Yes, a person with a mental illness can inherit property. No law bars someone from receiving an inheritance based on a psychiatric diagnosis or cognitive condition, whether the gift comes through a will or through intestacy when a relative dies without one.1Legal Information Institute. Intestacy Receiving an inheritance is passive. Unlike writing a will, which requires testamentary capacity, accepting one requires no legal capacity at all.
The hard part comes after. If the beneficiary relies on means-tested government benefits, an outright inheritance can knock them off those programs within weeks. And if their illness affects money management, an unstructured lump sum can vanish before anyone notices. Both risks are solvable, but only with the right structure in place.
Why an Outright Inheritance Can Be Dangerous
Many people with serious mental illness depend on Supplemental Security Income and Medicaid. Both programs cap what a recipient can own. For SSI, the countable resource limit is just $2,000 for an individual.2Social Security Administration. Spotlight on Resources An inheritance of any real size will blow through that limit almost immediately.
The Social Security Administration treats an inheritance as unearned income in the month the beneficiary can access it, and as a countable resource every month after that.3Social Security Administration. POMS SI 00830.550 – Inheritances If the money isn’t sheltered or spent down within that first month, SSI stops. Medicaid often stops with it, and Medicaid is what typically pays for mental health treatment, medication, and supportive housing.
A well-meaning bequest of $10,000 or $50,000 can end the benefits a person needs to function. That is the core reason families use the planning tools below.
The Best Case: A Third-Party Special Needs Trust
When a family is planning ahead, the strongest tool is a third-party special needs trust. Someone other than the beneficiary, usually a parent or grandparent, sets it up and funds it with their own assets. Because the money was never the beneficiary’s property, and because the beneficiary cannot revoke the trust or demand distributions, the SSA does not count it as a resource.4Social Security Administration. POMS SI 01120200 – Information on Trusts
The trust document should state that it exists to supplement, not replace, government benefits. The trustee pays vendors and service providers directly for things public benefits don’t cover: specialized therapy, education, recreation, electronics, transportation, personal care. Handing cash to the beneficiary would create countable income and defeat the purpose.
A key advantage over other options is that third-party trusts carry no Medicaid payback. When the beneficiary dies, whatever is left passes to the people the trust names, typically other family members. Nothing is clawed back by the state. That is why this is the preferred vehicle whenever a relative is leaving assets through their estate plan.
When the Inheritance Has Already Arrived
Sometimes the money lands in the beneficiary’s hands before anyone knew to plan. Two federally authorized options can still shelter it.
First-Party Special Needs Trust
A first-party special needs trust holds the beneficiary’s own money, including an inheritance they’ve already received. Federal law allows this for a person who is disabled and under age 65, and the trust must be established by a parent, grandparent, legal guardian, or a court.5Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets
The trade-off is a Medicaid payback provision. When the beneficiary dies, funds left in the trust must first reimburse the state for Medicaid benefits paid during the beneficiary’s lifetime.5Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets Only after that reimbursement does anything remaining pass to other beneficiaries. That is still far better than losing SSI and Medicaid outright.
Pooled Trust
A pooled trust works similarly but is administered by a nonprofit. Each beneficiary has a separate account within the trust, and the nonprofit pools all accounts for investment purposes. Pooled trusts can hold the beneficiary’s own assets, and there is no age restriction, which makes them a critical option for beneficiaries over 65.5Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets When the beneficiary dies, remaining funds are either retained by the nonprofit or used to reimburse the state. A pooled trust is also a practical choice when no family member is willing or able to serve as trustee.
ABLE Accounts as a Supplement
An ABLE (Achieving a Better Life Experience) account is a tax-advantaged savings account for people with disabilities. As of January 1, 2026, a person qualifies if their disability began before age 46, up from the previous cutoff of age 26.6ABLE National Resource Center. The ABLE Age Adjustment Act Fact Sheet The first $100,000 in an ABLE account is disregarded for SSI resource calculations.7Social Security Administration. Spotlight on Achieving a Better Life Experience (ABLE) Accounts
The catch is the contribution cap. For 2026, total contributions from all sources are limited to $19,000 per year.8Social Security Administration. SSA POMS SI 01130740 – Achieving a Better Life Experience (ABLE) Accounts A large inheritance cannot be dropped in all at once. That makes ABLE accounts a useful companion to a special needs trust rather than a substitute. A trustee might move $19,000 a year from the trust into the ABLE account, giving the beneficiary more direct control over a portion of funds. Note that when the account holder dies, remaining funds may be subject to a Medicaid payback claim for benefits paid after the account was opened.7Social Security Administration. Spotlight on Achieving a Better Life Experience (ABLE) Accounts
When Judgment Is the Concern, Not Benefits
Some beneficiaries with mental illness don’t rely on SSI or Medicaid, but their illness still affects spending decisions. A discretionary trust addresses that. The trustee has complete authority over whether, when, and how much to distribute, and the beneficiary has no legal right to demand payments.9Legal Information Institute. Discretionary Trust The structure protects the assets from creditors and prevents a beneficiary in a manic or unstable period from draining the account. The grantor picks someone they trust to make sensible calls based on real needs.
When Nothing Was Set Up: Conservatorship
If an inheritance passes outright to someone who cannot manage their own finances, and no trust or power of attorney exists, the probate court gets involved. The court can appoint a conservator of the estate, called a guardian of the property in some states, to manage the inherited assets. A family member usually petitions the court and shows that the proposed conservatee cannot handle their own financial affairs.
The court typically appoints an independent attorney or investigator to evaluate the situation and represent the proposed conservatee. If the petition is granted, the conservator takes control of the assets, owes a fiduciary duty to manage them prudently for the beneficiary’s welfare, and must file regular accountings with the court.
Conservatorship is expensive and slow. Filing fees, attorney costs on both sides, investigator fees, and ongoing court reporting add up quickly. It also strips the person of significant autonomy, which is why most estate planning attorneys treat it as a last resort. A durable power of attorney signed while the person still had legal capacity, with language broad enough to cover trust and investment management, can let a trusted agent handle inherited assets without going to court.
Picking the Right Trustee
Choosing the trustee matters as much as choosing the trust. A trustee who doesn’t know government benefit rules can disqualify the beneficiary with a single badly timed distribution, like writing a check directly to them instead of paying a vendor. Family members often serve, but many lack the financial and legal knowledge the role demands. Professional and corporate trustees bring expertise but charge fees, typically 1% to 2% of trust assets annually for larger trusts. Some families combine both: a relative who understands the beneficiary’s personal needs paired with a professional who handles investments and compliance.
Whatever the arrangement, name at least one successor trustee in the document. A trust that outlives its trustee with no named replacement will require court intervention to appoint one, which is exactly the delay and expense the trust was built to avoid.
