signed on blank sheet?

Is he worried or you j/k

I don't understand how it could have helped then either. A paper signed document is not valid, a stamp paper signature is. Also it should have witness signatures (notary etc). One can always back off saying that he was either coerced or it wasn't his signature at all.

 

Nandshyam is right. I had to give some papers to my dad before coming to the US for bank purposes. I had to write a letter, saying that I would be out of the country etc. It was on stamp paper with both mine and dad's signature, witnessed and signed by notary. Only then it is considered valid. Signature on blank paper is quite worthless for any legal purpose. So don't worry take care.

 

I think it is really sad that your husband thinks that his parents would cheat him just because he had some arguments with them. UNLESS he has valid reasons to believe that his parents have NO morals or ethics, it is really wrong on his part to suspect them and speculate that they could misuse his signatures for evil purposes.

If they have previously proven to lack ethics, then the ideal thing to do is to issue a gazette notification in a few leading newspapers, stating that your husband had issues blank signatures to certain persons and that any documents that are drawn up using those papers are null and void. This should cover his butt, but will ruin his relationship with his parents for good.
