Thank you for the information and your question. Forgery, which is what you described, is considered a Class H felony in Wisconsin and is punishable by up to 6 years in prison and fines of $10,000. So, technically, you could be charged with a separate felony count for each check you took and forged. You could also be charged with fraud for writing the check to whoever you wrote it to, which could be charged as a felony or a misdemeanor
So, if you are still on probation, you will likely be arrested for violation of probation since one of the requirements is to refrain from breaking the law. At this point, you should definitely sit down with a local criminal
defense attorney as soon as possible. Until you have an attorney you should not make any statements to anybody,
whether the police or anyone else other than your attorney, about the facts of this case. It is up to the State to prove each and every element of the charges and you don't want to help them do that. So, if you are arrested or asked for an interview, you should invoke your right to remain silent and speak to an attorney as soon as possible.
Please let me know if you have any specific follow up questions. I would be glad to assist you further if I can.
