This is something I talk to clients about all the time, because a lot of people understandably assume that if they get married or divorced, their estate plan sort of updates itself automatically.
Unfortunately, it usually does not work that way.
In Illinois, marriage or divorce can affect certain parts of your estate plan, but that does not mean all of your documents are suddenly current, coordinated, and saying what you actually want them to say. In most cases, these life changes are exactly when I would recommend reviewing everything.

If You Get Married, Your Old Documents May No Longer Make Sense
When someone gets married, one of the first things I think about is whether their existing documents still match their life.
A lot of people signed a will, trust, or powers of attorney before they were married, and at the time, those documents may have made perfect sense. Maybe they named a parent, sibling, or someone else they trusted. But once you are married, that same plan may no longer reflect what you actually want.
For example, I often see situations where:
- an old trust still leaves everything to parents or siblings
- an old power of attorney still names someone other than the new spouse
- old beneficiary designations were never updated
- the overall plan just was not built with a spouse in mind
So while marriage is a huge legal and personal milestone, it does not automatically rewrite your estate plan for you.
If You Get Divorced, I Would Never Recommend Assuming Everything Is Fixed Automatically
Divorce creates even more confusion.
A lot of people think that once the divorce is final, their ex-spouse is automatically removed from everything across the board. I would not rely on that assumption.
Yes, Illinois law may revoke certain provisions in favor of a former spouse in some situations, but that does not mean every asset, every document, and every designation is now cleaned up the way you want. Estate planning does not work that neatly.
This is why, after a divorce, I strongly recommend reviewing:
- your revocable living trust
- your will
- your power of attorney for property
- your power of attorney for health care
- your living will
- your beneficiary designations on retirement accounts, life insurance, and bank accounts
From my perspective, the safest approach is simple: do not assume the law has handled everything for you.
Beneficiary Designations Are One of the Biggest Things People Miss
This is one of the most common problems I see.
People will update their trust or will, but they forget about the accounts that pass outside of those documents. That includes things like:
- life insurance
- IRAs
- 401(k)s
- payable-on-death accounts
- transfer-on-death accounts
Those assets usually pass based on the beneficiary form on file, not based on what your trust or will says. So even if the rest of your estate plan looks fine, one outdated designation can still cause a major problem.
That is why I always look at the full picture, not just the trust itself.
Powers of Attorney Matter Just As Much
A lot of people focus only on who gets what when they pass away, but I also look closely at incapacity planning.
If something happens to you while you are living, who do you want making financial decisions for you? Who do you want speaking with doctors and making medical decisions?
After marriage, many people want their spouse in those roles. After divorce, many people absolutely do not want their former spouse in those roles anymore. But unless those documents are updated, the wrong person could still be listed.
This is one of those issues that is easy to overlook until it becomes a real problem.
Your Estate Plan Should Match Your Life As It Is Now
Whenever a client gets married or divorced, I do not like taking a piecemeal approach. I prefer to review the whole plan together so everything works as one coordinated package.
That means looking at the trust, the will, the powers of attorney, and the beneficiary designations together. My goal is to make sure the documents actually reflect your current life, not the version of your life from several years ago.
Because at the end of the day, that is really the issue. Your estate plan should match your life as it is now.

Getting married or divorced in Illinois does not automatically create a complete estate plan, and it does not automatically fix an outdated one either.
If your family situation has changed, I think your estate plan should be reviewed too.
If you recently got married, are going through a divorce, or finalized one and have not updated your documents yet, this is exactly the kind of thing I help clients with during an estate planning consultation.
