The documents, statements, and records to collect and secure — before anything goes missing.
Who this is for: People in Ontario who are separating or have just separated and need to get organized fast. What you'll get: a complete, checkbox-style list of the documents to collect, where each one comes from, and how to keep them safe — so your lawyer (and you) aren't scrambling later.
⚖️ This is a general guide, not legal advice. It can't account for your specific situation. Use it to get oriented, then confirm the details with a licensed Ontario lawyer.
Why this matters
Ontario family law runs on financial disclosure. Whether you settle at the kitchen table, in mediation, or in court, both people must lay out what they own, what they owe, and what they earn — usually as of two key dates: the date you married and the date you separated. If you lived common law rather than married, the Family Law Act's property equalization does not apply to you — but the date you began living together still matters, because any claim you make to property held in your partner's name is measured from it. Gathering this early does three things:
- It makes settlement faster and cheaper.
- It protects you if records later become hard to access.
- It establishes the separation date, which anchors many calculations.
Tip: start a single folder (paper and digital) the day you decide to separate. Copy, don't remove, shared records — and don't delete anything.
1. Identity and relationship documents
These prove who you are and the status of your relationship.
- Government-issued photo ID (driver's licence, passport) — you already have these
- Marriage certificate — order from ServiceOntario if you can't find the original
- Cohabitation, marriage, or prenuptial agreement, if you signed one — your own files or the drafting lawyer
- Any prior court orders or agreements (from a previous relationship, e.g., existing support) — your files or the court
- Immigration / sponsorship documents, if relevant — your files or IRCC
Why it matters: an existing domestic contract can change everything about how property and support are handled — find it first.
2. Income records
Used to calculate spousal and child support and to complete your financial statement.
- Tax returns for the last 3 years — your copy or CRA "My Account"
- Notices of Assessment for the last 3 years — CRA
- Recent pay stubs (last several) — your employer/payroll portal
- T4s, T5s, and other tax slips — employer, banks, CRA
- If self-employed or a business owner: business financial statements, corporate returns, draws — your accountant/bookkeeper
- Records of any other income: rental, investment, pension, benefits — the payer or your statements
3. Bank, credit, and everyday finances
- Chequing and savings statements (all accounts — joint and individual) — your bank
- Credit card statements — each card issuer
- Line of credit / overdraft statements — your bank
- A snapshot of balances at the date of marriage and at the date of separation — historical statements; ask the bank if needed
⚠️ Watch out: you need the balances on those two specific dates, not just today's. If you don't have month-end statements that bracket those dates, request them now while access is easy.
4. Property: the home and other real estate
- Deed / transfer for any property you own — your closing lawyer or the land registry
- Mortgage statements showing the current balance — your lender
- Recent property tax bills and home insurance policy — the municipality / your insurer
- Any appraisal or recent valuation — appraiser; or arrange one
- Rental / lease agreement, if you rent — your landlord
Why it matters: the home you live in at separation (the matrimonial home for married couples) often gets special treatment under the Family Law Act — its paperwork deserves extra care.
5. Pensions, retirement, and investments
Pensions are frequently a couple's largest asset after the home — and the easiest to overlook.
- Workplace / defined-benefit pension statements, and a valuation for family-law purposes if available — your plan administrator
- RRSP, RRIF, TFSA, RESP, RDSP statements — the financial institution
- Non-registered investment account statements — your brokerage
- Values at marriage and at separation, where you can get them — historical statements
Tip: ask your pension administrator for a Family Law Value statement. There's a process specifically for valuing and (if agreed) dividing pensions on separation — don't try to estimate it yourself.
6. Debts and liabilities
It's not just about assets — debts get divided too.
- Loans (personal, car, student) — each lender
- Outstanding tax owing — CRA
- Balances on all credit cards and lines of credit (also in Section 3) — issuers
- Co-signed or guaranteed debts — the lender
7. Children's documents
- Birth certificates — ServiceOntario
- Health cards and any medical / special-needs records — your files / provider
- School records and any childcare agreements/receipts — the school / provider
- Passports and travel consent documents — your files / IRCC
- Records of child-related expenses (childcare, activities, health) for Section 7 support — your receipts
8. Communication and parenting records
Keep these factual and organized — they can matter if parenting becomes contested.
- A parenting log / calendar of who the children are with and when
- Messages and emails relevant to parenting or finances — save, don't delete
- Notes of significant events (factual, dated) — your own record
⚠️ Watch out: do not record people without understanding the legal limits, and don't access an ex's accounts or devices without permission. Improperly obtained records can backfire and create their own legal problems.
9. Accounts and digital security to separate
Separation has a digital side. Protect your privacy and your finances.
- Change passwords on personal email, banking, and key accounts — do this early
- Disentangle shared logins (streaming, cloud storage, password managers, shared notes)
- Update two-factor authentication to a device only you control
- Review joint accounts and authorized users — talk to your bank about freezing or splitting where appropriate
- Check beneficiary designations (insurance, RRSP, pension) — but get advice before changing anything mid-separation, as some changes are restricted
⚠️ Watch out: don't unilaterally drain a joint account or cancel the other person's access to necessities. Some moves that feel protective can be held against you. When in doubt, ask your lawyer first.
The two-date asset & debt table
This is the single most useful thing you can prepare. Fill it in for everything you own and owe.
| Item | Owner (A / B / Joint) | Value at marriage/cohabitation | Value at separation | Source document |
|---|---|---|---|---|
| Home | $______ | $______ | ||
| Mortgage | $______ | $______ | ||
| Pension (A) | $______ | $______ | ||
| RRSP / TFSA | $______ | $______ | ||
| Bank accounts | $______ | $______ | ||
| Credit cards | $______ | $______ | ||
| Vehicle(s) | $______ | $______ | ||
| Business | $______ | $______ | ||
| Other: ______ | $______ | $______ |
Keeping it all safe
- Make copies of every original — keep originals in a secure place
- Store digital scans in an account only you can access (not a shared cloud folder)
- Keep a backup (encrypted drive or separate secure account)
- Bring the organized folder — not a shoebox — to your first lawyer meeting
Tip: name your files clearly (
