Different signatures on varioud id documents

Miss jayanti devi, student, the practice of putting  diffirent signatures on diffirent documents is one of the serious lapse at the part of siigning person.This also creates  so many legal complications. For example, if a person have opened a bank account puting his specimen signature and thereafter he issues a cheque to a party putting a diffirent signature on the same resulting in non-payment of cash after due verification his signature. So this can be a problem to him facing cheque bounch case in the court of law.

Moreover what is intention behind this for putting a diffirent signatures on diffirent documents.

I hope this will be helpful for you.

Thanks

I am not saying that a person will use the wrong specimen in the applicable documents. He will obviously remember which signature he is using in which document.

There is no wrong intention other than preventing someone from copying it.

My only question is -is it legally PERMISSIBLE ?

Ex; Can i have different specimen signatures on Pan and Aadhar? It it legally allowed ?
