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 for as long as it remains in place. 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, GC-314 confidential screening form, a physician-signed capacity declaration (GC-355), 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. The base filing fee is $435, with local investigator or e-filing fees possible. The ordinary appointment process is estimated at 3–6 months.

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, the court may issue the Order Appointing Conservator (GC-340), followed by Letters of Conservatorship (GC-350) after appointment requirements are met.

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: $435 base fee, plus any local investigator or e-filing fees
• Attorney fees for petition preparation and representation: $5,000–$15,000+
• Court investigator fee: $500–$1,000, with local variation
• Medical evaluation for capacity declaration: varies by physician
• Process server for citation: varies by provider and county

If the case is contested: total attorney fees can exceed $10,000.

Ongoing annual costs (conservatorship of the estate):

• Surety bond premium: varies with estate size and the bonding company's underwriting; there is no universal annual range.
• 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: varies with county, case complexity, bond, and professional fees; attorney fees alone are reported at $5,000–$15,000+.

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 court sets the bond amount based on estate details, including personal property and estimated income; real property may be included depending on the conservator's authority.

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.

The court may waive or reduce the bond for good cause, and blocked accounts can reduce the required amount; local rules vary.

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 can be prepared using California's free statutory form, takes about an hour to execute, and gives you financial authority without court involvement; an AHCD handles healthcare decisions.

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.
