There is a presumption of equal sharing of property acquired during a marriage or other relationship when it comes to an end. A fundamental issue is the value of the assets (and the liabilities) of the relationship.
If the former spouses or partners are unable to agree on this, the assets should be valued by experts so that agreement on their division can be reached as quickly as possible in order to avoid court proceedings. At the same time, debts of the relationship should be quantified and repaid or divided with the assets.
This is especially significant when trusts or companies are involved in matrimonial property or relationship property issues.
