In order to obtain a dissolution of your marriage or civil union in New Zealand the parties must be separated for a period of two years or more and one of the parties must be domiciled in New Zealand.
A dissolution is obtained by application to the Family Court either by one party on their own or by both parties together.
If you have not been separated for the two years required to make an application then there may be other things that we can assist you with in the meantime such as division of relationship property and care arrangements for your children.
