Let’s start with a simple truth:
Accidental disinheritance happens more often than most people think. Even if you have a will, trust, and investment plan in place, you can still unintentionally leave someone out—just by forgetting to update a beneficiary form or assuming your will covers everything (spoiler: it doesn’t).
Let’s break down three common mistakes that can derail your estate plan—and what you can do right now to make sure your legacy protects the people you love. Estate planning isn’t just about documents. It’s about making sure the people you care about are protected when you’re no longer there to protect them yourself.
Mistake #1: Thinking Your Will Controls Everything
A lot of folks assume once they’ve written a will, their estate plan is set. Unfortunately, that’s not how it works.
Here’s the thing: some of your most valuable assets—like your 401(k), life insurance, or that joint bank account you opened to make life easier—completely bypass your will.
Quick story:
I worked with someone whose mom had a joint account with her oldest son. When she passed, that account became his—legally. Even though the will said everything should be split equally among her kids, that account wasn’t even part of the estate.
They never saw it coming. But the will wasn’t the issue. It was how the account was titled.
What to do instead:
Make a full list of every account, property, and asset you own. Then look at how each one is owned and who the listed beneficiaries are. Your will is just one part of the puzzle—ownership and beneficiary designations often matter a lot more.
Mistake #2: Forgetting ERISA and the Remarriage Rules
This one catches people off guard all the time. If you’ve got a 401(k) or similar company plan, federal law (ERISA) says your spouse automatically inherits it—even if you listed your kids as beneficiaries.
What you can do:
If you’ve remarried and want someone other than your current spouse to inherit your 401(k), you need a signed, notarized waiver from your spouse. Or—and I often recommend this—you roll that 401(k) into an IRA, which gives you more flexibility on beneficiaries.
Just remember: this isn’t just a formality. It’s federal law.
Mistake #3: Assuming Your Heirs Will Make Smart Choices
Let’s say you’ve dotted every “i” and crossed every “t.” Your documents are in place. Your accounts are aligned. Great!
But… now the money’s in the hands of your heirs. And that’s where things can get shaky.
Here’s the hard part no one likes to talk about:
Most inheritances are spent within 12 to 18 months. Not because people are bad—because they’re overwhelmed.
Maybe they buy a Tesla, quit their job, try to “flip houses,” or lend it to a friend who never pays them back. I’ve watched inheritances become a source of guilt or family tension when the recipient wasn’t ready for the responsibility.
Here’s what I tell clients: A will passes on your wealth. A conversation passes on your wisdom.
You’ve got to do both.
What you can do:
- Start talking. Not just about what people will get, but why. What do you want the money to do?
- Consider using a trust—not as a control tool, but as a way to add structure and protection.
- Introduce your heirs to your financial planner. Help them build a relationship with someone who can guide them long after you’re gone.
And if that feels awkward, you’re not alone. Most families never talk about money. But the ones who do? Their legacies tend to last.
Estate Planning Checklist: What to Review Today
Here’s a quick list you can use as a starting point:
- Go through all your accounts and check the ownership titles
- Review beneficiary designations on every policy or retirement plan
- If you’ve remarried, look into ERISA spousal waivers
- Consider using a trust to structure distributions
- Have at least one open conversation with your heirs
- Bring in a professional—even just for a review
And one more tip that I always suggest is to store your documents somewhere easy to access. We create a “Family Estate Organizer” for our clients which holds every important document (more than just financials). Don’t make your family dig through file cabinets or shoeboxes.
Your legacy is more than a balance sheet. It’s how your values live on when you’re not around to explain them.
The technical side of estate planning—wills, trusts, taxes—that’s important. But just as important is the emotional side: the conversations, the context, the clarity.
If you want to make sure your wealth actually helps the people you love—not just funds a few bad decisions—plan beyond the paperwork.
Let’s talk about how to do that.
Reach out to schedule a legacy planning session.
We’ll look at your documents, sure—but more importantly, we’ll talk about the life you want them to protect.
