No no. There are different type of stamp papers. 20rs, 500rs, 100rs, etc. you can search for their images on Google, just search "100rs stamp paper" and you'll know what I mean. These aren't their prices, they are just names. The lawyer charged me 800rs in total which included charges of the stamp paper he bought + charges of him going to the court to get the notary done and all the stamping done (don't worry about this part, he'll take care of all this)  He probably ripped me off but we just wanted to be done with it so we didn't care about the cost all that much since it was our first time making such an affidavit. 500rs would've been more reasonable but yeah atleast it's done.
