Disclosure is the largest source of avoidable cost in most family files, and almost all of that cost is generated in the first three weeks by people who did not know what a good response looks like. This guide is about how to respond, not what your jurisdiction requires. The mechanisms differ — Alberta uses a Notice to Disclose, Ontario a Financial Statement, US states their own disclosure rules and forms. What each demands, and by when, is a question for your lawyer.
| What disclosure is | The obligation to produce a full and accurate picture of what you earn, own and owe. |
|---|---|
| Why it exists | Nothing — support, property division, settlement — can be calculated without it. |
| The obligation is usually ongoing | It generally does not end when you send the first package. Material changes normally have to be disclosed too. |
| The most expensive mistake | Producing a disorganised partial package, which generates follow-up requests and legal fees on both sides. |
| The most serious mistake | Withholding. Consequences can include costs, adverse inferences, and agreements being set aside later. |
| What is often sworn | Many disclosure documents are sworn or made under penalty of perjury. Treat those differently from the rest. |
| If you cannot produce something | Say so, in writing, with the reason and a date. Do not leave a gap. |
Keeping track of dates like these across a stack of letters is exactly what SortMyDivorce does — start a free trial, no card needed.
Disclosure requests vary in form but converge on the same picture. Expect to be asked for the following — a fuller list is in the documents you will need:
Income. Tax returns and assessments, usually three years. Recent payslips. Anything from other sources — employment insurance, pensions, benefits, rental income, investment income.
Business and corporate interests. Financial statements for self-employment, partnerships, privately held corporations. This is where most disputes live, because income can be structured in ways that make a single line on a return an unreliable guide.
Accounts. Bank statements and credit card statements, typically six months, sometimes longer.
Assets. Investment and retirement accounts, property, vehicles, anything of significant value.
Liabilities. Mortgages, loans, credit balances, tax owing.
A budget. Monthly expenses, which is often the most tedious item and the one people leave to last.
A sworn statement listing income, assets and liabilities.
Anything you claim is excluded or exempt. Property brought into the relationship, inheritances, gifts, certain damages awards — and, critically, the documents that trace it. Exemption claims live or die on tracing.
The difference between a good response and a poor one is not honesty — most people are honest. It is organisation, and it is worth real money.
Start the day it arrives. The deadline will be shorter than the time it takes to obtain older bank statements or get financial statements out of an accountant. The tax returns are the easy part; start with the hard part.
Map the request against what you have. Go through it item by item and mark each: have it, can get it, cannot get it, not applicable. That map is the whole plan, and it tells you within an hour whether the deadline is realistic.
Assemble it in the order asked for. If the request has sixteen numbered categories, deliver sixteen labelled sections. This sounds trivial. It is the single largest determinant of whether you get a follow-up request, and follow-up requests are billed on both sides.
Label every file. 03-payslips-May-July-2026.pdf, not scan_0047.pdf. Someone has to identify what each document is, and if it is not you, it is someone charging by the hour.
Mark what is not applicable, explicitly. A missing item and an inapplicable item look identical from outside. "Item 7 — not applicable, no partnership interests" closes the point. A silent gap invites a chasing letter.
Send it as one package, once. A drip feed of documents over three weeks is the most expensive way to disclose. Every instalment has to be logged, checked against the request and reconciled.
Keep a record of exactly what you sent and when. A dated index of the package. Disputes about whether something was produced are common and are resolved by records, not recollection.
This is where people get into trouble, and it is entirely avoidable.
Never leave a silent gap. A missing item with no explanation reads as evasion, and it will be treated as evasion whether or not that is fair.
Instead, in writing, state: what you cannot produce, why, what you have done to try, and when you expect to have it. "Item 9 — corporate financial statements for 2024 and 2025 provided; 2023 requested from my accountant on 4 August, expected by 30 August."
That converts a gap into a managed item. It also creates a record of reasonable conduct, which matters if the timeline is ever examined.
Some jurisdictions provide a specific form for this — Alberta, for example, has a Response to Request for Disclosure form for setting out why full disclosure cannot be provided. Ask your lawyer whether one applies.
It is worth being blunt about this, because the temptation is real and the reasoning behind it usually sounds sensible to the person doing it.
The consequences of incomplete or dishonest disclosure vary by jurisdiction but broadly include: costs orders against the party who withheld; adverse inferences, where a court is entitled to assume the undisclosed thing is unfavourable to you; the agreement being set aside later, sometimes years later, when the non-disclosure comes out; and in serious cases involving sworn documents, consequences that are more serious still.
The asymmetry is what makes it a bad bet. Disclosing an inconvenient asset costs you a share of that asset. Being found to have hidden it can cost you the settlement, the costs of the litigation, and your credibility on every other issue in the case.
If there is something you are worried about disclosing, that is a conversation to have with your own lawyer — who is on your side, and who can tell you whether the thing you are worried about is actually a problem. It is very often less of a problem than the person imagines, and always less of a problem than concealing it.
Most disclosure includes at least one document that is sworn, affirmed, or signed under penalty of perjury — typically the statement of income, assets and liabilities.
Treat that document differently from the rest of the package. Read every line. Do not sign it because someone is waiting for it. If you are unsure whether something belongs on it, ask before signing rather than after.
The rest of the package is documents. That one is testimony.
In most systems the obligation is continuing rather than a single event. If your income changes materially, if you receive something significant, if an asset is sold — those generally have to be disclosed as they happen, not saved for a later stage.
The practical version: keep a note of anything material that changes after your first package goes out, and raise it with your lawyer rather than deciding for yourself whether it matters.
Disclosure runs both ways, and the other side's package deserves the same attention you gave your own.
Check it against what was requested, category by category. Note what is missing, what is partial, and what raises a question. Then give your lawyer a list rather than an impression — "items 6, 8 and 11 are absent and the bank statements skip March" is actionable in a way that "their disclosure is incomplete" is not.
If material is missing, there are mechanisms to compel it. What those are and how they work depends on where you are, and it is covered in our jurisdiction-specific guides.
Verification note. This guide is deliberately structural. It does not state disclosure deadlines, forms or consequences for any jurisdiction other than the Alberta material cited above, because those differ in every province and state and a wrong figure would be worse than none. The general consequences of non-disclosure described are widely recognised principles rather than the rule of any single jurisdiction. Confirm what applies to you with your own lawyer.
It depends on the mechanism used and where you are. Alberta's Notice to Disclose specifies one month from service. Other jurisdictions set different periods, and court orders can set their own. Check the document you received and confirm with your lawyer.
Generally yes — disclosure and division are different questions. Something may need to be disclosed and still be excluded from division, and in most systems the way you establish an exclusion is precisely by producing the documents that trace it. Withholding it makes the claim harder to run, not easier.
Do not respond by withholding your own. Raise it with your lawyer, be specific about what makes you think so, and ask what mechanisms are available. There usually are some.
That is a decision for your lawyer, not for you. Relevance objections exist in most systems, but deciding unilaterally that something does not matter is a risk, and it looks like concealment even where it is not.
Raise it. In most systems the obligation continues, and a change disclosed promptly is unremarkable while the same change discovered later is not.
