Unfortunately for most people here in Dutch:
http://www.hogeraadvanadel.nl/ (High Council of Nobility, that deals
with anything noble).
The nobility in the Netherlands doesn't have a constitutional role
anymore since 1848. The only right they have is using their titel/
predicate. Also afterwards the monarch was allowed to raise,
incorporate or acknowledge Dutch nobility. Since 1994 there is a
separate law on nobility. Raising, incorporating or acknowledging are
still possible, but there are many restrictions. Incorporation can
only take place when people belong to legally acknowledged nobility of
another state with a nobility statute that is equal to the Dutch and
have asked for incorporation together with asking for Dutch
citizenship. Great Britain for example is a state that doesn't have an
equal nobility statute. Acknowledgement can only take place when
persons belong to a family that already was part of the Dutch nobility
before 1795.
The last time someone was raised in the peerage was in 1939, and in
1953 the government more or less abolished this possibility. Nowadays
only members of the royal house or former members within three months
after losing their position as member of the royal house can be raised
in the peerage. The last one was Princess Máxima of the Netherlands by
Royal Decree of 25 January 2002 (as of 2 February 2002, her wedding
day I suppose).
