Can Your Spouse Claim a Share of a Family Trust in an Illinois Divorce?

 Posted on June 19, 2026 in Asset Division

If you are a beneficiary of a family trust and going through a divorce in 2026, you may wonder whether your spouse can reach those assets. The answer depends on how the trust was set up, when it was funded, and how distributions were handled during the marriage.

According to the CDC National Center for Health Statistics, there were more than 672,000 divorces in the United States in 2023 among 45 reporting states and Washington, D.C. For families with valuable assets in a trust, those divorce cases bring questions that go well beyond a typical property split. A St. Charles, IL divorce attorney can help you understand where your trust assets stand before property division talks begin.

Is a Trust Marital Property Under Illinois Law?

Illinois law draws a clear line between marital and non-marital property. Under the Illinois Marriage and Dissolution of Marriage Act, 750 ILCS 5/503(a), property acquired during the marriage is generally marital. But the statute lists exceptions.

Property received by gift or inheritance, including money from a trust created by a third party, is classified as non-marital. This means the principal of a trust set up by your parents or grandparents is not part of your marital estate, and your spouse cannot claim a share of it just because you are the named beneficiary.

The protection under the statute is not absolute. Whether a trust interest is shielded depends on who created the trust, when it was funded, and how trust money was handled during the marriage.

When Does Trust Property Become Marital Property in an Illinois Divorce?

Several things can put trust assets at risk of being treated as marital property.

Commingling

Once you receive a trust distribution, that money becomes your personal property. If you put it into a joint account or use it to pay shared bills, it can lose its non-marital status. Under Illinois law, non-marital funds can be mixed with marital funds to the point where their source cannot be traced. These may be reclassified as marital funds. This is a common problem for people who received regular distributions from a trust and did not keep that money separate.

Marital Funding

If you and your spouse funded a trust with income earned during the marriage, a court will not shield those assets just because they sit inside a trust.

Trustee Control

If you can demand distributions at will or act as your own trustee with broad powers, a judge may treat the trust like a personal account. If an outside trustee controls distributions, your interest is more likely to be treated as a future right than a current asset.

How Trust Distributions Affect Spousal Maintenance and Child Support in Illinois

Even when a trust's principal is protected from property division, trust income can still affect other parts of your divorce. Illinois courts look at income from all sources when setting spousal maintenance and child support.

Under 750 ILCS 5/504(b-3) and 750 ILCS 5/505(a)(3), a judge can count regular trust distributions as income when setting support orders. If a trustee has made steady payments to you over the years, a court may treat that pattern as proof that similar payments will continue.

What Happens to Your Former Spouse's Trust Designations After an Illinois Divorce?

If your spouse is named as a beneficiary or trustee in your trust, Illinois law gives you some protection once your divorce is final. Under the Illinois Trust Code, 760 ILCS 3/605(b), revocable provisions that benefit a former spouse are revoked when a divorce judgment is entered. This covers distributions to your ex and their role as trustee.

However, the trust document does not update automatically. If you want the trust document to reflect your current wishes, you have to formally revise it and relying on statutory revocation alone can cause problems if trust administration is later disputed.
