The short answer
If someone you love receives means-tested benefits, leaving them money directly can do real harm. Benefits like Supplemental Security Income and Medicaid depend on what the person owns and receives, and an inheritance counts.
The standard answer is a special needs trust, sometimes called a supplemental needs trust. The trust holds the money, a trustee spends it on that person's behalf, and because the person does not own or control the funds, the trust is structured so their eligibility is not disrupted. This article explains the shape of the solution. The drafting itself belongs with an attorney who does this work, and our comparison of the two paths is in do I need a lawyer to make a will.
Why good intentions backfire
Consider Ana, whose adult son Luis has a developmental disability and receives benefits that cover his medical care and part of his housing. Ana's will divides her estate equally between Luis and his sister.
When Ana dies, Luis's share lands in his name. Those assets are his, and they count against him. Benefits he has had for twenty years can be interrupted. The money then gets spent covering the services the benefits used to cover, often faster than anyone expected, and when it runs out the family has to start the application process again from zero.
Ana was trying to be fair. The fair result would have been a trust holding Luis's share so that the money adds to his support instead of replacing it.
Benefit rules include specific asset limits and program requirements. This article does not state those figures, because they change and they differ by program and state. Get current numbers from the relevant agency or from an attorney who practices in this area.
What a special needs trust actually does
The core idea is separation. The money belongs to the trust, not to the person with the disability. A trustee decides what to buy and pays vendors directly rather than handing over cash. Because the beneficiary cannot demand the money, it is not treated as their resource.
What the trust pays for is described as supplemental: things that improve quality of life beyond what benefits already provide.
- Therapies, equipment, and care that benefits do not cover
- Education, training, and technology
- Travel, hobbies, and the companionship that makes a life feel like a life
- Furniture, electronics, and personal items
- Transportation, including a vehicle held for the beneficiary's use
Some categories of spending, particularly food and shelter, are treated differently by benefit programs and can reduce benefits even when paid by a trust. A trustee needs to understand those rules before writing checks, which is another reason the trustee choice matters.
Trusts funded by you versus trusts funded by the beneficiary
There is an important distinction, and it comes down to whose money went in.
A trust you fund with your own assets for someone else's benefit is generally called a third-party special needs trust. It is the one most families use for inheritance planning, and it has more flexibility, including the ability to say who receives anything left over when the beneficiary dies.
A trust funded with the beneficiary's own money, for example a personal injury settlement or an inheritance that was already received outright, is a first-party trust. First-party trusts carry additional requirements and restrictions that third-party trusts do not, including rules about what happens to remaining funds. The details are specific and statutory, so this is squarely attorney territory.
Choosing a trustee
The trustee is the person who makes this work in practice. They will be managing money, coordinating with care providers, keeping records, and understanding how spending interacts with benefits. That is a real job, often for decades.
Families commonly name a sibling or close relative who knows the beneficiary, sometimes paired with a professional trustee or a pooled trust organization that handles the administrative side. A relative who loves the person but has never managed an account is not automatically the right choice, and saying so out loud is not disloyal.
- Name a primary trustee and at least two successors, because this trust may outlive your first choice
- Consider pairing a family member with a professional or nonprofit co-trustee
- Write down the beneficiary's routines, preferences, providers, and history in a letter of intent
- Tell the trustee, in advance, that you are naming them and what the role involves
- Revisit the choice every few years as people age and circumstances change
Tell the rest of the family
Grandparents, aunts, uncles, and godparents write wills too, and a well-meant gift from any of them can cause the same problem your planning was designed to avoid.
Once the trust exists, let relatives know that gifts and bequests intended for your loved one should be directed to the trust by name rather than to the person. This is a short conversation that protects the whole structure. The same goes for beneficiary forms: no retirement account or life insurance policy should name the person with a disability directly if the plan is to route assets through the trust.
Beneficiary forms override your will. If any account still names the beneficiary personally, the trust never sees that money. Our explainer covers how beneficiary forms override a will.
What Estateur can and cannot do here
Estateur is a self-help document preparation service, not a law firm, and using our product creates no attorney-client relationship. We prepare wills, revocable living trusts with pour-over wills, financial powers of attorney, and healthcare documents for all fifty states and the District of Columbia. Those core documents are a real part of your plan and most families with a loved one with a disability need them regardless.
We do not draft special needs trusts. We are saying that plainly because the honest answer matters more than the sale. A special needs trust has to be drafted by someone who works with benefit rules regularly, and a generic form is worse than no trust at all here.
A reasonable sequence
If you are starting from nothing, this order tends to work well.
- Find an attorney in your state who practices special needs planning, and have the trust drafted
- Once the trust exists, make sure your will and any revocable trust direct your loved one's share into it by name
- Update every beneficiary form so nothing pays the person directly
- Ask family members to do the same in their own documents
- Write the letter of intent, and keep it with the trust documents
- Review the whole set every few years, or sooner if benefits or care arrangements change
For the documents in steps two and three, you can start your plan, and there is more on how a revocable living trust works.
