Power of Attorney vs Guardianship — In Plain Words
This page compares two different ways one person can get legal power to decide for another person. It compares them on five points only: who decides, who creates it, when each starts and ends, how much a court is involved, and whether the person keeps their own legal rights. Federal material from the Consumer Financial Protection Bureau (CFPB) is labeled CFPB. California material and Oklahoma material are kept in separate, labeled sections, because the words and the rules are not the same in every place.
This page is only the comparison. It does not teach how Oklahoma power of attorney law works in detail. For that, see the separate Oklahoma page: Oklahoma Power of Attorney in Plain Words.
Short answer: CFPB — a power of attorney is a legal document that allows someone else to act on your behalf, and you can plan ahead by creating one to appoint a substitute decision-maker, also called an agent. CFPB — a guardian of property is someone the court names to manage money and property for someone else whom the court has found cannot manage it alone. In short, in the CFPB material: the person chooses and creates the power of attorney; a court creates the guardianship by naming the guardian.
General information only — not legal advice. This page was not written by a lawyer.
The two sides, in one or two sentences each
Power of attorney — CFPB: “A power of attorney is a legal document that allows someone else to act on your behalf.” The CFPB guide for agents adds, in its own example wording, that the person who makes the document is called the principal, and the person named to act is called the agent, another name for which is attorney-in-fact.
Court-appointed guardian or conservator — CFPB: “A guardian of property is someone the court names to manage money and property for someone else whom the court has found cannot manage it alone.” The CFPB page for its guides says the court-appointed guardians guide is for people appointed by a court to be guardians of property or conservators, giving them the duty and the power to make financial decisions on someone’s behalf.
The words are not the same in every place — read this first: CFPB says terms can differ, and that in many states a guardian of property may be called a conservator or guardian of estate, and a person under guardianship may be called an incapacitated person, protected person, or ward. California example only: California Courts Self Help uses “conservatorship” for the adult court arrangement and “guardianship” for a child — see the California sections below. Oklahoma example only: Oklahoma Title 30 is titled “Guardian and Ward,” its Act is the Oklahoma Guardianship and Conservatorship Act, and it calls the person a ward — see the Oklahoma sections below. This page prints each source’s own words, attributed to that source, and does not merge them into one set of words for the whole country.
1. Who decides — who holds the decision power
Power of attorney — CFPB: The CFPB guide for agents asks whether the principal can still manage her money and property after signing a power of attorney, and answers: “Yes, as long as she is still able to make decisions.” The CFPB planning page states the same point for a durable financial power of attorney: after signing it, you can still manage your money and property as long as you have the ability to make decisions.
Guardianship — CFPB: The CFPB guide for court-appointed guardians says, in its opening example, that after a hearing the court has named the guardian of property, and “You now have the duty and power to make decisions on Martin’s behalf about some or all of his money and property.” The name Martin is that guide’s own example name. That guide also says to involve the person in decisions as much as possible.
This box is California example only. Source: California Courts Self Help, “Options to help someone with an impairment or disability,” chart.
California example only — that chart describes power of attorney this way: “Person retains decision-making power with the assistance of trusted individuals,” for legal and financial help.
California example only — that chart describes a limited conservatorship this way: “A conservator makes decisions in specific areas where conservatee with a developmental disability is unable.” It describes a general conservatorship this way: “A conservator makes decisions generally, including medical, financial, etc., as outlined in the conservatorship papers.” The word conservatee is California’s word on that chart for the person in a conservatorship.
This box is Oklahoma example only. Source: Oklahoma Statutes, Title 30, section 1-119.
Oklahoma example only — that section states: “A guardian has only those powers over the person or the property of the ward, or both such person and property, as ordered by the court pursuant to this title.” Title 30, section 1-111, defines “Restrictions on the legal capacity of a person to act in his own behalf” as powers of an incapacitated or partially incapacitated person which are assigned to a guardian.
2. Who creates it — the person, or a court
Power of attorney — CFPB: The CFPB “What is a power of attorney” page says: “You can plan ahead by creating a power of attorney to appoint a substitute decision-maker, also called an agent.” The CFPB guide for agents puts it in example form: the principal made a power of attorney to give the agent legal authority to make decisions about her money or property. In the CFPB wording, the arrangement starts with the person’s own document.
Guardianship — CFPB: The CFPB guides page and the CFPB guide for court-appointed guardians both describe the guardian as named or appointed by a court. The CFPB “What is a power of attorney” page states the contrast this way: if you do not create a power of attorney in advance, a friend or family member might have to go to court to have a guardian appointed if you become incapacitated and are no longer able to make decisions for yourself.
This box is California example only. Sources: California Courts Self Help, “Conservatorships” and “Guardianships in California.”
California example only — on conservatorships, that site says a judge could appoint one person to be in charge of both a conservatorship of the person and a conservatorship of the estate, or different people could hold them, and that a judge can only appoint a conservator if it is shown that it is necessary to promote and protect the person’s well-being.
California example only — on guardianships, that site says: “The court orders that an adult (a guardian) other than a child’s parent has the right to make legal decisions in a child’s life and has responsibility for the child’s care,” for a guardianship of the person; and for a guardianship of the estate, “The court orders someone to manage the child’s finances.” That guardianship page is about a child, not an adult.
This box is Oklahoma example only. Source: Oklahoma Statutes, Title 30, sections 1-105, 1-111, and 1-112.
Oklahoma example only — section 1-105 states: “A guardian is a person appointed by the court to take care of the person or property of another.” Section 1-111 states that “Court” means a judge of the district court assigned to hear probate matters, or assigned to the division of the district court designated to exercise probate jurisdiction. Section 1-112 states: “No person, whether a parent or otherwise, has any power as a guardian, except by appointment by a court.” That section adds that the Act is not to be read to limit the parental rights of parents as the natural guardians of their children.
3. When each starts and ends
Power of attorney — CFPB, general points only: The CFPB guide for agents says an agent should understand when the power of attorney becomes effective, and that it may be right away or only when the principal can no longer make her own decisions, as the document states. That guide says the agent’s responsibilities end if the principal revokes the authority, and that the agent’s authority also ends when the principal dies. It adds that if a court names a guardian of property or conservator to act for the principal, the agent’s authority may end, and that the power of attorney document or state laws govern these situations. This page does not state Oklahoma’s own start-and-end rules for a power of attorney; those rules are on the Oklahoma page linked at the top of this page.
Guardianship — CFPB: The CFPB guide for court-appointed guardians says: “Your responsibilities as Martin’s guardian of property last until the court relieves you of your duties. The court may do this because someone else has been appointed, Martin has died, or Martin no longer needs a guardian.” The name Martin is that guide’s own example name.
This box is California example only. Sources: California Courts Self Help, “Guardianships in California” and “Rights of someone in a limited conservatorship (conservatee).”
California example only — the guardianship page, which is about a child, says the court stays involved and supervises the relationship until it ends, either when the child turns 18 years old or when the court orders it ended. It also says that once parents are able to care for their child again, the parent can ask a judge to end the guardianship.
California example only — the limited conservatorship rights page lists, among the rights all conservatees have on that page, the right to ask a judge to end the conservatorship and the right to ask a judge to replace the conservator. This page does not state a California rule for when every conservatorship ends, because the California pages read in full for this page do not state one in that general form.
This box is Oklahoma example only. Source: Oklahoma Statutes, Title 30, sections 4-803 and 4-804.
Oklahoma example only — section 4-803 states that the authority and responsibility of a guardian terminates upon the death of the guardian, conservator, or the ward, upon the determination of incapacity of the guardian or conservator, or upon removal or resignation of the guardian or conservator. It also states that the authority and responsibility of a guardian of a minor also terminates upon the marriage or majority of the ward.
Oklahoma example only — section 4-804 states that the guardian of an incapacitated or partially incapacitated person or minor may be discharged by the court when it appears to the court, on the application of the ward or otherwise, that the guardianship is no longer necessary.
4. Court involvement — none for a power of attorney, a court process for guardianship
Power of attorney — CFPB: The CFPB “What is a power of attorney” page says a power of attorney gives someone else a great deal of authority over your finances without regular oversight. No court appointment is described in the CFPB power of attorney material read for this page.
Guardianship — CFPB: The CFPB guide for court-appointed guardians states a duty to the court in these words: “You are an agent of the court. The court has trusted you. You must report to the court regularly and be ready to answer any questions.” That guide describes the guardian’s responsibility as a double duty, both to the person served and to the court.
This box is California example only. Sources: California Courts Self Help, “Options to help someone with an impairment or disability,” “Introduction to being a conservator,” and “Responsibilities and duties of a limited conservator.”
California example only — the options chart lists oversight for power of attorney as “No automatic oversight,” and oversight for both limited conservatorship and general conservatorship as “Automatic oversight.”
California example only — the conservator pages say conservatorships are reviewed by the court that created the conservatorship, that someone from the Court Investigator’s Office will review the case one year after the conservatorship is granted and then every two years after that, and that the court can also ask for an investigation on its own schedule.
This box is Oklahoma example only. Source: Oklahoma Statutes, Title 30, section 1-114.
Oklahoma example only — section 1-114 states that in all cases the court making the appointment of a guardian has exclusive jurisdiction to control such guardian in the management and disposition of the person and property of the ward. It lists court powers that include appointing and removing guardians for minors and for incapacitated and partially incapacitated persons, issuing and revoking letters of guardianship, and controlling the conduct of guardians with regard to the care and treatment of their wards and the management of their financial resources.
5. Whether the person keeps their own legal rights
Power of attorney — CFPB: The CFPB planning page says you retain the ability to change or cancel a durable financial power of attorney as long as you are still able to make decisions, and that after signing it you can still manage your money and property as long as you have the ability to make decisions. The CFPB guide for agents states the matching point on changing it: the principal can take away, or revoke, the agent’s authority at any time if she wants to and is still able to make decisions.
Guardianship — CFPB: The CFPB guide for court-appointed guardians of property says that guide only covers duties of the guardian of property. It says sometimes a guardian of property is also appointed as guardian of the person, sometimes a different person is appointed to be guardian of the person, or the person himself may still be able to make personal decisions — health care and other personal decisions, in that guide’s words. This page does not turn that passage into a general rule about every right in every guardianship, because the guide states it for that property-guardian context.
This box is California example only. Source: California Courts Self Help, “Rights of someone in a limited conservatorship (conservatee).” This box is about a limited conservatorship, as that page is.
California example only — that page is headed “You do not lose all rights or all voice in important decisions affecting your life.” It says all conservatees on that page have the right to be treated with understanding and respect, the right to have their wishes considered, and the right to be well cared for by their conservators, and also the right to be represented by a lawyer, to ask a judge to replace the conservator, to ask a judge to end the conservatorship, and to make or change a will.
California example only — that page then says: “A limited conservatee maintains all rights that are not specifically given to the limited conservator by the court.” It lists examples of what the conservatee can do unless the court order says different, including deciding where to live, receiving personal mail, voting, marrying or entering into a registered domestic partnership, having visitors, making medical decisions, and receiving and controlling a salary and controlling an allowance. This page prints those examples only as that page’s limited-conservatorship list, not as a list for every conservatorship or every state.
This box is Oklahoma example only. Source: Oklahoma Statutes, Title 30, sections 1-103 and 1-111.
Oklahoma example only — section 1-103 states that it is the purpose of the system of general and limited guardianships for incapacitated and partially incapacitated persons to provide for the participation of such persons, as fully as possible, in the decisions which affect them. It states the Legislature’s intent that the court exercise its authority so as to encourage maximum self-reliance and independence and make orders only to the extent necessitated by the person’s condition.
Oklahoma example only — section 1-111, in defining a partially incapacitated person, states that a finding that an individual is a partially incapacitated person shall not constitute a finding of legal incompetence, that such a person shall be legally competent in all areas other than the area or areas specified by the court in its orders, and that such person shall retain all legal rights and abilities other than those expressly limited or curtailed in those orders.
How the anchors word the court side differently, kept separate: CFPB uses “guardian of property” and “conservator” together for the court-appointed money role, and says the person may be called an incapacitated person, protected person, or ward. California example only: California Courts Self Help calls the adult court arrangement a conservatorship, with a conservator and a conservatee, and uses guardianship for a child, with a guardian. Oklahoma example only: Title 30 calls the person a ward, defines a guardian as a person appointed by the court, and its Act covers both guardianships and conservatorships. This page does not pick one of those word sets and apply it to the others.
A note about USA.gov
USA.gov does not appear to run a covering page that explains power of attorney, or that explains guardianship, or that compares the two. Searches for a USA.gov page on power of attorney or guardianship, made for this page, did not return a USA.gov page covering either topic in that way. The closest USA.gov page read in full for this page is “Find a lawyer for affordable legal aid.” That page lists “adult guardianship” only as one item in a list of family-law issues a person may be able to get help with. It does not explain power of attorney, it does not explain guardianship, and this page does not cite it as covering the comparison. Because of that gap, this page rests on the CFPB, California, and Oklahoma sources listed below.
What this page does not cover
This page does not give any template, and it does not reproduce any form. It gives no fill-in document for a power of attorney, a guardianship, or a conservatorship.
This page does not give instructions presented as sufficient to create a power of attorney, a guardianship, or a conservatorship for any reader. It compares, in the anchors’ own substance, who decides, who creates each arrangement, when each starts and ends, court involvement, and whether the person keeps their own legal rights, with each point attributed to its source and jurisdiction.
This page gives no dollar figures. Where a California page or an Oklahoma section read for this page states a fee, an amount, or a money limit, this page does not print it, because no figure is needed for the comparison.
This page does not teach Oklahoma power of attorney law in detail. Signing rules, durability details, agent duties, and the statutory form for an Oklahoma power of attorney are covered, if at all, only on the Oklahoma page linked at the top of this page, and they are not repeated here.
This page does not cover health care decision documents beyond naming them where an anchor names them, and it does not say what any person should do in their own situation.
Words to know
Power of attorney: CFPB — “A power of attorney is a legal document that allows someone else to act on your behalf.”
Principal: CFPB guide for agents — under a power of attorney, the person who made the document is called the principal.
Agent / attorney-in-fact: CFPB guide for agents — the person named in a power of attorney to act is called the agent; another name for agent is attorney-in-fact.

Guardian of property: CFPB — “A guardian of property is someone the court names to manage money and property for someone else whom the court has found cannot manage it alone.”
Conservator / conservatee: California example only — California Courts Self Help uses conservator for the person a judge appoints in a conservatorship, and conservatee for the person who needs the help. CFPB also uses the word conservator for a court-named role in many states, in the wording in the note box above; the two uses are printed separately and are not merged.
Guardian / ward: Oklahoma example only — Title 30, section 1-105: a guardian is a person appointed by the court to take care of the person or property of another.
