To get legal guardianship for an adult with dementia, you file a petition in the probate court of the county where the person lives, submit a physician’s evaluation showing they can no longer make their own decisions, notify their close relatives, and persuade a judge at a hearing that no less restrictive option will keep them safe. Uncontested cases usually reach a hearing within 30 to 60 days and cost roughly $2,000 to $5,000 with an attorney. Contested cases run longer and cost far more. Because guardianship removes fundamental rights, courts treat it as a last resort.
When Guardianship Is Actually Warranted
A dementia diagnosis by itself does not qualify someone for guardianship. The legal question is functional: can the person still understand information, appreciate the consequences of their choices, and communicate decisions about their care and money? Courts look at what the person can and cannot do, not at the label on their chart.
The problems that usually push families to file are practical. Bills go unpaid. A parent hands money to a phone scammer. Needed medical treatment gets refused. Basic needs like food and shelter stop being managed. When these patterns create real risk of harm and the person cannot recognize that risk, the legal standard is likely met.
Alternatives a Judge Will Ask About
Courts expect you to have considered less restrictive options first, and the judge will ask what you looked at. The complication is that most of these tools require the person to still have enough capacity to sign, so timing matters after a diagnosis.
Durable Powers of Attorney
A durable power of attorney for finances lets the person name someone to handle bank accounts, bills, investments, and property. “Durable” is the key word: the document stays in force after the person loses capacity, which is when it’s needed. An ordinary power of attorney ends the moment the person becomes incapacitated.
A healthcare power of attorney (sometimes called a healthcare proxy) does the same for medical decisions, letting the agent consent to treatment, choose facilities, and make end-of-life decisions. A living will alongside it, spelling out the person’s wishes about life-sustaining treatment, gives the agent clearer guidance and heads off family conflict.
Revocable Living Trusts
A revocable living trust can protect finances without court involvement. The person moves property into the trust and names a successor trustee who takes over management once they lose capacity. The trust only reaches assets that were formally transferred into it, so anything left out sits outside the trustee’s authority. A trust also does nothing for healthcare decisions, so it works alongside a healthcare power of attorney, not in place of one.
Supported Decision-Making
About a third of states have formally recognized supported decision-making by statute. Rather than transferring authority to someone else, the person picks trusted supporters who help them understand their options and reach their own decisions. The person stays in control; the supporters provide information and guidance. For someone in early-stage dementia who still has meaningful capacity, this preserves far more autonomy than guardianship. It becomes less workable as decline progresses, but it can carry someone through the early and moderate stages.
Limited or Full Guardianship
If guardianship is necessary, the court does not have to grant blanket authority. A limited guardianship narrows the guardian’s powers to specific areas of actual need, such as finances only or medical decisions only, and leaves the person in charge of everything else.1U.S. Department of Justice. Elder Justice Initiative – Guardianship Overview A full (plenary) guardianship gives the guardian decision-making power over almost every personal and financial matter.
Most states now require courts to consider limited guardianship before imposing a full one. If the person can still make reasonable decisions in some areas but not others, requesting a limited order shows the judge you are trying to preserve independence where it exists. That tends to make the petition easier to approve.
What the Petition Requires
The case starts in the probate court (or its equivalent) in the county where the person with dementia lives. The forms vary by jurisdiction, but the information courts require is broadly the same.
Medical Evidence
This is the most important piece. You need a formal evaluation from a licensed physician or psychologist documenting the nature and severity of the cognitive impairment. The report should be functional: can the person manage a checkbook, understand a treatment plan, recognize when someone is taking advantage of them? A one-line letter saying the patient has Alzheimer’s will not carry a petition. Expect to pay $500 to $1,500 for the evaluation.
Information About the Person With Dementia
The petition asks for the person’s full legal name, date of birth, current address, and living situation. It also requires a list of their closest living relatives with contact information, because the court must notify all of them. Missing a relative can delay your case or give someone grounds to challenge the order later.
Information About You
You will supply your own name, address, and relationship to the person. Many courts also require a criminal background check and sometimes a credit report. A felony conviction or history of financial problems is not an automatic bar, but it invites closer scrutiny of whether you are the right choice.
How the Case Moves Through Court
Once the paperwork is complete, the case moves in stages. Uncontested cases generally reach a hearing 30 to 60 days after filing.
Filing and Serving Notice
File the petition with the court clerk and pay the filing fee, typically $100 to several hundred dollars depending on the court. Fee waivers are usually available based on income. After filing, you must formally serve notice on the person with dementia and their close relatives, informing them of the petition and the hearing date. A professional process server usually charges $40 to $200 per person served.
The Guardian Ad Litem
The court appoints an independent person, often an attorney, called a guardian ad litem to represent the interests of the person with dementia. The guardian ad litem meets with the person, reviews the medical evidence, interviews family, and files a report recommending whether guardianship is appropriate and whether you are a good fit. The court may also order its own independent medical examination, separate from the report you filed.
The Hearing
At the hearing, the judge reviews the medical evidence, the guardian ad litem’s report, and any testimony from family or other interested parties. The person with dementia has the right to attend and to have their own attorney. The judge decides two questions: is this person legally incapacitated, and if so, is the proposed guardian the right choice? If both answers are yes, the court issues an order appointing the guardian and setting the scope of the guardian’s authority.
Emergency Guardianship
Sometimes the situation cannot wait a month or two. If the person faces an immediate threat, such as active financial exploitation, a medical crisis with no one authorized to consent to treatment, or abuse or neglect, you can petition for an emergency temporary guardianship. Courts can grant these on an expedited basis, sometimes within days, when a judge finds that waiting for the full process would cause serious harm.
Emergency orders are short by design, generally lasting no more than 60 to 90 days. During that window you must file a standard petition for permanent guardianship, which then proceeds through the normal process. The emergency order is a bridge, not a substitute.
When Relatives Disagree
Guardianship cases turn contentious more often than families expect, especially where siblings disagree about a parent’s care or where a second spouse and adult children from an earlier marriage are already in tension. A contested case is a different animal from the cooperative process.
Once someone formally objects, whether they dispute the need for guardianship or want a different guardian, the proceeding becomes full litigation. Expect evidentiary hearings, witness testimony, competing medical evaluations, and much higher attorney fees. Courts typically follow a statutory priority list among competing petitioners, usually preferring a spouse, then adult children, then other relatives. A judge can deviate from the order for good cause, such as a conflict of interest or a closer relationship with a lower-priority relative.
The person with dementia has the right to express a preference about who serves as guardian, and courts are supposed to weigh it. If they consistently name one family member as someone they trust, that carries real weight even when overall capacity is diminished.
What It Costs
The total depends heavily on whether anyone objects. An uncontested case with an attorney typically runs $2,000 to $5,000 in legal fees, varying by region and complexity. A contested case can easily reach $10,000 and often much more.
Beyond attorney fees, budget for:
- Filing fees of $100 to several hundred dollars, depending on the court
- The capacity evaluation, $500 to $1,500
- Process server fees, $40 to $200 per person served
- Guardian ad litem fees set by the court, which may be paid from the ward’s estate
- A surety bond covering the ward’s assets, with annual premiums based on the estate’s value
Many of these costs, particularly the bond premium and guardian ad litem fees, can often be paid from the ward’s own estate rather than out of pocket, but you should not assume it without asking the court. If the ward has minimal assets, some jurisdictions offer reduced fees or appointed counsel.
What Being Appointed Obligates You To Do
Appointment is the beginning of an ongoing relationship with the court, not the end of the case.
Guardian of the Person
A guardian of the person decides where the ward lives, what medical treatment they receive, and what services and therapies they access. The job is to honor the ward’s known preferences and values wherever possible, not to impose what the guardian thinks is best. If the person always said they wanted to stay in their home as long as possible, the guardian should make a genuine effort to arrange that before considering a facility.
Guardian of the Estate
A guardian of the estate, called a conservator in some states, manages the ward’s finances: paying bills, managing investments, filing tax returns, and protecting assets from waste or exploitation. The guardian cannot use the ward’s money for personal benefit and must keep detailed records of every transaction. Selling major assets like a home, or making large investment changes, generally requires separate court approval. Terminology varies by state, so check whether your jurisdiction calls the financial role “conservator” or folds it into “guardian” before filling out forms.
Reporting to the Court
Guardians must file an initial inventory of the ward’s assets soon after appointment, then submit annual reports covering both the ward’s well-being and a full financial accounting of income and expenditures. Missing these deadlines can get you removed as guardian, so treat them seriously.
Social Security Is a Separate Process
A state court guardianship order does not give you authority over the ward’s Social Security benefits. The Social Security Administration runs its own process and does not recognize state court orders or powers of attorney as controlling federal benefits.2Social Security Administration. Representative Payee Program
If the person receives Social Security retirement, SSDI, or SSI, apply separately to become their representative payee. This means visiting your local Social Security office, completing Form SSA-11, and showing proof of identity. The SSA evaluates whether the beneficiary can manage their own funds and, if not, designates you to receive and manage the payments.2Social Security Administration. Representative Payee Program As payee, you must use the funds for the beneficiary’s current needs and file annual accounting reports with the SSA, separate from the reports going to the guardianship court.
Rights the Ward Still Has
Guardianship restricts rights; it does not erase them. Even under a full guardianship, the ward keeps the right to be treated with dignity, to communicate with family and friends, and to have their preferences considered in decisions about their care.1U.S. Department of Justice. Elder Justice Initiative – Guardianship Overview
Voting rights vary significantly by state. In some, a person under full guardianship automatically loses the right to vote; in others, they keep it unless the court specifically finds they lack the capacity to vote. Under a limited guardianship, the person retains any right the court order does not explicitly remove. That is one of the strongest reasons to request a limited rather than a full guardianship: every right not put at issue stays with the person.
