You still have to pay back the loan when you are in prison. You can refer to the following methods:

1. The loan is made by the husband and wife during the marriage relationship, and one spouse may be required to bear the repayment responsibility;

2. Fixed property can be executed, and deposits, bonds due or other real estate can be mortgaged.

It should be noted that even if the lender is imprisoned, the lending institution can bring a lawsuit in the court where he is imprisoned. At the same time, after the judgment takes effect, the lending institution may apply to the court for compulsory execution, and may execute all its personal property and the property jointly owned by the husband and wife.
