Separation Agreement Template: What to Include and Why

A separation agreement is a legally binding contract between spouses that defines how property, debts, custody, and support will be handled during and after separation. When done properly, it becomes the foundation of your divorce settlement — and in many cases, the court adopts it as the final order with minimal modification.

When done poorly — or with missing provisions — it creates expensive disputes that could have been avoided.

What a Separation Agreement Covers

A comprehensive separation agreement addresses seven core areas:

1. Property Division Every asset acquired during the marriage needs to be assigned to one spouse or sold and divided. This includes the marital home, vehicles, bank accounts, investment accounts, personal property, and any business interests.

Be specific. "Wife gets the house" is insufficient. The agreement should specify: who retains the property, how the other spouse's equity share is paid (refinance buyout, offset against other assets, installment payments), and the deadline for completing the transfer.

2. Debt Allocation Joint debts don't disappear in divorce — creditors aren't bound by your separation agreement. But the agreement establishes which spouse is responsible for each debt. Include all mortgages, auto loans, credit cards, student loans, medical debt, and personal loans.

3. Retirement Accounts Dividing retirement accounts (401(k), IRA, pension) requires a Qualified Domestic Relations Order (QDRO), which is a separate court order directed at the plan administrator. Your separation agreement should specify the division — typically a percentage of the marital portion — and who is responsible for drafting and filing the QDRO.

4. Spousal Support (Alimony) If one spouse will pay support to the other, specify: the amount, frequency (monthly, biweekly), duration (fixed term or until a triggering event like remarriage), and whether it's modifiable. Also address whether support is taxable to the recipient — the 2017 Tax Cuts and Jobs Act eliminated the deduction for alimony payments in agreements executed after 2018.

5. Child Custody and Parenting Time The parenting plan section should cover: the regular weekly schedule, holiday and vacation rotations, transportation arrangements, decision-making authority (medical, educational, religious), communication protocols between parents, and procedures for schedule changes.

6. Child Support Most states use formula-based calculations (income shares or percentage of income models). Your agreement should include the amount, who carries health insurance for the children, how uninsured medical expenses are split, and who claims the children as dependents for tax purposes.

7. Miscellaneous Provisions These catch the details that cause conflict later: who keeps which pets, how shared subscription accounts are handled, life insurance requirements (often mandated to secure support obligations), and dispute resolution procedures for future disagreements.

Making It Enforceable

A separation agreement is only as strong as its enforceability. To hold up in court:

• Both spouses must have had the opportunity to review the agreement with independent legal counsel
• Neither spouse can have been coerced or pressured into signing
• Financial disclosure must be full and honest — agreements based on hidden assets can be voided
• The agreement must be in writing and signed by both parties
• Notarization is required in many states

Common Mistakes

Being vague about the marital home. "We'll figure out the house later" is the most expensive sentence in family law. Specify: sell now, refinance by a certain date, or one spouse buys out the other's equity.

Forgetting about taxes. Property transfers between spouses during divorce are generally tax-free, but selling a home, liquidating investments, or dividing retirement accounts can create tax liability. The agreement should address who pays.

Ignoring future changes. Children grow up. Incomes change. Include modification procedures and triggers (relocation, income change exceeding X%, child reaching a certain age) in the agreement rather than assuming everything will stay the same.

Starting the Process

Drafting a separation agreement requires knowing your full financial picture — every asset, every debt, every source of income. The Divorce Preparation Checklist & Roadmap walks you through this inventory systematically, so when you sit down to draft your agreement (or hire an attorney to draft it), you have the complete picture.
