To apply for legal guardianship, you file a petition in the probate or family court in the county where the proposed ward lives, notify their close relatives, submit medical evidence of incapacity (for an adult), and appear at a hearing where a judge decides whether to appoint you. The process usually takes several weeks to a few months. Emergency guardianships can be granted in 24 to 72 hours when someone faces immediate harm.
Before you file anything, work through the steps below in order. Skipping the groundwork is the fastest way to have a petition denied or dismissed.
Rule Out Less Restrictive Alternatives First
Most courts expect you to show that guardianship is the least restrictive option available. A judge who believes a simpler arrangement would protect the person can deny the petition outright.
A durable power of attorney is the most common alternative. If the person still has the mental capacity to sign legal documents, they can designate someone to handle financial decisions, healthcare decisions, or both, and they keep the right to revoke it. The catch: the person must be competent when they sign, so this isn’t available once capacity is gone.
Other options worth checking before you petition:
- Supported decision-making agreements, recognized in a growing number of states, where a person with a disability chooses trusted supporters to help them understand decisions while keeping the final say themselves.
- Representative payee status through the Social Security Administration, which lets you manage a person’s Social Security or SSI without going to court. It gives no authority over other income or medical decisions.
- A special needs trust or living trust, useful when the concern is financial management rather than personal care.
- Joint bank accounts or authorized signers, which may be enough if the person mainly needs help paying bills.
If none of these will adequately protect the person, because capacity is already lost, they refuse to cooperate, or the risks require court-enforced authority, guardianship is the right path.
Decide Which Type of Guardianship to Request
The type you apply for shapes the forms you file and the evidence you need.
Guardian of the Person, Guardian of the Estate, or Both
A guardian of the person makes decisions about where the ward lives, what medical treatment they receive, and their general welfare. A guardian of the estate manages bank accounts, pays bills, invests assets, and files tax returns. You can petition for one or both. Courts sometimes split the two roles when the person best suited to daily care isn’t the right fit for financial management.
Full, Limited, or Temporary
A limited guardianship restricts your authority to the specific areas where the ward needs help. Courts increasingly favor limited arrangements because they preserve as much of the ward’s independence as possible. Temporary or emergency guardianship is for crises, when someone faces immediate harm and no one is authorized to act; these appointments are typically limited to 60 to 90 days, after which a full hearing must take place.
Minor vs. Adult
Guardianship of a minor usually arises when parents have died, are incarcerated, or otherwise cannot care for the child. Guardianship of an adult requires proving incapacity: that the person cannot adequately provide for their own food, clothing, shelter, physical health, or financial affairs because of a physical or mental condition. The evidentiary bar for adult guardianship is substantially higher and almost always requires medical documentation from one or more physicians.
Gather the Documents You’ll Need
Assemble everything before you start filling out court forms. The specifics vary by jurisdiction, but the core is consistent.
Identifying Information
You’ll need the full legal names, current addresses, and dates of birth for yourself (the petitioner) and the proposed ward. You’ll also need a list of the ward’s closest living relatives, typically spouse, parents, adult children, and siblings, with their addresses. Those relatives must be notified of the proceeding and given a chance to object or offer themselves as an alternative.
Medical Evidence of Incapacity
For adult guardianship, this is the most important piece. Most courts require a written evaluation from a licensed physician documenting the proposed ward’s condition and explaining why they cannot manage their own affairs. Some jurisdictions require evaluations from two medical professionals, and the examinations often must have been conducted within 30 days of filing. The evaluation typically needs to address specific functional limitations, not just a diagnosis, but how the condition prevents informed decisions about care or finances.
A vague report will stall your petition. Judges take the removal of an adult’s rights seriously, and “my mother has dementia” without clinical documentation won’t carry the day.
Financial Information
If you’re seeking guardianship of the estate, you’ll need an estimate of the ward’s personal property, real estate, bank accounts, investments, income sources such as Social Security, pensions, or rental income, and any debts. This information goes into the petition and later forms the basis of the formal inventory you’ll file after appointment.
The Petition Form
The central document is the Petition for Appointment of Guardian. Most courts make it available on the county probate court’s website or through the clerk’s office. It asks why guardianship is necessary, what type of authority you’re requesting, and why you’re the right person for the role. If the case involves a minor, many jurisdictions also require a declaration under the Uniform Child Custody Jurisdiction and Enforcement Act, which discloses any other pending custody or guardianship cases involving the child.
Accuracy here matters more than people realize. An incomplete petition that omits a known relative or misstates the ward’s assets can get your case dismissed, or give an objecting party ammunition to challenge your fitness to serve.
File the Petition and Serve Notice
File the petition with the probate or family court in the county where the proposed ward lives. Filing fees vary widely, ranging from under $100 to over $400. If you can’t afford the fee, most courts have a process for requesting a waiver based on financial hardship.
After filing, the proposed ward and their close relatives must receive formal notice. The proposed ward must typically be personally served, meaning a sheriff, constable, or private process server physically hands them the petition and hearing summons. Relatives can usually be notified by certified mail. Service must happen a minimum number of days before the hearing, commonly 14 days, though this varies, and you’ll need to file proof of service with the court.
The Court’s Investigation and Hearing
The court doesn’t just take your word for it. A judge will typically appoint a guardian ad litem, an independent attorney whose job is to investigate the situation and report back on whether guardianship is truly in the proposed ward’s best interest. The guardian ad litem interviews the proposed ward, the petitioner, and sometimes other family members or caregivers, then files a written recommendation. This person is not your advocate; they work for the judge.
In many jurisdictions, the court also appoints a separate attorney to represent the proposed ward’s expressed wishes, which may differ from what the guardian ad litem recommends. The cost of the guardian ad litem typically falls on the petitioner or the ward’s estate.
At the hearing, you present your evidence: the medical evaluations, testimony about the ward’s condition and needs, and your qualifications to serve. Family members or other interested parties can raise objections, whether about the need for guardianship, the scope of authority requested, or your fitness. If nobody objects and the evidence is clear, hearings can be brief. Contested cases can stretch across multiple court dates.
If the judge approves the petition, the court issues an order of appointment and Letters of Guardianship, sometimes called Letters of Office. That document is your proof of authority, needed for everything from accessing the ward’s bank accounts to making medical decisions on their behalf.
Who Courts Will Appoint
Courts have discretion to appoint anyone they believe will serve the ward’s best interests, but they typically follow a priority order that favors family members. Spouses, parents, and adult children generally rank highest, followed by other relatives and then close friends or professional guardians.
Most jurisdictions disqualify people with certain felony convictions, particularly for offenses involving fraud, theft, or abuse. Many courts require a criminal background check as part of the petition process, and some require an affidavit confirming no pending criminal charges. Being a minor, having been previously removed as a guardian, or having a significant conflict of interest with the ward can also disqualify you.
If you’re appointed guardian of the estate, expect the court to require a surety bond. Courts generally set the bond amount based on the total value of the ward’s personal property plus anticipated annual income. The annual premium typically runs between 0.5% and 3% of the bond amount for applicants with good credit, though it can be higher.
What Happens After Appointment
Getting appointed is the beginning, not the end. Guardianship is a court-supervised role, and failing to meet your obligations can result in removal, personal liability, and in extreme cases, criminal charges.
Within the first 60 to 90 days (the exact deadline varies), a guardian of the estate must file a detailed inventory of the ward’s assets with the court, covering bank accounts, investments, real property, vehicles, and other valuables. You should also notify the IRS of your fiduciary relationship by filing Form 56, which authorizes you to handle the ward’s tax matters and directs IRS correspondence to you.1Internal Revenue Service. Instructions for Form 56
A guardian of the person is generally required to file an annual report on the ward’s personal status, covering where they live, their health, any significant changes, and whether the guardianship remains necessary. A guardian of the estate must file an annual accounting showing every dollar received and spent and the current value of all assets, and should retain supporting records for at least three years. Keep the ward’s assets separate from your own; self-dealing of any kind can lead to removal and personal liability.
You are also responsible for preparing and filing the ward’s tax returns. You sign the return in the ward’s name, adding your title as “Guardian” or “Conservator” beneath your signature.2Internal Revenue Service. Return Signature and Fiduciary Responsibilities If the guardianship estate itself generates income, you may also need to file a separate fiduciary return.
Ending or Changing the Guardianship
Guardianship doesn’t have to be permanent. The most common reasons it ends are the ward’s death, a minor reaching the age of majority, or a court finding that the ward has regained capacity. The process isn’t automatic; someone has to ask the court to act. If a ward’s condition improves, they or someone on their behalf can petition to terminate or modify the guardianship, and the court will typically order an updated medical evaluation before ruling. Your obligation to the court continues until you are formally discharged, and most jurisdictions require a final accounting even after the ward dies.
