To get guardianship of a mentally ill relative, you file a petition in the probate or circuit court where your relative lives, back it with a medical evaluation showing their illness prevents them from meeting their own basic needs, and attend a hearing where a judge decides whether to appoint you. The process usually takes several weeks to a few months. Most states now require you to show that less restrictive options won’t work before a judge will grant the appointment, because guardianship removes fundamental rights and courts treat it as a last resort.
Rule Out Less Restrictive Options First
Before you file, honestly evaluate whether a lighter arrangement could protect your relative. The vast majority of states require the court to consider whether the person’s needs could be met without guardianship, and a judge may deny your petition if you skipped this step.
The most common alternative is a power of attorney, where your relative voluntarily authorizes you to handle financial or healthcare decisions. The catch: your relative must have the mental capacity to sign the document when it’s created. If their illness has already progressed past that point, a power of attorney is off the table.
Other options worth checking:
- A healthcare proxy or advance directive your relative may have signed earlier, which can already authorize someone to make medical decisions.
- A representative payee arrangement through the Social Security Administration, which lets someone manage a beneficiary’s Social Security income without a court proceeding. The SSA makes this determination based on medical evidence and statements from people who observe the beneficiary.
- Supported decision-making, which at least 17 states have authorized by statute. The person with a disability chooses trusted supporters to help them understand and make their own decisions, without transferring authority to anyone else.
If none of these tools are workable, either because your relative already lacks the capacity to participate or because you’ve tried them and they’ve failed, document that. A petition that shows what you’ve already attempted carries far more weight than one that jumps straight to guardianship.
What Counts as Legal Incapacity
A guardianship petition requires proving that your relative is legally “incapacitated,” meaning their ability to receive and evaluate information and communicate decisions is impaired to a degree that they cannot manage their financial resources or meet essential requirements for their physical health and safety.1Social Security Administration. SSA POMS GN 00502.300 – Digest of State Guardianship Laws A diagnosis alone doesn’t meet that standard. The court needs evidence that the illness directly prevents your relative from functioning in concrete ways.
The kind of evidence that moves judges includes proof that your relative can’t manage prescribed medications and their health is deteriorating, that they’re living in unsafe or unsanitary conditions, that they can’t understand or pay household bills, or that they’ve become vulnerable to financial exploitation because they can’t recognize scams or resist pressure. Making choices you disagree with doesn’t qualify. The court is looking for an inability to engage in the decision-making process, not bad outcomes from voluntary choices.
Medical evidence is the backbone. Courts rely on formal evaluations from licensed physicians or psychologists, and those evaluations need to go beyond restating a diagnosis. The clinician must describe the functional limitations: how the illness impairs your relative’s ability to understand information, weigh options, and communicate decisions about their care or finances. A report that says “patient has schizophrenia” without describing what the patient can and cannot do is essentially useless.
Mental illness poses a unique challenge because symptoms are often intermittent. Your relative may have lucid periods where they appear capable, making a consistent pattern of incapacity harder to establish.2Special Needs Alliance. Guardianship and Mental Illness Be prepared for the possibility that a single evaluation captures a good day rather than a representative one. Multiple observations over time, documented incidents, and testimony from people who interact with your relative regularly can fill that gap.
Can You Serve as Guardian
Not everyone who wants the role will be approved. Courts prioritize family members and people who have an existing relationship with the proposed ward, but they also screen for factors that make someone unfit. You’ll typically need to disclose felony convictions, and certain criminal histories will disqualify you outright. Specifics vary by jurisdiction, but convictions involving dishonesty, neglect, violence, or crimes against vulnerable people are commonly disqualifying.
Many states require a criminal background check as part of the appointment process, and some also run credit checks for anyone who will manage the ward’s finances. The check itself is modest, generally under $40. Failing to disclose a relevant conviction is a much bigger problem than the conviction itself; judges have discretion to weigh older or less serious offenses against the overall picture, but concealment destroys credibility.
If no suitable family member is available or willing, the court can appoint a professional guardian, whose fees are paid from the ward’s estate. Some jurisdictions run public guardian programs for low-income individuals at no cost to the family.
Documents You Need to File
Gathering the right paperwork before you file saves time and prevents the court from sending you back:
- The petition for guardianship itself, on the court’s form, where you formally request the appointment, identify yourself and your relative, and explain why guardianship is necessary. Most probate and circuit courts publish their version on the local court website.
- A medical evaluation, sometimes called a Physician’s Report or Certificate of Incapacity. Many courts provide a specific form the doctor must complete. It must come from a licensed physician or psychologist, is usually required to be dated within a set window before filing (often 60 to 90 days), and should include a diagnosis, prognosis, and a detailed description of your relative’s functional limitations.
- A list of interested persons: the full names and addresses of your relative’s closest living family members, including spouse, parents, adult children, and siblings. The court requires them to receive formal notice, even if they’ve been absent or uninvolved. If you can’t locate someone, you may need permission to notify them through a published newspaper announcement.
- Personal identification for both petitioner and proposed ward: full legal name, current address, and date of birth.
The petition needs a factual statement explaining exactly why guardianship is required. This is where you connect the medical evidence to your relative’s real-world inability to care for themselves. Vague language like “he can’t take care of himself” won’t cut it. Describe the missed medications, the unpaid rent, the exploitation incident.
Filing Fees and Other Costs
You file the completed petition and medical evaluation with the probate or circuit court in the county where your relative lives. Most courts accept filings in person at the clerk’s office, and some offer electronic filing. The filing fee varies by jurisdiction but generally falls between $200 and $400.
Filing fees are the smallest part of the expense. Attorney fees are typically the largest, often running several thousand dollars for an uncontested case and considerably more if family members object. Even if you file without a lawyer, the court will appoint an independent attorney or guardian ad litem to represent your relative’s interests; those fees are usually paid from the ward’s estate. If the ward has no meaningful assets, some courts absorb the cost or appoint volunteer attorneys.
If the court appoints you as guardian of the estate, meaning you’ll manage your relative’s finances, you may also need a surety bond. The bond protects the ward’s assets by guaranteeing reimbursement if you mismanage funds. The bond amount is typically based on the total value of the ward’s property and expected income, and the annual premium runs roughly 1% to 5% of the bond amount.
After filing, the clerk assigns a case number and schedules a hearing. You’re then responsible for formally serving notice on all the family members you listed. The court doesn’t do this for you, and failing to properly notify a required relative will delay everything.
What Happens at the Hearing
The hearing is where the judge decides whether to grant guardianship. Present will usually be you, your attorney if you have one, your relative, the court-appointed attorney or guardian ad litem, the judge, and any family members who chose to attend after receiving notice.
Your relative has the right to be there, to be represented by an attorney of their choosing, and to contest the guardianship. The court-appointed attorney meets with your relative beforehand, explains their rights, assesses the situation independently, and reports to the judge. That attorney is not on your side. They represent your relative’s expressed wishes, even when those wishes conflict with what you believe is best.
You’ll testify about why guardianship is necessary, and the judge will review the medical evaluation and any other evidence. The court-appointed attorney will present a report that may include a recommendation. The judge weighs everything to answer two questions: has incapacity been proven to the legal standard, and is guardianship in this person’s best interest? If both answers are yes, the judge issues an order specifying the scope of authority granted.
If a Family Member Objects
If another family member opposes the petition, either disputing that guardianship is necessary or arguing they should be the one appointed, the case becomes contested. That changes everything about the timeline and cost. A contested case may involve multiple hearings, competing medical evaluations, witness testimony, and significantly higher attorney fees. Courts often schedule conferences to narrow the disputes before proceeding to a full evidentiary hearing.
Emergency Guardianship for Immediate Danger
When your relative faces immediate danger and the standard process would take too long, most states allow you to petition for emergency or temporary guardianship. These are granted on an expedited basis, sometimes within days, but they’re limited in duration and scope. An emergency guardianship typically lasts only long enough to address the immediate crisis, after which you’ll still need to pursue standard guardianship through the full process. Courts grant these sparingly and only when you can show that waiting would result in serious harm.
Scope of the Order the Judge May Grant
Courts increasingly favor granting only the minimum authority necessary. The order you receive may be a limited guardianship, where the judge specifies exactly which decisions you can make and which rights your relative retains, or a full guardianship where virtually all decision-making authority transfers to you.
A limited guardianship might authorize you to make healthcare decisions and manage finances while leaving your relative free to choose where they live, who they associate with, or whether to vote. Full guardianship is reserved for situations where the person truly cannot participate in any decisions. If you’re seeking guardianship because your relative can’t manage medications and is being financially exploited, but they can still make reasonable choices about their daily routine, expect the court to tailor the order accordingly.
There are also two categories of authority that may be granted separately or together:
- Guardian of the person, who makes decisions about healthcare, housing, and personal welfare.
- Guardian of the estate (sometimes called conservator), who manages the ward’s financial affairs, including property, income, and bills.
You can be appointed to one role without the other. If your relative’s main struggle is financial management but they can still make their own medical decisions with support, the court may appoint you as guardian of the estate only.
Your Responsibilities After Appointment
Being appointed as a guardian creates a fiduciary duty to act in your relative’s best interest, not your own convenience. That means making informed choices about medical treatment, living arrangements, and financial matters while encouraging their participation in decisions to the greatest extent possible. A guardian who isolates the ward from decision-making or treats the appointment as unlimited personal authority is the kind of guardian courts remove.
Courts don’t appoint you and walk away. Most jurisdictions require regular reports, typically annually, describing your relative’s personal status, health, and living situation. If you’re managing finances, you’ll also submit a detailed accounting of every dollar in and out. Courts monitor these filings. If a report is late or incomplete, the clerk will notify you and may escalate to the judge. Persistent failures can lead to removal, contempt proceedings, or appointment of a replacement.
Ongoing obligations also include keeping the ward’s funds completely separate from your own, maintaining records of all transactions, and getting court approval before major decisions like selling the ward’s home or moving them to a different facility. The job is more administrative than most people expect. If you aren’t prepared for the paperwork and oversight, consider whether a professional guardian would be a better fit.
Changing or Ending the Guardianship
Guardianship isn’t necessarily permanent, and that matters for mental illness, where conditions can improve with treatment. If your relative’s capacity improves to where they can manage some or all of their own affairs, either you or your relative can petition the court to modify or terminate the arrangement. The court will typically require updated medical evidence and may appoint a new evaluator.
A guardianship also ends automatically if the ward dies. If you as the guardian become unable or unwilling to continue serving, you can petition the court to resign and have a successor appointed. You can’t simply walk away. Until the court formally releases you or appoints someone else, you remain legally responsible.
If your relative’s condition fluctuates, a modification from full to limited guardianship may be more appropriate than outright termination. The goal at every stage is to impose only as much oversight as the person genuinely needs.
