This article is part of the LifePlan Legal AZ “Planning That Prevents Conflict” series, created to help Arizona families make thoughtful decisions today that reduce stress, confusion, and conflict tomorrow.
Imagine sitting in our office to create your estate plan.
You have talked about your home, retirement accounts, children, and the people you want to protect. You have made thoughtful decisions about who should inherit your assets and how those assets should be managed.
Then we ask one simple question:
“Who would you like to serve as your successor trustee?”
Suddenly, the conversation slows down.
One spouse quickly says, “Our oldest child.”
The other pauses.
Some parents answer, “Probably all three of our children. That seems fair.”
Others admit, “We have no idea.”
That moment reveals something important. Most people spend far more time deciding what their children will inherit than deciding who will be responsible for carrying out those wishes.
Yet the second decision may have a greater effect on whether the family remains close after the parents are gone.
Choosing a trustee is not about rewarding your favorite child. It is not about honoring birth order or avoiding hurt feelings.
It is about selecting the person best prepared to carry out your wishes while helping preserve the relationships that matter most to you.
That is why learning how to choose a trustee deserves more thought than many families initially realize.
Why Your Choice of Trustee Matters So Much
A trustee may be asked to step into the middle of one of the most emotional periods your family will ever experience.
Your loved ones may be grieving. They may be worried about money, uncertain about your instructions, or struggling with old family dynamics.
During that time, the trustee may need to:
- Locate and protect trust assets
- Manage bank, investment, and real estate matters
- Pay appropriate debts and expenses
- Communicate with beneficiaries
- Work with attorneys, accountants, and financial professionals
- Keep records and provide information
- Make decisions about distributions
- Follow the instructions contained in your trust
In Arizona, a trustee who accepts the role must administer the trust in good faith, follow its terms and purposes, act in the interests of the beneficiaries, and comply with applicable trustee duties.
That means the job requires more than being a good person.
It requires judgment, organization, patience, communication, and the ability to make difficult decisions during an emotional time.
A thoughtful trustee can bring clarity and stability to the administration process.
The wrong trustee can unintentionally create delays, suspicion, resentment, and lasting family conflict.

What Does a Successor Trustee Actually Do?
When you create a revocable living trust, you will commonly serve as your own trustee while you are living and able to manage your affairs.
Your successor trustee is the person or organization named to step in when you can no longer serve, whether because of incapacity, death, resignation, or another circumstance described in the trust.
The successor trustee does not get to replace your wishes with their own.
Their role is to understand the trust, follow its instructions, protect the trust property, and treat the beneficiaries appropriately under the terms of the plan.
Depending on the circumstances, a successor trustee may need to:
- Determine what property belongs to the trust
- Secure homes, vehicles, valuables, and financial accounts
- Coordinate appraisals or property sales
- Manage investments and cash needs
- Address taxes, expenses, and creditor issues
- Keep beneficiaries reasonably informed
- Handle disputes or difficult requests
- Distribute property at the appropriate time
- Continue managing protected inheritances for younger or vulnerable beneficiaries
This can be a real job—not an honorary title.
That is why the best trustee is not automatically the person you love most. It is the person most capable of handling the responsibilities you are giving them.

Six Common Mistakes When Choosing a Trustee
1. Choosing the Oldest Child Simply Because They Are the Oldest
One of the most common answers we hear is:
“We will name our oldest child.”
For some families, the oldest child is an excellent choice.
They may be dependable, organized, calm under pressure, and respected by their siblings.
But birth order alone does not make someone qualified to serve as trustee.
Your oldest child may be wonderful, loving, and successful while still being a poor fit for the job. They may dislike paperwork, avoid conflict, struggle to communicate, or feel overwhelmed by financial responsibilities.
Meanwhile, a younger child may naturally be the person everyone calls when something needs to get done.
The right question is not:
“Who was born first?”
It is:
“Who is most likely to carry out our instructions carefully, communicate clearly, and handle pressure responsibly?”
Experience, temperament, and ability matter more than birth order.
2. Choosing the Child Who Lives Closest
Parents also commonly select the child who lives nearby.
Location can be helpful. A local trustee may be able to check on a home, meet with professionals, organize personal belongings, or respond quickly when something needs attention.
But physical proximity is only one factor.
Today, many trust administration tasks can be handled remotely. Financial accounts, documents, meetings, and communications are often managed electronically.
A child who lives in Arizona but is disorganized or difficult to reach may be a worse choice than a dependable child living in another state.
The closer child may also already be carrying much of the caregiving burden. Naming that person as trustee could add another major responsibility at the exact moment they are exhausted or grieving.
Ask whether the person is capable and willing—not merely whether they are nearby.
3. Choosing the Most Financially Successful Child
Parents sometimes assume the child with the strongest career or highest income should manage the trust.
Financial experience can certainly be useful.
But personal success does not automatically make someone a strong fiduciary.
A trustee does not need to personally know everything about taxes, investments, real estate, or legal administration. Good trustees recognize when they need help and are willing to work with qualified professionals.
A financially successful child may be extremely busy, unavailable, impatient, or uncomfortable communicating with siblings.
Meanwhile, a child with a more modest career may be honest, methodical, responsive, and excellent at keeping everyone informed.
You are not choosing the person with the most impressive résumé.
You are choosing the person best equipped to carry out your particular plan.
4. Naming All the Children as Co-Trustees Because It Feels Fair
This is one of the most common arrangements parents suggest—and one we generally approach with great caution.
The reasoning is understandable:
“We love all of our children equally, so we should put all of them in charge.”
Unfortunately, equal authority does not always produce equal harmony.
Co-trustees may need to coordinate decisions involving:
- Investment management
- Property repairs or sales
- Payment of expenses
- Hiring professionals
- Beneficiary distributions
- Tax filings
- Valuation of personal property
- Interpretation of trust instructions
Even responsible siblings can have different communication styles, risk tolerances, schedules, and ideas about what Mom or Dad would have wanted.
One trustee may want to sell the family home quickly.
Another may want to keep it for a year.
One may want to distribute money as soon as possible.
Another may insist on waiting until every possible expense has been resolved.
One may answer messages immediately.
Another may take two weeks to respond.
Arizona law generally allows co-trustees who cannot reach a unanimous decision to act by majority decision. But that does not eliminate the practical problems created by disagreement—especially when there are only two co-trustees or when the trust itself establishes different decision-making rules.
A two-person arrangement can be especially difficult. If the co-trustees disagree, there may be no natural tie-breaker.
Even when a majority can act, being repeatedly outvoted can deepen resentment and create questions about whether everyone is being treated fairly.
Common Mistake
Parents often name all their children as co-trustees because it feels fair. What begins as an effort to keep the peace can instead create delays, deadlock, and frustration when several people must manage important decisions together.
There are situations in which co-trustees can work. The individuals may have complementary skills, communicate exceptionally well, and understand exactly how responsibilities will be divided.
But co-trustees should be selected because the arrangement improves administration—not because parents are afraid someone will feel left out.
The role of trustee is a responsibility, not a prize.
As we discussed in Equal Isn’t Always Fair, treating children identically is not always the best way to protect family relationships.
5. Choosing Someone to Avoid Hurt Feelings
Many parents know which child would do the best job.
They hesitate because they are worried another child will be offended.
That concern is understandable. Parents do not want their estate plan to appear to rank their children or suggest that one child is more loved than another.
But selecting a trustee is not a judgment about who is the best child.
It is a decision about who is best suited for a particular job.
You would not necessarily choose the same child to:
- Repair your home
- Provide medical care
- Prepare a tax return
- Manage a family business
- Plan a large family event
Each responsibility calls for different strengths.
The same is true of trusteeship.
Choosing a trustee solely to protect feelings today can create far greater hurt after death if administration becomes disorganized, secretive, delayed, or adversarial.
Choose based on the needs of the trust and the abilities of the person—not on who may be most offended.
6. Naming Someone Without Asking Them First
Serving as trustee can require substantial time, emotional energy, and responsibility.
Do not assume the person you select will automatically accept.
Before naming someone, have a straightforward conversation.
Explain:
- Why you are considering them
- What the trust is intended to accomplish
- Who the beneficiaries will be
- Whether family conflict may be likely
- Whether the trust may continue for many years
- What professional support will be available
Give them permission to decline.
A reluctant trustee who feels pressured into serving may procrastinate, withdraw, or struggle to make necessary decisions.
It is much better to discover now that your first choice does not want the role than to have your family learn that during a crisis.
You should also name one or more backups in case your first choice dies, becomes incapacitated, resigns, or is otherwise unable or unwilling to serve.
What Makes a Great Trustee?
No trustee is perfect, and the ideal qualities will vary depending on your family and the complexity of your plan.
However, strong trustees commonly share several characteristics.
Honesty and Integrity
A trustee controls property for the benefit of others. Trustworthiness is not optional.
The person should be willing to follow your instructions even when doing so is inconvenient or unpopular.
Organization
Trust administration can involve deadlines, account statements, tax documents, receipts, beneficiary communications, and professional meetings.
A person who regularly loses paperwork, ignores messages, or misses deadlines may struggle in this role.
Good Communication
Beneficiaries are often less suspicious when they receive timely, clear information.
A trustee should be able to explain what is happening, respond appropriately to questions, and keep people informed without becoming defensive.
In Arizona, trustees generally have duties to keep qualified beneficiaries reasonably informed about trust administration and material facts necessary to protect their interests.
Calmness Under Pressure
Trustees may face grief, impatient beneficiaries, property problems, financial uncertainty, and family accusations.
The person should be able to remain steady when emotions rise.
Fair-Minded Judgment
A trustee should be able to separate personal feelings from the instructions in the trust.
They should not use the role to settle old scores, reward allies, or punish difficult family members.
Willingness to Ask for Help
A good trustee does not need to be an attorney, accountant, investment advisor, and real estate professional all at once.
They should know what they do not know and be willing to seek qualified guidance.
Availability
The person needs enough time and capacity to handle the responsibility.
Someone may have all the right skills but still be the wrong choice if they are overwhelmed by work, health concerns, caregiving, or other commitments.
Ability to Say No
Beneficiaries may ask for early distributions, special treatment, loans, personal property, or exceptions to your instructions.
A trustee must be able to make thoughtful decisions and say no when necessary.
Respect From the Family
The trustee does not need to be everyone’s favorite person.
But the administration may be smoother if beneficiaries generally view the trustee as credible, responsible, and honest.
For additional guidance, read How to Choose a Successor Trustee and What to Do Before Naming a Family Member or Friend as Trustee.
Should Your Trustee Be a Family Member or Friend?
A family member or trusted friend can be an excellent trustee.
They may understand your values, know your beneficiaries, and appreciate the history behind your decisions.
They may also be more flexible and personally invested than an institution.
However, familiarity can create complications.
A family trustee may:
- Become caught between competing siblings
- Have personal interests that overlap with beneficiary interests
- Struggle to remain neutral
- Feel guilty enforcing protective trust provisions
- Lack time or administrative experience
- Become the target of resentment
This does not mean family members should be avoided.
It means the choice should be made with open eyes.
Consider the emotional role the person already holds within the family. Then consider what serving as trustee could do to that relationship.
When a Professional Trustee May Be the Better Choice
Sometimes the best way to protect family relationships is to avoid placing one family member in charge of everyone else.
A professional trustee or fiduciary may be worth considering when:
- Siblings have a history of serious conflict
- The estate includes complex or valuable assets
- There is a blended family
- A trust will continue for many years
- A beneficiary has special needs
- A beneficiary struggles with addiction or financial instability
- No family member is willing or able to serve
- The trustee may need to make unpopular distribution decisions
- Neutrality is more important than family familiarity
A professional may bring experience, systems, neutrality, and continuity to the role.
Professional service also comes with fees. Arizona law generally permits reasonable trustee compensation when the trust does not specify a different arrangement.
The question is not simply whether a professional trustee costs money.
The better question is whether professional administration could prevent greater costs caused by delay, mistakes, conflict, or litigation.
Arizona maintains a licensing program and public directory for professional fiduciaries. Banks and trust companies may also offer trustee services, often subject to their own minimum asset requirements and fee schedules.
This topic deserves a more detailed discussion, so we will address how to find and evaluate a professional trustee in a separate article within our trustee resource series.
Should You Name a Professional and a Family Member Together?
Some parents like the idea of pairing a professional trustee with a family member.
The family member may understand relationships, history, and personal preferences. The professional may bring experience, neutrality, and administrative structure.
In the right circumstances, that combination can be useful.
It can also recreate many of the difficulties associated with co-trustees.
Questions may arise about:
- Who has authority over which decisions
- Whether both signatures are required
- What happens when they disagree
- How compensation is divided
- Who communicates with beneficiaries
A combined arrangement should be carefully designed rather than casually added because it sounds like a compromise.
Your estate planning attorney can help clarify responsibilities and determine whether a single trustee, co-trustees, a trust protector, or another structure better fits your goals.
Should You Tell Your Children Who You Chose?
There is no universal answer.
Some families benefit from open conversations. Others may create unnecessary tension by sharing too much detail.
However, surprises often create suspicion.
If one child expects to be trustee and later discovers that a sibling was selected instead, they may interpret the decision as favoritism, punishment, or evidence of outside influence.
When appropriate, consider telling your children:
- Who you selected
- That trusteeship is a responsibility rather than a reward
- Why that person’s skills fit the role
- That your choice does not reflect how much you love each child
- What you expect regarding communication and cooperation
You do not necessarily need to disclose account values or every distribution provision.
The goal is not to invite the family to vote on your plan.
The goal is to reduce confusion and help your children understand that the decision was thoughtful and intentional.
In some families, a written explanation may be more effective than a large family meeting. In others, a carefully planned conversation may prevent years of resentment.
Discuss the best communication approach with your attorney, particularly if your family has strained relationships, unequal inheritances, blended-family concerns, or a beneficiary who may react strongly.
Do Not Forget to Review Your Trustee Choice
The person who was a good choice ten years ago may not be the right choice today.
Review your trustee selection when:
- Your chosen trustee moves, becomes ill, or experiences major life changes
- Your relationship with that person changes
- Your children mature and develop different skills
- Your estate becomes more complicated
- Your family experiences conflict, divorce, addiction, or estrangement
- Your chosen trustee no longer wants the role
- You move to Arizona from another state
- You amend or restate your trust
Your trustee selection should grow with your family and your plan.
A regular estate plan review can help confirm that your documents still name the right people and reflect your current wishes.
Jake’s Observation
If you are struggling to choose a trustee, do not ask:
“Who would be least offended?”
Ask:
“Who would do the best job carrying out my wishes while preserving my family’s relationships?”
Those are often two very different people.
A Practical Trustee Selection Checklist
Before finalizing your decision, ask yourself:
- Does this person understand and respect my wishes?
- Are they honest and dependable?
- Are they organized enough to handle records and deadlines?
- Will they communicate openly with beneficiaries?
- Can they remain calm during conflict?
- Can they make difficult or unpopular decisions?
- Will they ask attorneys, accountants, and advisors for help?
- Do they have enough time to serve?
- Are there personal conflicts that could affect their judgment?
- Have I asked whether they are willing to accept the role?
- Have I named a capable backup?
- Would a neutral professional better protect my family?
If several answers make you uncomfortable, that does not mean your family has failed.
It means your plan may benefit from a different trustee, a professional fiduciary, clearer instructions, or additional safeguards.
Final Thoughts
Parents often spend months deciding who should inherit the family home.
They may spend only a few minutes deciding who will be responsible for managing everything.
Yet the second decision often has the greater impact on whether the family stays together.
Your trustee will not simply manage accounts and sign documents.
That person may become the central point of communication during grief, uncertainty, and major financial decisions.
Choose someone because they have the temperament, integrity, availability, and judgment to perform the job well.
Do not choose them simply because they are the oldest, live nearby, earn the most, or may feel offended if someone else is selected.
And do not assume naming everyone together will automatically keep the peace.
The best estate plans reflect real family dynamics—not idealized versions of how everyone might behave later.
