BPC §7558.5: Except as otherwise provided in this article, an expired license or branch office certificate may be renewed at any time within three years after its expiration on filing of application for renewal on

Except as otherwise provided in this article, an expired license or branch office certificate may be renewed at any time within three years after its expiration on filing of application for renewal on a form prescribed by the director, and payment of the renewal fee in effect on the last preceding regular renewal date. If the license or certificate is renewed more than 30 days after its expiration, the licensee, as a condition precedent to renewal, shall also pay the delinquency fee prescribed in this chapter. Renewal under this section shall be effective on the date on which the application is filed, on the date on which the renewal fee is paid, or on the date on which the delinquency fee, if any, is paid, whichever last occurs. If so renewed, the license or certificate shall continue in effect through the date provided in Section 7558 which next occurs after the effective date of the renewal, when it shall expire if it is not again renewed. Renewal of a license or certificate shall not prohibit the bringing of disciplinary proceedings for an act committed before the effective date of the renewal.
