Partnership deed - is franking ok instead of stamp paper?

Can partnership deed be executed on Franked ledger paper instead of non judicial stamp paper? Stamp papers are difficult to get!

Partenrs initial contribution is not quantified. Therefore can I do Rs.500/- franking on undated partnership document

on ledger paper?  Will it be acceptable for registering the partnership deed?

Thanks & kind regards,
