My grandmother gifted me land when I was born. After my parents passed away, my brother sold a portion of it. Is this legally sound? What options do I have to address this situation?

Your brother’s sale of the gifted land may not be legally sound as you likely hold a rightful claim to it. You can explore legal options such as filing a suit for partition or seeking a declaration of your rightful ownership. Consulting a lawyer is recommended to understand your specific rights and options.
