Is it permissible for the deceased partners to pay the remainder of the loan amount owed by them to their heirs, after the insurance company has paid the full loan?

If the insurance company pays the full loan, and the deceased was a partner in it, then the remaining partners must pay their shares of the debt to the insurance company. However, if the deceased was the sole borrower and distributed the amount among his partners, then the debt is owed by these partners to his heirs.
