5 Estate Planning Mistakes That Cost Families Six Figures
The quiet errors that wreck good plans — and how to avoid each one
Estate planning isn't just about documents — it's about coordination across documents, accounts, beneficiaries, and titling. Most plans fall apart not because the will or trust was wrong, but because of small administrative errors that nobody caught. Here are the five estate planning mistakes we see most often, and how to avoid each.
Mistake #1: Outdated beneficiary designations
Beneficiary designations on retirement accounts, life insurance, and bank accounts OVERRIDE your will. If your ex-spouse is still listed as the beneficiary on a 401(k) from 1995, they inherit — regardless of what your current will says.
- ·Audit every account annually: 401(k), IRA, Roth, life insurance, annuities, bank POD, brokerage TOD, HSA
- ·Update after every major life event: marriage, divorce, birth, death of a beneficiary
- ·List PRIMARY and CONTINGENT beneficiaries on every account
- ·Don't list 'my estate' as the beneficiary — forces the account through probate (defeating the point)
Mistake #2: Trust set up but not funded
We see this constantly. A family pays to set up a revocable living trust, then never actually moves their assets into it. The trust exists on paper but owns nothing — so when the person dies, the assets go through probate anyway.
- ·Re-title your home into the trust name (deed transfer)
- ·Re-title bank and brokerage accounts to the trust (or add the trust as POD/TOD)
- ·Update retirement account beneficiary designations to align with trust language (do NOT generally retitle the retirement accounts themselves)
- ·Document everything — a 'trust funding letter' from your attorney helps your trustee later
Mistake #3: Naming a minor child as beneficiary directly
Minors can't legally hold property. If you name a 6-year-old directly on a life insurance policy, the court has to appoint a guardian to manage the money until the child turns 18 — at which point they receive the full balance with zero strings attached. Most families regret this.
- ·Use a trust as the beneficiary, with the minor as the beneficiary of the trust
- ·The trust can hold and distribute funds gradually (e.g., 1/3 at 25, 1/3 at 30, 1/3 at 35)
- ·Designate a successor trustee who's not the same person as the financial guardian — separation of powers
- ·For very small amounts, UTMA accounts work but lock control at 18 or 21
Mistake #4: DIY estate documents from an online template
LegalZoom-style templates work for very simple estates. They fail for anything complex — blended families, business ownership, special needs children, out-of-state property, IRAs with specific beneficiary rules. The cheap template often ends up costing a family far more in probate litigation later than a real estate attorney would have.
- ·Templates miss state-specific provisions (Michigan probate rules differ from Florida)
- ·Trust language often doesn't match how IRA custodians require beneficiaries to be named
- ·Special situations (blended families, business succession) need custom drafting
- ·A properly-drafted estate plan from a Michigan attorney pays for itself many times over for any estate with a home, retirement accounts, or minor children
Mistake #5: Failing to communicate the plan
Estate planning often fails because the family doesn't know what's happening. The executor doesn't know where the will is. The trustee doesn't know they were named. The healthcare proxy doesn't know your wishes. Plans that work require communication.
- ·Have ONE family meeting to walk through the plan at a high level
- ·Document where original documents are stored (fireproof safe, attorney's office, etc.)
- ·Share contact info for your attorney, financial advisor, and CPA
- ·Discuss healthcare wishes BEFORE a crisis, not during one
- ·Re-visit the plan every 3-5 years or after major life events
The Takeaway
Estate plans fail in administration, not in drafting. The will and trust documents are usually fine — but the beneficiary forms, account titles, and family communication are where most plans break. Audit annually, especially after major life events. Coordinate with your attorney + financial advisor as a team, not separately.
