A Divorce Settlement Agreement (also called a Marital Settlement Agreement, Separation Agreement, or Property Settlement Agreement) is a comprehensive legal document in which divorcing spouses agree on all the terms of their divorce, including the division of marital property and debts, spousal support (alimony), child custody and visitation, child support, and any other issues arising from the dissolution of the marriage. When approved by the court, it becomes part of the divorce decree and is enforceable as a court order.

Divorce settlement law is governed entirely at the state level, with each state having its own domestic relations code. The division of property follows one of two systems: equitable distribution (used by 41 states), where property is divided fairly but not necessarily equally based on factors listed in the state statute, or community property (used by 9 states: Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin), where marital property is presumptively split 50/50. The Uniform Marriage and Divorce Act (UMDA) provides the model framework for equitable distribution.

Spousal support (alimony) is determined under state-specific factors, such as the length of the marriage, each spouse's earning capacity, the standard of living during the marriage, and contributions to the other spouse's education or career. The Tax Cuts and Jobs Act of 2017 eliminated the federal tax deduction for alimony payments for divorce agreements executed after December 31, 2018, significantly affecting settlement negotiations.

A Divorce Settlement Agreement is needed in the following situations: when spouses agree to divorce and want to resolve all issues through negotiation or mediation rather than contested litigation; when an uncontested divorce is filed and the court requires a written agreement addressing all marital issues before granting the decree; when spouses are legally separating but not yet divorcing and need to formalize property division and support arrangements; when a previously entered divorce decree needs to be modified due to changed circumstances; and when spouses with significant assets, business interests, or complex financial situations need a detailed property division plan.

Additional scenarios include military divorces governed by the Uniformed Services Former Spouses' Protection Act (USFSPA), 10 U.S.C. Section 1408, divorces involving division of retirement accounts (requiring QDROs under ERISA Section 206(d)(3)), international divorces where assets are located in multiple countries, and divorces involving family businesses that must be valued and divided.

Attempting a divorce without a written settlement agreement -- even in an uncontested divorce -- invites future disputes and litigation. Courts in virtually every state require a written agreement before approving an uncontested divorce. Without one, the court will impose its own division, which may not reflect the parties' preferences. Post-divorce disputes over property, debts, and support are among the most common and expensive types of family law litigation.

A comprehensive Divorce Settlement Agreement must include the following elements:

Property division -- a complete inventory of all marital property (real estate, vehicles, bank accounts, investment accounts, retirement accounts, business interests, personal property) with the agreed division. For retirement accounts, the agreement must specify whether a Qualified Domestic Relations Order (QDRO) is required under ERISA.

Debt allocation -- identification of all marital debts (mortgages, car loans, credit cards, student loans, personal loans) and assignment of responsibility for each. The agreement should include indemnification provisions for debts assigned to the other spouse.

Spousal support -- whether alimony will be paid, the monthly amount, the duration (rehabilitative, durational, or permanent), the payment method, and the events that terminate the obligation (remarriage, cohabitation, death). Address the tax treatment of payments under post-2018 law.

Child custody -- physical and legal custody arrangements, the parenting schedule, holiday and vacation schedules, decision-making authority, and relocation restrictions, following the best interests standard.

Child support -- the monthly amount calculated under state guidelines, the income figures used in the calculation, provisions for healthcare, childcare, and educational expenses, and the duration of the obligation.

Health insurance -- which party will provide health insurance for the children, COBRA continuation coverage for the non-insured spouse (as mandated by 29 U.S.C. Section 1161 for employer-sponsored plans), and responsibility for uninsured medical expenses.

Tax matters -- filing status for the current tax year, allocation of dependency exemptions (though the personal exemption is currently suspended through 2025), and responsibility for any tax liabilities or refunds.

Insurance and beneficiary designations -- requirements to maintain life insurance policies naming children as beneficiaries, and obligations to update retirement account and insurance beneficiary designations.

Dispute resolution -- the method for resolving future disputes, typically mediation before litigation.

Full disclosure -- representations by both parties that they have fully disclosed all assets, debts, and income, with provisions for reopening the agreement if hidden assets are discovered.

Signatures and notarization -- both spouses' signatures, notarized, with a recommendation for independent legal review by each party.
