FAMILY settlement

No dear without making partition of the property it is not possible to get a registered sale deed.

Now you have two options; 

1st;         The share holders of the propert including your mother should relinquish their respective shares ( father's property ) towards you by way of a registered relinquishment deed properly valued and detailed with mention of payments received by them. Also get seperate detailed receipt fog the money you receive..

2nd;  Make the partition of the property by way of partition deed and let your brother to keep his share and other share holders can sell through a sale deed in your name. You brother should sign the partition deed and appear before registeriong authority.

Prefer option 2nd.

It is also recomanded that you purchase the other heirs share by way of registered sale deed .

No that is fine too do as i mentioned.

DOn't miss any details in the deed ,your mother should also relinquish her share otherwise your brother will demand share from her property afterwards

Just ensure that you get receipt for moiney you will pay from each share holders seperately as full and final payment for their selling/relinquishing of share .Mention that the possesion is already handed over to you .
