E-signature laws in Washington
Washington state is notable for being one of the very last states to formally adopt UETA, doing so in 2020. Prior to 2020, Washington had its own Electronic Authentication Act (RCW 19.34) dating from 1996, which provided e-signature validity under a different framework. The 2020 UETA adoption standardized Washington's law with national norms. As home to Amazon, Microsoft, and a dense technology industry, Washington's late adoption was somewhat ironic — but e-signatures were legally valid throughout under both the prior state law and the federal ESIGN Act.
Washington Uniform Electronic Transactions Act (RCW § 19.360.010–19.360.902) (2020)
Key provisions
- Electronic signatures are legally valid and enforceable, with the same legal effect as handwritten signatures.
- A contract or signature may not be denied legal effect solely because it is in electronic form.
- Parties must consent — expressly or impliedly — to conduct a transaction electronically.
- Electronic records satisfy any Washington statute or rule requiring information to be in written form.
- Washington's prior Electronic Authentication Act (RCW 19.34) was superseded by UETA in 2020, unifying the framework.
What you can't e-sign in Washington
- Wills, codicils, and testamentary trusts — require formal execution under RCW 11.12 with witnesses.
- Documents governed by UCC Articles other than 2 and 2A.
- Court orders, judicial records, and official court documents requiring wet signatures.
- Certain consumer protection notices required under Washington Consumer Protection Act (RCW 19.86).
Practical tips for Washington
- Washington's technology companies have long used e-signatures despite the late UETA adoption — the federal ESIGN Act covered interstate transactions since 2000.
- Washington authorized remote online notarization (RON) in 2020, coinciding with UETA adoption — use a Washington-approved RON platform for notarized documents.
- Seattle's competitive real estate market makes electronic contracts essential — Washington real estate purchase and sale agreements (PSAs) can be e-signed.
- For technology company agreements in Seattle or Redmond (Microsoft/Amazon corridor), include clear consent-to-electronic-signature clauses in SaaS terms and enterprise agreements.
