Avoiding Common Estate Planning Mistakes That Cost Families Millions

A family gathers closely to review their estate plan, emphasizing the importance of avoiding costly mistakes, as guided by Antoinette M. Solomon, Esq.

Estate planning isn’t just for the ultra-wealthy—it’s for anyone who wants to protect their assets and ensure their family isn’t caught in financial or legal chaos after they’re gone. Yet, even well-intentioned plans can go wrong, costing families millions in taxes, legal fees, and lost wealth.

Here are the costliest estate planning mistakes and how to avoid them.

1. Failing to Fund a Trust (The "Empty Trust" Trap)

   
   

Many people set up revocable living trusts to avoid probate, but they forget one crucial step: actually, transferring assets into the trust.

• If your house, investment accounts, or business aren’t legally titled in the trust’s name, they may still have to go through probate.

• This can cause delays, legal disputes, and unnecessary court costs—defeating the entire purpose of the trust.

  
  

💡 Fix It: Regularly review ownership and beneficiary designations with an estate attorney to ensure assets are correctly titled.

2. Naming the Wrong Beneficiaries (or Forgetting to Update Them)

Outdated or incorrect beneficiary designations are one of the easiest ways families lose money.

• Ex-spouses, estranged relatives, or deceased individuals often remain on life insurance policies and retirement accounts.

• Assets with named beneficiaries bypass your will, meaning a mistake here overrides your entire estate plan.

• Naming a minor child as a direct beneficiary can lead to court-appointed guardianship battles.

  
  

💡 Fix It: Review and update beneficiary designations annually and after any major life event (marriage, divorce, birth of a child).

3. Overlooking Tax Planning (Losing Millions to the IRS)

Many families lose wealth to avoidable estate taxes, capital gains taxes, and income taxes due to poor planning.

• If an estate exceeds the federal estate tax exemption ($13.61 million per person in 2024), heirs could owe 40% in federal estate taxes.

• Passing highly appreciated assets without using a step-up in basis strategy could cost heirs hundreds of thousands in capital gains taxes.

• Life insurance payouts can be subject to estate tax if not structured correctly in an irrevocable life insurance trust (ILIT).

  
  

💡 Fix It: Work with an estate planning attorney and tax advisor to structure your estate for tax efficiency, including using trusts, gifting strategies, and charitable planning.

4. Choosing the Wrong Executor or Trustee (Family Feuds & Legal Battles)

Many people name a family member as executor or trustee, assuming they will act fairly—but this often leads to:

• Conflicts of interest when one sibling manages assets for others.

• Legal challenges if beneficiaries disagree on how assets are distributed.

• Delays in administration if the chosen executor is inexperienced or unqualified.

  
  

💡 Fix It: Consider a professional trustee, corporate executor, or co-trustee structure to minimize bias and ensure proper estate administration.

5. Ignoring Business Succession Planning (Losing the Family Business Overnight)

If you own a business and haven’t legally outlined what happens when you retire, become incapacitated, or pass away, your company could:

• Face legal disputes among heirs over ownership rights.

• Be forced to sell assets to cover estate taxes.

• Lose key employees and contracts due to uncertainty.

  
  

💡 Fix It: Implement a Buy-Sell Agreement, operating agreement, or family business trust that clearly outlines ownership transitions and funding mechanisms.

6. Forgetting Digital Assets (Lost Millions in Crypto, Domains & Online Accounts)

With digital wealth on the rise, failing to plan for online financial accounts, cryptocurrency, and intellectual property can lead to:

• Locked accounts and lost funds (especially with crypto, where no password means no access).

• Legal fights over ownership of monetized YouTube channels, NFTs, or digital businesses.

• Brand and business losses if digital properties aren’t transferred properly.

  
  

💡 Fix It: Create a digital asset estate plan that includes:

• A secure list of digital assets and passwords.

• Legal authorizations under state digital asset laws.

• Successor management instructions for digital business properties.

  
  

7. Relying on a DIY Estate Plan (When It Ends Up Costing More in Legal Fees)

Online templates may seem convenient, but they fail to account for individual family dynamics, state laws, and complex assets.

• Improperly worded trusts or wills can lead to expensive probate fights.

• State-specific inheritance laws vary, meaning DIY plans may be invalid in certain jurisdictions.

• Without an estate attorney’s guidance, you miss out on advanced strategies that could save your family hundreds of thousands in taxes and legal costs.

  
  

💡 Fix It: Work with a qualified estate attorney to create a customized plan that covers all assets, legal risks, and family goals.
