Establishing who receives what and how much plays a major role if a couple separates or gets divorced. The rules depend on the matrimonial property regime. This changes when a registered partnership is converted into a marriage. In a registered partnership, unless otherwise agreed, each partner has their own assets and is liable for debts with their own assets. This regime corresponds to the separation of property in matrimonial law.
After the conversion of a registered partnership into a marriage or if a couple gets married, the community of acquisitions regime applies, unless stated otherwise in a property agreement or marriage contract.
