Estate planning isn't glamorous, and most people put it off until something forces their hand — a health scare, the death of a parent, or a letter from the bank. By then, the mistakes are already baked in. Here are the five errors we see most often, and what they actually cost families.
1. Using a DIY Will or Online Template
Online will kits and fill-in-the-blank forms seem like a bargain. They're not. State laws vary significantly in how wills must be signed, witnessed, and notarized. A single procedural error can invalidate the entire document, sending your estate through intestacy laws — meaning the state decides who gets your assets, not you.
We've seen families spend $15,000 or more in probate litigation because a homemade will was ambiguous about who should inherit the family home. The cost of a properly drafted will or trust is a fraction of what a court battle costs.
2. Creating a Trust but Never Funding It
You paid an attorney to draft a beautiful revocable living trust. You signed it, put it in a safe, and felt relieved. But your home is still titled in your name. Your bank accounts are still in your name. When you die, all of those assets go through probate anyway.
A trust only works if your assets are actually inside it. Funding a trust — retitling property, updating account registrations — is the step most people skip, and it's the step that matters most.
3. Forgetting Beneficiary Designations
Retirement accounts, life insurance policies, and annuities pass by beneficiary designation, not by your will or trust. If your ex-spouse is still listed as the beneficiary on your 401(k) from ten years ago, that's who receives the money — regardless of what your current will says.
Review beneficiary designations every time you experience a major life event: marriage, divorce, birth of a child, or death of a named beneficiary.
4. Ignoring Incapacity Planning
Estate planning isn't just about what happens when you die. What happens if you suffer a stroke, develop dementia, or are in a serious accident and can't make decisions for yourself?
Without a durable power of attorney and a healthcare surrogate designation, your family may have to petition the court for guardianship — a process that can take months, cost thousands in legal fees, and strip you of the ability to choose who makes decisions on your behalf.
5. Never Updating the Plan
An estate plan is not a one-and-done document. Life changes — marriages, divorces, births, deaths, buying or selling property, changes in tax law — and your plan needs to change with it. We recommend reviewing your estate plan every two to three years, or immediately after any major life event.
A will written before your second marriage, before your youngest child was born, or before you bought your current home is almost certainly outdated. Outdated plans create exactly the kind of family conflict and legal expense that good planning is supposed to prevent.
The Bottom Line
Estate planning mistakes rarely show up until it's too late to fix them. The good news is that every one of these errors is preventable with a modest investment of time and professional guidance. If you haven't reviewed your plan recently — or if you don't have one at all — now is the time to start.
