Guardianship & Conservatorship

Court Authority to Protect Vulnerable Individuals


Oregon guardianship proceedings grant legal authority to make personal care and welfare decisions for a minor child or an adult who cannot adequately manage those decisions independently. Conservatorship, a distinct legal process, grants authority over financial affairs and asset management. Families in Portland and surrounding communities may need guardianship when a child's parents are unable to care for the child, or when an adult family member suffers from dementia, traumatic brain injury, developmental disability, or other conditions that impair decision-making capacity. Conservatorship becomes relevant when the protected person owns assets, receives income, or requires financial management but cannot handle those responsibilities safely.


Both proceedings require a petition filed in circuit court, a hearing, and ongoing court oversight. Guardianship addresses decisions such as medical treatment, living arrangements, and daily care. Conservatorship involves managing bank accounts, paying bills, filing taxes, and protecting property. Some individuals require both a guardian and a conservator, while others need only one type of protection depending on their specific circumstances.

What Guardianship and Conservatorship Proceedings Involve

The court appoints a guardian or conservator only after determining that the individual lacks capacity to make informed decisions and that less restrictive alternatives have been considered. Medical evaluations, functional assessments, and testimony from healthcare providers document the nature and extent of the incapacity. Petitioners must provide notice to the proposed protected person, interested family members, and sometimes a court visitor who investigates and reports to the judge.


Once appointed, guardians and conservators file periodic reports with the court detailing the protected person's status, services received, living conditions, and expenditures. The court reviews these reports to verify that the guardian or conservator is fulfilling their duties and acting in the protected person's best interests. Guardians must respect the protected person's preferences to the extent possible, involve them in decisions when feasible, and use the least restrictive means necessary to ensure safety and well-being. Conservators must keep accurate financial records, avoid conflicts of interest, and obtain court approval for major transactions such as selling real estate.


Alternatives to guardianship and conservatorship, such as power of attorney, advance directives, representative payee arrangements, or supported decision-making agreements, may be appropriate when the individual retains some capacity or when planning occurs before incapacity arises. Courts prefer these less restrictive options when they adequately protect the individual's interests without removing legal rights.

Questions Families Ask About Guardianship and Conservatorship

Portland-area families managing difficult care and financial situations often need guidance on which legal process applies and what responsibilities follow.


  • What is the difference between guardianship and conservatorship?

    Guardianship grants authority over personal welfare decisions such as medical care, living arrangements, and daily activities. Conservatorship grants authority over financial matters including managing income, paying bills, and protecting assets. A person may need one or both depending on their abilities and circumstances. Courts evaluate each need separately based on evidence of incapacity in that specific area.

  • How does the court decide whether someone needs a guardian or conservator?

    The court requires medical evidence, often including physician evaluations, neuropsychological testing, or functional capacity assessments, demonstrating that the person cannot make informed decisions due to cognitive impairment, mental illness, developmental disability, or physical incapacity. The petitioner must also show that less restrictive alternatives are insufficient to protect the person's welfare or assets.

  • Who can serve as a guardian or conservator?

    Oregon law prioritizes family members and others who have an existing relationship with the protected person, provided they are suitable and willing to serve. The court considers potential conflicts of interest, the proposed fiduciary's ability to fulfill the responsibilities, and the protected person's preference. In some cases, the court appoints a professional fiduciary, particularly when family members disagree or no appropriate family member is available.

  • What ongoing responsibilities does a guardian or conservator have?

    Guardians must ensure the protected person receives appropriate care, make healthcare decisions, arrange suitable living arrangements, and file annual reports with the court. Conservators must manage assets prudently, maintain detailed financial records, file annual accountings with the court, avoid self-dealing, and obtain court approval for certain transactions. Both must act in the protected person's best interests and follow court orders and Oregon statutory requirements.

  • Can guardianship or conservatorship be reversed or modified?

    Yes. If the protected person regains capacity, the guardianship or conservatorship can be terminated. The protected person, family members, or the fiduciary can petition the court for modification or termination based on changed circumstances. Courts may also remove a guardian or conservator who fails to perform their duties, engages in misconduct, or no longer serves the protected person's best interests.
