What should I check before choosing a Luxembourg S.à r.l. name and activity?

The name must differ from every existing company, and its availability is checked with the Luxembourg Business Registers before the deed. The company must also hold any authorisation its activity needs, such as a business permit, before it starts trading. Insurance, savings and investment businesses cannot use the S.à r.l. form at all.
