The Trust Most Families Actually Need
If you’re a parent, grandparent, or family member planning ahead for someone with disabilities, a third-party special needs trust is almost certainly the tool you need. It’s the most common SNT type for family planning — and for good reason: no Medicaid payback.
Unlike a first-party trust (where the state gets reimbursed first), a third-party trust lets remaining funds pass to your other children, family members, or a charity of your choice. The money protects your child’s benefits during their lifetime, and what’s left stays in the family afterward.
This guide covers everything specific to third-party trusts — setup options, who can contribute, how to integrate with your estate plan, and the decisions that matter most. For the overview of all trust types, see our Complete SNT Guide.
How Third-Party Trusts Differ
| Feature | Third-Party SNT | First-Party SNT |
|---|---|---|
| Funded by | Anyone EXCEPT the beneficiary | The beneficiary’s own assets |
| Medicaid payback | No | Yes |
| Age limit | None | Under 65 at funding |
| Remainder beneficiaries | Your choice (siblings, family, charity) | State gets first claim |
| Established by | Anyone (parent, grandparent, friend, attorney) | Parent, grandparent, guardian, or court only |
| Sole benefit rule | Flexible — can include family benefit provisions | Strict — every dollar must solely benefit the individual |
Two Ways to Create One
Inter Vivos (Living) Trust
Created during your lifetime as a standalone document. It exists now and can receive funds immediately — gifts, life insurance assignments, investment accounts. This is the more flexible option:
- Can receive contributions from anyone at any time
- Avoids probate — assets go directly into the trust
- Can be the beneficiary of your life insurance policy right now
- Can be amended or revoked (if drafted as revocable) until your death
- Cost: $2,000–$5,000+ in attorney fees
Testamentary Trust
Created within your will — it doesn’t exist until you die. The will directs assets into the trust, which is established at that point.
- Lower upfront cost (part of your estate plan, not a separate document)
- Simpler if you’re not funding the trust during your lifetime
- Downside: Goes through probate, which means court involvement, public record, fees, and delays
- Downside: Can’t receive contributions from other people during your lifetime
- Cost: $1,500–$3,000 as part of a comprehensive will/estate plan
Recommendation: If you’re naming the trust as a life insurance beneficiary or want family members to contribute during your lifetime, go inter vivos. If the trust is only funded through your estate at death and you want to keep costs down, testamentary works.
Who Can Contribute
Anyone — and that’s the power of a third-party trust. Unlike ABLE accounts (one account, one annual cap), a third-party SNT can receive unlimited contributions from unlimited sources:
- Parents (life insurance, will, direct gifts)
- Grandparents (gifts, inheritance, birthday contributions)
- Siblings, aunts, uncles, friends
- Employers or community fundraisers
Contributions up to $18,000/person/year (2026) avoid gift tax reporting. Above that, the contributor files an informational gift tax return but likely owes no tax (lifetime exemption applies). See our Funding Strategies guide for details.
The one thing to never do: Don’t let the beneficiary’s own money go into a third-party trust. If the person with the disability deposits their own funds (savings, settlement, inheritance received directly), the trust may be reclassified as a first-party trust — triggering Medicaid payback. Keep the sources clean.
Estate Plan Integration
A third-party trust is only as effective as the estate plan surrounding it. Every document in your plan needs to point the same direction:
Your Will
Must direct any bequest to the trust, not to your child directly. Language matters — your attorney should reference the trust by its full legal name and date.
Life Insurance
Name the trust as beneficiary on any policy intended for your child. Not your child directly. Not “my estate.” The trust, specifically.
Retirement Accounts
Can name the trust as beneficiary, but tax treatment is complex. See our Funding Strategies guide for SECURE Act implications.
Other Family Members’ Plans
Grandparents, siblings, anyone who might leave your child money — their wills need to reference the trust too. One relative’s direct bequest can undo your entire plan.
Choosing Remainder Beneficiaries
One of the biggest advantages of a third-party trust: you decide where leftover funds go. Common choices:
- Siblings — most common; balances the financial focus on the child with disabilities
- Other family members — nieces, nephews, cousins
- Charity — disability organizations, your child’s service providers
- A secondary trust — for grandchildren or other future beneficiaries
Review remainder beneficiaries every few years. Family circumstances change — divorces, deaths, new children, estrangements. The trust should reflect your current wishes.
Frequently Asked Questions
Can a third-party trust be used alongside an ABLE account?
Yes — and this is the recommended approach for many families. The trustee can fund the ABLE account from the trust (within annual limits), giving the beneficiary debit-card independence for everyday expenses while the trust handles larger needs.
What happens if someone accidentally puts the beneficiary’s own money into a third-party trust?
This is a serious problem. Commingling first-party and third-party funds can cause the entire trust to be treated as a first-party trust, triggering Medicaid payback on all assets. If this happens, consult a special needs attorney immediately — the trust may need to be reformed.
Can I change the trustee or terms after the trust is created?
If the trust is revocable (during your lifetime), yes — you can amend it. After your death, or if it’s irrevocable, changes require a trust protector provision, court modification, or decanting (transferring to a new trust). A well-drafted trust includes a trust protector who can make necessary changes as laws evolve.
Is a third-party SNT the same as a supplemental needs trust?
The terms are often used interchangeably. “Special needs trust” and “supplemental needs trust” both refer to trusts designed to supplement government benefits. “Third-party” specifies who funds it. Your attorney may use either term.
