In order to keep the family registers accurate and up-to-date, the Swiss authorities need to be informed about any changes in the civil status (birth, marriage, partnership, death and divorce) of Swiss citizens and dual nationals. When such changes occur, the persons concerned, or their nearest relatives, should send a complete and certified copy of the appropriate document/s (birth, death, marriage, partnership or divorce certificates) to the responsible Swiss representation.
Please note that these requirements are not set by the Swiss representations but by the respective cantonal offices in Switzerland. They make the final decisions whether the documents meet or do not meet the requirements.
Civil status changes (marital status, birth of children, death, name change, etc.) must be communicated to the Swiss authorities. Failure to provide accurate documentation may impede future administrative procedures with the Swiss authorities and even hinder the issuance of new identity documents, i.e. passports, etc.
