Updating an Estate Plan After a Marriage, Divorce, or Death

Estate planning is all about providing a smooth, predictable transition when you or a loved one passes away. But before the event that would trigger an estate plan can happen, other major events can undermine or even nullify the estate plan’s objectives. 

A marriage, a divorce, or the death of a loved one can change your family in ways that your current estate plan is not built to handle. One of the most common situations that Illinois estate planning attorneys encounter is a client who created a solid plan years ago but never updated it after a major life event. 

This can mean that assets go to the wrong person, family members are left without protection, or dearly held wishes go completely unfulfilled. None of these are ideal scenarios. If any of these changes have happened in your life in 2026, reviewing and updating your estate plan is very important. 

Why Does Getting Married Mean You Need to Update Your Estate Plan?

Marriage changes almost everything about who should receive your assets and who should make decisions for you if you cannot make them yourself. If you had an estate plan before you got married, it almost certainly does not reflect your relationship with your new spouse. 

How Marriage Changes an Estate Plan

A will or trust you created before marriage doesn’t automatically include your new spouse. That means if something happens to you, your spouse may not inherit what you intended. He or she may have no legal authority to handle your finances or medical care. After getting married, you should review and likely update all of the following:

• Your will, to reflect your spouse as a beneficiary and possibly as your executor
• Your revocable living trust, to add your spouse and address how assets will be managed
• Beneficiary designations on life insurance policies, retirement accounts, and bank accounts
• Your durable power of attorney, so your spouse can manage your finances if you are incapacitated
• Your healthcare power of attorney, so your spouse can make medical decisions on your behalf

For those with children from a prior relationship, carefully updating an estate plan is especially important. Without the right structure in place, assets intended for your children could pass entirely to your new spouse, or vice versa. A trust can help balance these competing interests in a way that even the best-written will often cannot.

Does Illinois Automatically Protect a New Spouse?

Illinois does offer some protections for surviving spouses under the Illinois Probate Act (755 ILCS 5/), including a statutory share of the estate. However, relying on these default rules instead of a thoughtful estate plan often leads to an outcome that isn’t what you actually want. Updating your documents puts you in control rather than leaving it to the state.

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

Divorce has significant and immediate effects on your estate plan. Illinois law does provide some automatic protections when a divorce is finalized, but they do not cover everything, and they do not protect you at all while your divorce is still in progress.

What Illinois Probate Law Says About Divorce and Wills/Trusts 

Under 755 ILCS 5/4-7 of the Illinois Probate Act, a final judgment of divorce automatically revokes any provisions in your will that benefit your former spouse. Similarly, under the Illinois Trust Code, divorce can revoke trust provisions in favor of a former spouse. These automatic revocations offer a baseline of protection, but they are not a substitute for a comprehensive update.

The automatic revocations under Illinois law do not affect beneficiary designations on assets that pass outside of your will, such as life insurance policies, IRAs, and 401(k) accounts. Federal law governs most retirement account beneficiary designations, meaning your ex-spouse could still inherit those funds if you never updated the form. Many people are surprised to learn this, and it is one of the most preventable estate planning mistakes we see.

After a divorce, you should also revisit:

• Your durable power of attorney, which may still name your former spouse
• Your healthcare power of attorney and living will
• Any trusts that name your former spouse as trustee or beneficiary
• Guardianship designations if you have minor children

Acting now prevents serious unintended consequences later.

How Should You Update Your Estate Plan After a Loved One Dies?

The death of a spouse, parent, child, or close family member often goes unaddressed in estate planning until a problem comes up. Here are some of the common impacts of a loved one’s death on an estate plan. 

When a Beneficiary Dies

If a named beneficiary in your will or trust passes away before you do, that portion of your estate may fall into what is called a lapse. Depending on how your documents are written, the assets may pass to that person’s heirs, revert to your estate, or be distributed in a way you never intended. Updating your plan to name a new beneficiary or add contingent beneficiaries prevents this problem.

When a Fiduciary Dies

A fiduciary is the person you have named to carry out your wishes, such as your executor, trustee, or agent under a power of attorney. If that person dies and you have not named a successor, your family may face delays and court involvement at an already difficult time. Reviewing and updating your named fiduciaries after a death in the family is one of the most important steps you can take.

When a Spouse Dies

The death of a spouse often requires a full review of the surviving spouse’s estate plan. Assets often transfer automatically, tax situations change, and a plan that made sense for two people will need to be rebuilt around one. This is also a time to consider long-term care planning, updated beneficiary designations, and whether a trust structure still makes sense for your situation.
