Sir, I have an under construction property in gaziabad- Owner my wife and I am the co-owner, possession for which will be given in September. My parents live in Agra and I with my wife live and work in Hyderabad. I am not a resident of Hyderabad, and we live here in rented accomodation. However, I have Voter's ID and Adhar card showing my address in Hyderabad, my wife has Adhar card and a bank account in hyderabad - on hyderabad address. For some reasons I may not be able to travel to Gaziabad for registration formalities and I wish to give a SPA to my father who then shall be able to take care of all the formalities related to property registration in Gaziabad. My builder has asked my to get the SPA registered for my father to be able to carry out all these formalities. My query: Can I call my father to Hyderabad and have the SPA registered here itself (I understand that all the parties must be present for this purpose) Please let me know if any more information is required
