One of the most important decisions you’ll make in your estate plan is choosing your successor trustee. This person (or institution) will manage your trust when you can’t — including during periods of incapacity and after your death.
Yet many families struggle with this choice. Should it be a family member? A friend? More than one person? When is a professional trustee better? And what exactly does a successor trustee do?
This guide explains everything in clear, simple terms so you can feel confident choosing the right person to protect your family and carry out your wishes.

⭐ What a Successor Trustee Actually Does
A successor trustee steps into your shoes when:
- You become incapacitated, or
- You pass away
Their job is to manage your trust and follow the instructions you’ve written.
✔ During Your Lifetime (If You Become Incapacitated)
If you’re alive but unable to manage your affairs, your successor trustee can:
- Pay bills
- Oversee your home and real estate
- Manage bank and investment accounts
- Provide for your spouse and children
- Work with financial and legal professionals
- Make distributions according to your needs
This avoids court-ordered guardianship, which is public, intrusive, and expensive.
(For more on incapacity planning, see: “The Complete Guide to Creating a Trust for Your Family.”)
✔ After Your Death
Your successor trustee handles:
- Collecting your assets
- Paying valid debts
- Managing or selling property
- Distributing inheritance according to your trust instructions
- Managing funds for your children until the ages you selected
- Filing final tax returns
- Keeping the process private and outside probate
This role is central to the entire estate plan.
⭐ Why the Successor Trustee Matters So Much
Your trust only works as well as the person you choose to run it.
A poorly chosen trustee can:
- Cause family conflict
- Mismanage money
- Delay distributions
- Misinterpret your instructions
- Struggle with bookkeeping or communication
A well-chosen trustee protects your family, your assets, and your legacy.

⭐ Who Should You Choose?
Here are the most common options, with the pros and cons of each.
✔ Option 1: A Responsible Family Member
This is the most common choice.
Pros:
- Knows your family
- Understands your values
- Often willing to serve without pay
- Emotionally aligned with your goals
Cons:
- May feel overwhelmed with responsibilities
- Could face conflict with other beneficiaries
- Might lack financial or legal expertise
Best for: Stable families, straightforward finances, cooperative children/beneficiaries.
✔ Option 2: A Trusted Friend
An unbiased friend can sometimes be the perfect middle ground.
Pros:
- Neutral
- Unbiased
- Emotionally supportive but not entangled in family dynamics
Cons:
- Still a large responsibility
- Limited legal/financial familiarity
- May eventually decline the role
Best for: Anyone uncomfortable choosing between children or relatives.
✔ Option 3: Co-Trustees
Some families choose two people to serve together.
Pros:
- Shared responsibility
- Balanced decision-making
- Built-in accountability
Cons:
- Can cause delays
- Risk of disagreement
- Must coordinate schedules and signatures
Best for: Highly functional families willing to collaborate.
✔ Option 4: A Professional Trustee (Bank, Trust Company, Attorney)
This is increasingly popular, especially for:
- Blended families
- High-value estates
- Complex instructions
- Children with special needs
- Beneficiaries with financial struggles
Pros:
- Neutral and unbiased
- Experienced
- Regulated
- Insured
- Emotionally detached
- Ideal for long-term or complex trusts
Cons:
- Fees apply
- Less personal
Best for: Families who want professionalism and long-term stability.
⭐ What Qualities Matter Most?
When selecting a successor trustee, look for someone who is:
✔ Trustworthy — above all
Money and family dynamics require integrity.
✔ Organized
The job involves paperwork, deadlines, and communication.
✔ Calm under pressure
Difficult times require steady decision-making.
✔ Fair and impartial
They should follow your instructions — not their personal opinions.
✔ Financially responsible
They don’t need to be rich, but they must handle money sensibly.
✔ Good communicator
Beneficiaries rely on clear updates and documentation.
✔ Available
Being a trustee can take months or even years.
⭐ Should You Name Your Children as Trustees?
Many parents default to naming their adult children as successor trustees — this can be fine, but it depends on your family dynamics.
Good candidates:
- Mature
- Responsible
- Neutral
- Not in conflict with siblings
Not ideal:
- Children with substance issues
- Impulsive spenders
- Siblings with long-standing conflict
- Anyone likely to be overwhelmed or emotional
(For family-specific planning, see: “Estate Planning for Blended Families: Avoiding Conflict and Protecting Everyone.”)
⭐ Should You Name More Than One Trustee?
Co-trustees work well when:
- Siblings get along
- Each person brings a skill (e.g., one financial, one emotional)
- Checks and balances are beneficial
However, naming all children often leads to:
- Delays
- Disagreements
- Paperwork requiring multiple signatures
- Potential gridlock
A better option is often:
- One child as trustee
- Another as backup
- Or a professional trustee
⭐ Backup Trustees (Always Required)
Never name only one trustee.
Always list at least:
- 1 primary
- 1 backup
- 1 emergency backup
Life changes — trustees can decline, become ill, move away, or pass away. Backups keep your trust functional.
⭐ Final Thoughts: Your Trustee Choice Shapes Your Family’s Future
Your successor trustee is one of the most important roles in your estate plan.
Choose someone who:
- Understands your values
- Can handle responsibility
- Will honor your wishes
- Can keep peace within the family
A great trustee makes your trust work smoothly.
A poor trustee can undo even the best-drafted plan.
