Probate Conservatorship California: Process, Timeline, and Real Costs

A probate conservatorship is what happens when your parent loses the ability to manage their own affairs and never signed a power of attorney. The court steps in, appoints someone to make decisions, and supervises the arrangement — permanently. It works, but the cost in time, money, and family stress is substantial.

Understanding the full process and real expenses helps you decide whether to pursue it or whether your parent still has enough capacity to execute a power of attorney instead.

What a Probate Conservatorship Covers

California's Probate Code Section 1801 creates two types of probate conservatorship, and you can petition for one or both:

Conservatorship of the person. Authority over your parent's personal care — where they live, what medical treatment they receive, daily care decisions. The conservator manages healthcare, housing, meals, and personal welfare.

Conservatorship of the estate. Authority over your parent's finances — bank accounts, investments, real property, income, bill payments, and contracts. This type comes with mandatory court reporting and bond requirements.

Most families need both if their parent has lost capacity entirely.

The Filing Process Step by Step

1. Prepare the petition package. You'll need the GC-310 petition, GC-312 confidential supplement, a capacity declaration from a physician (GC-335), and the notice and citation forms. An attorney typically prepares these, though self-represented petitioners can use the court's self-help resources.

2. File with the probate court. Filing fees vary by county but typically run $450–$500. The court sets a hearing date, usually 45–60 days out.

3. Serve the proposed conservatee. Someone not involved in the case must personally hand your parent the Citation (GC-320), informing them of the petition and their rights, at least 15 days before the hearing.

4. Mail notice to relatives. The Notice of Hearing (GC-020) must be mailed to all close relatives — spouse, children, parents, siblings — at least 15 days before the hearing.

5. Court investigator interview. The court appoints an investigator to visit your parent, assess their condition, interview family members, and file a report with recommendations. The investigator's report carries significant weight with the judge.

6. Attend the hearing. The judge reviews the petition, the investigator's report, and the medical evidence. Your parent has the right to attend and object. If the judge is satisfied that your parent lacks capacity and no less restrictive alternative exists, they issue Letters of Conservatorship (GC-350).

Real Cost Breakdown

Conservatorship costs add up fast, and many families are caught off guard by how much the ongoing expenses are:

Initial filing and establishment:

• Court filing fee: $450–$500
• Attorney fees for petition preparation: $3,000–$7,000
• Court investigator fee: $750–$1,500 (paid by the estate)
• Medical evaluation for capacity declaration: $300–$800
• Process server for citation: $75–$200

If you need an attorney at the hearing (contested cases): add $2,000–$5,000 or more.

Ongoing annual costs (conservatorship of the estate):

• Surety bond premium: 1–3% of the estate value per year. For a parent with $200,000 in assets, expect $2,000–$6,000 annually.
• Annual accounting preparation: $1,000–$3,000 if an attorney or accountant prepares it
• Court review hearing fees: vary by county
• Attorney fees for any motions or modifications: billed hourly at $300–$600

Total first-year cost for a typical case: $5,000–$15,000, depending on whether it's contested, how complex the estate is, and whether you use an attorney for the entire process.

The Bond Requirement

If you're appointed conservator of the estate, the court requires you to post a surety bond before you receive Letters of Conservatorship. The bond protects the conservatee's assets — if you mismanage funds, the bonding company pays the loss and then comes after you.

The bond amount equals the value of personal property in the estate (cash, investments, vehicles) plus the estimated annual income. Real property is typically excluded from the bond calculation unless the court orders otherwise.

You pay an annual premium to the bonding company — not the full bond amount. Premium rates depend on your credit score, the bond amount, and the bonding company's underwriting standards.

Some courts will waive the bond if the estate has minimal assets or if the conservator agrees to block accounts (accounts that require court authorization for any withdrawal).

Why the Court Investigator Matters

The court investigator's report often determines the outcome. The investigator is an independent officer of the court who:

• Visits your parent and assesses their current condition
• Determines whether your parent understands the conservatorship proceeding
• Evaluates whether less restrictive alternatives were considered
• Interviews the proposed conservator about their plans and qualifications
• Makes a recommendation to the judge

If the investigator recommends against conservatorship, or recommends a different conservator than who petitioned, you'll face an uphill battle at the hearing.

The Alternative: Power of Attorney

A durable power of attorney costs nothing if you use California's statutory form, takes about an hour to execute, and gives you the same financial and healthcare authority — without court involvement, bond premiums, annual accountings, or investigator reviews.

The catch: your parent must still have legal capacity to sign. Under California's sliding-scale capacity standard from Andersen v. Hunt, a parent with early to moderate dementia may still have sufficient capacity to execute a POA during a lucid period.

The California Power of Attorney & Guardianship Kit covers both pathways — the POA route for families with a closing window and the full conservatorship process for those who've already missed it.
