My question involves criminal law for the state of:Washington
So my fiance had (4 1/2 years ago) been online in a game and was talking sexual to minors. His ex wife had a software where she could keep an eye on him and what he was doing and says she has copies of some conversations between him and some minors or a minor (not clarified). Due to not liking me she wants to minimize there visitation and has been threating my fiance for years to use this. He signed to divorce and child support papers just how she wanted because she said she would get rid of them but now is throwing it in his face she is going to turn him in. How much trouble can he get in and can she also for black mail?
