Fiduciary Role Terminology

Fiduciary Role Terminology by State
A companion reference to Professional Fiduciary Licensing by State. Last updated: June 2026.
Using the wrong title for a fiduciary role is not just a labeling error. In some states, the same word means two entirely different things. In Texas, "conservator" is a child-custody term with no connection to fiduciary practice. In California, Connecticut, and Tennessee, "guardian" refers to a role involving minors, not incapacitated adults. A practitioner who reads a court order, a referral, or a statute in an unfamiliar state and assumes the terminology matches their home state can fundamentally misread the scope of the appointment.
This reference maps each of the six professional fiduciary roles to the title each state uses, so a practitioner can identify which role is actually in play, regardless of what it is called.
How to Read This Reference
Of the six roles in the professional fiduciary umbrella, only three vary meaningfully in name from state to state. Those three are mapped in full below. The other three use terminology that is effectively uniform nationally and are covered in a single section rather than repeated across fifty-one near-identical rows.
Roles that vary by state:
-
The personal and medical role for a living protected person (decisions about health, care, and living arrangements)
-
The financial and estate role for a living protected person (managing property, income, and assets)
-
The estate administrator role for a deceased person's estate
Roles with nationally uniform terminology:
-
Trustee, agent under a power of attorney, and representative payee / VA fiduciary
The single most important caution in this area: the same word can mean different things in different states. "Guardian" refers to the personal-care role in most states, but in California, Connecticut, and Tennessee a "guardian" serves a minor and the adult personal-care role is held by a "conservator." "Conservator" usually means the financial role, but in California, Connecticut, and Tennessee it covers the adult role generally, and in Texas "conservator" is a child-custody term with no connection to fiduciary practice at all. Always read the role, not the label.
A second, subtler trap: in several states that use "guardian of the estate" for the involuntary financial role (Arkansas, New Hampshire, New Jersey, Ohio, Oklahoma, Rhode Island, and Wisconsin) the word "conservator" also exists, but it names a different, usually voluntary role: a competent but physically infirm or aged person who petitions the court for help managing their own property. In those states, seeing "conservator" does not mean an incapacity finding was made. The notes column in Table 1 flags each of these.
Table 1: Personal/Medical and Financial/Estate Roles, by State
The two columns that matter most for living protected persons. Where a state uses different vocabulary for minors than for adults, that is noted in the "Minor terminology" column; where the same terms apply to both, the column says "Same."
Table 2: Estate Administrator (Deceased Person's Estate), by State
This is a separate role from the financial role in Table 1. It covers a decedent's estate, not a living protected person's property.
In most states the pattern is the same: the person who settles the estate is an executor when named in a valid will and an administrator when appointed because there is no will, or no named executor able to serve, and a single collective term covers both. What varies is that collective term (usually "personal representative," but "fiduciary," "representative," or the civil-law "succession representative" in some states) and, in Florida and Maryland, the titles themselves: those two states use "personal representative" as the actual title in every case, treating "executor" and "administrator" as superseded.
How to read the columns: "Title with a will" and "Title without a will" give the working titles a fiduciary carries in that state. "Collective term" gives the umbrella word the code uses to refer to both at once.
States That Require Certification
The following states do not operate their own licensing bureau but require a professional guardian or fiduciary to hold a professional certification, in most cases the national credential issued by the Center for Guardianship Certification, before a court will appoint them. The requirement is generally enforced through the appointment petition or a court rule rather than a standalone licensing application.
Oregon
Governing body: Oregon probate court, under ORS 125.240; the Oregon Judicial Department maintains a list of certified individuals provided by the Center for Guardianship Certification
Roles covered: Professional fiduciaries, defined by ORS 125.240 as a person serving at the same time as fiduciary for three or more protected persons who are not related to the fiduciary, in the guardian and conservator roles. The requirement does not apply to a professional fiduciary serving only as trustee or estate administrator.
Key requirements:
-
A petition seeking appointment of a professional fiduciary must include proof that the professional fiduciary, or the individual responsible for making decisions or managing client assets, is certified by the Center for Guardianship Certification as a National Certified Guardian or National Master Guardian
-
Criminal records check (Oregon and, in defined circumstances, national)
-
Disclosure of educational background, professional experience, investment credentials, fees, and any revenue-sharing arrangement
Notes: Oregon requires the national credential by statute and enforces it through the appointment petition rather than a state licensing board. The requirement reaches the guardian and conservator roles; a person may serve as a professional fiduciary in trustee or estate-administration matters without it.

New Mexico
Governing body: New Mexico district court, under NMSA § 45-5-311(D) (guardians) and § 45-5-410(D) (conservators), implemented through New Mexico Supreme Court Rule 1-142
Roles covered: Professional guardians and professional conservators appointed for an incapacitated or protected person
Key requirements:
-
A professional guardian may not serve or be appointed unless certified and in good standing with a national or state organization, recognized by the New Mexico Supreme Court, that provides professional certification for guardians; the same requirement applies to professional conservators
-
The Center for Guardianship Certification is the recognized national certifier
-
Proof of certification filed with the appointing court within the deadlines set by Rule 1-142, and annual proof that the certification remains in good standing
Notes: New Mexico ties eligibility to a recognized professional certification rather than a state licensing bureau, and enforces it by court rule with a continuing annual proof obligation. The list of recognized certifying organizations is set by the New Mexico Supreme Court.

North Dakota
Governing body: North Dakota Supreme Court (Administrative Rule 59), for guardians appointed by a state district court under N.D.C.C. Chapter 30.1-28
Roles covered: Professional guardians, both individuals and entities. Rule 59 also sets qualifications for nonprofessional guardians; emergency guardians appointed under N.D.C.C. 30.1-28-10.1 are exempt.
Key requirements:
-
An individual proposed to serve as a professional guardian must possess certification through the Center for Guardianship Certification
-
Completion of the North Dakota Supreme Court online guardianship training program, with a certificate of completion filed before letters of guardianship are issued
-
A criminal history record check provided to the appointing court before the hearing, unless waived
-
An affidavit disclosing any investigation for theft, fraud, or the abuse, neglect, or exploitation of an adult or child
-
An entity proposed to serve as a professional guardian must be accredited through the Council on Accreditation, or its employed guardians must possess CGC certification, with an affidavit that all employed guardians completed the state training program
Notes: Administrative Rule 59 took effect March 1, 2018, and its requirements must be completed before a court will appoint. North Dakota recently adopted a related Administrative Rule 59.1 establishing an Office of Guardianship and Conservatorship; monitor for expanded oversight.

Pennsylvania
Governing body: Pennsylvania Supreme Court and the Orphans' Court (20 Pa.C.S. § 5511(f); Pennsylvania Orphans' Court Rule 14.6)
Roles covered: Individuals seeking appointment to a third or subsequent active guardianship of an incapacitated person (guardian of the person or of the estate). The threshold is the third active guardianship; a guardian serving one or two incapacitated persons is not required to be certified.
Key requirements:
-
Before a third active guardianship appointment, certification by a national nonprofit guardianship certification organization, which at a minimum requires submission of education and employment history, federal and state criminal history record information, and passage of a national certification exam
-
Proof of the certification provided to the court prior to the third appointment
-
A court may waive the certification on a petition showing equivalent licenses or certifications (for example, health care, social work, or psychology for a guardian of the person; accounting or financial management for a guardian of the estate); a license to practice law does not qualify as an equivalent
Notes: Pennsylvania's certification requirement was added by Act 61 of 2023 and implemented through amendments to the Orphans' Court Rules effective in 2024. It is threshold-based: it attaches at the third active guardianship rather than to all professional guardians. The national certification contemplated by the statute aligns with the Center for Guardianship Certification's national credential.

Idaho
Governing body: Idaho Supreme Court, under Idaho Court Administrative Rule 54.6 (professional guardian and conservator certification); guardianship and conservatorship are governed by Idaho Code Title 15, Chapter 5 (the Uniform Probate Code)
Roles covered: Professional guardians and conservators. ICAR 54.6 defines a professional guardian or conservator as a person who provides guardianship or conservatorship services for a fee, has rendered services for three or more persons, and is not related to the person under guardianship or conservatorship by blood, adoption, marriage, or civil union.
Key requirements:
-
A professional guardian or conservator must be certified by the Center for Guardianship Certification (CGC), unless the court waives the requirement for good cause (ICAR 54.6)
-
If the professional guardian or conservator is an entity, the certification requirement applies to the individuals providing services on its behalf
-
Separately, every individual seeking appointment as any guardian or conservator, professional or not, must file a certificate of completion of the Idaho Supreme Court's online training course before permanent letters are issued; a $25 fee applies and may be waived for good cause (ICAR 54; Idaho Code Section 31-3201G)
-
Standard court oversight applies, including annual reporting (Idaho Code Section 15-5-419)
Notes: Idaho is a certification state for professional fiduciaries. ICAR 54.6 ties the CGC certification requirement to professionals who serve three or more unrelated persons for a fee, the same threshold model used in Oregon. The universal online training requirement under ICAR 54 applies to all proposed guardians and conservators and is distinct from the professional certification requirement; the court may waive either for good cause.

Roles with Nationally Uniform Terminology
These three roles do not vary in name in a way that requires a state-by-state table.
Trustee. A person or institution that administers a trust is a trustee in every state, whether the trust is created during life or under a will. The term is uniform regardless of whether a state has adopted the Uniform Trust Code. The person who creates the trust is the settlor, trustor, or grantor, these vary, but the fiduciary title does not.
Agent under a power of attorney. A person authorized to act under a power of attorney is an agent (the term used by the Uniform Power of Attorney Act) or, in older and still-common usage, an attorney-in-fact. The two terms are interchangeable. The variation is between the modern "agent" and the traditional "attorney-in-fact," not between jurisdictions.
Representative payee and VA fiduciary. These are federal appointments, not state ones, so the terminology is identical nationwide. The representative payee is appointed by the Social Security Administration to manage Social Security or SSI benefits; the VA fiduciary is appointed by the U.S. Department of Veterans Affairs to manage VA benefits. No state vocabulary applies. These are not traditionally classified as professional fiduciary roles, though many professional fiduciaries serve in them.
States That Rely on Court Appointment
The majority of states do not require professional fiduciaries to obtain a separate license before being appointed. In these states, the court is the gatekeeper. Fiduciaries demonstrate their qualifications (background, bonding capacity, relevant experience or credentials, and absence of disqualifying history) directly to the court in the appointment proceeding.
This does not mean that there are no requirements. Courts in appointment-based states routinely expect fiduciaries to demonstrate:
-
Relevant professional background or experience
-
Bondability
-
Clean criminal and financial history
-
Evidence of training or credentialing, particularly the National Certified Guardian designation for guardian and conservator roles
The National Certified Guardian credential carries weight with courts across all states, not only those that formally require it. It signals that a practitioner has met a nationally recognized standard and is serious about the work.
Frequently Asked Questions
What is the difference between a guardian and a conservator?
In most states, a guardian makes personal and medical decisions for an incapacitated adult and a conservator manages that person's finances and property. The terms are not universal, however. In California, Connecticut, and Tennessee, the adult personal-care role is called conservator of the person, and the word guardian is reserved for roles involving minors. In Texas, conservator is a child-custody term with no connection to fiduciary practice. Always confirm what each term means in the specific state where the appointment is made.
Does conservator always mean the financial role?
Not in every state. In most states, conservator refers to the financial and estate management role for a living protected person. But in California, Connecticut, and Tennessee, conservator covers both the personal and financial roles for adults. In several other states, including Arkansas, New Hampshire, New Jersey, Ohio, Oklahoma, Rhode Island, and Wisconsin, the word conservator exists but names a separate, usually voluntary role for a competent person who requests help managing their own property. In those states, seeing the word conservator in a court document does not necessarily mean an incapacity finding was made.
What does conservator mean in Texas?
In Texas, conservator is a child-custody term. It has no connection to fiduciary practice in the guardian, conservator, or estate sense used in other states. A Texas court appoints a guardian of the person for the personal and medical role and a guardian of the estate for the financial role when a protected person is incapacitated.
What is a guardian of the estate?
Guardian of the estate is the term several states use for the financial and property management role for a living protected person, the role most states call conservator. States that use this term include Arkansas, Delaware, Florida, Illinois, Maryland, Nevada, New Hampshire, New Jersey, North Carolina, Ohio, Oklahoma, Pennsylvania, Rhode Island, and Wisconsin. The responsibilities of the role are the same regardless of the label: managing the protected person's income, assets, and property under court oversight.
Is a personal representative the same as an executor?
In most states, personal representative is the collective term that covers both an executor (appointed when there is a valid will naming them) and an administrator (appointed when there is no will or no named executor able to serve). In Florida and Maryland, personal representative is the actual working title in every case, and executor and administrator are treated as superseded terminology. In a few states, including New York, Ohio, Vermont, and New Hampshire, executor and administrator remain the operative titles and personal representative is used only as a general descriptor. The Uniform Probate Code states use personal representative as the formal office of appointment.
What is an estate administrator?
Estate administrator is an umbrella term for the person who settles a deceased person's estate, collecting assets, notifying creditors, and distributing property to beneficiaries. Depending on the state, that person may be called a personal representative, executor, administrator, or in Louisiana a succession representative. The specific title depends on whether there is a will and which state's law governs the estate. Estate administrator is not typically a statutory title in most states but is widely used as a plain-language description of the role.
What is the difference between an agent and an attorney-in-fact?
Agent and attorney-in-fact refer to the same role: a person authorized to act on behalf of another under a power of attorney. Agent is the term used by the Uniform Power of Attorney Act and appears in more recently enacted state statutes. Attorney-in-fact is the traditional term and remains common in practice and in older documents. The two are interchangeable. Neither term means the person is an attorney licensed to practice law.
What is a guardian of the person?
Guardian of the person is the role that carries authority over personal and medical decisions for an incapacitated adult, decisions about health care, living arrangements, and daily care. In most states this role is simply called guardian; the fuller title guardian of the person is used where the state also recognizes a guardian of the estate (the financial role) and needs to distinguish the two. In California, Connecticut, and Tennessee, the equivalent adult personal-care role is called conservator of the person.
Are fiduciary role titles the same in every state?
No. The roles themselves, managing a person's health and care decisions, managing their finances, administering a trust, settling an estate, are consistent across states, but the titles vary. Guardian, conservator, guardian of the person, guardian of the estate, personal representative, executor, and administrator can mean different things depending on the jurisdiction. Trustee, agent under a power of attorney, and representative payee are the roles with essentially uniform terminology nationwide.
A Note on Scope and Reliance
This reference maps statutory terminology as of June 2026 and is reviewed periodically. It is a practitioner reference, not legal advice. Terminology can change when states adopt or amend uniform acts, and courts may use terms informally that differ from the statutory definitions. Confirm the operative terminology with the relevant state's current code before relying on any single entry in a live matter.
For Practitioners Building Across State Lines
Understanding what each role is called in a given state is one dimension of multi-jurisdictional practice. The underlying responsibilities, the decisions, documentation, financial management, and accountability that the work demands, are consistent across state lines even when the terminology is not.
