州の概要

WA

Washington

The Estate Guide flags Washington as having a separate estate-tax system for 2026. Washington is a general community-property jurisdiction. These category flags are a research starting point, not a domicile, liability, filing, or trust-situs determination.

  • Use the Department of Revenue page for the decedent's exact date of death and current forms.
  • Community-property agreements can have broad transfer effects and should not be treated as a generic probate shortcut.
  • Washington estate-tax planning must be modeled separately from federal tax and portability.

  • Verify current will and power-of-attorney execution rules.
  • Check probate options and any county-specific procedure.
  • Review property outside the state and any trust with an out-of-state trustee.

検認手続きSuperior Court probate is governed principally by Title 11. Probate/nonprobate classification, venue, fiduciary appointment, creditor procedure, and county filing practice must be coordinated.Circuit Court probate under Oregon's probate code addresses appointment, notice, claims, inventory, accounting, and distribution. A simple-estate affidavit is a limited alternative, not a substitute for every estate.
少額遺産手続き$100,000 maximum net probate personal property under RCW 11.62.010; wait 40 days, no personal representative may be pending or appointed, and debts plus funeral expenses must be paid or provided for. Real property is not collected through this affidavit.A simple estate may include no more than $75,000 of personal property other than manufactured homes and no more than $200,000 combined real property and manufactured homes. ORS 114.515 generally requires a 30-day wait and the statutory affidavit and notice process.
信託法の環境RCW chapter 11.98 supplies Washington's core trust rules, with trust and estate disputes commonly handled under TEDRA, chapter 11.96A.ORS chapter 130 is the Oregon Uniform Trust Code and governs creation, administration, trustee duties, modification, creditor rights, adviser powers, and related proceedings.
永久拘束禁止原則、指示型信託、自己設定型資産保護信託、信託所得税Duration: RCW 11.98.130 supplies a 150-year permissible period for covered trusts, subject to its creation-date and statutory application rules. Direction: Yes. Washington's Uniform Directed Trust Act, chapter 11.98B RCW, allocates powers and duties between a trust director and directed trustee. DAPT: No broad domestic asset-protection trust regime for an ordinary self-settled beneficial interest is identified. RCW 6.32.250 protects qualifying trusts created by someone other than the debtor, so settlor access and creditor law require separate review. Income tax: As of this review, Washington has no current general individual or fiduciary net-income tax. Its capital-gains excise tax and ownership/attribution rules can still matter; Washington has announced a high-income individual tax beginning in 2028, so recheck before a situs change.Duration: Oregon generally uses the statutory lives-in-being plus 21 years or 90-year alternate vesting period in ORS chapter 105, subject to exclusions such as qualifying stewardship trusts. Direction: Yes, through Oregon's trust-adviser statute. ORS 130.735 permits a trust instrument to require direction or approval and limits a trustee's liability under the statute unless the trustee acts with reckless indifference or specified misconduct. DAPT: No broad DAPT regime for an ordinary self-settled interest. ORS 130.315 generally allows a settlor's creditor to reach the maximum amount distributable to or for the settlor, subject to statutory exceptions. Income tax: Oregon taxes resident trusts and Oregon-source income of nonresident trusts. Current Form OR-41 instructions treat trustee residence or Oregon administration as relevant to resident status, subject to the exact statutory and constitutional facts.
