The contents of the will have to be honoured. How and why should you give the authorities NOC when the other shareholders are not ready. You should file for probate of the will and letters of administration in the court wherein the court shall grant you the rightful owner.

In case you want you go the other way, a relinquishment deed or an noc may be filed with the authorities. They will mutate the property in your name. Then you may sell it.

Once you have a will they cannot deny mutation. That is against the law. You should approach the courts.

1’)Registered Gift deed can be executed by other legal heirs in favour of your father 

2) in alternative apply for probate of will 

3) other legal heirs can execute consent affidavit to relinquish their share in property 

Hello,

1.  A relinquishment Deed by all the legal heirs in favour of any one particular  heir would be appropriate under circumstances. A Gist Deed in the similar fashion will have the same effect and cost.
2. Alternately, you can get the Will probated in Court and the Probated Will shall be binding on all the disgruntled heirs as well as the Land & Development office, which would have no other way but to comply by the stipulations in the Will.

All deeds mentioned by require stamp duty of 3 per cent if transferred to female and 7 per cent if transferred to male. Even gift deed and release deed require payment  of stamp duty. The best and cheapest option is NOC  from all legal heirs.  

If you people have decided to settle the issues amicably and sell the proeprty as per your mutually agreed conditions, then you can obtain the NOC from the legal heirs of yor deceased grandmother and get the property mutated to your name.

After that you people can sell the proeprty and divide the sale consideration amount among yourselves as per the conditions of agreement. 

Dear Sir/Ma'am,

1) You have option to get the will probated by a court of law and claim whole of the property as per the wishes of your late grand mother.

 2) If you have decided amicably to enter settlement with your family to equally divide the shares when property is sold, the best way will be to get NOC from all the heirs and get the property mutated in your name. Later sell the property and divide proceeds as per the settlement agreement made with the other family members.

Thank you

- Further, if other legal heirs are ready for releasing their respective rights in your favour , then they can execute a Relinquiesent deed in your favour. 

- Otherwise, jointly can sell the property as well.
