This is quite a complicated question. First of all, it depends on when you were married. If your marriage took place after 1 September 1992, then the 1978 Hague Convention on Matrimonial Property applies. The main rule in that convention is that parties can make a choice of law at the time of the marriage.
If they have not made a choice then the law of the common nationality of both will apply, or , if there is no common nationality, the law of the first common marital residence or, if there is no such first common marital residence, the law of the new common residence.
Furthermore, it is important to realise that the applicable law governing the matrimonial property may change if no choice of law is made.
It may change to Dutch law when you both acquire Dutch nationality or you have lived in the Netherlands for more than 10 years. This may result in your assets accumulated in the past not having to be divided but the assets accumulated in the period when Dutch law became applicable are suddenly common because they fall into the (Dutch) community of property and therefore have to be divided.
