Delaware constitution
Article III
Section 10

The Governor shall appoint, by and with the consent of a majority of all the members elected to the Senate, a Secretary of State, who shall hold office during the pleasure of the Governor. He or she shall keep a fair register of all the official acts and proceedings of the Governor, and shall, when required by either House of the General Assembly lay the same, and all papers, minutes and vouchers, relative thereto, before such House, and shall perform such other duties as shall be enjoined upon him or her by law. He or she shall have a compensation for his or her service to be fixed by law. The Secretary of State shall become a bona fide resident of the State within six months after his or her appointment; provided, however, that upon good cause shown, the Governor may grant an additional extension of six months. After becoming a resident of the State, the Secretary shall continuously be a resident of the State as long as he or she retains office. Failure to obtain or retain such residency shall be an automatic resignation from office.
