Washington State's Change Order Law

ASA of Washington created a White Paper on Change Order Law, better known as the Prompt Payment Act, that once pertained only to public projects. The law changed in 2024 and is still being interpreted in the courts.

This white paper was edited by Saki Yamada with Ahlers, Cressman and Sleight LLC and distributed during an ASA-WA Lunch & Learn on Sept. 9, 2025.
