The Washington Court’s 2016 official Domestic Violence Manual for Judges is available online at https://www.courts.wa.gov/index.cfm?fa=home.contentDisplay&location=manuals/domViol/index.
It is available as a searchable series of web pages and as one PDF file for downloading.
The DV manual is a bit disorganized since it is written by a series of authors, but overall it is a fairly comprehensive review of domestic violence. It has not been updated to include information about Washington’s new domestic violence law in RCW 7.105, which was adopted in July 2022.
It does talk about coercive control, but not as defined in RCW 7.105. Washington’s new law allows for people to obtain a protection order based on coercive control which does not involve physical violence. However, the concept of coercive control has been around for many years and the 2016 Judge’s DV Manual references the concept.
