My father wants to gift our house to his sister. Do we need a No Objection Certificate (NOC) for this? If so, what’s the process? Do I need signatures from specific authorities or just a signed format?

In India, a No Objection Certificate (NOC) from all legal heirs is not mandatory for gifting a property. However, a registered gift deed with the consent of all legal heirs is required to transfer ownership legally. You should consult a lawyer to understand the specific requirements and ensure the process is legally compliant.
