My father passed away recently, leaving behind a flat in his name. I am his sole heir and have a legal heir certificate from Chennai Corporation. My mother is still alive. Can I sell the flat and receive the proceeds? What legal hurdles might I face in selling it?

As the sole heir with a legal heir certificate, you can sell the flat. However, you might face legal hurdles if your mother objects to the sale, as she has a right to a share in the property as a surviving spouse. You may need to obtain her consent or seek a court order to proceed with the sale.
