EX-21: residence document for non-EU family members of UK nationals in Spain

EX-21 («Solicitud Documento de residencia Artículo 50 TUE para nacionales de terceros países familiares de nacionales del Reino Unido») is the official form a non-EU family member of a UK national uses to apply for the residence document under the UK Withdrawal Agreement (Article 18.4). The same form covers permanent residence, changes of details and deregistration. It is in Spanish, three pages: two to fill in and one with instructions.

EX forms are only accepted in the official model: FoxDocs writes your data into the fields of the official PDF without changing its layout.

• the spouse, registered or duly proven partner, children, dependent parents and other family members of a UK national who are third-country nationals covered by the Withdrawal Agreement;
• if you already hold an EU family member residence card and have lived in Spain for less than 5 years, the official guide says EX-21 is not needed: the card is exchanged directly at the police with form EX-23;
• EX-21 is filed at the Oficina de Extranjería of the province where you live or will live: in person or through a representative with an appointment (cita previa), or electronically;
• if you started living in Spain after the end of the transition period (31 December 2020), the deadline is three months from arrival; later applications are accepted but a fine may be imposed;
• the Oficina de Extranjería decides within three months; filing there is free, the fee (model 790, code 012) is paid for the card itself;
• once approved, within one month you apply in person at the police with form EX-23, give fingerprints and receive the TIE card.

• section 1 — applicant: passport, NIE (if any), surnames, given name, sex, date of birth (dd/mm/yyyy), place and country of birth, nationality, marital status, parents’ names, address in Spain, phone and e-mail, legal representative;
• section 2 — UK national: passport and NIE, surnames, given name, relationship to the applicant, nationality and address in Spain;
• section 3 — representative filing the application, section 4 — address for notifications, consent to DEHú electronic notifications;
• section 5 — date residence in Spain began, type of application (temporary, permanent, change, renewal, deregistration) and ground;
• declaration of accuracy, place and date, signatures of the UK national and the applicant, addressee office.

• form EX-21, original and copy, filled in capital letters and signed;
• a valid passport (if expired — a copy and the renewal application);
• proof of the family link, marriage or partnership;
• the certificado de registro or residence document of the UK national you join or live with;
• where the ground requires it — proof that you are dependent on the UK national;
• one photo meeting the Spanish ID card (DNI) photo requirements;
• proof that you lived in Spain before 31 December 2020, if that is your case: any legally valid evidence is accepted.

1. Tell the chat, in any language, who you are, how you are related to the UK national and since when you live in Spain.
2. The assistant fills the boxes in capitals, splits dates into dd/mm/yyyy and the NIE into its cells, and ticks the application type and ground.
3. Download the PDF, check and print it; you and the UK national sign it — then file it with a copy.
