What is a change of surname after marriage with a foreigner and what are the legal consequences
Ukrainian law allows choosing a surname after marriage: you can take your partner’s surname, choose a double surname, or keep your own. If your partner is a foreigner, additional nuances arise: properly executed marriage documents, legalized or apostilled documents, correct translation, and coordination with consular requirements. Without this, the surname change may be considered invalid abroad or cause issues when crossing borders, obtaining visas, or certificates.
Procedure for changing a surname after marriage with a foreigner: documents, translations, and legalization
The basic package includes:
- Marriage certificate issued by a competent authority (in the partner’s country or in Ukraine), legalized or apostilled if required by an international agreement.
- Translation of the marriage certificate and other (foreign) documents into Ukrainian — notarized translation.
- Identification documents: your Ukrainian passport (ID card or “booklet”), international passport, tax ID / taxpayer registration card.
- Other documents, if available: driver’s license, contracts / bank accounts, insurance policies, etc.
We assist in preparing the entire package, carrying out the necessary legalization, translation, and verifying the correctness of wording to avoid any “hidden pitfalls.”
Term for exchanging passports and other documents when changing a surname after marriage
The law stipulates a mandatory term for exchanging a Ukrainian citizen’s passport within one month after registration of marriage. Replacing the international passport is also recommended immediately (to avoid difficulties with travel or immigration procedures). Other documents — tax ID, driver’s license, property documents, bank cards — are changed as soon as possible; the faster, the lower the risks.
