The registered partnership provides almost the same rights and responsibilities as marriage and they both have similar steps.
If you plan to register your partnership, you first need to inform the gemeente (municipality) of the city of residence of one of the partners involved. This is called ondertrouw (notice of intent to marry). You need to do this at least two weeks before the intended date of the partnership registration which must take place within one year of submitting the notice. If the one-year period expires, then you need to resubmit another notice of intent to marry.
The documents needed may vary depending on nationality, previous marriages and residence status in the Netherlands. It is advisable to find out well in advance what documents you need to meet the requirements by contacting your local municipality. Required documents for both partners are similar to the documents requested for the marriage.
