HI
1) A personal loan is an unsecured loan granted by a financial institution and hence banks can proceed to initiate civil suit against legal heirs..
2) The liability to pay an unsecured loan passes on to the family members upon the demise of the borrower.
3) However the liability of the legal heirs to repay the loan availed by the borrower is limited to the extent of properties(movable and immovable) vested on the legal heirs through Inheritance,
4) Insurance death claim are also now classified as an asset and the banks can make a claim on the same towards unpaid loans. However in such an instance, courts will ask the banks to take a hair cut on loan amount so as to ensure atleast 50% of insurance claim is available to legal heirs and balance 50% of insurance amount is towards settlement of loans.
5) You can claim the plea of non inheritance by submitting an affidavit to the effect that your wife did not have any assets (movable or immovable) to the court.
6) Courts in general expect legal heirs to come clean with disclosures on inheritance of assets from deceased family members. If the court is convinced that were indeed no assets whatsoever bequeathed by the deceased, the legal heirs will then be absolved of their liability by the court.
