“34A. Person claiming under document for sale of property also to sign document.—Subject to the provisions of this Act, no document for sale of property shall be registered under this Act, unless the person claiming under the document has also signed such document.”. [Vide Tamil Nadu Act 28 of 2000 with effect from 14.04.2001].

only the signature of the seller is mandatory and it is not required to have the signature or the thumb impression of the buyer.
