To include family members in a Digital Nomad Visa application under Ley 14/2013, you must prove the legal link to the main applicant. Accepted documents include marriage certificates for spouses, birth certificates for children, and proof of domestic partnership (Pareja de Hecho) or financial dependency for adult children/ascendants. These documents must be issued by the Civil Registry or relevant authority in the country of origin.
All foreign documents must be legalized with the Hague Apostille (or via diplomatic channels for non-Hague countries) and translated into Spanish by a sworn translator (Traductor Jurado) authorized by the Spanish Ministry of Foreign Affairs (MAEC). For residency applications within Spain, these certificates should typically be issued within the last 3 to 6 months to ensure validity.
Common errors include submitting certificates without an apostille, providing simple translations instead of sworn ones, or using outdated documents. Note that if the main applicant registers as self-employed (Alta en RETA) and pays social security, family members may access the National Health System (SNS) as beneficiaries, meaning a private insurance policy might not be strictly necessary for all family members depending on the specific case and UGE-CE interpretation.
