I wish a knew a 'good' lawyer. Mine was a total flake. WA sucks when it comes to shit like this. I ended up getting sole custody of my boy, but it took CPS, multiple records of police reports and arrests of her, and lots of documentation for the court to even consider it. The parenting plan is a joke for silly women who think children are possessions. Just keep your nose clean and dont make a SINGLE mistake during this and you will come out ok.
FWIW, in this state if you have a GF that has been living with you for 6 mos. with her child (does not need to be yours) if you break up, you will be liable for child support.
