CA Special Needs Trust Guide 2026

Short answer: A special needs trust lets a California family leave money or property to a person with a disability without that gift itself disqualifying the person from needs-based government benefits such as SSI and Medi-Cal. The trust holds the assets, a trustee manages them under California trust law, and the beneficiary uses the trust only to supplement, not replace, what those programs already provide. The tradeoff is real: the money stops being the beneficiary’s directly, and the trustee takes on legal duties that carry consequences if ignored.

What does a special needs trust actually do?

SSI and Medi-Cal are needs-based programs. They look at what a person owns and controls, not just what they earn. If a family member leaves an inheritance directly to a person receiving those benefits, or gives them a large cash gift, the assets can count against the program’s resource rules and put ongoing eligibility at risk. A special needs trust removes that problem by putting the assets in a separate legal entity. The beneficiary does not own the trust property outright and cannot demand a lump sum from it, so the resource does not count the same way a direct inheritance would.

The trust still has to be used correctly. Distributions are meant to pay for things the government programs do not already cover: specialized therapy, adaptive equipment, education, transportation, recreation, and personal care beyond what Medi-Cal provides. A trustee who pays for something the program already covers, or who hands cash directly to the beneficiary, can create the same eligibility problem the trust was built to avoid.

What is the difference between a first-party and a third-party trust?

California families use two basic structures. A first-party (or self-settled) special needs trust is funded with the beneficiary’s own money, most commonly a personal injury settlement or an inheritance the beneficiary already received outright before anyone stepped in to redirect it. Because the money belonged to the beneficiary, this type of trust comes with a repayment obligation to the state’s Medi-Cal program out of whatever remains when the beneficiary dies.

A third-party special needs trust is funded by someone other than the beneficiary, typically a parent or grandparent planning ahead. Because the beneficiary never owned the assets, there is no repayment obligation to the state. This is the structure most families use when they are planning proactively rather than reacting to a settlement or an inheritance that already landed in the wrong hands. Getting the funding source and the trust structure to match matters; using the wrong type of trust for the source of the money can undo the protection the trust was supposed to provide.

Who should serve as trustee, and what does California law require of them?

The trustee decision is where a lot of special needs trusts go wrong. A trustee needs to understand both trust administration and the benefit rules, and needs enough emotional distance to say no to a distribution request that would jeopardize eligibility, even when the request comes from a parent or sibling. Family members who love the beneficiary are not always the right choice for that reason. Many families name a professional fiduciary or a corporate trustee, sometimes paired with a family member who understands the beneficiary’s daily needs but does not control the checkbook.

Whoever serves takes on the same legal duties any California trustee owes. A trustee must administer the trust according to its terms and the law, and act within a reasonable time, under Probate Code § 16000. A trustee cannot use trust property for personal benefit, under Probate Code § 16004. Beneficiaries, or in the case of a beneficiary who lacks capacity, the people looking out for them, are entitled to accountings from the trustee under Probate Code §§ 16060 through 16063. If a trustee will not account, will not follow the trust terms, or is mismanaging the assets, an interested party can petition the court to compel an accounting, get instructions, or in serious cases remove the trustee, under Probate Code § 17200. Special needs trusts do not get an exception from any of this. If anything, the stakes are higher, because a trustee’s mistake can cost the beneficiary both trust assets and government benefits at the same time.

What mistakes put a beneficiary’s benefits at risk?

The most common error is simple: someone names the person with a disability directly as a beneficiary on a life insurance policy, retirement account, or will, instead of naming the trust. A trust that exists on paper but never gets funded protects nothing. The second most common error is a trustee distribution that looks generous but backfires, cash handed directly to the beneficiary, rent or a mortgage paid in the beneficiary’s name in a way that counts as in-kind support, or a purchase that duplicates something the government program already provides. Each of those can reduce or eliminate the very benefits the trust was set up to protect.

A trust also is not a one-time project. A beneficiary’s medical needs change, benefit program rules change, and family circumstances change. A trust drafted years ago without a review can drift out of step with current rules, or with a trustee who is no longer the right fit. Some families also use a companion savings account designed for people with disabilities alongside the trust, which lets the beneficiary hold limited funds directly for everyday expenses without affecting eligibility, while the trust holds the larger assets and pays for bigger needs.

What to do next

If a family member with a disability is receiving or is likely to receive an inheritance, a settlement, or a significant gift, get the trust in place and funded before the money changes hands, not after. Talk with an estate planning attorney about which trust structure fits the source of the funds, and build in a trustee arrangement and a plan for ongoing trust administration that will hold up over the beneficiary’s lifetime, not just at signing.
