Affidavit

Engage a local lawyer to help you.

Dear Abhaykumar,

                               Please contact a lawyer immediately. infact engage a lawyer asap since you have signed on a blank Stamp paper. never should you sign or give a thumb imprint on a blank piece of paper/documetns/anything at all!!

for further help (no fees charged for initial consultancy) email me at arpit.m.lalan@gmail.com

you should consult local lawyer in this matter

Many thing has to be taken into consideration you told that the stamp paper was purchased for rent purpose.

What is written on the back side of the stamp paper (The Purpose for which the stamp paper is taken, who has bought the paper, whose signature etc.....their are many things which has to be considered before giving any opinion. so it is better you consult a lawyer

Nothing can be advised without seeing the document.

Although the stamp papers are purchased by a particular person and his/her compelete details are mentioned  by the stamp vendor, who is supposed to keep a record as well, yet, these finer details (who purchased the paper/when purchased/what for it has been purchased etc etc.) are to be considered for demolition of evidence set up by the person using the stamp paper in his/her favour, otherwise these details (generally) does not carry weightage..
