Third Party vs First Party Special Needs Trust in California: What Is the Difference?

Why the Distinction Matters So Much

Both types of special needs trusts allow a person with a disability to have assets held for their benefit without those assets counting toward the resource limits that determine eligibility for Supplemental Security Income and Medi-Cal. That is the shared goal.

The distinction comes down to one question: whose money is going into the trust?

If the money belongs to the person with the disability, a first party special needs trust applies. If the money belongs to someone else, typically a parent, grandparent, or other family member, a third party special needs trust applies.

That single distinction changes the rules around how the trust is established, who can create it, and most significantly what happens to the remaining assets when the beneficiary dies.

Third Party Special Needs Trust: Planning From Love

A third party special needs trust is funded with assets that belong to someone other than the person with the disability. This is the trust parents create when they are doing estate planning and want to make sure their child with a disability is provided for after they are gone.

Think of it this way. A mother and father in San Diego have two children. One child has no disability. The other has autism and relies on Medi-Cal for healthcare and SSI for monthly income support. The parents want to leave equal love and equal care to both children, but they know that leaving money directly to their child with a disability would immediately disqualify him from the benefits he depends on.

The solution is a third party special needs trust. The parents create the trust as part of their overall estate plan. When they die, their child's share of the estate flows into the trust rather than to him directly. The trustee uses those funds to pay for things that improve his quality of life, technology, recreation, travel, therapy not covered by Medi-Cal, without those funds ever being counted as his personal assets. His SSI and Medi-Cal remain intact.

When he eventually dies, whatever remains in the trust passes to whoever the parents named as remainder beneficiaries, typically other family members or a charity of their choice. California has no claim on those funds. The state does not get reimbursed for Medi-Cal benefits paid during his lifetime. The money stays in the family.

That last point is not a small detail. It is one of the most significant advantages of a third party special needs trust and one of the most important reasons families doing proactive estate planning should never accidentally use a first party trust structure when a third party trust is what the situation calls for.

First Party Special Needs Trust: When the Money Already Belongs to the Beneficiary

A first party special needs trust, also called a self-settled special needs trust or a d4A trust after the federal statute that authorizes it, is funded with assets that already belong to the person with the disability.

This situation arises more often than families expect. Common scenarios in California include:

• A young woman with cerebral palsy receives a personal injury settlement after a car accident. The settlement is substantial. If she simply holds that money in her own name, she immediately loses SSI and Medi-Cal eligibility. She needs a first party special needs trust to hold the settlement funds while preserving her benefits.
• A man with an intellectual disability inherits money directly from a grandparent who did not have a special needs trust in their estate plan. The inheritance is now in his name. A first party special needs trust can be used to hold those funds and restore his benefit eligibility, but the window to act is limited and the rules are strict.
• An adult with a disability receives a divorce settlement or retroactive Social Security back pay that exceeds the asset limits for SSI. A first party trust can address the eligibility problem.

In each of these situations the money already belongs to the person with the disability. There is no other option. A third party trust cannot be used because the assets are not coming from a third party. The first party trust is the only available vehicle.

The Rules That Come With a First Party Trust

First party special needs trusts come with requirements that third party trusts do not have. Families navigating this situation need to understand all of them before proceeding.

The beneficiary must be under age 65 when the trust is established. This age limit is set by federal law. An adult with a disability who is 65 or older cannot create a first party special needs trust. Other planning options, including a pooled special needs trust, may be available depending on the situation, but the standard first party trust is not available after 65.

The trust must be irrevocable. Once established and funded, a first party special needs trust cannot simply be undone. The assets are committed to the trust structure.

A parent, grandparent, legal guardian, or court must establish the trust. The beneficiary cannot create it for themselves. This requirement exists because federal law requires oversight in the creation of these trusts to protect the beneficiary's interests.

California must be named as a primary remainder beneficiary. This is the Medi-Cal payback provision. When the beneficiary dies, California is entitled to reimbursement from whatever remains in the trust for Medi-Cal benefits paid on the beneficiary's behalf during their lifetime. After the state is reimbursed, any remaining assets can pass to other named remainder beneficiaries.

This payback requirement is the defining difference from a third party trust and the reason the choice between the two matters so much for families.

Side by Side: The Key Differences

The choice between a third party and first party special needs trust is not a preference. It is determined by the facts of your situation. Here is how the two structures compare across the factors that matter most.

Whose money funds the trust: Third party trusts are funded by parents, grandparents, or other family members. First party trusts are funded with the beneficiary's own assets.

Who can create the trust: A third party trust can be created by any family member doing estate planning. A first party trust must be created by a parent, grandparent, legal guardian, or court.

Age restriction: Third party trusts have no age restriction on the beneficiary. First party trusts require the beneficiary to be under 65 at establishment.

Medi-Cal payback on death: Third party trusts have no payback requirement. Remaining assets pass to named heirs. First party trusts require California to be reimbursed for Medi-Cal benefits paid before any assets pass to other heirs.

Best used for: Third party trusts are best for proactive estate planning by family members. First party trusts are best for managing assets that already belong to the beneficiary, such as a personal injury settlement or direct inheritance.

A Situation Where Getting This Wrong Has Real Consequences

Consider a grandfather in San Diego who wants to leave $200,000 to his granddaughter with Down syndrome when he dies. He has heard about special needs trusts and asks his financial advisor to handle it. Without proper legal guidance, the advisor names the granddaughter directly as the beneficiary of a life insurance policy and suggests she use a first party trust to hold the funds after she receives them.

The result: the granddaughter receives the $200,000 directly, immediately loses SSI and Medi-Cal eligibility, and must spend down the funds before her benefits can be reinstated. When she eventually establishes a first party trust with the remaining assets, those funds are subject to the Medi-Cal payback requirement on her death.

The alternative with proper planning: the grandfather's estate plan includes a third party special needs trust. The life insurance policy names the trust as beneficiary. The $200,000 flows into the trust at his death, her benefits remain intact, the funds are used to improve her quality of life over time, and when she eventually passes whatever remains in the trust goes to other family members with no Medi-Cal payback.

Same grandfather. Same granddaughter. Same $200,000. Completely different outcome based entirely on whether the right trust structure was used.

What Happens When You Need Both

Some families find themselves in a situation where both trust types are relevant simultaneously.

A mother creates a third party special needs trust in her estate plan for her adult son with a disability. Years later, her son is in a car accident and receives a personal injury settlement in his own name. The settlement cannot go into the existing third party trust because it belongs to him, not to a third party. A separate first party special needs trust must be established for the settlement funds.

The son now has two trusts operating in parallel. The third party trust, funded by his mother's estate plan, has no payback requirement. The first party trust, funded by his settlement, has the Medi-Cal payback requirement. Both protect his benefit eligibility. The trustee must administer them separately and track which funds come from which trust for purposes of what happens when he eventually dies.

This is not an unusual situation. It is exactly the kind of complexity that makes working with an attorney experienced in special needs planning so important. The administrative details matter enormously and the consequences of getting them wrong fall on the beneficiary and the family.

How These Trusts Fit Into a Complete Estate Plan

For families doing proactive planning, the third party special needs trust does not stand alone. It is one component of a complete estate plan built around the needs of a family member with a disability.

A revocable living trust is typically the primary estate planning vehicle. Within that trust, the special needs provisions for the beneficiary with a disability are structured as a sub-trust or separate third party special needs trust. When the parent or grandparent dies, the assets designated for the beneficiary flow into the special needs trust automatically, with no court involvement, no probate delay, and no risk of the assets landing in the beneficiary's hands directly.

Beneficiary designations on life insurance policies and retirement accounts must be reviewed and updated to name the special needs trust, not the individual with a disability, as the beneficiary. This is one of the most commonly missed steps in special needs estate planning and one of the most consequential if overlooked. A life insurance policy that names your child with a disability directly bypasses the trust entirely and delivers the funds straight to them, potentially eliminating their benefits in an instant.
