I lost my original relieving letter only have xerox copy - what can I do?

Hi, i am mechanical design engineer. I lost my original relieving relieving letter in xerox shop. I have xerox copy of relieving and scanned copy of relieving too and also i am having original experience letter. Now help me to how to get relieving letter?

Original relieving letter can be obtained from old employer only.
Write to them and ask for a fresh letter explaining that original is lost.
If you had a good exit, the company will generally oblige.

Hi,
Please approach your previous company show them the xerox copy of the relieving letter and original experience letter and request them to issue a duplicate relieving letter.
As your clearance is done, HR should not have any problems is issuing this duplicate letter.
Thank you,

is this any compulsory requirement of original relieving letter to a newly joining company? or else it is sufficient to xerox copy of relieving letter and original copy experience letter.
