When parents plan for a child with a disability, most of the attention goes to the trust itself. But the person you name to run that trust matters just as much. Choosing a special needs trust trustee in Missouri and Kansas means picking someone who will manage money carefully, understand how public benefits work, and keep your loved one’s quality of life at the center of every decision, possibly for decades after you are gone.

Here is what the job involves, the benefit rules a trustee has to work around, and some practical ways to think about who should serve.

What Is a Third-Party Special Needs Trust?

A third-party special needs trust (sometimes called a supplemental needs trust) holds money or property that never belonged to the person with a disability. Parents, grandparents, siblings, and other relatives commonly fund it during life or at death through a will, a living trust, life insurance, or beneficiary designations. Because the trust, not the beneficiary, owns the assets, a properly written trust can provide extra support without counting against the beneficiary’s eligibility for needs-based programs like Supplemental Security Income (SSI) and Medicaid (MO HealthNet in Missouri, KanCare in Kansas).

This is different from a first-party special needs trust, which holds the beneficiary’s own money, such as a lawsuit settlement or an inheritance left to them outright. First-party trusts generally must repay the state Medicaid program from what is left when the beneficiary dies. A third-party trust does not carry that payback requirement, so remaining funds can pass to other family members you choose. For a broader overview, see our article on special needs trusts in Missouri and Kansas.

What Does a Special Needs Trust Trustee Do?

A trustee is a fiduciary. That means they must manage the trust honestly, carefully, and for the beneficiary’s benefit, following the trust’s terms. Missouri’s trust code requires a trustee to administer the trust in good faith and in line with its terms and purposes (RSMo 456.8-801). Both states also require trustees to keep certain beneficiaries reasonably informed and, in general, to provide annual reports of trust property, receipts, and payments (RSMo 456.8-813; K.S.A. 58a-813).

Day to day, a special needs trust trustee usually handles:

• Deciding when and how to make distributions for the beneficiary
• Investing trust assets prudently
• Keeping clear records and receipts for every payment
• Filing the trust’s income tax returns, such as IRS Form 1041, when required
• Communicating with the beneficiary, family members, caregivers, and benefits agencies

The Consumer Financial Protection Bureau publishes a free, plain-language guide for trustees that walks through these duties and is worth sharing with anyone you are considering.

How Special Needs Trust Distributions Affect SSI and Medicaid

This is where a well-meaning trustee can make costly mistakes. According to the Social Security Administration’s SSI Spotlight on Trusts:

• Cash paid directly to the beneficiary reduces their SSI benefit.
• Payments for shelter (such as rent or a mortgage) also reduce SSI, but only up to a capped amount each month, which SSA lists as $351.33 for 2026.
• Payments for other things, such as medical care, phone bills, education, and entertainment, paid directly to the provider, do not reduce SSI.

One rule changed recently. Since September 30, 2024, SSA no longer counts food as in-kind support, so a trust paying for groceries no longer reduces SSI. Older articles and some trust documents still describe the former rule, so it is worth reviewing with your attorney how your trust and your trustee handle these payments.

SSI also has a strict resource limit of $2,000 for an individual, so a trustee should be cautious about payments that could leave the beneficiary holding countable assets. And SSA itself notes that some trust payments it ignores can still affect Medicaid, so Missouri and Kansas Medicaid rules need to be checked separately. In some cases, an ABLE account can work alongside the trust to give the beneficiary a little more flexibility.

Should a Family Member or a Professional Be the Trustee?

There is no single right answer. Families in Missouri and Kansas often weigh options like these:

• A trusted family member. They know your loved one well and usually serve for little or no fee. The tradeoff is that they may have limited experience with investments, tax filings, and benefit rules, and they may face family pressure. A family trustee can hire an attorney or accountant, and reasonable professional fees can typically be paid from the trust.
• A professional or corporate trustee. A bank trust department or professional fiduciary brings experience, continuity, and recordkeeping systems. Fees are higher, and they may not know your loved one personally.
• Co-trustees. Some families pair a family member, who knows the beneficiary’s needs and preferences, with a professional who handles investments and compliance.

Whoever you choose, also name at least one successor trustee. If no successor is named and the trustee can no longer serve, a court may have to step in to appoint someone. Our article on how to choose a trustee offers more questions to ask.

Questions to Ask Before Naming a Special Needs Trust Trustee in Missouri or Kansas

• Will this person likely be able to serve for the beneficiary’s lifetime, or do I need a strong backup plan?
• Are they organized and comfortable keeping detailed records?
• Will they ask for help when the rules are unclear instead of guessing?
• Do they have a good relationship with my loved one and with the rest of the family?
• Would a co-trustee or a trust protector add helpful oversight?

It also helps to leave a letter of intent that describes your loved one’s routines, medical providers, likes and dislikes, and your hopes for their future. A trustee who knows what matters to your family is better able to make decisions you would agree with.
