How to Plan for a Disabled Child’s Lifetime Care Without Losing Their Benefits

Reviewed by Attorney Kim Hegwood

Every parent of a child with a disability has the same conversation in their head, late at night, often for years before they have it with anyone else. Who’s going to take care of him when we’re gone? What happens to her when I can no longer drive her to her appointments, advocate for her at school, fight with her insurance company, manage her medications, sit with her on the hard days?

You’re not the first parent to have the conversation. You won’t be the last. And the planning that lets you actually answer the question — with documents and structures and a real plan, not just hope — exists. It’s been built and refined by parents and lawyers over decades, and it works.

The trap most families fall into isn’t a lack of love. It’s a lack of information. Parents naturally assume that leaving money to their disabled child is the right thing to do — the same way they’d leave money to any other child. For a disabled child receiving SSI, Medicaid, or other means-tested benefits, that ordinary inheritance often does the opposite of what the parents intend. The benefits get terminated. The medical coverage that pays for therapy, day programs, group home placement, and a lifetime of care disappears. The inheritance, no matter how generous, runs out faster than the parents could have imagined.

The plan that works is built around a simple insight: the inheritance has to supplement the benefits without replacing them. That’s the entire architecture of special needs planning, and once parents understand it, the rest of the work becomes manageable.

The Mistake That Costs Families Everything

It’s easier to start with what doesn’t work, because the same mistake shows up in family after family.

A parent dies. The will leaves “one-third of my estate to my daughter Sarah” — the disabled adult child, the one who’s been on SSI and Medicaid for fifteen years. The check arrives. Sarah’s bank account suddenly has $200,000 in it.

The next month, Sarah’s SSI benefits stop. The Texas Medicaid program follows. The day program she’s been attending for a decade tells the family she no longer qualifies for the funding that pays for her slot. The group home where she lives requires private pay starting next month — at $5,000 per month, paid out of the inheritance. Within three years, the $200,000 is gone. Sarah reapplies for benefits, but the requalification process takes months. During those months, she’s been moved out of her group home because no one is paying. Her care plan has been disrupted. Her routine, which took years to build, is broken.

The parents loved their daughter. They thought they were doing the right thing. The will their estate planning attorney drafted was technically valid. The disaster that followed was preventable.

What the parents needed wasn’t an ordinary will. They needed a third-party special needs trust — a specific kind of trust designed to hold inheritance assets for a disabled beneficiary without the beneficiary owning those assets directly. With a properly drafted special needs trust, the same $200,000 would have funded Sarah’s supplemental needs for years (extra therapies, recreation, vacations, equipment, things her benefits don’t cover) while she remained qualified for the SSI and Medicaid that pay for her core care.

The difference between the two outcomes isn’t the love behind the plan. It’s the structure.

What a Third-Party Special Needs Trust Actually Does

A third-party special needs trust is a trust funded with assets that never belonged to the disabled person — typically by parents, grandparents, or other family members through their own estate plan. The trust holds the assets, a trustee makes distributions for the beneficiary’s supplemental needs, and the beneficiary remains qualified for SSI, Medicaid, and other means-tested benefits because they don’t own the trust assets.

Three features distinguish a third-party SNT from other trusts:

The beneficiary doesn’t own the trust assets.

The trust does. The beneficiary has a beneficial interest — the right to receive distributions under the trust terms — but they cannot demand distributions, cannot direct how the assets are invested, cannot pledge the trust as collateral, and cannot have the trust assets attached by their creditors. For SSI and Medicaid eligibility purposes, the trust assets are not “countable resources” of the beneficiary.

The trustee has discretion over distributions.

The trustee decides what to pay for, when, and how. The standard authorizes payments for the beneficiary’s “supplemental needs” — anything that supplements but does not replace the benefits the beneficiary receives. The discretionary structure is essential; mandatory distributions would create a property right that benefits programs would treat as a countable resource.

No Medicaid payback at death.

Whatever’s left in the trust at the beneficiary’s death passes to the remainder beneficiaries the parents named — typically siblings, nieces and nephews, or charity. There’s no requirement to reimburse the state Medicaid program for benefits paid during the beneficiary’s lifetime. This is the critical distinction between third-party trusts (no payback) and first-party trusts (payback required); for most parents planning for a disabled child, the third-party structure is what they want.

The trust can pay for an enormous range of things that improve the beneficiary’s quality of life without disrupting benefits — supplemental medical care, dental care not covered by Medicaid, therapeutic services beyond what insurance covers, personal care attendants beyond Medicaid-funded hours, home modifications, recreation, vacations, technology, hobbies, pets and pet care, family visits when the beneficiary lives in a residential placement. The list is long. We cover the full breadth on our special needs planning practice page.

Coordinating the Trust With Everything Else That Has to Happen

A special needs trust on its own isn’t a plan. It’s the foundation of a plan. The full picture for parents of a disabled child involves coordinating several distinct pieces:

The will or revocable living trust has to direct the disabled child’s share of the parents’ estate into the special needs trust rather than to the child outright. This is the most commonly missed step — parents update the special needs trust but never update the will, and at the parents’ death the inheritance bypasses the trust and goes directly to the child anyway.

Beneficiary designations on retirement accounts, life insurance policies, annuities, and transfer-on-death accounts have to be redirected. These pass outside the will entirely and don’t automatically flow into the trust. We’ve seen many cases where the parents’ estate plan was updated correctly but the IRA beneficiary designation still named the disabled child directly — and at the parent’s death, the IRA paid the child outright, immediately disqualifying them from benefits.

Guardianship and supported decision-making have to be addressed before the disabled child’s 18th birthday. At 18, the child is a legal adult, and the parents lose the automatic legal authority they’ve had since birth. For some young adults with disabilities, full guardianship is the right answer. For others, a less restrictive option — limited guardianship, supported decision-making agreement, powers of attorney, or some combination — preserves the child’s autonomy where they have capacity while providing the legal authority where they need help. The decision is one of the most important in the family’s planning, and it has to be made before age 18.

A letter of intent — a non-legal document the parents prepare describing the child’s daily routine, medical history, behavioral triggers, communication preferences, food preferences, religious practices, friendships, sleep patterns, fears, and joys. The letter doesn’t have legal effect, but it gives the future trustee, guardian, and care providers the information they’ll need to step into the parents’ role. We provide a template and walk families through writing it. It’s often the most emotionally important document in the entire plan.

Sibling roles and expectations. Most parents of disabled children expect the child’s siblings to play some role after the parents are gone — sometimes as trustee, sometimes as guardian, sometimes as the family member who “checks in” and advocates. The expectations need to be discussed openly with the siblings while the parents are alive, and the legal documents need to reflect what the siblings have actually agreed to. Surprise responsibilities at the parents’ death are one of the most reliable sources of family conflict in special needs families.

Medicaid and waiver programs. Texas long-term services and supports for adults with disabilities are administered through several programs — STAR+PLUS, the Home and Community-Based Services (HCS) waiver, the Texas Home Living (TxHmL) program, the Community Living Assistance and Support Services (CLASS) waiver, and others. Many of these have years-long waiting lists. The application work often needs to start while the parents are still alive and able to advocate for placement. We coordinate this with the rest of the plan.

ABLE accounts for smaller, more flexible expenses. ABLE accounts let a person with a disability hold up to a defined amount of assets without affecting SSI or Medicaid eligibility, with the beneficiary themselves managing the account for qualified disability expenses. ABLE accounts complement special needs trusts rather than replace them — for most families, the right answer is both, with the trust holding the larger long-term assets and the ABLE account handling day-to-day flexibility.

Choosing the Right Trustee

The trustee question is the question that keeps most parents of disabled children awake at night. Who can possibly do this job for a beneficiary who may need lifetime care, when the parents themselves are gone?

The honest answer is that there’s no perfect option, only the best option for a particular family. The choices break down roughly as follows:

A sibling as trustee. Often the parents’ first instinct. Works well when the sibling has the financial sophistication, the geographic accessibility, the time, and the emotional stability to take on what may be a 30-year responsibility. Doesn’t work when those conditions aren’t met — and many siblings who agree to serve at the parents’ death find the role overwhelming within a few years. Sibling trustees often need professional support (a corporate co-trustee, a special needs attorney on retainer, a care manager) to do the job well.

A professional trustee. A bank trust department or independent trust company. Provides institutional continuity, technical expertise about benefits programs, and freedom from family conflict over distributions. Costs money — typically 0.5% to 1.5% of trust assets per year. Less personal connection to the beneficiary than a family member would have. Best for trusts of meaningful size where the institutional resources justify the cost.

A pooled trust. Administered by a nonprofit organization that serves multiple disabled beneficiaries (in Texas, The Arc of Texas Master Pooled Trust is the largest). Pools assets for investment efficiency while maintaining separate accounts for each beneficiary. Often the right choice for smaller funding amounts where the cost of an individually administered trust would be disproportionate.

A combined structure. A sibling and a corporate co-trustee, with division of responsibilities — the sibling handles the personal advocacy and judgment about distributions, the corporate trustee handles investments, accounting, tax filings, and benefits compliance. For many Texas families, this is the right answer.

A trust protector. Whoever the trustee is, the trust should also include a trust protector — a third party with the power to remove and replace the trustee, modify administrative provisions, and adapt the trust to changes in law. Without a protector, a 30-year trust can quickly become trapped under a trustee who isn’t serving the beneficiary well.

The trustee selection conversation is one we have with every family planning for a disabled child. The right answer depends on the family — and it often changes over time as siblings mature, as the parents’ wealth grows, and as the disabled child’s needs become clearer.
