If you've lost original property documents such as sale agreements, affidavits, or powers of attorney, it's crucial to understand that a notary or power of attorney alone doesn't constitute absolute title. It's recommended to consult a local lawyer with all available documents, including copies. The lawyer can advise on the validity of your purchase. You may need to contact the original seller, Mr. Rafique, to potentially execute and register a fresh sale deed in your favour.
