The Swiss authorities online
If you want to get married abroad you must find out what documents you need before the wedding and notify the Swiss diplomatic mission after the wedding so that the documents can be sent to Switzerland.
Before you get married, make sure you:
You need to submit the necessary documents to the Swiss diplomatic mission in the relevant country. The Swiss diplomatic mission will then forward the documents to the appropriate Swiss authority. Please note that this procedure can take some time.
If one of the spouses is a foreign national, additional documents will be required. Contact the Swiss diplomatic mission in the relevant country in good time to find out what documents are required in your situation.
You must contact the register office for foreign nationals in your future canton of residence. It is responsible for the marriage recognition procedure.
