I have a B permit, and my girlfriend has a L. We want to get married in Switzerland (not wedding, not foreign marriage recognition), just to register marriage here in Lausanne.

Is there an official website which lists all the required documents for official marriage for non-EU residents? I don't find it. Anyone had experience before?

Here are some websites that might help (quick Google search):
