My Boyfriend Was Falsely Accused Of Assault And Wants To Get It Expunged.

Hi, we live in Washington state. 3 years ago my partner was falsely accused of assault with sexual motivation by a family member. While the ‘victim’ did not wish to press charges, the state did. My boyfriend was told at the end of the case that the charges would be expunged.

Today we went to go pick up his papers saying his record is clean so he can join the military but we found out that the case was dismissed instead. The court said his attorney can help him get it expunged but when he called his attorney they stated that’s not something they do. He is worried he may not be able to join the military if this charge isn’t expunged. Any advice on what he could do?

Edit: court ordered him after the accusation to go to therapy which he completed and was discharged with a small diagnosis of anxiety disorder and we already picked up that paper from the therapists office.
