Do not want anything from mothers property

If the property is being transferred by the order of a gift deed, then you can decline it, since it needs your signature.

However, if she has passed away without any testament, then you would be getting full/part of the property. 

How many legal heirs does your mother have? 

Just need to register a relinquishment dee.

A relinquishment deed is a legal document that transfers the ownership of a property from one person to another. It is commonly used in cases where a co-owner or a legal heir wishes to transfer their share of the property to another co-owner or legal heir.

1. how may other heirs?
2. is mother alive?

Is your mother dead or alive? If your mother is alive and you are not interested in her property, just keep quiet. If your mother is dead it is for others who want her property to worry about. If they come to you, offer them to give a relinquishment deed. It is their botheration to do what all necessary to get a relinquishment deed from you. Just for your information there are High Court judgments saying that there is no stamp duty (except a nominal one) for a relinquishment deed. If at all there is stamp duty let others pay.
