In the first year, you had oral partnership with another partner. The business went on the trust. Quite appreciable!
However, this very trust-based relationship has become obstacle in getting financial loan. Since you do not have any documents to prove that you had been partner, nothing can be done per se. Nevertheless, you had been drawing Rs 30,000/- per month. In that case, did you draw, Rs 360,000/- in the last year? If yes, then did you file Income Tax Return for the last Financial Year (FY)? If yes, then on the strength of the IT return, you may ask for the loan.
Of course, this may not work also. However, this is the only option that you have for to get the loan.
