How to Obtain a Limited Conservatorship in California for a Developmentally Disabled Adult

Current as of: September 10, 2026 Guardianship & Conservatorship California

In California, a limited conservatorship allows parents to retain decision-making rights for a developmentally disabled child after they turn 18. Filing Form GC-310 requires a $435 court fee, and the court will grant up to 7 specific powers to protect your child without stripping all their civil rights.

When a child with special needs turns 18 in California, the law automatically recognizes them as a legal adult. This means parents abruptly lose the legal authority to consent to medical treatments, manage Individualized Education Programs (IEPs), or access confidential records. For families of children with developmental disabilities, this transition can be terrifying. Whether you live in Los Angeles, San Diego, or San Francisco, learning how to obtain a limited conservatorship in California is the safest way to ensure your child remains protected.

A general conservatorship strips an individual of almost all their basic rights and is usually reserved for the elderly with severe dementia. In contrast, a limited conservatorship is specifically designed for adults with developmental disabilities. It encourages maximum independence while allowing you to step in only where necessary. If you are approaching your child's 18th birthday, you can find a compassionate special needs attorney in our US Lawyer Directory to help you navigate the local probate courts.

Transitioning at Age 18: Specific Conditions

Under Cal. Prob. Code § 1420, a developmental disability is defined as a disability that originates before an individual turns 18, is expected to continue indefinitely, and constitutes a substantial handicap. Courts handle these cases delicately, acknowledging that no two disabilities are the same.

Autism Spectrum and Intellectual Disabilities

For individuals on the severe end of the Autism Spectrum or those with significant intellectual disabilities, safety and routine are paramount. A limited conservatorship allows parents to prevent their adult child from being taken advantage of financially or socially. You can request powers to manage their living situation, ensuring they reside in a safe environment, and control their access to sensitive contracts that they may not fully understand.

Down Syndrome and Cerebral Palsy

Many young adults with Down Syndrome or Cerebral Palsy are highly social and capable of working or volunteering, but they may still need assistance with complex medical decisions or government benefits. A limited conservatorship can be tailored so that the adult child retains the right to earn and spend their own pocket money or choose their social activities, while the conservator handles major surgical consents and ongoing physical therapy authorizations.

The Role of the California Regional Center

You cannot obtain a limited conservatorship in California without the involvement of a Regional Center. Under Cal. Prob. Code § 1827.5, once you file your petition, the local Regional Center-such as the Frank D. Lanterman Regional Center Los Angeles or the San Diego Regional Center San Diego-must conduct a mandatory assessment of the proposed conservatee. They will evaluate the individual's mental and physical condition, living arrangements, and social needs, and then submit a confidential report to the judge recommending which specific powers should be granted or denied.

The 7 Specific Powers Granted by the Court

Unlike a general conservatorship, a limited conservator is only granted the exact powers requested and approved by the judge under Cal. Prob. Code § 2351.5. There are seven specific powers you can ask for:

  • Residence: The power to decide where the conservatee lives.
  • Confidential Records: The power to access medical, educational, and financial records.
  • Marriage: The power to consent to or withhold consent for marriage.
  • Contracts: The power to enter into binding contracts on their behalf.
  • Medical Decisions: The power to give or withhold medical consent.
  • Social and Sexual Contacts: The power to limit social contacts if someone is preying on or abusing the conservatee.
  • Education: The power to make decisions regarding their education, IEPs, and vocational training.

Timeline for Filing Before the 18th Birthday

Preparation is key. You do not have to wait until your child's 18th birthday to file. It is highly recommended to file the Petition for Appointment of Probate Conservator (Form GC-310) approximately 3 to 6 months before they turn 18. This allows the court to appoint a public defender for your child, schedule the Regional Center assessment, and send a court investigator to your home. If timed correctly, the judge can sign the order exactly on or shortly after their 18th birthday, preventing any gap in your legal authority.

How Much Does a Limited Conservatorship Cost?

While court fees are standard across the state, attorney fees vary depending on the complexity of the case.

Expense TypeEstimated Cost (USD)
Superior Court Filing FeeGenerally $435 to file the initial petition.
Court Investigator FeeUsually $800 to $1,200 (can often be waived if the proposed conservatee is low-income).
Court-Appointed Attorney FeeThe court requires the child to have their own lawyer; fees range from $500 - $1,500 (often waived for Medi-Cal recipients).
Private Attorney FeesTypically $3,500 to $6,500+ for a standard, uncontested limited conservatorship.

Frequently Asked Questions (FAQ)

Does my child lose their right to vote?

Not necessarily. In California, a limited conservatee retains the right to vote unless the judge specifically finds that they are incapable of completing an affidavit of voter registration.

Do we have to go to court?

Yes. Both the proposed conservators (usually the parents) and the proposed conservatee (the adult child) must attend the probate court hearing, unless a doctor signs a specific form stating the child is medically unable to attend.

Can siblings be named as co-conservators?

Yes. Many parents choose to add an older sibling as a co-conservator so that if the parents pass away or become incapacitated, the sibling already has the legal authority to step in without starting a new court case.

Do I need a lawyer for this?

While you can file "pro per" (without a lawyer), probate courts are incredibly strict about filing deadlines, mandatory notices, and background checks. Hiring an attorney from our US Lawyer Directory ensures your petition is not delayed or dismissed.
