1. Mere deletion of name of Father, from Society's membership is possible, via a Application + Death Certificate + Indemnity Bond. However, this will create a faulty Title of the property, for future transactions.
2. HOWEVER, the above will not delete the Title-Ownership rights of the deceased Father. Both the Son/s & the Mother, shall have equal Heirical & Title-Ownership rights over the 50% portion of the deceased father's property. There will remain perpetually.
3. TO transfer the 50% portion of the deceased father's property, in favor of Mother, you will need to execute a registered Family Settlement Deed amongst all the residual legal heirs in favor of Mother. ELSE file for "Letter of Administration" for the 50% portion of the deceased father's property, in favor of Mother.
