When purchasing a property, a missing GPA (General Power of Attorney) from a previous owner can cause significant issues, particularly with loan approvals. Even if the property has changed hands multiple times, the absence of this document can halt the registration process. It's advisable to check previous sale deeds for any mention of the GPA and obtain certified copies from the Sub-Registrar's office. You may also need to ask the current seller to report the GPA as missing to protect your interests.
