Conservatorship vs Guardianship California: What's the Difference?

If you've been searching for "guardianship for elderly parent in California," you won't find what you're looking for — because California doesn't use that term for adults. Every result you see about "adult guardianship" is either from another state or using the wrong legal term.

In California, guardianship applies exclusively to minors. The equivalent process for an incapacitated adult is called a conservatorship. The distinction isn't just terminology — it affects which court forms you file, which legal standards apply, and which Probate Code sections govern your case.

The Legal Distinction

Guardianship (Probate Code Sections 1500–1612) covers minors under 18. A guardian of the person has authority over the child's daily care, education, and medical treatment. A guardian of the estate manages the child's property and finances.

Conservatorship (Probate Code Sections 1800–1898, 2100–2893) covers adults who cannot provide for their own personal needs or manage their own finances. A conservator of the person handles residence, healthcare, and daily living decisions. A conservator of the estate manages income, assets, bills, and property.

Types of Conservatorship in California

California has three main categories, each serving different situations:

General probate conservatorship. The most common type for aging parents. You petition the court to prove — by clear and convincing evidence — that your parent cannot provide for food, clothing, shelter, or health needs, or cannot manage their own finances. This is filed under Probate Code Section 1801.

Limited conservatorship. Designed for adults with developmental disabilities. The court grants only the specific powers needed, preserving as many rights as possible. This is not typically used for age-related decline.

LPS conservatorship (Lanterman-Petris-Short Act). Reserved for individuals with severe mental illness who are gravely disabled. This is initiated by a professional (usually a psychiatrist), not by family members, and involves mandatory treatment.

For most families dealing with an aging parent's cognitive decline, the general probate conservatorship is the relevant process.

What the Process Requires

Filing for conservatorship involves multiple steps over 60 to 90 days:

1. Petition filing. You submit Form GC-310 (Petition for Appointment of Probate Conservator) to the superior court in the county where your parent resides. Filing fees run $450 to $500.

2. Court investigator interview. The court assigns an investigator to interview your parent, assess their condition, and interview you about your qualifications and plan.

3. Service and notice. A citation (Form GC-320) must be personally served on your parent by a third party. Notice of the hearing (Form GC-020) must be mailed to all close relatives — spouse, adult children, siblings, and parents.

4. Hearing. The judge evaluates the evidence, considers whether conservatorship is the least restrictive alternative available (Probate Code Section 1800.3), and decides whether to grant the appointment.

5. Letters of conservatorship. If approved, the court issues Letters (Form GC-350), which you present to banks, hospitals, and agencies as proof of your authority.

Why Avoiding Conservatorship Is Usually Better

Conservatorship works, but it's the most invasive option available. It strips your parent of civil rights, subjects the family to ongoing court supervision, and costs thousands of dollars between attorney fees, filing fees, investigator fees, and surety bonds.

If your parent still has legal capacity — even limited capacity — executing a Durable Power of Attorney and an Advance Health Care Directive while they can still sign gives you equivalent authority without court involvement, at a fraction of the cost and time.

The California Power of Attorney & Guardianship Kit covers both paths: the voluntary POA route for parents who can still sign, and the full conservatorship process — forms, timelines, cost worksheets, and investigator preparation — for families who've passed that window.

What Other States Call It

If you're researching from out of state or reading material from other jurisdictions, be aware that most states use "guardianship" for adults. Only California and a handful of other states use "conservatorship" as the primary term. If you see advice about "adult guardianship" from a national legal site, the general process is similar, but the specific forms, court procedures, and Probate Code sections are California-specific.

When searching for California information, always use "conservatorship" — it will lead you to the right forms, the right court, and the right legal standards.
