My uncles and aunts sent a legal notice after my father passed away. They’re claiming that the land my father owned should be part of their father’s property now.

Under Indian law, your father’s property would be inherited by his legal heirs, including you, according to the law of intestate succession. Your uncles and aunts may have a claim if your father had made a will, but their claim based on their father’s property is likely not valid. It’s best to consult a lawyer to understand your rights and the specific legal implications of the notice.
