Gather every document that has both names on it

Start with the obvious and work outward. Any account, property, loan, or contract with both of your names on it is a marital asset or liability, and the court will want to see it.

Pull together: - Marriage certificate (you will need certified copies, not just a scan) - Mortgage or lease agreements - Joint bank account statements, at least 12 months back - Joint credit card statements, same window - Vehicle titles with both names - Any business ownership documents if you co-own a business - Life insurance policies listing a spouse as beneficiary

Where people get tripped up: accounts that started as individual but had a spouse added later, or vice versa. In most states, commingled assets get treated as marital property regardless of whose name came first. Pull statements for anything either of you touched during the marriage, even if it originally belonged to just one of you.

If online access has been changed or you suspect accounts have been moved, screenshot what you can see and note the date. Courts take documentation of financial behavior during separation seriously.

Document all income sources for both of you

Your attorney and the court need a clear picture of what money has been coming in, from every direction. This is especially important if you stepped back from your career during the marriage. Research consistently shows that divorce produces a persistent income decline for women, particularly those who reduced work for family reasons. The rebuild is real, and the documentation you gather now is the foundation of any support calculation.

Collect: - W-2s and 1099s for the past three years - Federal and state tax returns for the past three years (both your copies and, if accessible, joint filings) - Recent pay stubs, at least two to three months - Bank statements showing direct deposit history - Any documentation of bonuses, commissions, stock options, or restricted stock units - Pension or retirement account statements: 401(k), IRA, pension plan summaries - Social Security statements if you are within range of retirement planning

If your spouse is self-employed, this gets more complicated. Business bank statements, profit and loss statements, and Schedule C filings all become relevant. Note anything that seems inconsistent, large cash withdrawals, unusual transfers, unexplained income dips. Your attorney will want to know.

Compile a full picture of what you own and what you owe

Marital property division requires a complete inventory: assets on one side, debts on the other. Do not assume anything is too small to include or too obviously yours to matter.

Assets to document: - Real estate: mortgage statements, property tax records, any appraisals - Investment accounts: brokerage statements showing current holdings and purchase history - Retirement accounts: current balances and statements from the start of the marriage if you can obtain them - Vehicles: titles and current loan balances - Valuable personal property: jewelry, artwork, collectibles (photos with approximate values if available) - Business interests: any ownership stake, buy-sell agreements, valuation documents

Debts to document: - Mortgage balance and payment history - Car loans - Student loans (these are treated differently depending on when they were taken out) - Personal loans - Credit card balances for every card, joint or individual - Any tax debt owed to the IRS or state

The tricky zone here is debt that one spouse ran up without the other's knowledge. Depending on your state, you may still be partially liable. Get a copy of your credit report now at annualcreditreport.com so nothing surprises you later.

Gather documents related to children if custody is part of the case

If you have children, the documentation layer expands. Custody and support determinations require their own paper trail, and judges care about specifics, not impressions.

Collect: - Birth certificates for each child - School records: enrollment, attendance, any IEPs or 504 plans - Medical records: pediatrician, specialists, therapists (if applicable) - Health insurance cards and documentation of who currently carries coverage - Records of extracurricular activities, tutoring, or childcare, including costs and who has been paying - Any written communication between you and your spouse regarding the children: texts, emails, parenting app logs

If there are concerns about the other parent's behavior or fitness, document incidents with dates, descriptions, and any witnesses. Courts want contemporaneous notes, meaning written at the time, not reconstructed later. A simple notes app with dates works. A notebook with dates works. A single email you sent to yourself at the time of an incident works.

Child support calculations vary by state but typically factor in both parents' incomes, custody time, and the cost of healthcare and childcare. Having exact numbers ready moves this process faster.

Secure your personal identification and estate documents

This category is easy to overlook because these documents feel like background noise until you need them urgently.

Gather: - Your passport and any passport belonging to your children - Social Security cards for yourself and your children - Birth certificate for yourself - Any prenuptial or postnuptial agreements - Wills and trust documents, especially if either of you is named as beneficiary or executor - Power of attorney documents - Any existing separation agreements

One thing people rarely think about until it is too late: as soon as you file, or sometimes before, you should update your will and beneficiary designations. Life insurance, retirement accounts, and investment accounts pass by beneficiary designation, not by whatever your will says. If your spouse is still listed and something happens to you during proceedings, those assets could still go to them regardless of the divorce outcome.

Also make sure your personal identification documents are in a safe location you control. A safe deposit box in only your name, a trusted family member's home, or a fireproof safe at your residence are all reasonable options.
