Section 49 Signing by mark by persons unable to write.

If any person whose signature is necessary under this Act is unable to write, it shall be lawful for him to adhibit a cross or other mark in the presence of the district registrar or two witnesses who shall also adhibit their signatures and designations, and such cross or mark shall be in all respects as binding and effectual as the signature of such person would have been if he had been capable of writing.
