, an annulment does not automatically negate her claim to your sister’s property. Her rights would depend on the specific details of the property ownership and any relevant inheritance laws. You should consult with a lawyer to understand your specific options and potential outcomes.
