Special Needs Trust Cost Washington — Third-Party, First-Party, and DDETF Options

What a Custom SNT Costs in Washington

A standalone special needs trust drafted by a Washington attorney typically runs $1,800 to $5,000, depending on complexity. As part of a comprehensive estate plan (which usually includes a will, powers of attorney, and the SNT together), expect $3,000 to $7,500 for a single parent or $7,500 to $20,000 for couples with multiple planning needs.

Ongoing costs include trustee fees if you name a professional trustee (typically 1% to 2% of trust assets annually), trust administration expenses, and periodic attorney reviews when laws change.

These costs put custom-drafted trusts out of reach for many families — particularly those whose total estate might be $50,000 or less. That's where pooled trusts and ABLE accounts fill the gap.

Third-Party vs. First-Party: The Payback Distinction

The single most important distinction in special needs trust planning is who funded the trust.

Third-party SNT — funded with money that was never the beneficiary's own assets. A parent sets up the trust with their own savings, life insurance proceeds, or inheritance. Because the beneficiary never owned the money, there is no Medicaid payback when they die. Remaining funds pass to other family members or beneficiaries named in the trust.

First-party (self-settled) SNT — funded with the beneficiary's own money: a direct inheritance, a personal injury settlement, or accumulated savings. Federal law (42 U.S.C. § 1396p(d)(4)(A)) requires a Medicaid payback provision. When the beneficiary dies, the state recovers Medicaid costs from remaining trust funds before any other distributions.

The practical implication: if a well-meaning relative leaves an inheritance directly to the individual with a disability — bypassing a trust — that money becomes the beneficiary's own asset. It can put SSI or Apple Health eligibility at risk if countable resources exceed the applicable limit; depending on the circumstances, a first-party SNT, DDETF first-party account, or WA ABLE account may help protect eligibility.

The DD Endowment Trust Fund (DDETF)

Washington's state-administered pooled trust offers an alternative for families who can't afford a custom-drafted trust. The DDETF pools investments across all enrolled beneficiaries for better returns and lower individual costs.

Key features:

• No minimum deposit (unlike custom trusts, which often require $10,000 or more to be cost-effective)
• No upfront attorney fees for trust drafting
• Professional trust administration included
• Annual account maintenance fees apply
• Funds can be used for qualified disability expenses that enhance quality of life

The DDETF handles both third-party and first-party sub-accounts. First-party accounts still carry the Medicaid payback requirement, but the trust administration is handled by the state program rather than requiring a private trustee.

The main limitation: distribution requests go through the DDETF program, which means less flexibility and slower disbursements compared to a privately administered trust. Families who need frequent, responsive distributions for daily needs may find the process cumbersome.

When Each Option Makes Sense

Many families use a combination: a WA ABLE account for accessible savings up to $100,000, and a third-party SNT for larger inheritance planning. The ABLE account handles routine qualified disability expenses, while the SNT preserves larger assets without Medicaid recovery exposure.

Washington's Expanded Estate Recovery

The trust planning urgency is amplified by Washington's estate recovery rules under WAC 182-527. Unlike most states, Washington recovers Medicaid costs from both probate and non-probate assets — including joint tenancy properties, payable-on-death accounts, and living trusts.

Any asset that passes outside a properly structured SNT is potentially exposed to recovery. A parent who adds their adult child as a joint tenant on a bank account, thinking it avoids probate complications, has actually expanded what the state can reach.
