The lender can file both a mortgage suit and a cheque bounce case. In Indian law, civil remedies for recovery of debt and criminal remedies for dishonored cheques are independent, and a lender is entitled to pursue both simultaneously.
In Indian law, a cheque issued by a third party (including a spouse) toward the discharge of another person’s debt or liability is legally enforceable.
The cheque must have been presented to the bank and returned unpaid (bounced) due to insufficient funds, structural mismatch, or "payment stopped."
The lender must issue a legal demand notice within 30 days of receiving the bank memo.
The borrower must fail to pay within 15 days of receiving the lender's notice.
A civil mortgage suit and a criminal complaint under Section 138 are legally distinct. The Supreme Court of India has held that civil recovery actions do not bar criminal prosecution for cheque bouncing.
If the borrower provided blank "security cheques" at the time of initial loan disbursement, the lender can legally fill in the balance amount declared due and present them, provided the debt is actual and subsisting.
