Title transfer/registration

If you have the legal heir certificates  then you can sell the property as Legal Heirs. It is NOT MANDATORY to have the Mutation and Registered Deed in the name of Seller.

Dear Sir, Thank you for the reply. But one other doubt, since the living person is the grand daughter to the land owner does having Legal Heir certificate give her the right to register that land on our name?

The posting suggests deeper issues. Please post complete facts.

This is not a simple issue as the document/revenue records stand in the name of the grandmother, and the physical possession is not known.  Having a name in the revenue may be only useful to establish possession.   Unless the property is divided into metes and bounds showing the extent and boundaries for the property standing in the name of Grandmother, it's not lawful to sell away the land.

However delivery of possession is most important, and there are lakhs of purchasers who wish to grab the lawfully or unlawfully at a throwaway price, even when the property is in dispute.  Everyone is aware that litigation takes decades to get settled.

Dear Sir, Following are the complete details of the property. It is a joint property(ancestral) between us and our cousins. 
We haven't done the partition yet. No third person is in possession of it or none of us(we or our cousins) occupied it. 
And we are clear with all the actual bounderies of the joint property since we have a big wall around the entire land. 
So now we want to purchase their share of land too instead of partitioning the exisitng proerty. 
But as I mentioned in my first post one of share holders land is on their grand mother name and her grand daughter is ok to sell her share of land to us. 
Now for us to get that piece of land registerd on our name what does our cousin required to do or what all documents are necessary for her to get the right 
to register that land to us.

Contact a local advocate for precise guidance.

How is that the property is ancestral? What do you mean by ancestral?

And post precise and succinct  facts, not subjective opinions.
