Can I get a personal loan doing install payments after I received my discharge papers and if I can how long do I have to wait to get a personal loan?

You can get a personal loan any time after you file the bankruptcy.

The decision of whether to lend someone money belongs to each lender. There is nothing in bankruptcy law that says you must wait this long to borrow after a discharge or that requires a lender to issue credit to you.

Yes, but be careful.

Every lender has its own policies for how soon after a discharge they will make a new loan or grant credit. At a high-enough interest rate, you can find some entity to lend you the money you need fairly soon-but the interest rate will be sky-high. To fix your credit post-discharge, make it an absolute rule to pay every bill you receive, no matter how small, every month, without skipping any payments. In 24 months or so you will likely have improved your credit score enough to get a loan with standard interest rates.
