California Representative Payee vs Conservator

Two Separate Systems, Zero Overlap

One of the most common misunderstandings in California's turning-18 transition is assuming that a state probate conservatorship gives you authority over your child's Social Security benefits. It does not.

The Social Security Administration is a federal agency. It operates its own representative payee system under federal regulations, entirely separate from California's probate courts. The SSA will refuse to recognize a California Power of Attorney, a limited conservatorship order, or a Supported Decision-Making Agreement when it comes to managing SSI payments. It does not matter how many powers the probate judge granted or how comprehensive your court order is — the SSA will not honor it.

To manage your child's SSI benefits, you must apply directly to the SSA to be designated as a representative payee through the SSA's own administrative process.

What a Representative Payee Does

A representative payee receives SSI (or Social Security) payments on behalf of a beneficiary who the SSA has determined cannot manage their own funds. The payee must use the money exclusively for the beneficiary's current needs — food, housing, clothing, medical care, personal expenses — and keep records of how it was spent.

The SSA reviews the arrangement periodically and can change the payee designation if there is evidence of misuse or if the beneficiary demonstrates they can manage their own finances.

Key facts:

• Cost: Free. No filing fees, no attorney needed.
• Court involvement: None. This is an SSA administrative designation.
• Scope: Strictly limited to managing the beneficiary's federal benefit payments. A representative payee has no authority over bank accounts that hold non-benefit funds, no power to make medical decisions, and no say in housing or education.

The Age 18 Redetermination

When your child turns 18, two things happen with SSI:

Parental deeming ends. Before 18, the SSA "deems" (counts) a portion of the parents' income and resources when determining a child's SSI eligibility. At 18, deeming stops. Many young adults who were ineligible as minors because of their parents' income become eligible as adults based solely on their own (typically minimal) income and resources.

Adult eligibility redetermination. The SSA reevaluates your child's disability under adult disability criteria, which differ from children's criteria. The medical review looks at whether the individual can engage in "substantial gainful activity" rather than whether they have "marked and severe functional limitations." Most individuals with significant developmental disabilities continue to qualify, but the review process generates paperwork and anxiety.

If your child is currently receiving SSI and you are the representative payee, the payee designation typically continues past the 18th birthday. But if your child is applying for SSI for the first time at 18 (common when parental deeming ends), you will need to apply for representative payee status as part of the initial claim.

When You Need a Conservatorship Instead (or in Addition)

A representative payee handles SSI. It does not handle anything else. If your child receives an inheritance, a personal injury settlement, or earns income beyond SSI, the representative payee designation gives you no authority over those funds. For non-benefit assets, you need a Durable Power of Attorney (if your child can sign one) or a Conservatorship of the Estate (if they cannot).

Similarly, IHSS (In-Home Supportive Services) benefits are administered by the county, not the SSA. A parent can serve as their child's IHSS provider — being paid for caregiving hours — without being either a representative payee or a conservator. These are independent roles.

Medi-Cal eligibility at 18 follows its own rules. A conservatorship is not required for Medi-Cal enrollment or management, but you may need medical decision-making authority (via an Advance Health Care Directive or conservatorship of the person) to work with Medi-Cal providers.

The Practical Package

For most families navigating the turning-18 transition, the benefit management picture looks like this:

• SSI payments: Representative payee (apply through SSA)
• IHSS services: Separate application through your county social services agency
• Medi-Cal: Check eligibility and enrollment with Medi-Cal or your county
• Non-benefit finances: Durable Power of Attorney or conservatorship of the estate
• Medical decisions: Advance Health Care Directive or conservatorship of the person

None of these instruments substitutes for another. The representative payee manages SSI. The AHCD manages medical decisions. The DPA manages finances. Each operates in its own lane.

The California Adult Guardianship & Alternatives Guide maps each of these instruments to the specific domains they cover, with preparation checklists for the SSA representative payee application alongside the other turning-18 instruments.
