California Conservatorship vs Power of Attorney: Which Legal Tool Do You Need?
Two Different Legal Frameworks
A conservatorship and a power of attorney both let one person make decisions on behalf of another. But they operate under fundamentally different legal frameworks, and choosing the wrong one can cost your family thousands of dollars in unnecessary court fees — or leave your adult child without adequate protection.
Power of Attorney: Voluntary and Private
A Durable Power of Attorney (DPOA) is a document your adult child signs voluntarily, delegating financial and legal decision-making to a chosen agent. An Advance Health Care Directive (AHCD) does the same for medical decisions. Both operate under the Probate Code (§ 4000 and § 4600 respectively) and require no court involvement.
Key characteristics:
- The person granting the POA must have capacity to sign it
- It can be revoked at any time by the person who signed it
- No court filing, no hearing, no investigator
- Costs $0 to $500 depending on whether you use an attorney
- The agent has no court oversight — accountability comes from the terms of the document and general fiduciary duty law
Conservatorship: Court-Ordered and Supervised
A conservatorship is a court order that transfers specific decision-making authority from one person to a court-appointed conservator. It requires a petition, a hearing, investigation by both a court investigator and the Regional Center, and appointment of legal counsel for the proposed conservatee.
Key characteristics:
- Does not require the conservatee's consent
- Cannot be unilaterally revoked — termination requires a court petition
- The $435 filing fee plus $3,000 to $10,000 in attorney fees for an uncontested case
- Ongoing court oversight through annual accounting followed by at least biennial accountings and investigator reviews
- The conservator is accountable to the court, with sanctions for mismanagement

Special Needs Trust: Asset Protection
A Special Needs Trust (SNT) is a distinct tool that protects assets while preserving eligibility for SSI, Medi-Cal, and other means-tested benefits. It is not a substitute for either a POA or a conservatorship — it works alongside them.
A third-party SNT (funded by the family) has no payback requirement and no court supervision unless it is a court-supervised trust. A first-party SNT (funded with the disabled person's own assets, such as a personal injury settlement) must include a Medicaid payback provision and may require court approval.
Neither a conservatorship nor a POA gives automatic access to trust assets. If assets are held in a SNT, the trustee — who may be a different person entirely — controls distributions.
The Decision Matrix
| Factor | Power of Attorney | Conservatorship | Special Needs Trust |
|---|---|---|---|
| Capacity to sign required | Yes | No | Depends on trust type |
| Court involvement | None | Full — petition, hearing, ongoing | Only if court-supervised |
| Cost to establish | $0–$500 | $3,000–$10,000+ | $2,000–$5,000 (attorney-drafted) |
| Ongoing costs | None | $1,500–$5,000 every 2 years | Trustee fees if professional |
| Can be revoked by the person | Yes, at any time | No — requires court petition | Depends on trust terms |
| Protects benefits | No (but does not affect them) | No (but does not affect them) | Yes — primary purpose |
| Institutional recognition | Strong but sometimes resisted | Strongest — court order | N/A — asset-level tool |
When POA Is the Right Choice
A POA is the right tool when your adult child has the capacity to sign, you trust that they will not revoke it under outside pressure, and you need authority over financial and healthcare decisions without the cost and intrusion of court involvement. For most families navigating the transition at 18, a combination of DPOA, AHCD, and Supported Decision-Making Agreement covers every practical need.
When Conservatorship Is Necessary
Conservatorship is the right tool when your adult child cannot understand the concept of delegating authority (and therefore cannot sign a POA), when there is a genuine risk that private documents will be revoked under manipulation, when institutions consistently refuse to honor private planning documents, or when the court's oversight function is itself a benefit — for example, when family members disagree about care decisions.
Layering the Tools
These are not mutually exclusive. Some families execute a POA and AHCD to cover routine decisions, establish a SNT to protect assets, and file a limited conservatorship requesting only the one or two powers where court authority is genuinely needed. This layered approach preserves maximum autonomy while providing court-backed protection only where it is truly necessary.
