The Most Overlooked Estate Planning Mistake: Your Beneficiaries
04/01/2026
When people think about estate planning, they usually think about wills and trusts.
But in reality, one of the most important decisions you’ll ever make might be a form you filled out years ago and haven’t looked at since: your beneficiary designations.
Your beneficiaries override your will and trust.
Assets like retirement accounts, life insurance policies and brokerage accounts do not follow your will or trust. They instead go directly to whoever is listed as the beneficiary on file.
That means you can have a perfectly drafted trust, a detailed will, and clear intentions, but none of it matters if the beneficiary isn’t listed or is listed incorrectly.
Below are real-life mistakes I’ve seen people make that can lead to unintended consequences and can leave families in financially vulnerable situations.
1. The Trust That Never Gets Funded
Someone sets up a trust but never lists it as a beneficiary.
Result:
The account bypasses the trust entirely
The trust can’t control or protect those assets
The entire purpose of the trust may be defeated
2. The Ex-Spouse Problem
Someone gets divorced, remarries and builds a new life. BUT they never update their beneficiaries.
Result:
The ex-spouse might still be legally entitled to the account
The current spouse and kids may get nothing from that asset
And yes, this can happen even if the will says otherwise.
3. “I Thought My Will Covered That”
Many people assume their will controls everything. It doesn’t. If your IRA says “John” is the beneficiary, then John gets it no matter what your will says.
A Simple Fix Many People Ignore
The good news is that this is easy to fix. Take 15 minutes and review:
Retirement accounts
Life insurance policies
Brokerage and bank accounts
Ask yourself:
Are the right people listed?
Do the percentages make sense?
Should a trust be listed instead?
If anything has changed in your life (marriage, divorce, kids, a new trust), this should be updated.
Summary
Estate planning isn’t just about documents. It’s about making sure everything works together. And many times, the piece that breaks the plan is the one people forget to check.
Your beneficiaries.
