Section 323 - Further relief1. A person may, at any time during his period of military service or within six months thereafter, apply to a court for relief in respect of any obligation or liability incurred by such person prior to his period of military service or in respect of any tax or assessment whether falling due prior to or during his period of military service. The court, after appropriate notice and hearing, unless in its opinion the ability of the applicant to comply with the terms of such obligation or liability or to pay such tax or assessment has not been materially affected by reason of his military service, may grant the following relief: (a) In the case of an obligation payable under its terms in installments under a contract for the purchase of real estate, or secured by a mortgage or other instrument in the nature of a mortgage upon real estate, a stay of the enforcement of such obligation during the applicant's period of military service and, from the date of termination of such period of military service or from the date of application if made after such service, for a period equal to the period of the remaining life of the installment contract or other instrument plus a period of time equal to the period of military service of the applicant, or any part of such combined period, subject to payment of the balance of principal and accumulated interest due and unpaid at the date of termination of the period of military service or from the date of application, as the case may be, in equal installments during such combined period at such rate of interest on the unpaid balance as is prescribed in such contract, or other instrument evidencing the obligation, for installments paid when due, and subject to such other terms as may be just.(b) In the case of any other obligation, liability, tax, or assessment, a stay of the enforcement thereof during the applicant's period of military service and, from the date of termination of such period of military service or from the date of application if made after such service, for a period of time equal to the period of military service of the applicant or any part of such period, subject to payment of the balance of principal and accumulated interest due and unpaid at the date of the termination of such period of military service or the date of application, as the case may be, in equal periodic installments during such extended period at such rate of interest as may be prescribed for such obligation, liability, tax, or assessment, if paid when due, and subject to such other terms as may be just.2. When any court has granted a stay as provided in this section no fine or penalty shall accrue during the period the terms and conditions of such stay are complied with by reason of failure to comply with the terms or conditions of the obligation, liability, tax, or assessment in respect of which such stay was granted.
