A case under the , particularly Section 138, is a cheque dishonour proceeding and not an immediate arrest warrant. Since you have received summons from the Court, it means the lender has filed a cheque bounce complaint and the Court has taken cognizance.
From your narration, an important issue arises: you state that you never knowingly issued any guarantee/security cheque and the loan repayment was through ECS. In many personal loan transactions, finance companies obtain: blank signed cheques, security cheques, or electronic mandates, during loan documentation. Sometimes borrowers do not remember signing them because they are included in the loan file at the time of disbursement or top-up.
Therefore, the first thing you must do is obtain: copy of the complaint, copy of the dishonoured cheque, bank return memo, and loan documents.
This will help determine: whose cheque was presented, whether it bears your signature, whether it was a security cheque, and whether the amount matches the alleged liability.
You should not ignore the summons. Since the matter is pending before the Bengaluru Court, you should engage a local advocate there immediately to: enter appearance, avoid coercive process, and seek exemption from personal appearance wherever possible.
Because you are presently residing in Chennai and also suffered a heart attack with angioplasty, your medical condition is relevant. Courts often permit: representation through counsel, or exemption from repeated personal appearance, especially in cheque bounce matters.
You should preserve: all medical records, angioplasty documents, discharge summary, and employment/business records showing financial hardship.
Please understand that inability to pay due to business loss is not by itself a complete legal defence in Section 138 proceedings if the cheque and liability are otherwise proved. However, many such cases are eventually resolved through: settlement, restructuring, instalment arrangement, or mediation.
You also mentioned that multiple loans/top-ups were consolidated or linked. Sometimes finance companies present old security cheques after default. Whether such use is legally sustainable depends on the exact facts and documentation.
At this stage, your immediate priorities should be:
engage a Bengaluru advocate,
obtain complete case documents,
ensure appearance through counsel,
avoid ex parte proceedings,
and explore settlement/restructuring options once your finances stabilize.
Do not avoid the Court process because continued absence may eventually lead to: bailable warrant, or later non-bailable warrant if summons are repeatedly ignored.
The good part is that cheque bounce cases are compoundable and settlement-friendly. Courts also generally encourage compromise in loan-related NI Act matters.
In conclusion, the summons does not mean immediate arrest or jail. Your first step should be proper legal appearance and obtaining the cheque/document details to verify how the Section 138 case has been filed despite ECS-based repayment arrangements. Your medical condition and financial hardship can also be appropriately placed before the Court while seeking reasonable accommodation and time.
