Arizona Special Needs Trust

Why Asset Protection Matters at 18

When your child turns 18, their financial life separates from yours by law. If they receive SSI, they're subject to an individual resource limit — countable assets above that amount can disqualify them from benefits. An inheritance, a personal injury settlement, or even accumulated birthday gifts in a savings account can push them over.

A special needs trust (SNT) holds assets on behalf of a person with a disability without those assets counting against the SSI resource limit. The trust pays for supplemental needs — things SSI and AHCCCS don't cover — while the beneficiary's public benefits stay intact.

First-Party vs. Third-Party Trusts

Arizona recognizes both types, and they serve different situations:

First-party (self-settled) SNT holds the beneficiary's own money — a personal injury settlement, an inheritance received directly, or back-pay from a benefits award. Under federal law (42 U.S.C. § 1396p(d)(4)(A)), the trust must be established by a parent, grandparent, legal guardian, or the court. The beneficiary cannot set it up themselves, even though it holds their money. The critical tradeoff: when the beneficiary dies, any remaining funds must first reimburse the state for Medicaid/AHCCCS expenditures before passing to other beneficiaries.

Third-party SNT holds money contributed by anyone other than the beneficiary — parents, grandparents, other family members. Parents can set this up in their own estate plan, naming their disabled child as beneficiary. The key advantage: no Medicaid payback requirement. When the beneficiary dies, remaining funds pass to whoever the trust document specifies.

For most disability families planning at 18, the third-party SNT is the right vehicle. It lets parents and grandparents contribute to a protected fund that supplements their child's life without the payback obligation hanging over it.

The $10,000 Threshold and Conservatorship

Under A.R.S. § 14-5312(A)(3), a court-appointed guardian can manage up to $10,000 per year of a ward's funds without a separate conservatorship. But if the ward's income or assets exceed $10,000 annually — from wages, settlements, or any source outside Social Security benefits — a conservatorship under A.R.S. § 14-5401 becomes legally required for court-supervised financial management.

A special needs trust sidesteps this entirely. Assets held in the trust aren't managed by the guardian — they're managed by the trustee, under the terms of the trust document. This means a family can hold substantial assets for their adult child's benefit without triggering the conservatorship requirement, its annual accountings, or its surety bond premiums.

When a STABLE Account Is Enough

Not every family needs a trust. Arizona's STABLE program (the state's ABLE-eligible savings plan) offers similar asset protection with far less complexity:

• No attorney needed to set up
• No trustee required
• Account holder controls their own money
• Tax-free growth and withdrawals for qualified expenses

The limitations: annual contributions cap at $20,000 ($35,650 if the account holder works and doesn't have an employer retirement plan), and SSI suspends when the balance crosses $100,000. AHCCCS eligibility continues regardless of the balance.

If your family's asset protection needs stay under these limits — you're managing ongoing income, not a lump-sum settlement — a STABLE account is simpler and cheaper. If the numbers exceed those boundaries, a special needs trust is the appropriate tool.

Many families run both: a STABLE account for accessible day-to-day disability expenses and a third-party SNT for larger assets that would breach the $100,000 SSI threshold.

Getting a Trust Drafted

Unlike a STABLE account or a power of attorney, a special needs trust requires an attorney. The trust document must comply with both federal Medicaid rules and Arizona trust law, and an improperly drafted SNT can be treated as a countable resource — defeating the entire purpose.

Look for an attorney who specializes in special needs estate planning, not a general practitioner who "also does trusts." The trust must be tailored to your family's benefit structure — SSI, AHCCCS, DDD services — because distributions that duplicate what those programs provide can reduce or eliminate benefits.
