You can also click the magnifier at the top of the page and type probation.. you will find lots of results with that word and try to find a situation that looks like yours
Instead of asking questions here to people who dont understand your situation or never had a situation like that and will make you feel more stressed, look for a second lawyer and ask their opinion
