In the ancillary matters, both spouses must give full and frank disclosure of their financial position. Most people who lose money at this stage do not lose it by being outargued. They lose it by getting the disclosure wrong, by omitting something, understating something, or treating a sworn affidavit as an opening bid, and then spending the rest of the case defending their own credibility instead of their position.

The mistakes below are the ones that recur. Each is easy to make, each is easier to catch than people expect, and each has a fix that costs nothing if you apply it before you sign.

1. Omitting an asset you think is “yours”

The most common error, and the most damaging. A flat bought before the marriage, an inheritance from a parent, a bonus saved in a sole account, a property overseas. It feels separate, so it never makes it onto the form.

Whether an asset forms part of the matrimonial pool is a legal question turning on how it was acquired and how it was used during the marriage. Pre-marriage assets and gifts or inheritances can fall outside the pool in some circumstances and inside it in others, particularly where they were used for the family or improved by the other spouse’s contributions, as explained in the guide to gifts and inheritance in a divorce. That is an argument you are entitled to run, and often to win.

The fix: disclose it, then argue about it. Put the asset in the schedule with a note on why you say it should be excluded. You keep the argument and you keep your credibility. Omit it and you lose both, because when it surfaces, the point is no longer whether it was matrimonial, but why you hid it. Assets abroad are no exception; see overseas assets in a divorce.

2. Understating your income

People report their basic monthly salary and stop there. The actual figure the court is interested in is everything that comes in.

Commonly left out:

  • Annual bonuses, performance bonuses and commissions.
  • Allowances: transport, housing, entertainment, overseas postings.
  • Director’s fees and dividends from a company you have an interest in.
  • Rental income from an investment property.
  • Freelance, consultancy or side-business income.
  • Employer CPF contributions and other benefits with a real value.

Business owners face a version of this that is harder to manage, because personal and company finances intertwine and a modest declared salary may sit alongside substantial drawings; this is covered in divorce for business owners.

The fix: disclose gross income from every source over a multi-year period, and let the tax returns and bank credits corroborate it. A variable income is a legitimate argument for a flexible maintenance structure. A concealed one is just a lie that a set of bank statements will expose.

3. Forgetting the assets that do not look like assets

Bank balances and property come to mind immediately. These do not, and they are frequently the largest items after the home:

  • CPF monies. Ordinary, Special and Medisave balances are part of the picture, and the court can make orders affecting them subject to CPF rules; see CPF in a divorce.
  • Insurance surrender values. A whole life or endowment policy has a cash value now, not just on maturity. The guide to insurance and divorce covers how policies are treated.
  • Employment equity. Share options, restricted stock units and deferred awards, including unvested ones; see stock options in a divorce.
  • Cryptocurrency and digital assets. Holdings on exchanges or in private wallets are disclosable like anything else, and are traceable more often than people assume; see cryptocurrency in a divorce.
  • Club memberships, vehicles, jewellery and collectibles with meaningful value.

The fix: build the schedule from documents, not memory. Pull every statement, policy summary, CPF statement and equity award letter before you start writing.

4. Moving money before you disclose

Transferring savings to a sibling. A large cash withdrawal “for expenses”. Repaying a family loan nobody mentioned before. Closing an account weeks before the affidavit is due.

Bank records make this obvious. Statements are chronological, the divorce timeline is documented, and a transfer that has no counterpart in years of ordinary spending stands out on a single page. Where sums have gone without proper explanation, the court can add the value back into the pool and treat the moving spouse as having already received it; the principle is set out in dissipation of matrimonial assets.

The fix: from the moment the marriage is in trouble, make no unusual financial moves. Keep spending in its normal pattern, and where a genuinely necessary large payment has to be made, document the reason at the time. A contemporaneous explanation is worth far more than a reconstructed one.

5. Numbers that do not add up

Inflating your expenses

The mirror image of understating income, and just as visible. Monthly expenses are padded so that the apparent surplus available for maintenance shrinks to nothing.

It fails for a simple arithmetic reason. If your stated expenses exceed your stated income month after month, you must be funding the gap somehow: from savings that should therefore appear in your disclosure, from borrowing that should be documented, or from income you have not declared. Every version of the answer damages you.

The fix: take the actual figures from twelve months of statements. Separate genuinely fixed costs from discretionary ones, and be ready to explain anything unusual. A realistic expense schedule that reconciles to your accounts is persuasive; an aspirational one invites the court to work out the real number itself.

Inconsistency across your own documents

The affidavit says one figure. The tax returns say another. The bank statements say a third. The mortgage application you made last year said something else entirely.

Opposing lawyers look for exactly this, because it is the cheapest way to undermine a witness. You do not need to be caught lying about anything material: three unexplained inconsistencies are enough to make a judge read your whole affidavit with suspicion, and once that happens, the benefit of the doubt goes to the other side on every contested point.

The fix: before signing, lay your affidavit alongside your tax documents, payslips, CPF statements and bank statements, and reconcile them line by line. Where a genuine discrepancy exists, such as a one-off gain, a repaid loan, or a change of employer, explain it in the affidavit rather than waiting to be asked.

6. Being evasive in discovery

After affidavits are exchanged, each side can request further documents and pose written questions through discovery and interrogatories. Some people treat this as an attack to be resisted: they answer narrowly, produce partial statements, ignore requests, or respond so late that a hearing is needed.

The court’s response is the adverse inference. Where a party has not made full disclosure, the court can proceed on the footing that undisclosed assets exist, and reflect that in the share awarded. It does not need to identify the hidden asset or value it precisely. Practically, evasion can cost more than the concealed asset was worth, and it usually comes with costs orders on top. The process itself is explained in discovery and interrogatories in a divorce.

The fix: comply properly and on time. Where a request really is disproportionate or irrelevant, object through your lawyer with reasons; that is a legitimate position. Silence and partial production are not.

7. Treating the affidavit as a negotiating document

The underlying error behind most of the others. People approach the affidavit of assets and means the way they would approach an opening offer: understate what you have, overstate what you need, and expect to meet in the middle.

It is not an offer. It is sworn evidence, filed in court, which you are confirming is true. A false affidavit can lead to adverse findings on credibility, cost consequences, an unfavourable division, and potential proceedings for contempt or for making a false statement. The document’s purpose and structure are set out in the guide to the affidavit of assets and means, and it is worth reading before you draft rather than after.

The fix: state the truth, and make your arguments as arguments. There is ample room for advocacy in how assets should be characterised, what weight indirect contributions carry, and what a reasonable standard of living looks like; the whole framework for dividing matrimonial assets depends on it. What there is no room for is a wrong number.

What good disclosure actually looks like

  1. Documents first, schedule second. Gather statements, policies, CPF records, payslips and tax documents, then build the affidavit from them.
  2. Include everything with a value, including assets you say are not matrimonial, with a short note on why.
  3. Use a consistent valuation date and say what it is; see the valuation date for matrimonial assets.
  4. Reconcile before signing. Affidavit against tax returns against bank statements.
  5. Explain the odd items in advance rather than being asked about them.
  6. Correct errors immediately by supplementary affidavit. Speed is the whole defence.
  7. Answer discovery fully and on time.

Done properly, disclosure is unglamorous administrative work that takes a weekend. Done badly, it becomes the main issue in the case, and by the time you reach the ancillary matters hearing, a party whose figures are trusted is arguing about principles, while a party whose figures are not is arguing about themselves. Only one of those is a good place to be.
