Yes, a guarantor to a loan can sue the principal debtor if he defaults and the guarantor had to pay on his behalf. In fact, as per section 145 of the Contract Act, there is an implied promise to indemnify the surety. Also, as per section 140 of the said Act, the surety/guarantor steps into the shoes of the creditor and has every right against the principal debtor/ borrower once he i.e. the guarantor has satisfied the creditor's debt.
