Hello dikhita,
Thw leaving certificate of lower class is always kept by the authority of the higher class for documentation purpose.
For example,like leaving of 10th is kept by college . Leaving of college is kept by university.
if you want to your 10th leaving certificate back for some time then you have to write a letter to the authority asking for certificate and also you have to mention the reason.
maybe they will give you the certificate back for sometime or definitely they can give you the xerox of your leaving certificate.
hope this may help you.
