Property of grandparent

Your father is a co-sharer to your Grandfather property after his intestate death, and your uncle is playing smart and getting signatures of legal heirs of deceased father.  It is upto you to decide further on seeking share of your father.  Your grandfather's intestated property must be shared by his wife and children equally as per law.

By virtue of will deed your mother wil get the share from the property equally as that of your Uncle. Now if your Uncle want to make the documents to be signed by all of you what is the harm if he is ready to distribute the sale amount .

If you are willingly allowing the sale of property then sign all of you what is the problem ;

However the amount of sale shall be divided into two parts one for your Uncle and one for your mother  having will deed . Then your mother has choice to distribute as she desieres.

Just be careful,don't sign anything until the sale amount is not distributed. Receive the sale amount in cash first and balance  by amount by  cheques and promissory notes . If you did not received the amount then while appearing for registering authority you can refuse and clearaly make a statement that you did not received the money. Don't let sale proceed until the shares cleared. 

Secondly read each document and don't sign any of you any kind of bland stamp paper,or power of attorney or any document that is other than sale dcoument,

if you need to hire an advocate for that then do hire for protection.

Otherwise your next quieries would be in lots and that wont have any solutions at all.

From the facts stated, the deed need to be signed only by your mother. However, before execution of the deed, settle as to what as to the sharing of sale proceedings.

Because your father has bequeathed all his property in the name of mother, your father's entire share should go to your mother.  But, whether your father can write a will of entire ancestral property to your mother alone is doubtful.  Always trust local advocate and before signing seek for the draft copy  from your uncle for legal advice.

Facts posted are insufficient to infer that the property has been ancestral.
