Guardianship is a state-court appointment that gives a guardian specified decision-making powers after a court finds someone legally incapacitated. For dementia care, a case usually starts with a petition, notice, and capacity evidence, but the exact documents and deadlines depend on the state.
A dementia diagnosis does not automatically justify guardianship. Courts evaluate the person's decision-making ability using medical, psychological, and other evidence, as the U.S. Department of Justice's guardianship overview explains.

What must the court decide?
The central question is whether the person can make the decisions covered by the proposed guardianship. The court examines functional ability, not the diagnosis alone. Evidence may address financial, health, personal, or other decisions at issue. A case generally begins with a petition.
The hearing may include testimony and a written capacity assessment. The person facing guardianship is ordinarily entitled to notice, counsel, participation, evidence challenges, notice of the resulting orders, and an appeal. Filing a petition does not guarantee the requested outcome. The court may grant narrower powers, appoint someone other than the petitioner, or dismiss the case. Guardianship is typically established by clear and convincing evidence.
Which documents should you prepare?
There is no national guardianship packet. State law controls the appointment process, safeguards, and guardian duties, so begin with the current forms and instructions for the state and court handling the case. Create a working file containing: Not every item in the working file will necessarily be filed.
Some materials support testimony or help prove that procedural requirements were followed. Confirm the filing list instead of copying documents used in another state or an older case. Separate court documents from planning documents. A petition asks the court to act; a power of attorney or advance directive records authority or preferences established outside the guardianship case.
- The petition and its filing instructions
- Medical, psychological, and other capacity evidence
- Any written capacity assessment requested by the court
- Hearing and notice papers
- A record of when and how notice was delivered
Which deadlines matter?
Deadlines may run from the filing date, the hearing date, or the date a judge signs an order. Track the triggering event as well as the due date. Include post-appointment reporting because the case does not end when a guardian is named. California illustrates the importance of working backward from the hearing.
The petition and hearing notice generally must reach the proposed conservatee at least 15 days before the hearing, while the investigator's written report is due at least five days before it, under California Probate Code sections 1822–1826. New York uses a different timetable. An Article 81 hearing is set no later than 28 days after the judge signs the order to show cause; after appointment, guardians file a 90-day initial report and an annual accounting each May, according to the New York State Unified Court System's Article 81 guide. Do not apply either example to another jurisdiction. Build a calendar from the applicable state materials and every signed court order, then record who is responsible for each filing or notice.
Can a narrower option solve the problem?
Guardianship should be a last resort because it removes legal rights. The actual problem may require help with one category of decisions rather than broad control over the person's life. Possible alternatives include: Timing matters.
National Institute on Aging guidance on planning after a dementia diagnosis explains that financial directives, including a durable financial power of attorney and living trust, must be made while the person still has legal capacity. A living will records treatment preferences. A durable health-care power of attorney names someone to make health decisions when the person cannot. Review whether existing documents cover the present need before asking a court for broader authority.
- Supported decision-making
- Advance health-care directives
- A durable financial power of attorney
- A living trust
- A representative or benefit payee
Common mistakes and how to prevent them
The most serious errors often come from treating guardianship as automatic or using another family's case as a template. Each error can delay the case, weaken the evidence, or restrict more rights than necessary.
Watch for these mistakes: Before filing, describe the unresolved decision in one sentence and identify the narrowest tool that could address it. Then verify the court packet, notice rules, capacity-evidence requirements, hearing dates, and post-appointment reports for the applicable state.
- Treating a dementia diagnosis as proof of legal incapacity
- Assuming every state uses the same forms or deadlines
- Waiting until capacity is lost before discussing voluntary planning documents
- Requesting full authority without identifying the specific decisions that need help
- Assuming the petitioner will automatically become the guardian
