Tacoma Law and Evidence Compliance
The same Washington privacy, recording, and evidence rules apply in Pierce County, but local court expectations at the County-City Building and the density of JBLM-connected cases add practical compliance considerations that generic statewide guidance may not address.
RCW 9.73.030 - Recording Law
Washington's two-party consent rule for recording private conversations. This is why we don't record calls without proper authorization.
RCW 26.09 - Dissolution
The core statute for divorce, support, and family-law proceedings in Washington - the legal framework most of our investigations connect to.
RCW 26.09.191 - Parenting Restrictions
The statute that addresses parenting plan restrictions when domestic violence, abuse, neglect, or substance abuse is involved. This is often relevant to our custody and guardianship investigations.
