My Special Needs Child Is Turning 18: A Parent's Guide to Limited Conservatorship in California
If your son or daughter has a developmental disability and their 18th birthday is approaching, you may have already discovered something that surprises most parents: the day your child turns 18, the law treats them as an adult — no matter their disability. Doctors can stop talking to you. The school district can transfer educational decisions to your child. Banks, benefits offices, and hospitals can decline to deal with you at all.
For many Riverside County families, the answer is a limited conservatorship — a court arrangement designed specifically for adults with developmental disabilities. This guide walks through what it is, when to start, what forms are involved, what it costs, and the alternatives a judge will expect you to have considered.

What Actually Changes at 18
- Medical: privacy laws mean providers no longer need to share information with you or accept your consent for treatment.
- Education: rights under your child’s IEP transfer to your child at 18.
- Money and contracts: an 18-year-old can sign contracts, open accounts, and be targeted by anyone with a form and an agenda.
- Benefits: SSI and other programs deal with the adult (or a representative payee) — not automatically with a parent.
None of this depends on whether your child can actually understand a medical form or a contract. Without a court order or another legal arrangement, your authority ends.
What Is a Limited Conservatorship?
A limited conservatorship is a California probate-court arrangement for adults with developmental disabilities (generally, people eligible for regional center services — autism, intellectual disability, cerebral palsy, epilepsy, and related conditions that began before age 18). A judge appoints a person — usually a parent — as limited conservator.
It is called “limited” on purpose: unlike a general conservatorship, your adult child keeps every legal right the court does not specifically grant to you. The court can grant up to seven powers, and only the ones you show are needed:
- Decide where your child lives
- Access their confidential records and papers
- Consent (or withhold consent) to marriage
- Control their right to enter contracts
- Give or withhold consent to medical treatment
- Make decisions about their social and personal relationships
- Make decisions about their education
Most families request only the powers they genuinely need — commonly medical, residence, and education. Our limited conservatorship service page describes the process we handle.
The Timeline: Start Before the 18th Birthday
The court process takes months, not weeks. Families who start early — many begin the paperwork around six months before the birthday — can have the hearing land close to when their child turns 18, so there’s no long gap with no one authorized to act.
The process, step by step:
- File the petition with the probate division of the Riverside County Superior Court, along with several supporting forms (listed below).
- The regional center reports. The court notifies the regional center (for Riverside County families, the Inland Regional Center), which prepares a written assessment of your child and the powers requested.
- Your child gets their own attorney. In a limited conservatorship the court appoints an attorney to represent your adult child’s interests.
- A court investigator reviews the case and reports to the judge.
- The hearing. Your child attends. If the judge grants the petition, the court issues an order and then Letters of Conservatorship — the document you’ll actually show to doctors, schools, and agencies.
The Forms Involved
A limited conservatorship petition is a stack of Judicial Council forms. We maintain plain-English guides to each, with current downloadable copies:
- Form GC-310 — Petition for Appointment of Probate Conservator (the main petition; the limited conservatorship boxes are checked here)
- Form GC-312 — Confidential Supplemental Information
- Form GC-314 — Confidential Conservator Screening Form
- Form GC-020 — Notice of Hearing and GC-020(MA) — Proof of Service by Mail
- Form GC-320 — Citation for Conservatorship
- Form GC-335 — Capacity Declaration (needed if you request exclusive medical authority)
- Form GC-348 — Duties of Conservator
- Form GC-340 — Order Appointing Probate Conservator and Form GC-350 — Letters of Conservatorship
Riverside County also uses local forms and probate rules; part of what we do is keep the packet complete and current so it isn’t bounced by the probate examiner. For the full filing walkthrough, see our step-by-step Riverside County conservatorship guide.
Alternatives the Court Expects You to Consider
California law has moved toward less-restrictive alternatives, and judges now expect petitions to address why alternatives aren’t enough. Depending on your child’s abilities, these can include:
- Supported Decision-Making: a written agreement where your adult child chooses trusted supporters to help them understand and make their own decisions — now recognized in California law.
- Powers of attorney and an advance health care directive, if your child has the capacity to sign them.
- A representative payee for Social Security/SSI — which often removes any need for a conservatorship of the estate at all.
- HIPAA releases and school consents for narrower situations.
For some families an alternative genuinely fits better; for others, a limited conservatorship is the only arrangement doctors, schools, and courts will all honor. Addressing the alternatives honestly in the petition also makes the hearing go smoother.
What Does It Cost — and Where a Document Preparer Fits
Hiring a law firm for an uncontested limited conservatorship commonly runs several thousand dollars. But in an uncontested case — the usual situation when a parent petitions for a child they’ve cared for all their life — most of the work is document preparation, filing, and service: exactly what a registered Legal Document Assistant does, at a fraction of attorney rates.
We prepare the full petition packet, file it with the Riverside court, handle service and notice, and keep your case on track for the hearing — with a flat fee quoted up front. Court filing fees are separate (fee waivers are available for qualifying families — many SSI households qualify).

Frequently Asked Questions
Can I start the conservatorship process before my child turns 18?
Yes — and you should. The paperwork can be prepared and filed while your child is still 17 so the hearing lands close to the 18th birthday. Starting about six months ahead is a common rule of thumb, since the regional center report, the court investigation, and the hearing date all take time.
Do I need a lawyer for a limited conservatorship in California?
There is no requirement that the petitioner have a lawyer. In an uncontested case, parents often represent themselves, with the court forms prepared and filed by a registered Legal Document Assistant. The court will appoint an attorney for your adult child as part of the process. If the case is contested, talk to an attorney.
Will my child lose all their rights?
No. A limited conservatorship is built to preserve independence: your adult child keeps every right the court does not specifically assign to you, and the judge grants only the powers shown to be necessary — often just medical, residence, and education decisions.
What if my child is not a regional center client?
Limited conservatorships are for adults with developmental disabilities, which in practice tracks regional center eligibility. If your child’s condition isn’t a qualifying developmental disability, the path may be a general probate conservatorship or a less-restrictive alternative instead — the right choice depends on the situation.
How long does a limited conservatorship last?
It doesn’t expire on a set date — it continues while it’s needed, with periodic court reviews. It can be changed or ended by the court if circumstances change.
How much does it cost?
Court filing fees are set by the court (fee waivers are available for qualifying families). Attorney representation commonly costs several thousand dollars; our document-preparation service is a flat fee quoted up front. Call 951-272-5855 for a quote.
