What happens when my disabled child turns 18 in Tennessee?

At 18, your child becomes a legal adult, and your automatic authority as a parent ends — even if their disability means they can't manage medical, financial, or benefits decisions on their own. Two things shift: under federal privacy law you lose the automatic right to their medical information (a provider can still share with you in some situations, like your child's non-objection or an emergency, but it's now the provider's call), and, as a matter of state law, your child — not you — is now the one who consents to their own care. Your child can also sign contracts or leases. In Tennessee, the tool that restores a parent's authority when their adult child can't exercise it is called a conservatorship.

What is the difference between guardianship and conservatorship in Tennessee?

In Tennessee, conservatorship is for adults and guardianship is for minors — the reverse of how some other states use the words. What many national resources call "guardianship of an adult with a disability" is, in Tennessee, a conservatorship. Guardianship in Tennessee applies only to children under 18. In one narrow situation the two connect: if a court had already found a minor to be disabled and appointed a guardian on that basis, that guardian can continue as conservator when the child turns 18 — but that is a specific exception, not the general rule.

Does conservatorship take away all of my child's rights?

No. Tennessee law requires the court to remove only the specific rights your child truly cannot exercise, and to use the least restrictive option that still protects them. The court order lists exactly which decisions move to you; every right not listed stays with your child. A conservatorship can be limited to just medical and residential decisions, or just finances, and it can be narrowed or ended later as circumstances change.

Do I need a doctor's report to file for conservatorship in Tennessee?

Yes — a sworn report from a physician, psychologist, or senior psychological examiner is required, describing your child's condition and whether a conservator is needed. Importantly, you do not need a willing treating doctor first: if your child hasn't been examined recently, can't get to an appointment, or refuses to be examined, the court can order the examination and appoint the examiner.

Are there alternatives to conservatorship in Tennessee?

Often, yes — and Tennessee's least-restrictive-alternative standard means a conservatorship should reach no further than a person's situation requires. Lighter options include supported decision-making, a durable or health-care power of attorney (if your child can understand and sign one), a health-care surrogate for medical decisions (which a provider can recognize without a court when your child lacks capacity and has no health-care agent), a Social Security representative payee to manage benefit checks, and a special-needs trust. Conservatorship is usually the right tool only when your child cannot sign valid documents and needs an authorized decision-maker for medical, residential, and financial matters.

Do I need conservatorship for my child with autism?

Not always. Many autistic young adults are well served by lighter tools — a power of attorney, a representative payee, or supported decision-making — and don't need a court to remove any rights. Conservatorship fits when your child cannot understand or sign those documents and needs someone with legal authority to consent to medical care, manage benefits, and make residential decisions. It depends on your child's specific abilities and needs.

When should I start the conservatorship process before my child turns 18?

A good rule of thumb is to start several months before the 18th birthday. In Tennessee, IEP transition planning begins early — a transition plan is added by age 14 — so it's natural to raise conservatorship during those transition years rather than waiting for the birthday. The court process takes time, and beginning early means the authority is in place close to when you'll actually need it, rather than scrambling after a medical or benefits issue arises.

Adult Conservatorship

When your child turns 18 in Tennessee, they become a legal adult, and you lose the automatic authority to make their medical, residential, and benefits decisions. Conservatorship (what some states call guardianship of an adult) can restore it. Tennessee law requires the court to remove only the rights your child truly can't exercise, and lighter alternatives are sometimes enough.

Overview

If you are reading this because your child’s eighteenth birthday is coming — or has just passed — you have probably run into something that feels wrong. Your child has a disability. You have made their medical and daily decisions their whole life. And now a doctor’s office, or a benefits office, or the school, is telling you that you no longer have the authority to do that, because your child is a legal adult. Often someone — a doctor’s office, the school, a benefits worker — has already told you that you “need a conservatorship,” without much explanation of what that is or why.

That is a real shock, and it deserves a plain answer: at 18, the law treats your child as an adult who makes their own decisions, and your automatic authority as a parent ends. It does not matter that the disability is lifelong, or that everyone involved knows your child cannot manage those decisions alone. The authority does not transfer to you on its own. It has to be re-established through a court.

In Tennessee, the legal tool that re-establishes that authority for an adult is called a conservatorship. This is where families often get confused, because most national resources use the opposite word. In Tennessee, what other states call “guardianship” of an adult is called conservatorship. Guardianship in Tennessee applies only to minors — children 17 and under. So if you have been searching for “guardianship” of your adult child and coming up short, you are looking for the right thing under the wrong name. (There are narrow bridges between the two for families who already have a minor guardianship: if a court had already found your child to be disabled and appointed a guardian on that basis, that guardian can carry over as conservator at 18; and an existing guardianship of a minor’s estate can, in some cases, be continued for a limited period past 18. Those are specific situations, not the usual path — worth asking about if one fits your family.)

Adult conservatorship is one of the seven areas the firm handles. Michael works with families at exactly this moment — a young adult with a disability, often autism, aging out of the world of IEPs and pediatricians and into a system that suddenly asks who has the legal authority to help.

When your child turns 18

The eighteenth birthday is a single line the law draws, and everything shifts across it at once. The plain rule is this: at eighteen your child is emancipated, and without a conservatorship a parent — or any other caretaking adult — loses decision-making authority in all respects. Where it’s appropriate, a court can leave your child’s own decision-making in place in some domains; but nothing is preserved for you automatically. Understanding what actually changes helps the moment feel less like a trapdoor and more like a set of specific problems, each of which has a solution.

Here is what changes the day your child turns 18, if nothing else is in place:

Medical information and consent. Two separate things change at 18, and they come from different bodies of law. First, access to information: under federal privacy law you lose the automatic right you had as a parent to your child’s medical records — not an absolute lockout (a provider can still share with you when your child agrees or doesn’t object, when your child can’t participate and the provider judges it their best interest, or in an emergency), but it becomes the provider’s call rather than your right. Second, consent to care: your child is now the adult who decides on their own treatment. That is a matter of state law, not the privacy rule — and where your child genuinely can’t make and communicate their own medical decisions, the gap is exactly what a conservatorship fills. Between the two, the clinicians you’ve worked with for years may tell you they can no longer deal with you the way they used to. This is often the first wall a family hits.
Where your child lives and how they are cared for. Decisions about residential placement, day programs, and care arrangements are legally your adult child’s to make, not yours.
Contracts, leases, and signatures. Your child can now enter contracts, sign leases, and make agreements — including ones they may not understand.
Benefits and finances. You can no longer apply for or manage your child’s public benefits or handle their money on their own authority.
Education records. Rights that belonged to you as the parent transfer to the student at 18, including access to and decisions about education records.

None of this means the system thinks your child is fine on their own. It is simply how the law treats the age of majority — the same rule that applies to every 18-year-old. It does not feel like it should work this way when your child has a significant disability, and that reaction is fair. The point of a conservatorship is to close the gap the law opened, and to do it in a way a court keeps carefully limited.

What a conservatorship does and doesn’t do

This is the part most families most need to hear, so it comes before the how-to. A Tennessee conservatorship is not a switch that shuts off your adult child’s entire legal life. It is a specific, court-defined list of decisions that move to you — and nothing more than that.

Tennessee law puts an affirmative duty on the court to remove only the rights your child genuinely cannot exercise, and to use the least restrictive arrangement that still protects them. The court’s order has to spell out, in writing, exactly which powers pass to the conservator. Anything the order does not specifically remove, your child keeps and exercises like any other adult. If your child can make some decisions but not others, the conservatorship is supposed to reach only the ones they can’t.

In practice that means a conservatorship can be narrow. It might cover only medical and residential decisions. It might cover only finances. It might be full in one area and limited in another. The default the law prefers is the limited version, and the court is required to justify anything broader.

There is also a genuinely high bar to appointing a conservator at all. Before the court removes any right, it has to be persuaded by clear and convincing evidence — a demanding standard, well above the everyday “more likely than not” — both that your child has a disability and that they actually need the court’s help. A diagnosis by itself is not enough; the question is not the label but whether your child needs assistance. And a conservatorship is not necessarily permanent. The court can narrow it or end it later, rights can be restored as circumstances change, and your child can ask the court to revisit it at any time.

The plain version: Tennessee treats a conservatorship as a scalpel the court is legally required to keep as small as possible, not a blanket that covers everything.

How the Tennessee process works

It helps to see the court process for what it is: a set of safeguards built around your child, not a set of hoops built to trip up a parent. Every step exists because the court is being asked to remove an adult’s rights, and it is supposed to be careful about that. Here is the shape of it:

The petition. The case begins with a sworn petition, filed in the chancery or probate court of the Tennessee county where your child lives — Michael handles these matters in counties across Tennessee; for Nashville families, that court is in Davidson County. It describes your child, the nature of the disability, who is proposed to serve as conservator and why, the closest relatives, and the facts showing help is needed.
The examiner’s report. A sworn report is required from a physician or, where appropriate, a psychologist or senior psychological examiner. It describes your child’s condition and gives an opinion, with reasons, on whether a conservator is needed. This report carries real weight with the court unless someone contests it.
The hearing. After notice goes to your child and close family, the court holds a hearing, at which your child has the right to attend, to present evidence, and to be heard. The court then decides, under the clear-and-convincing standard, whether to appoint a conservator and over what.

One point removes a fear that stops many families before they start. Parents often assume they need a cooperative treating doctor to sign off first — “our doctor won’t sign anything,” or “my child won’t go to the appointment.” That is not how it works. If your child hasn’t been examined recently, can’t get out to be examined, or refuses to be examined, the court can order the examination and appoint the examiner itself. You do not have to arrive with a willing professional already lined up.

Two things about timing and permanence. On timing: this takes a while, so it is worth starting roughly six months before the eighteenth birthday — often during the transition-planning stage of your child’s IEP — rather than scrambling after a medical or benefits problem forces the issue. On permanence: the oversight continues. Where property is involved the conservator generally reports to the court on the finances, though the court can reduce or excuse that where there is little or nothing to account for. But every year, the court receives a report on your child’s condition and whether the conservatorship is still needed — that annual check-in is required and does not go away. The court keeps watching, year over year, whether the arrangement is still the right one.

Most of these cases are not dramatic. When the family agrees and the need is clear, the process is careful and orderly rather than a fight. A conservatorship can also be contested — most often in a dispute within a family — in which case it becomes a genuinely adversarial matter that has to be litigated.

Benefits, TennCare and records

For a lot of families, the concrete reason to pursue a conservatorship is access — to medical information and to benefits. Both of those close at 18, and a conservatorship reopens them.

Medical information and consent. A conservatorship restores two things at once: your legal authority to receive your child’s medical information (clearing the privacy-rule barrier), and your authority to consent to their care when your child can’t make those decisions themselves.
Public benefits. It gives you authority to apply for and maintain your child’s benefits — TennCare, Medicaid and Medicare, SSI, and Social Security — including handling redeterminations and the interaction between benefits and any assets.
Managing benefit funds. Where there is money to manage, a conservatorship can also give you the authority to handle it, often coordinated with a special-needs trust so that means-tested eligibility is preserved.

One honest note so you don’t do more than you need. If the only issue is receiving and managing your child’s Social Security or SSI check, you may not need a conservatorship at all — the Social Security Administration can appoint you as a representative payee, without a court and without a lawyer. Conservatorship is the tool for when the authority you need reaches beyond a single benefit stream into medical consent, residential decisions, and other legal and financial acts.

Alternatives to conservatorship

Tennessee’s least-restrictive-alternative standard means the court should impose no more than a person’s situation actually requires — and, in that same spirit, an honest page has to say clearly: many disabled adults do not need a full conservatorship, and some need no conservatorship at all. These are the lighter tools, roughly from least to most restrictive:

Supported decision-making. Your child keeps their legal rights and works with trusted people who help them understand information and make their own decisions. Tennessee recognizes supported decision-making as a least restrictive practice and promotes it through a state-funded resource, though it does not have a formal supported-decision-making agreement on the books the way a few other states do.
Powers of attorney. An adult who can understand and sign one can name someone to handle finances (a durable power of attorney) or health care (a health-care power of attorney with an advance directive). The catch is capacity: these require your child to be able to understand and sign the document, which is often not possible for someone with a significant lifelong disability who never had legal capacity to sign — which is precisely why conservatorship exists for that situation.
Health-care surrogate. For medical decisions specifically, Tennessee law lets a provider recognize a family member as a health-care surrogate when an adult lacks the capacity to make their own care decisions and hasn’t appointed a health-care agent — without a court. It is narrower than a conservatorship (it reaches medical decisions, not finances, residence, or benefits), and it depends on the provider recognizing you, but for a family whose only real need is being able to make health-care decisions it can be enough on its own.
Representative payee. For managing Social Security or SSI funds specifically, the Social Security Administration can name you as representative payee — no court, no lawyer. It covers the benefit check and nothing more.
Special-needs trust. Holds assets for your child without disqualifying them from means-tested benefits. It usually works alongside a representative payee or a conservatorship rather than replacing either.

The honest hinge is this. If your child can understand and sign a power of attorney, or if the only need is managing a benefit check, the lighter tools usually do the job and no one should ask a court to remove rights. Conservatorship is the right tool when your child cannot sign valid documents and does need an authorized decision-maker for medical care, where they live, their benefits, and their finances — the situation many families face as a young adult with a significant developmental disability ages out of the school system.

How this connects to special education

If you have spent years in IEP meetings, you already know a version of the idea at the center of this page. In special education, the standard is the least restrictive environment — support your child in the most typical setting that works for them. Conservatorship law uses a close cousin of that idea, the least restrictive alternative — remove no more of your child’s independence than their situation actually requires. It is the same instinct, one life stage later.

That overlap is not a coincidence: a family reaching the conservatorship question at 18 is often the same kind of family the special-education system was serving a few years earlier. In Tennessee, IEP transition planning starts early — a transition plan is added by age 14 — so the conservatorship question naturally comes up during those transition years, well before the eighteenth birthday. It is worth raising it there rather than scrambling after the birthday forces the issue. You can read more about the firm’s special-education and autism advocacy work here:

Michael’s work on behalf of children and families with disabilities is part of that same thread. He represented the student in Sophie G. v. Wilson County Schools before the U.S. Court of Appeals for the Sixth Circuit in 2018 — a disability-discrimination appeal for an elementary-school child with autism, decided in the family’s favor. And in 2025 he was named Lawyer of the Year by the Autism Law Summit. Prior results do not guarantee a similar outcome.

In Michael’s experience, Tennessee courts take parents’ needs in these matters seriously. There is some administrative inconvenience along the way, but the process is relatively efficient — and at the end of it, the family has secured the very thing they were worried about.
