Being named a trustee is an honor. It means someone trusted you enough to put you in charge of protecting assets and caring for the people they love most. But for most first-time trustees, the role comes with a steep learning curve and a set of legal obligations that are easy to underestimate. Mistakes made early in the process can lead to family conflict, personal liability, and costly court battles.
The M Firm works with trustees across the Dallas-Fort Worth metroplex to help them understand their responsibilities under Texas law and avoid the missteps that trip up even the most well-intentioned individuals. We explore the seven most common mistakes new trustees make and what you can do to stay on the right side of your duties.
Mistake #1: Not Reading the Trust Document Carefully
The trust document is your rulebook. It tells you who the beneficiaries are, what they are entitled to receive, when distributions should be made, and how assets should be managed. Many new trustees skim it or set it aside, assuming they will figure things out as they go. This is a costly approach.
The trust’s terms control nearly every decision you make, and acting outside those terms, even with good intentions, can expose you to personal liability.
Mistake #2: Misunderstanding Your Fiduciary Duty
A trustee is a fiduciary, which means you are legally required to act in the best interests of the beneficiaries, not in your own or in the creator’s interests. Many new trustees blur this line without realizing it. The Texas Trust Code requires trustees to act with loyalty, prudence, and impartiality.
The following actions are all violations of that duty and can result in serious legal consequences:
- Self-dealing, such as using trust assets for your own benefit
- Playing favorites among beneficiaries when the trust requires equal or impartial treatment
- Making decisions that personally benefit you at the expense of the beneficiaries
When in doubt, ask yourself whether every decision you make serves the beneficiaries first. If the answer is anything other than yes, stop and get legal guidance before moving forward.
Mistake #3: Failing to Keep Accurate Records
From the moment you take over as trustee, every financial transaction involving the trust needs to be documented. Beneficiaries have the right to request an account, and if your records are incomplete or disorganized, you may find yourself unable to justify decisions you made months or years earlier. Poor record-keeping is one of the leading causes of trustee disputes.
At a minimum, your records should track:
- Income received by the trust
- Expenses paid on behalf of the trust
- Distributions made to beneficiaries
- Investment decisions and the reasoning behind them
Keeping organized, up-to-date records from day one protects you as much as it protects the beneficiaries. It also makes the eventual wind-down of the trust significantly smoother for everyone involved.
Mistake #4: Commingling Trust Assets With Personal Funds
This is one of the most serious errors a trustee can make, and it happens more often than you might expect. Trust assets must be kept entirely separate from your personal finances. That means a separate bank account, separate investment accounts, and separate records. Mixing funds, even temporarily and even with the intent to sort it out later, is a breach of fiduciary duty under Texas law.
Example scenario:
A trustee receives a trust distribution of $15,000 and deposits it into a personal checking account, planning to transfer it to the correct account the following week. In the meantime, personal bills are paid from that same account. Even if the trustee later transfers the correct amount, the commingling has already occurred.
A beneficiary or court could challenge every transaction from that period, and the trustee may have no clean way to prove which funds were personal and which belonged to the trust. What started as a minor convenience becomes a serious legal problem.
Mistake #5: Poor Communication With Beneficiaries
Beneficiaries are entitled to information about the trust and its administration. When trustees go silent, beneficiaries often assume the worst, and disputes follow quickly. Keeping beneficiaries reasonably informed about the trust’s financial status, significant decisions, and expected timelines goes a long way toward maintaining trust and reducing the risk of litigation.
Texas law imposes specific notice and reporting requirements on trustees, and failing to comply is not a minor oversight.
Mistake #6: Delaying Action at the Start
The period immediately after assuming the role of trustee is one of the most time-sensitive. Assets need to be secured, financial institutions need to be notified, beneficiary notices may need to go out, and tax deadlines may already be approaching.
New trustees often delay these steps because they feel overwhelmed or uncertain. That delay can compound quickly. Deadlines are missed, assets go unprotected, and what could have been a straightforward administration becomes complicated and expensive.
Mistake #7: Trying to Do It All Without Professional Help
Many new trustees assume they can handle the role on their own, especially if the trust seems straightforward. In reality, trust administration involves legal requirements, tax filings, investment decisions, and ongoing compliance with the Texas Trust Code.
Trying to navigate all of that without guidance from an attorney and, where appropriate, a financial advisor or accountant, puts you at significant risk. The cost of professional help is almost always far less than the cost of fixing a mistake made without it.
