A self-settled trust (SST), sometimes called a self-settled special needs trust or Medicaid trust, is fundamentally distinguished by who creates it and whose assets fund it. The core difference between first-party and third-party versions lies in the settlor—the person creating the trust. A first-party SNT is created by or for an individual using their own assets, while a third-party SNT is created by someone else, usually a parent or family member, using their own assets for the benefit of another person. For someone approaching retirement who has become disabled or is planning for long-term care, a first-party SNT allows you to place your own money into a trust structure that can preserve your eligibility for government benefits like Medicaid and Supplemental Security Income (SSI), whereas a third-party SNT serves the same protective function but is created and funded by parents or guardians on behalf of a disabled family member. Understanding this distinction matters profoundly because the rules governing each type differ in significant ways, particularly around payback provisions, funding amounts, and what happens to remaining trust assets when the beneficiary passes away.
Consider a 45-year-old who receives a $200,000 inheritance and is receiving SSI and Medicaid due to a disability. If this person creates a first-party SNT and places the inheritance into it, the trust structure protects their government benefits. However, at their death, Medicaid has a legal claim to recover what it spent on the beneficiary from any remaining trust assets—a requirement that does not apply to third-party SNTs. This “payback” provision is one of the most critical differences retirees and families need to understand when planning for disability or long-term care. The stakes are high enough that mistakes in choosing which type of trust to use, or in how the trust is structured, can result in the loss of critical benefits that support living expenses and medical care. This is why retirement and disability planning often intersect: many people who are approaching retirement age either need to plan for their own potential disability or are creating plans for adult children who are disabled and will need ongoing support after the parents’ retirement years are over.

How Do First-Party and Third-Party SNTs Differ in Their Legal Origins and Funding?
The legal origin of an SNT determines which rules apply to it and how it must be structured to work properly. A first-party SNT is established by the beneficiary themselves—or, in the case of a minor or legally incapacitated person, by their legal representative or guardian using funds that belong to that individual. Common scenarios include: a person receiving a personal injury settlement, an inheritance, or proceeds from a lawsuit who needs to protect those assets while maintaining government benefits; or a guardian who has received a legal settlement on behalf of a minor with disabilities and must place the money into a first-party SNT by court order. A third-party SNT, by contrast, is created and funded by parents, grandparents, or other family members using their own assets, specifically for the benefit of a loved one who is disabled.
The third-party version is typically created during the parents’ lifetime or through their will or living trust as part of their estate plan. This distinction in origin creates immediate practical differences. First-party SNTs require strict compliance with Medicaid law because they are using the beneficiary’s own assets to fund the trust; any misstep in the trust language or administration can result in the trust assets being considered a countable resource, disqualifying the beneficiary from Medicaid. Third-party SNTs, while also subject to Medicaid rules to protect the beneficiary’s benefits, have greater flexibility in their structure because they are funded with someone else’s money and are not subject to the same state-by-state variations in how they must be drafted. A parent in California setting up a third-party SNT for an adult child with cerebral palsy, for example, has fairly standard national guidelines to follow; a person in California who receives a $150,000 settlement and wants to create a first-party SNT must navigate California-specific Medicaid rules about how the trust must be titled, who can serve as trustee, and how it can be administered.
The Medicaid Payback Provision and Why It Transforms Estate Planning for First-Party Trusts
The most consequential difference between first-party and third-party SNTs is the Medicaid payback (or recovery) requirement. When someone creates a first-party SNT and receives Medicaid benefits while using that trust, federal law requires that any remaining assets in the trust at the beneficiary’s death be used to reimburse the state Medicaid program for all the long-term care services it paid on behalf of that individual. This is not a penalty or unusual rule—it is a structural requirement of the federal Medicaid program for first-party trusts. If a 68-year-old retiree places $300,000 into a first-party SNT, receives 15 years of Medicaid-funded nursing home care costing $450,000, and passes away with $50,000 remaining in the trust, that remaining $50,000 goes to the state, not to the family. Third-party SNTs are not subject to this payback requirement. Any remaining assets in a third-party SNT pass to the beneficiary’s estate or to whoever the trust document designates as remainder beneficiaries, typically family members.
This is why many families choose the third-party structure when possible: it allows them to leave a legacy or ensure that their child has discretionary spending from the remaining trust balance after their death. The payback requirement creates a fundamental planning challenge for first-party SNTs. It means that the trust is not primarily a wealth transfer vehicle—it is a benefit preservation tool. Parents who have worked their entire lives to accumulate savings often face a difficult choice: if they want to leave money to a disabled adult child, should they put it in a first-party SNT for the child (knowing the state will recover those assets when the child dies), or should they use a third-party trust structure instead? The answer depends on the specific family situation, the child’s life expectancy, and the amount of assets involved. A parent with $500,000 to pass to an adult child with severe disabilities might decide that funding a third-party SNT during their lifetime makes more sense than leaving the money in a way that triggers Medicaid recovery. Conversely, someone receiving a personal injury settlement may have no choice but to use a first-party SNT if they want to protect their government benefits while using that settlement to enhance their quality of life. The payback provision also means that retirees who create a first-party SNT should plan carefully with an elder law attorney about which assets to fund into the trust versus which to keep separate, because everything in the trust is subject to Medicaid recovery.
Who Can Serve as Trustee and How That Affects Administration and Control
The trustee of an SNT—the person or institution responsible for managing the trust and making distributions—plays a crucial role in how well the trust works for the beneficiary. For first-party SNTs, the law places restrictions on who can serve as trustee, and these restrictions vary by state. Many states require that the trustee be someone other than the beneficiary; in some cases, a professional trustee or corporate trustee is required. This is because a first-party SNT must maintain a careful distance between the beneficiary and the control of trust assets in order to preserve government benefits. If a beneficiary has too much control over the trust—for example, if they can demand distributions whenever they want, or if they effectively control how the trustee spends money—the trust may not be treated as a separate resource by Medicaid, and the beneficiary could lose benefits. For someone creating their own first-party SNT, this means they must be willing to give up some day-to-day control over their money, placing it instead in the hands of a trustee who has discretion about what distributions are appropriate. Third-party SNTs often have greater flexibility regarding who can serve as trustee, particularly in the early years.
A parent might serve as trustee of a third-party trust while they are living, maintaining control over how money is spent for their disabled child. Upon the parent’s death, the trust documents typically specify a successor trustee—perhaps another adult sibling of the beneficiary, or a professional trustee if family members are not available or not suitable. However, the trustee of a third-party SNT is still bound by fiduciary duties and by the trust terms, and they cannot simply give the beneficiary access to all the trust assets without jeopardizing the beneficiary’s government benefits. A common real-world example: A mother creates a third-party SNT for her adult son who has autism and receives SSI. While she is living, she serves as trustee and carefully manages distributions—paying for therapies, equipment, rent supplements, and recreational activities that Medicaid does not cover. When the mother dies and her daughter takes over as trustee, the daughter must continue to honor those same rules about discretionary distributions, even though she now has legal control of a substantial sum of money. The rules don’t change just because a new trustee took over; what changes is who has the responsibility and authority to enforce those rules appropriately.
Practical Funding Strategies and Tax Considerations for Retirees
For retirees considering how to structure assets for long-term care or for a disabled family member, the funding strategy differs significantly between first-party and third-party SNTs. A retiree with pension income, Social Security, and modest savings might decide that protecting those savings through a first-party SNT makes sense if they anticipate that long-term care could deplete their assets and require Medicaid. In this scenario, the person might fund the first-party trust with savings and certain accounts—perhaps liquid investments or non-retirement assets—while keeping their primary residence and certain exempt assets outside the trust. The advantage is that the trust assets are protected and not counted as a resource for Medicaid purposes. The disadvantage is the payback provision: when the person passes away, any remaining assets go to Medicaid recovery, not to their heirs. Parents funding a third-party trust typically do so from their own assets and have more flexibility about what to fund. A parent might use life insurance proceeds to fund a third-party trust, set aside a portion of an inheritance, or designate trust funding in their will. The tax treatment differs as well: first-party SNTs created with the beneficiary’s own assets may be taxable trusts for income tax purposes, meaning the trust itself pays income taxes on trust earnings. Third-party SNTs are typically intentionally defective grantor trusts or other structures that may have different tax implications.
A concrete example: A 72-year-old retired accountant has $180,000 in a savings account and $450,000 in investment accounts, plus Social Security income of $2,800 per month. She is in good health but fears that a stroke or dementia could lead to years in a nursing facility. She works with an elder law attorney to fund a first-party SNT with $150,000 from savings, keeping $30,000 in emergency cash outside the trust and maintaining her investments. If she eventually needs Medicaid for long-term care, the $150,000 in the SNT will be protected for supplemental expenses and will not be counted as a resource. However, she understands that if she lives 20 years and passes away with $80,000 remaining in the trust, that $80,000 will go to pay back Medicaid, not to her two adult children. She accepts this trade-off because her priority is protecting her dignity and having resources for comfort care during her lifetime. Compare this to a 68-year-old parent of a 42-year-old adult child with Down syndrome: this parent creates a third-party SNT with $200,000 from their estate, naming their healthy sister as trustee and remainder beneficiary. When the parent dies, the trust is funded and the beneficiary begins receiving supplemental care from the trust. The remaining assets after the beneficiary’s death will go to the sister’s family, not to Medicaid recovery—a legacy that matters to the parent’s overall family plan.
Common Pitfalls and Compliance Issues That Jeopardize Benefits
Even with good intentions, mistakes in how a first-party SNT is created or administered can result in loss of government benefits and create financial hardship. One common pitfall is improper titling of the trust. A first-party SNT must be set up in a way that clearly identifies the trust as the owner of assets, not the individual beneficiary. If a person creates a first-party SNT but then titles bank accounts or investment accounts in their own name “as trustee” or fails to formally fund the trust with actual assets, Medicaid may not recognize the trust as a valid protective structure and may count all those assets as available resources. Another frequent problem occurs when a beneficiary has too much access or control. For example, if a first-party SNT document gives the beneficiary the right to demand all distributions whenever they wish, or if the trustee regularly just hands over money at the beneficiary’s request without discretion, the trust is not functioning as intended and may not protect benefits. A third-party trust is somewhat more forgiving because the beneficiary was not the one who created it and did not fund it, so the legal standard for how much control they can have is less strict.
However, a third-party SNT can still fail if it is administered recklessly—for instance, if the trustee routinely gives the beneficiary unlimited cash or pays for things that the beneficiary could otherwise pay for using their SSI benefits, the state may decide that the trust is being used improperly and reduce SSI benefits anyway. A critical warning: state Medicaid programs vary in how strictly they interpret SNT rules, and some states are more aggressive about challenging trust structures or imposing penalties. A first-party SNT created in one state may be recognized as valid, but if the beneficiary moves to a different state, that state’s Medicaid program may not recognize the same trust structure as adequate, leading to disputes about benefit eligibility. This is why ongoing legal compliance and professional trustee management are not luxuries—they are necessities for protecting benefits over time. A beneficiary who receives an inheritance, creates a first-party SNT themselves without proper legal guidance, and then makes a distribution error could find themselves disqualified from Medicaid, facing bills of thousands of dollars per month for long-term care. Similarly, a successor trustee of a third-party SNT who does not understand the rules might make innocent errors—like paying the beneficiary’s rent directly to the landlord in a way that is counted as an “in-kind” benefit that reduces SSI—creating unintended benefit losses. Regular consultation with an elder law attorney or special needs planner is often essential to keep the trust compliant over many years.
Integration with Estate Planning and Retirement Asset Distribution
For retirees approaching the end of their planning years, integrating an SNT strategy into the overall estate plan requires careful coordination. If a retiree has both a spouse and a disabled adult child, the questions become complex: Should the child’s inheritance go into a first-party or third-party SNT? Who should be the trustee? How much should be in the SNT versus other estate gifts? A common estate plan approach is to keep most assets passing to the healthy adult children outright, while designating a portion—whether through a will-funded trust or life insurance—to a third-party SNT for a disabled family member. This allows the parents to ensure that the disabled child is cared for without worrying about managing the money themselves, while preserving the normal inheritance flow to the other children. Another approach is to name the SNT as a beneficiary of retirement accounts or life insurance policies directly, allowing those assets to flow into the trust without going through probate. For someone planning their own estate when they themselves have a disability or chronic condition, the dynamics are different.
A retiree who receives Social Security, has modest savings, and is concerned about leaving a legacy while protecting their own benefits might decide to create a will that funds a third-party SNT for a family member, or to fund a first-party SNT during their lifetime with specific assets they’ve designated for that purpose. The key is that the estate plan must align with the SNT strategy; failing to do so can result in assets going directly to the beneficiary outside the trust structure, creating an unintended windfall that destabilizes their benefits. A specific example: A 65-year-old widow with SSI and Medicaid has $50,000 in a savings account and a modest home. She wants to leave money to her adult son with cerebral palsy but fears that a direct inheritance will cost him his benefits. She creates a will that leaves the $50,000 to a testamentary trust (a trust created through her will), which is drafted as a third-party SNT for her son. Upon her death, the $50,000 is not distributed directly to the son; instead, it is held in trust and can be used to provide supplemental care, vacations, therapy, and other benefits that enhance his life without triggering benefit loss.
The Evolution of SNT Planning and Future Considerations
SNT planning has evolved significantly over the past 20 years as case law has clarified what makes a valid first-party SNT and as practitioners have developed best practices for administering these trusts over the long term. One major evolution has been the recognition that SNTs can be used strategically in elder law and retirement planning, not just for disabled children. The Medicaid expansion and subsequent legal developments have opened doors for retirees to protect assets through first-party SNTs in ways that were not widely understood a decade ago. Looking forward, several trends are shaping how SNTs will function in retirement and disability planning. First, there is increasing use of pooled trusts, where a nonprofit organization serves as trustee for multiple beneficiaries’ first-party SNTs, allowing individuals with modest resources to access professional trustee services without the high costs of hiring a private corporate trustee.
Second, there is growing attention to the intersection of SNT planning with special needs planning when a retiree has both their own long-term care needs and responsibility for a disabled adult child. Third, some states are experimenting with modifications to Medicaid recovery rules for first-party SNTs, recognizing the tension between Medicaid cost-containment and the desire of families to leave legacies and protect their children’s quality of life. For retirees and families planning today, the key forward-looking insight is that SNT planning is increasingly recognized as a core component of comprehensive retirement and disability planning, not an isolated special needs tool. As more families face the reality of increased longevity and higher long-term care costs, the ability to structure assets in ways that protect government benefits while maintaining dignity and quality of life becomes more valuable. The choice between first-party and third-party approaches is not merely a technical legal question—it is a reflection of the family’s values, their wishes about legacy, and their realistic assessment of how long-term care costs and government benefits will intersect in their lives.
Conclusion
The fundamental difference between a first-party SNT and a third-party SNT is who creates it and whose assets fund it, but the implications of this difference touch nearly every aspect of how the trust functions, how it interacts with government benefits, and what happens to remaining assets after the beneficiary’s death. The Medicaid payback requirement for first-party SNTs—the requirement that remaining trust assets be used to reimburse the state for benefits provided—is the single most important distinction. Retirees considering a first-party SNT to protect their own assets must accept that those assets may ultimately go to Medicaid recovery rather than to their heirs.
Families funding a third-party SNT have greater certainty that they can leave a legacy, but they must still structure the trust carefully to protect the beneficiary’s benefits throughout their life. For anyone approaching retirement who either has a disability themselves or has responsibility for a disabled family member, working with an experienced elder law attorney or special needs planner is not optional—it is an essential step. The difference between a well-structured SNT and a poorly designed one can be measured in thousands of dollars per year in lost benefits, or alternatively, in the ability to provide years of enhanced care and dignity for someone who depends on both family resources and government support. Start by clarifying your specific situation: Are you protecting your own assets for your own long-term care? Are you planning for a child or grandchild who is disabled? Do you have assets to pass on, or are you primarily concerned with preserving government benefits? Once you understand your situation clearly, you can work with an attorney to determine whether a first-party SNT, a third-party SNT, or some combination of planning tools is the right approach for your family’s security and legacy.
Frequently Asked Questions
Can I change a first-party SNT into a third-party SNT later if my situation changes?
Generally, no. Once a first-party SNT is created and funded, changing its fundamental structure is difficult and may create tax or benefit complications. If you are considering creating a first-party SNT, spend time with an attorney upfront to make sure it is truly the right structure for your needs.
If I receive a settlement or inheritance, am I required to put it in a first-party SNT, or is it optional?
If you are receiving government benefits like SSI or Medicaid and you want to keep those benefits, you must protect a significant settlement or inheritance through a first-party SNT or similar structure. If you do not create an SNT, the assets will be counted against you and you will lose benefits. In some cases, a court may require you to create a first-party SNT as a condition of approving a settlement.
Who decides how money is spent from a third-party SNT if the beneficiary is an adult?
The trustee has discretion to decide what distributions are appropriate, but the trustee is bound by the trust document and by fiduciary law. The trustee cannot just give money directly to the beneficiary whenever they ask; instead, the trustee decides whether specific purchases or expenses are appropriate under the rules of the trust and the rules of government benefits like SSI and Medicaid.
If my parent creates a third-party SNT for me, does that affect my Social Security disability benefits (SSDI) the same way as affecting SSI?
No. SSI is means-tested, so the trust structure is critical to protecting SSI eligibility. SSDI (Social Security Disability Insurance) is not means-tested, so the SNT is less critical for protecting SSDI. However, a third-party SNT can still affect your ability to use the resources for other purposes, and it is still important to have the trust structured properly.
What happens to a first-party SNT if Medicaid never actually pays for long-term care and I pass away after only a few years?
Medicaid can only recover if it has actually paid for long-term care services for you while you were receiving Medicaid. If you never use Medicaid benefits, there is nothing for the state to recover from, and the remaining trust assets can pass to whoever your trust document designates as remainder beneficiaries. This is a potential advantage of a first-party SNT in some situations: you have the safety net of protected assets in case you need Medicaid, but if you do not need it, the assets can still benefit your heirs.
Can a trustee of a third-party SNT be a family member, or does it have to be a professional?
In most cases, a family member can serve as trustee of a third-party SNT, and many families prefer this arrangement. However, the trustee must understand the rules of government benefits and the provisions of the trust document, and they must be willing to make decisions that sometimes disappoint the beneficiary. Some families choose a professional trustee, or a combination of a family member and a professional co-trustee, to balance family involvement with professional expertise.
