The procedure for getting married in Switzerland is clearly regulated by law. Nevertheless, many couples underestimate how early certain steps should be initiated, especially when there is an international connection. In essence, the process always follows the same pattern: first comes the marriage preparation (preparatory procedure), followed by the civil wedding ceremony at the civil registry office. Only with the civil ceremony is the marriage legally valid in Switzerland; a religious ceremony may take place in addition, but it does not replace the civil marriage.

1) The Process: From Application to Civil Ceremony

The process begins with the application for marriage preparation at the competent civil registry office (at the place of residence in Switzerland). There, it is checked whether both persons meet the legal requirements (e.g. identity, civil status, capacity to marry). Depending on the situation, the office requires different documents.

Once the dossier is complete, you will be invited to the marriage preparation. Both parties must appear in person at the civil registry office (exceptions are possible for persons residing abroad). Once the examination is completed, you will receive authorization to marry.

From this point on, one time window becomes particularly important: the civil ceremony must take place within a specific period. It is therefore advisable to plan the desired wedding date and the marriage preparation together from the beginning, especially in popular wedding months when appointments are quickly fully booked.

The ceremony itself takes place as part of a short procedure at the civil registry office and is accompanied by two adult witnesses who have legal capacity. After the marriage, you will receive the corresponding civil status documents (depending on the canton and purpose, e.g. marriage certificate or civil register extract).

2) Marriage Preparation: What You Should Clarify in Advance

Marriage preparation is more than just a formal step; it is the moment when you make the most important organizational and legal decisions. Particularly relevant here is the naming law.

In Switzerland, the general rule is: without a specific declaration, both spouses keep their previous names. If you wish to have a common family name, you may choose the single name (birth name) of one person as the shared family name. This declaration is made in connection with the marriage and should be discussed with the civil registry office in advance.

Especially for couples with an international connection, I also recommend preparing a clear document checklist early and ensuring that the documents meet the formal requirements of the authorities. In practice, delays arise less from “complex laws” and more from missing formalities, incomplete dossiers, or documents that are not accepted in Switzerland in their current form. If one person still lives abroad, the marriage application is submitted via the embassy together with the documents.

3) Civil Registry Office: Where and When Can You Marry?

As a general rule, the civil registry office at the place of residence is responsible; depending on cantonal practice, the ceremony may also take place at another location. The timing is crucial: the marriage can only take place once the preparation procedure has been completed. In addition, both persons must be legally present in Switzerland at the time of the marriage.

For foreign nationals, the migration law aspect must be considered early, especially if entry into Switzerland is planned specifically for the purpose of marriage.

Important for Couples with a Thailand Connection: Legalisation, Translations and Timing

In marriages involving Thailand, the procurement and preparation of documents is often the decisive time factor. In practice, Thai civil status documents (e.g. birth certificates, civil status confirmations, divorce documents) must be formally certified for use in Switzerland.

Since Thailand is not an Apostille country, recognition does not take place via a simplified Apostille procedure, but through multi-step certification and legalization requirements, possibly combined with certified translations. This is significantly more complex and requires planning.

Apractical advice: start early.

Depending on the individual case, obtaining the necessary certifications, translations and submission to the competent authorities can take considerable time, often several months until all documents are available in the correct form.

Plan for a Marriage Visa for Switzerland and plan a several month timeline

If the bride or groom is to enter Switzerland from Thailand for the purpose of marriage, a marriage visa (national visa D) is usually required in addition.

This visa process runs effectively in parallel with the marriage preparation: on the one hand, the civil status dossier is prepared, and on the other hand, entry and residence are assessed under migration law.

In practice, the timeline is again the key factor: processing a visa D can take several months, depending on the situation, documentation, and competent authority. In addition, the procedure is regulated at cantonal level, meaning processing times may vary from canton to canton.

Planning too tightly can lead to postponed appointments, expiring deadlines, or unnecessary administrative effort. It is therefore advisable to prepare the dossier early and consistently align the timeline, appointments and document preparation. Depending on the case and migration office, further questions may arise and additional information may be requested.

Conclusion

Getting married in Switzerland is well manageable if you understand the process and take the preparation phase seriously. For couples with a connection to Thailand, this is even more important: legalization and the marriage visa are the two aspects that require time and structured planning. Those who start early and prepare their documents carefully create the best foundation for a smooth marriage process.
