If you have discovered something after the order that changes the picture (a property you never knew about, income far higher than was declared, a valuation that was plainly wrong) the first question is not “can I reopen this”. It is “did this exist at the time, or did it happen afterwards”. The answer sends you down two completely different routes, and confusing them wastes a great deal of money.

Evidence that existed and was concealed points towards attacking the order itself. Evidence of something that happened later generally does not reopen a division of assets at all, though it may support a variation of maintenance. This page explains the distinction, the general principles governing fresh evidence, how concealment tends to surface, and the practical realities of trying to do something about it.

The distinction that decides everything

Family law treats a division of matrimonial assets as a clean break. Once the property has been transferred, the CPF moved and the accounts split, the court’s strong preference is that the parties are done with each other financially. Maintenance is different. It is forward-looking by nature and can be revisited.

So the two categories work like this.

It existed at the time and was not disclosed

An offshore account opened during the marriage. A shareholding transferred to a relative before the affidavits were filed. A second property held in a nominee’s name. A bonus already declared but not mentioned. In each case the fact was true when disclosure was given, and the other party’s obligation was to disclose it.

This points towards an application to set the order aside for material non-disclosure. The grounds, the burden and the risks are covered in setting aside a consent order, and the same logic applies to orders made after a contested hearing.

It happened afterwards

A promotion. A business that took off. An inheritance received after the order. A property that doubled in value. These are not concealment. They are the ordinary consequence of time passing, and the risk of them was accepted by both parties when the matter was concluded.

A post-order change of this kind will not usually reopen the asset division. It may well be relevant to maintenance, because a material change in either party’s means can justify revisiting a maintenance order. See what happens to maintenance when income changes.

The awkward middle case is something that existed at the time but was not yet crystallised: an unexercised option, a contingent bonus, a business sale under negotiation. Whether that should have been disclosed depends on how far advanced and how certain it was, and it is precisely the sort of question to take advice on rather than assume.

Fresh evidence on appeal: the general approach

Where the route is an appeal rather than a set-aside, the court does not simply accept new material because it is relevant. Appeals are reviews of a decision made on the evidence that was before the judge, and admitting fresh evidence is the exception.

The general approach, described here in outline rather than as a formula to apply yourself, asks three things:

  • Could the evidence have been obtained with reasonable diligence for the original hearing? If you could have found it by asking the right questions or making the right application at the time, the fact that you did not is your problem, not the other party’s.
  • Would it probably have an important influence on the result? Evidence that is merely interesting, or that shades a finding slightly, will not do. It has to be capable of changing the outcome.
  • Is it apparently credible? It need not be incontrovertible, but it must be capable of belief on its face.

The first limb is the one that defeats most applications, and it is worth sitting with. If the concealed asset would have shown up had you pressed a discovery request, issued interrogatories or asked for a bank statement you never asked for, you are likely to be met with the answer that reasonable diligence would have found it. How that plays out in a particular case depends on the facts and on how the courts have applied these principles. See appealing a divorce decision, and get advice on your own material rather than relying on a general description.

How concealment usually comes to light

People imagine a dramatic confession. In practice, concealment surfaces through mundane, semi-public routes:

  • A property transaction becoming visible. Property dealings leave a trail. A sale, a purchase or a mortgage entered into shortly after the order often reveals a source of funds that was never disclosed.
  • A business event. A company being sold, restructured, wound up or filing accounts can expose a shareholding, a director’s loan or a valuation that bears no relation to what was declared.
  • A change in lifestyle. A new car, a private school, a second home, frequent travel: spending that the disclosed income cannot support. On its own this proves nothing, but it is often what prompts someone to look properly.
  • People talking. A former employee, a business partner, a relative, or the other party themselves in an unguarded moment.
  • Documents surfacing later. Post arriving at the old address, a shared account or device still accessible, tax or CPF correspondence.

A note of caution: how you obtain evidence matters. Material gathered by accessing someone’s accounts or devices without authority can create problems of its own and may not help you as much as you expect. If you have found something, take advice before acting on it.

Act quickly

Time works against you in two ways.

First, there are formal deadlines. Appeals must be brought within short, strictly applied timeframes, and an extension is not something to count on. Applications to set aside are not subject to the same fixed clock but are expected to be made promptly, and unexplained delay is regularly fatal.

Second, positions harden. Assets get sold to third parties who know nothing of the dispute. Money is spent. People remarry. The longer you wait, the harder it becomes to give you a remedy even if you were right all along.

The correct response to a significant discovery is to see a lawyer immediately, with what you have, rather than to spend six months quietly building a file. Preserving your position comes first; the evidence-gathering can continue after.

What reopening actually costs

Reopening a concluded case is one of the more expensive things you can do in family law. You are running a contested application, on affidavit evidence, against a party who will dispute everything and who has already been through this once.

Realistically that means: legal fees for the application itself; possibly further discovery or tracing; possibly an expert to value a business or property; a hearing; and the risk of an appeal from whichever way it goes. Set against the fact that a failed application usually attracts an adverse costs order (see costs in divorce proceedings), the arithmetic only works where what was concealed is substantial.

The honest test is proportionality. If the hidden asset is worth many times the cost of pursuing it and the evidence is solid, the application may well be worth running. If it is a modest sum and the evidence is circumstantial, a candid lawyer will tell you so, and that advice is worth paying for even when the answer is no.

The lesson for anyone not yet settled

Every one of these applications exists because disclosure was inadequate the first time. The tools to prevent it are available before you settle, and they are far cheaper than anything described above.

Use them. Formal discovery and interrogatories let you demand specific documents and require answers to specific questions on oath, and an evasive answer to a precise question is itself useful. Where you suspect assets have been moved or spent to defeat your claim, the framework for dealing with dissipation of matrimonial assets lets you raise it while the court still has the case in front of it.

The pattern to avoid is the common one: accepting a thin set of disclosure because you want the divorce finished, and then spending years and considerably more money trying to undo the consequences. Press for the documents while the court is still seised of the matter. It is the one point at which asking is both easy and effective.
