I Need to Know What a Community Property Agreement is

A community property agreement is a contract that a married couple in a state that permits such agreements signs to specify how they want their property to be classified. Classification may be as community property or separate property, or a mix of the two. 

What Is A Community Property State?

In a community property state, property acquired during the marriage is generally treated as jointly owned, subject to exceptions under state law. How that property is divided in the event of a divorce depends on the applicable state’s laws. Some examples may include:

  • Real estate
  • Personal property
  • Savings
  • Retirement accounts
  • Debts acquired during the marriage

Community property laws vary by state. They were not created by the Uniform Marital Property Act of 1983. Wisconsin adopted its marital property system through legislation enacted in 1983, but community property systems existed in other states before that law.

However, there are instances when property may be considered separate property, primarily when it was acquired before the marriage or inherited by one spouse before or during the marriage. If you live in a community property state and buy a home while married, the home may be treated as community property even if only one spouse’s name appears on the title. The result depends on the state’s laws and the source of the funds used to acquire the property.

If you live in one of the ten community property states, your state law may allow for a community property agreement. This is an agreement between spouses that may classify some or all assets as community property. It may also state how those assets will pass when one spouse dies. However, community property does not automatically pass entirely to the surviving spouse unless the agreement, ownership document, or applicable law creates a right of survivorship.

Illinois is not a community property state. Its marital property rules generally apply when property is classified and divided during divorce. What happens to property when a spouse dies depends on title, beneficiary designations, joint ownership rights, trusts, wills, and applicable inheritance laws.

Some practitioners use this agreement in lieu of other planning for spouses in states that permit community property agreements. Be careful when entering into more sophisticated estate planning, such as trust planning, and make your estate planning team aware of any previous community property agreements. A previously signed community property agreement could interfere with the planning benefits of the trust by passing assets to the surviving spouse outright and causing the trust to remain unfunded.

Historically, the nine community property states have been Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin. Alaska later adopted an elective system that allows a married couple to treat all or part of their property as community property through a written agreement.

Why Property Classification Matters in Estate Planning

Property classification can affect ownership during marriage, transfers at death, and how an asset should be placed into a trust. A community property agreement may also affect tax reporting. Because the result depends on state law, the agreement, and the estate plan, spouses should review the related documents together. 

How an Agreement Can Affect Trust Funding

A trust generally controls only property transferred to it or made payable to it. A community property agreement may direct property to a surviving spouse in a way that conflicts with a revocable trust’s funding plan.

For example, a trust may divide assets between a survivor’s share and another trust created for tax or creditor purposes. If a separate agreement transfers qualifying property directly to the surviving spouse, that division may not occur. Property deeds, beneficiary forms, and assignment documents should be reviewed alongside the agreement.

Questions to Review Before Signing

Before signing a community property agreement, spouses should identify which assets it covers, whether any property will remain separate, and how it applies to business interests, retirement benefits, and out-of-state property.

They should also determine whether the agreement remains effective after relocation. Business owners should review transfer restrictions, succession plans, and buy-sell arrangements before changing an ownership interest’s character or title.

Coordinating the Agreement With the Rest of the Plan

A coordinated review should include wills, trusts, powers of attorney, property deeds, insurance policies, retirement accounts, and payable-on-death or transfer-on-death instructions. Each document may direct an asset differently, and the controlling document can vary by asset type.

Spouses should also review the plan after a major purchase, sale, inheritance, business transaction, relocation, or family change. Regular review helps confirm that ownership records still support the intended trust distribution. More information about the firm’s approach is available on the About Us page.

Frequently Asked Questions

Does a Community Property Agreement Replace a Trust?

No. The agreement addresses property classification or transfer, while a trust may provide management and beneficiary instructions after death or incapacity.

Can Separate Property Be Included in the Agreement?

An agreement may change the classification of certain property when permitted by law. Spouses should understand the tax, inheritance, and control consequences first.

Should an Existing Agreement Be Reviewed After Moving?

Yes. A move may affect how property rights and estate-planning documents are interpreted. The review should include the agreement, current titles, trust provisions, and applicable law.
