For a trust to be valid in Washington, it must meet the requirements in RCW 11.98.011: the trustor has legal capacity, clearly intends to create a trust, transfers identifiable property into it, names ascertainable beneficiaries, gives the trustee real duties to perform, avoids a complete merger of sole trustee and sole beneficiary, and serves a lawful purpose. Two other rules trip people up. Washington presumes every trust is irrevocable unless the document expressly says otherwise, and even a perfectly drafted trust controls nothing until you actually retitle assets into it.
The Seven Elements of a Valid Trust
RCW 11.98.011 sets the bar. Miss any one of these and the trust fails.1Washington State Legislature. Washington Code 11.98.011 – Trust Creation Requirements
- Capacity. The trustor (also called the settlor) must have the mental capacity to create a trust. That means understanding what you own, who your beneficiaries are, and what the trust is supposed to do.
- Intent. You must clearly express an intention to create a trust. A wish that someone “look after” your property is not enough; the document has to show you meant to create a binding legal arrangement.
- Identifiable property. A trust needs actual assets. Without property, sometimes called the corpus or principal, there is nothing for the trustee to manage.
- Ascertainable beneficiaries. The people or organizations who will benefit must be identifiable, either now or at some determinable future point. Washington also permits trusts for the care of an animal or for specific non-charitable purposes, even though those lack traditional beneficiaries.
- A trustee with duties. The trustee must have real responsibilities to carry out. A trust where the trustee owes nothing to anyone is not a trust.
- No complete merger. The same person cannot be both sole trustee and sole beneficiary. When one person holds both roles, the legal and beneficial interests collapse into ordinary ownership.
- Lawful purpose. The trust’s purpose cannot violate law or public policy. A trust designed to defraud legitimate creditors, for example, will not survive a challenge.
Drafting problems on capacity, intent, or purpose are relatively rare in practice. The failure that shows up again and again is a signed trust with nothing in it because the trustor never got around to funding it.
Washington Presumes Trusts Are Irrevocable
Under RCW 11.103.030, if the trust document does not expressly state that the trust is revocable, the trustor cannot revoke or amend it.2Washington State Legislature. Washington Code 11.103.030 – Revocation or Amendment This is the opposite of what many people expect, and the opposite of the rule in states that follow the Uniform Trust Code’s default of revocability. If you intend to keep the ability to change your trust later, the document itself must say so in clear terms.
The choice shapes almost everything downstream. A revocable trust lets you change beneficiaries, move assets in and out, or dissolve the trust entirely during your lifetime. In exchange, the IRS treats the assets as still yours, so a revocable trust does not reduce your taxable estate. An irrevocable trust generally removes assets from your estate for tax purposes, but you give up control. Silence in the document defaults you to irrevocable, which is often not what people want.
How the Document Must Be Executed
Washington recognizes oral trusts only in limited situations, and their existence and terms must be established by clear, cogent, and convincing evidence.3Washington State Legislature. Washington Code Chapter 11.98 – Trusts Trusts involving real estate must be in writing under the statute of frauds, and any serious estate plan belongs in a written instrument regardless of what the trust holds.
A written inter vivos (lifetime) trust must be signed by the trustor. Washington does not require witnesses for a standard lifetime trust. A testamentary trust, created through a will, is different: it must meet the execution requirements for a will, meaning it must be signed by the testator and attested by at least two competent witnesses.4Washington State Legislature. Washington Code 11.12.020 – Requisites of Wills
Notarization is not strictly required for a living trust, but it is standard practice. A notary’s acknowledgment independently verifies the signer’s identity and confirms the signing was voluntary, which makes the trust much harder to challenge later on forgery or coercion grounds. Washington caps notary fees at $15 for an in-person acknowledgment and $25 for a remote notarial act.5Washington State Legislature. Washington Administrative Code 308-30-220
Funding the Trust
Signing the document is half the job. A trust has no effect on assets that have not been retitled into it. An unfunded trust is a valid legal document that controls nothing, and this is where most Washington trusts fall apart.
Real Estate
Transferring real property into a trust means recording a new deed, usually a quitclaim deed, with the county auditor’s office, with the trust named as the new owner. If the property carries a mortgage, check with the lender first. Federal law generally prevents lenders from calling a loan due solely because of a transfer to a revocable trust for estate planning purposes, but confirming avoids surprises.
Transferring real property into a revocable trust is exempt from Washington’s real estate excise tax. The transfer qualifies as a “mere change in identity or form of ownership” because the trustor retains the same beneficial interest.6Washington State Legislature. Washington Administrative Code 458-61A-211 You will still pay the county recording fee, which in Washington often runs several hundred dollars once state and local surcharges are added to the base fee.
Financial Accounts and Other Assets
Bank accounts, brokerage accounts, and certificates of deposit are transferred by retitling them in the trust’s name. Most banks want to see a copy of the trust or a certification of trust, and many will close the existing account and open a new one under the trust. For investment accounts holding stock or bond certificates, the broker handles the reissuance. Non-qualified annuities can also be retitled.
Retirement accounts are the important exception. IRAs and 401(k)s should not be transferred into a trust directly because doing so triggers immediate taxation. If a trust fits your plan, you name it as beneficiary of the retirement account instead of retitling the account itself.
Who Can Serve as Trustee
Washington allows any suitable person over age 18 to serve as trustee, along with trust companies organized under state law and national banks authorized to act in a trust capacity.7Washington State Legislature. Washington Code 11.36.021 – Trustees Who May Serve Many trustors serve as trustee of their own revocable trust while alive and name a successor to step in on incapacity or death.
A trustee owes fiduciary duties to the beneficiaries. The two central ones are loyalty and prudence. Loyalty means putting the beneficiaries’ interests ahead of the trustee’s own and avoiding self-dealing. Prudence means managing trust assets with reasonable care and skill, balancing safety of principal against income and growth. Both duties are enforceable, and a trustee who violates them can be held personally liable.
The trustee also has to keep beneficiaries reasonably informed about administration, respond to reasonable requests for information, and provide a copy of the trust when asked. Silence is one of the fastest routes to litigation.
Name a successor trustee in the document, and ideally a backup successor. If the trust names one, the successor is considered to have accepted the role as of the date the prior trustee’s discharge takes effect.8Washington State Legislature. Washington Code 11.98.039 – Nonjudicial Change of Trustee Without a named successor, interested parties can agree on a replacement through a nonjudicial agreement, or any beneficiary, the living trustor, or the current trustee can petition the superior court. The court route is slower and more expensive, which is the whole reason to name a successor up front.
Amending or Revoking the Trust
If the trust is expressly revocable, follow whatever method the document itself describes. When the document does not specify a method or does not make its method exclusive, you can amend or revoke through a signed written instrument showing your intent, or through a later will or codicil that expressly refers to the trust.2Washington State Legislature. Washington Code 11.103.030 – Revocation or Amendment
Marriage complicates the mechanics. When a revocable trust holds community property, either spouse can revoke acting alone, but amending it requires both spouses to act together. For separate property contributed by different trustors, each trustor can only revoke or amend the portion attributable to their own contribution. If one spouse revokes or amends without the other’s involvement, the trustee must promptly notify the other spouse.
If the trustor becomes incapacitated, an agent under a power of attorney can exercise the trustor’s revocation or amendment powers, but only if the power of attorney specifically authorizes it. A court-supervised conservator can act only with court approval.
Registration and Tax Identification
Washington does not require private trusts to register with a court or government agency. The document governs administration, and courts only get involved on a dispute. Charitable trusts that hold income-producing assets above a threshold set by the secretary of state are the narrow exception and must register with that office.9Washington State Legislature. Washington Code 11.110.051 – Registration of Trustee Requirements
An irrevocable trust is a separate taxable entity and needs its own Employer Identification Number from the IRS. The trustee uses that number to open bank accounts in the trust’s name and to file the annual return on Form 1041.10Internal Revenue Service. Taxpayer Identification Numbers (TIN) A revocable trust uses the trustor’s own Social Security number while the trustor is alive, because the IRS treats the trustor as the owner. When the trustor dies and the trust becomes irrevocable, the successor trustee obtains an EIN at that point.
Washington’s Estate Tax Sets the Stakes
Washington levies its own estate tax with a filing threshold far below the federal exemption. For deaths in 2026, the Washington threshold is $3,076,000.11Washington Department of Revenue. Estate Tax Tables The federal basic exclusion for 2026 is $15,000,000.12Internal Revenue Service. What’s New – Estate and Gift Tax A Washington estate well below the federal radar can still owe substantial state tax.
Rates begin at 10% on the first $1,000,000 of taxable value above the exclusion and climb to 35% on amounts over $9,000,000.11Washington Department of Revenue. Estate Tax Tables For married couples, a properly structured trust can make sure each spouse’s exclusion is actually used rather than wasted when the first spouse’s estate passes to the survivor under the marital deduction. That gap between state and federal thresholds is the reason many Washington families set up a trust in the first place.
Typical Costs
Attorney fees for drafting a living trust in Washington typically run $1,500 to $3,000 for a straightforward estate. Complex situations involving business interests, blended families, or significant real estate can cost more. Many attorneys bundle the trust with a pour-over will, power of attorney, and healthcare directive.
Beyond attorney fees, expect recording fees when moving real property into the trust. Between the base fee and Washington’s state and local surcharges, a single deed often runs a few hundred dollars, depending on the county. Notarization is capped at $15 per in-person acknowledgment and $25 for a remote notarial act.5Washington State Legislature. Washington Administrative Code 308-30-220 Small numbers compared to the probate fees and delays a fully funded trust is meant to avoid.
