Is it necessary to submit all my original documents in law colleges at the of joining

Yes, original documents of prospective students has to be verified.

There is nothing wrong to submit the original certificates for verification.  But the problem you may encounter is that if you abandon the course in the middle of the academic course, then colleges may retain such certificates as security for payment of entire course fees.

For example, you secured admission, through a process and got a seat on the basis fo a competitive examination, the course is for 3 years, if you abandon it after one year, the college can not get admission during the second and third years.   As such the colleges must forego or sacrifice the fees, as they can not collect such fees from you.  In view of this several colleges are retaining such certificates as security and will return only if entire courses are paid to them.

However, these two processes are different.1.Candidates must submit certificates for verification which must be returned to candidates.  2.Even if the student abandoned the courses, it is illegal to retain such certificates and colleges can only recover the fees through other means. 

But contrary to UGC/AICTE/HRD directives several colleges (in specific Engineering colleges) that the recognition has to be canceled if they retain such original certificates, still, colleges are retaining certificates as security for recovery of fees for the rest of the course.

Yes, there is no such requirement. Extant norms only require that the Original Certificates are produced for verification. The College has no power or right to retain them.

However, it is an unfortunate situation many an institution are retaining then, purportedly, as security against the students leaving the course midstream, notwithstanding UGC instructions and Court Orders. It is only concerted action from the citizenry alone that can redeem the situation..  

No it is not mandatory to submit originals with all affiliated Colleges and deemed institutions under UGC act & rules made thereunder.
