Employer asking for Form16

Dear Mahesh,

Many candidates appearing for interviews often lie about their last drawn salary in expectation for higher salaries, hence as a check to discourage candidates from such malpractises some prospective employees ask the candidates to prodduce such things. I think there is no need to worry in case of a genuine candidate to produce the credentials.

Dear Mr.Mahesh,

                            if you ask " is it necessary?"  the answer is "no".  there is no legality involved  in this. My opinion is insteasd of asking Form-16, they can do pre-employment verification which will be proffesional in approach. 

what is Form 16.
