An affidavit is sworn evidence, not argument. That single sentence, properly absorbed, fixes most of what goes wrong with the affidavits people write for themselves. Your job is not to persuade the judge that you are the wronged party. Your job is to put facts in front of the judge, supported by documents, in an order that can be followed, and to let the argument be made by your lawyer, or by the facts themselves.

In family proceedings in Singapore, most matters are decided on affidavit evidence rather than live testimony. In an ancillary matters hearing, the judge may never hear you speak. The affidavit is you. It is worth the time it takes to do properly.

The reframe: you are a witness, not an advocate

Read your draft and ask, of every sentence: would a neutral witness say this? A witness says what they saw, heard, did, paid and received. An advocate says what it means and why the other side is wrong.

Compare these two versions of the same point:

The first tells the judge what to think and gives them nothing to work with. The second lets the judge reach the conclusion themselves, which is far more powerful, and it survives a challenge because every element is documented. A judge cannot make a finding on “irresponsible”. A judge can make a finding on three unpaid months.

This is the practical meaning of facts, not adjectives. Strike out “always”, “never”, “constantly”, “abusive”, “manipulative”, “selfish”, “toxic”. Replace each with the incident that made you reach for the word. If you cannot produce one, the word was doing no work.

Structure that a judge can follow

Format conventions exist for a reason: they let a judge find things. Follow them.

  • Numbered paragraphs, consecutively, throughout. Everyone will refer to your evidence by paragraph number, including the judge, so this is not cosmetic.
  • One point per paragraph. If a paragraph contains three distinct assertions, the other side can answer one and ignore the other two.
  • Chronological within each topic. Dates in the margin of the reader’s mind. Where you are covering several topics, use short headings and keep each topic’s chronology intact rather than looping back and forth.
  • Open with who you are and what the affidavit is for. One short paragraph: your name, your role in the proceedings, and that you make the affidavit in support of, or in response to, a specific application.
  • Deal with the other side’s points in their order when replying, so the judge can read the two documents side by side. Answering paragraph 14 at your paragraph 9 makes the comparison harder than it needs to be.
  • End with what you are asking for, briefly and specifically.

Write in the first person, in your own words

“I”, not “the Applicant”. Plain English, not borrowed legalese: “I saw”, “I paid”, “he told me”. You do not need “aforementioned”, “herein” or “the said flat”.

Your lawyer will shape and tighten the draft, and should. But the voice must be yours. An affidavit written entirely in a solicitor’s register, from a client whose actual English is different, reads as coached and is an easy target if you are ever cross-examined on it. The best drafting process is usually: you write a first attempt with the documents in front of you, your lawyer cuts and reorders it and tells you where evidence is missing, you fill the gaps.

What to leave out

Most over-long affidavits are long because of material that could not affect the outcome. Cut:

  • Insults and characterisation. Nothing marks an affidavit as unreliable faster. It also tends to invite the same in reply, and then the judge has two documents of noise.
  • Hearsay dressed as fact. “My sister told me she saw him at a hotel” is not evidence that he was at the hotel. If it matters, get an affidavit from your sister. If you must mention it, say plainly that you were told it and by whom.
  • Speculation about motive. “He only wants care and control to reduce maintenance” is a guess. You can state the facts that gave you the impression; you cannot state what is in his head.
  • Old history with no bearing on the issues. Conduct from fifteen years ago rarely affects the division of assets or a maintenance figure. In a children’s matter, ask whether the incident tells the court something about parenting now.
  • Argument about the law. Cases and statutes belong in submissions, not in your evidence.
  • Screenshots dumped by the hundred. Select. Fifty pages of messages that nobody will read persuade less than four exchanges that make the point.

Conduct is not entirely irrelevant: it can matter where it is extreme, or where it directly affected the finances, for example assets deliberately dissipated. But the test is always relevance to a decision the judge has to make, not how badly it hurt.

Exhibits: every assertion about money needs a document

Exhibits are the documents you attach and refer to. They are the difference between an assertion and evidence.

The working rule: if you say a number, attach the document that proves it. Income: payslips, tax notices of assessment, CPF statements. Expenses: bills, invoices, receipts, standing instructions. Payments made or missed: bank statements with the relevant lines marked. Property: the option to purchase, the mortgage statement, the CPF withdrawal history. Renovation and contributions: the contract and the transfer records.

Conventions to follow:

  • Mark exhibits with your initials and a number, in the order they are first mentioned: “exhibit TAB-1”, “TAB-2”, and so on. Do not mention TAB-7 before TAB-3.
  • Each exhibit gets a cover sheet identifying it and referring to your affidavit, and the exhibits are signed by the person before whom you swear.
  • Refer to exhibits in the body (“a copy of the tenancy agreement is at exhibit TAB-2”) and give the page number if the exhibit is long.
  • Highlight the relevant line. If a bank statement matters because of one transfer on 3 March, mark it. A judge should never have to hunt.
  • Provide a certified translation for documents not in English.
  • Never edit a document. Redacting genuinely irrelevant private third-party information can be acceptable, but altering, cropping to mislead or omitting pages is not, and it is usually discovered.

Where you need documents that the other side holds, the answer is not to guess in your affidavit: it is discovery and interrogatories, the formal process for requiring documents and answers.

Consistency with everything else you have filed

The fastest way to lose a case is to contradict yourself. Before you swear anything, read it against:

  • Your affidavit of assets and means, the detailed schedule of what you own, earn, owe and spend. If your AOM says your monthly expenses are $3,200 and your maintenance affidavit says you need $6,000, one of them is wrong and the judge will notice.
  • Your statement of claim and statement of particulars, and any earlier affidavit in the case.
  • Anything filed in related proceedings: a maintenance application, a protection order application, an application to vary.
  • Documents you have already disclosed. Your tax returns and your affidavit have to tell the same story about your income.

Where there is a genuine inconsistency, explain it in the affidavit rather than hoping it is missed. “My earlier affidavit stated $4,000; that was an error, the correct figure is $4,600, as the payslip at TAB-5 shows” costs you very little. Being cross-examined on an unexplained discrepancy costs you a great deal. The related traps are set out in common financial disclosure mistakes.

Length discipline

Judges in the Family Justice Courts read a very large number of these. Assume yours gets careful but finite attention.

Three habits help. First, put the important material early: do not build to a climax on page 40. Second, cut every sentence that does not carry a fact, a date, a figure or an exhibit reference. Third, when you are describing a long-running pattern, give the pattern in one sentence and then two or three dated, evidenced examples rather than twenty. Twenty examples do not multiply the effect; they bury it.

A useful test: hand your draft to someone who does not know your marriage and ask them to tell you back what happened and what you want. If they cannot, the judge will struggle too. It is also worth reading how to read a court order to see the kind of precise, dated, unambiguous language the court works in: that is the register your affidavit should aim at.

Swearing or affirming it

An affidavit becomes evidence when you swear or affirm it before an authorised person, a commissioner for oaths, typically at a law firm or at the courts. Affirming is the non-religious equivalent and has exactly the same effect.

Practical points: bring your identification; do not sign the affidavit in advance, because you sign in the commissioner’s presence; you will sign each page and each exhibit cover sheet as directed; and if the affidavit is in English but you are not comfortable in English, it must be interpreted to you and a jurat recording that is added. Do not let anyone gloss over that step. See interpreters and language in the family courts. Read the final version in full before you sign it, including the parts your lawyer drafted. You are the one on oath, not them.

The consequences of getting it wrong

A false affidavit is not a technical breach. You have sworn to the truth of the contents, and a deliberate falsehood can lead to contempt of court proceedings and potentially criminal liability. Beyond the formal consequences, credibility in a family case is close to indivisible: once a judge finds you untruthful about one thing, every disputed fact in your case is decided against you.

That includes omission. Leaving an account off your affidavit of assets and means because you think it is “not really matrimonial” is not a clever argument: it is non-disclosure, and it can lead to an adverse inference or a reopened order later.

Where you are genuinely unsure of a fact, say so: “to the best of my recollection”, “I believe, based on the statement at TAB-6”. Honest uncertainty is fine. False precision is not.

A last pass before you file

  1. Every paragraph numbered; one point each.
  2. Every figure supported by an exhibit, and the relevant line marked.
  3. Every adjective either deleted or replaced with the dated incident behind it.
  4. No hearsay presented as fact; no speculation about motive; no insults.
  5. Exhibits numbered in the order they appear and referenced in the text.
  6. Cross-checked against your AOM and everything else filed.
  7. The relief you seek stated clearly at the end.
  8. Read out loud once. Anything you would be embarrassed to have read back to you at an ancillary matters hearing comes out.
