Systems divide property on separation in two very different ways

The single biggest divergence in family law

People moving between countries, or reading advice written for a different one, run into this constantly. Broadly, two traditions exist for dealing with property when a marriage or registered partnership ends. One applies a property regime that governed the relationship from the outset and simply works out what it produces. The other gives a court a wide discretion to redistribute assets to achieve a fair result on the facts.

These are not variations on a theme. They ask different questions, they value different things, and an outcome that is routine in one system can be impossible in the other. Anyone assuming that a friend’s experience, or an article written elsewhere, describes their position is likely to be badly wrong.

How a property regime works

In regime-based systems, a couple has a matrimonial property regime from the moment of the marriage — sometimes chosen, more often the default supplied by law. It defines which assets are common and which remain separate, typically distinguishing what each party brought in and what they inherited from what was acquired during the relationship.

When the relationship ends, the exercise is largely one of classification and accounting: identify the assets, apply the regime, divide accordingly, and adjust for contributions made from one category to another. Predictability is the great advantage. The disadvantage is rigidity, since a regime applied mechanically can produce a result that leaves one party in serious difficulty, and systems have developed correction mechanisms of varying strength for exactly that reason.

How a discretionary system works

Discretionary systems start from a different place. Rather than asking which pot an asset falls into, they ask what division would be fair given the length of the relationship, the contributions of each party including non-financial ones, the needs of any children, the earning capacity of each and the standard of living established.

The strength of this approach is that it can respond to the particular family. The weakness is uncertainty, since two decision-makers may reasonably differ on the same facts, and that uncertainty makes negotiation harder and litigation more attractive. It also makes general statements about entitlement nearly useless, because the answer genuinely depends on a combination of facts that no article can weigh.

Agreements made before or during the relationship

Both traditions have to decide what weight to give an agreement the couple made themselves. In many regime-based systems, choosing or varying a regime by formal deed is ordinary practice and the agreement is straightforwardly effective, subject to formalities and to protections for the family home.

Discretionary systems have moved more cautiously, since an agreement cannot easily oust a jurisdiction to do what is fair. The common pattern is that such agreements are given real weight where both parties had independent advice, disclosed their finances honestly, entered into them without pressure and are not left in serious hardship by them. That is not the same as being binding, and describing them as binding — as marketing material often does — is misleading.

Pensions, housing and the assets that are hard to divide

Whatever the system, particular assets create recurring difficulty. Retirement provision is often the second largest asset and cannot simply be split like a bank balance; jurisdictions have developed sharing, offsetting and earmarking mechanisms with different consequences, and ignoring pensions is one of the most common and expensive mistakes made in do-it-yourself separations.

The family home raises the competing problems of realising value and housing the children, and business interests raise valuation and liquidity questions that usually need expert evidence. Debts have to be allocated as well as assets, and a division that looks equal on paper can be badly unequal once liabilities and future earning capacity are taken into account.

Cross-border complications, and where to ask

Where a couple has connections with more than one country, the question of which system applies can matter as much as the division itself, and different countries may reach different conclusions about it. This has produced a race to file in some regions and considerable litigation about jurisdiction, and international instruments coordinate only part of the picture.

Which regime or approach applies, what weight an agreement carries, how retirement provision is treated and what a court may do are all matters of local law that differ profoundly between countries and sometimes within one. Nothing here is advice about any particular relationship, and outcomes depend on facts and finances a general article cannot know. Time limits can apply to financial claims and to bringing them after a formal dissolution, so speak to a qualified family lawyer where you actually live before agreeing anything or transferring anything.
