Sale of flat

U take an indemnity from wife or u can ask them change the content of sale agreement n then issue NOC 

One more aspect  to be added to parikh's suggestion: apply for a succession certificate  and produce this to sell the said property. This will make it easier for the society and the buyer to complete the sale transaction.

if the share certificate is already transferred in the name of wife, then there will be no problem for society to issue NOC for sale.

if the share certificate is transferred without following due procedure, then the buyer will get the defective title. if soc has transferred share certificate according to will or probate of decesed husband or by succession certificate then there will be no problem.

Society has transferred share certificate after receiving  consent by the son (NOC to transfer the flat in the name of mother) , death certificate of the deceased member, Indemnity bond by wife and affidavit .

For Mr. Abhijeet Parikh : To change the content of sale agreement she want to make new registration in her name ? ..........

Sorry,read as  --- she required to make new sale deed in her name..
