Will my wife find out I was arrested for soliciting a prostitute?

I don't think the court or police customarily notify spouses of arrest. I just think with the mail you will be receiving it will be tough to hide I, that is if the case goes to the court of common pleas level and your are eventually put on probation. Plus, a lot of times the cases are published in the local papers. Your best bet is to hire an attorney who can get this things resolved at the preliminary hearing level and put it to rest. In Allegheny county for first time offenders they offer "johnny classes" if you go to one of these and complete it the charge is withdrawn or reduced to a summary. That way the case ends at the DJ level and there is no probation.
