Your mother cannot disown you from the property, especially if the property was owned by your father.

She had a chance of transferring her share to anyone during her lifetime, but you state that she is reported to have died intestate, hence as a legal heir to your parents you are entitled to inherit the property as a right.

You can take steps to obtain legal heirship certificate, then you can approach revenue department to get the revenue records in respect of the inherited property to your name on the basis of death certificate and legal heirship certificate in support of your claim.
