What Happens to Your Estate Plan After a Divorce in Illinois?

 Posted on April 03, 2026 in Estate Planning

If you made a will, set up a trust, or named a spouse as a beneficiary on a life insurance policy or retirement account, a divorce doesn't automatically update every part of it to reflect your new situation. You will need to take care of that proactively.

If you’re wondering what estate planning documents need your attention after your divorce, a Geneva estate planning attorney can help.

What Automatically Changes in an Illinois Estate Plan After a Divorce? 

Illinois does offer some protection to someone who forgets to update their estate plan after a divorce. Under 755 ILCS 5/4-7(b) of the Illinois Probate Act, any provision in your will that leaves something to a former spouse is automatically revoked when your divorce becomes final. The law treats it as if your ex-spouse had died before you. This means your ex will not inherit what your will once directed to them, even if you never officially changed it.

The same automatic revocation applies to your ex-spouse's role as a fiduciary. A fiduciary is a person designated to manage someone else’s affairs. They must act for the benefit of the other person, not themselves. If your will named your spouse as executor – the person responsible for managing your estate after you die – that appointment is also revoked by the divorce.

This is a good starting point, but it doesn’t address all the issues involving your will. Revoking your ex-spouse's share doesn’t mean that share always goes to someone else. Depending on how your will is written, those assets may pass to alternate beneficiaries if you named them. They may also fall into what is called intestacy, meaning Illinois law decides where they go. This may not end up being where you want those assets to go at all.

What Parts of an Illinois Estate Plan Aren’t Always Changed by Divorce?

If someone doesn’t consider their wishes for an updated estate plan after their divorce, they can run into serious issues later. Considers some elements of an estate plan you will need to address directly.

Accounts and Policies with Beneficiary Designations

Life insurance policies, retirement accounts like 401(k)s and IRAs, and certain bank accounts don’t go through your will at all. They pay out directly to whoever you named as a beneficiary when you set them up. Illinois law will usually cancel your ex-spouse's claim to your life insurance after a divorce, but not to retirement accounts or bank accounts.

If you named your spouse as the beneficiary on those accounts and you never changed it, they may still collect that money after you die, even though you are divorced. The only way to prevent that is to update the beneficiary designations yourself. It’s also safest to check that the claim on your life insurance was truly canceled.

Trusts

If you created a living trust and named your spouse as a beneficiary or trustee, divorce doesn’t remove them from that role under Illinois law. You need to actively amend or restate the trust to reflect your new situation.

Powers of Attorney

In many cases, Illinois law automatically revokes a former spouse’s authority under a power of attorney upon divorce. This means they can’t make decisions for their ex-spouse if the ex becomes incapacitated. However, it is still wise to update these documents to ensure your wishes are clearly reflected.

What You Should Review in Your Estate Plan After Your Divorce Is Final

You should do a complete estate plan review in the period right after your divorce is finalized. That means looking at every document and account that carries your former spouse's name.

Items to review and update include:

• Your will
• Any revocable living trusts
• Life insurance beneficiary designations
• Retirement account beneficiaries (401k, IRA, pension)
• Payable-on-death and transfer-on-death account designations
• Durable power of attorney for finances
• Healthcare power of attorney and advance directive

You may also want to think about guardianship designations for minor children and whether your current plan reflects who you now want to make decisions for you if you become incapacitated.
