You may have to provide the Dutch Immigration and Naturalisation Service (IND) or the Dutch municipal authorities with documents such as marriage or birth certificates.
Please note that any foreign documents that you present to the Dutch government need to be translated to Dutch, English, French or German by a sworn translator and it may be necessary to attach an apostille stap or to have the document legalised in some other way.
Information regarding legislation can be on the website of the Dutch Ministry of Foreign Affairs website.
