Gestoría Mary Quiñonez

Gestoría Mary Quiñonez is an administrative services practice based in Castellón, Spain, offering online assistance throughout the country and in-person appointments at its Castellón office. Led by Mary Quiñonez, a registered administrative agent and economist, the practice supports individuals, self-employed professionals and businesses with clear, direct guidance through their administrative procedures.

Its services include immigration matters such as residency applications and renewals, family and study procedures, and Spanish nationality by residence. For traffic and vehicles, the practice assists with foreign driving-permit exchanges, ownership transfers, sale notifications, reports, duplicates and deregistrations. It also helps self-employed clients with starting an activity and ongoing fiscal and administrative management, with consultations and follow-up.

Additional areas of support include employment management and limited company formation. The process begins with a review of the client’s circumstances and available documentation, followed by an explanation of the information needed, the agreed service scope and next steps. Clients can make enquiries or request appointments by phone, WhatsApp or online; in-person service in Castellón is by appointment.
