My question involves criminal law for the state of: NY

My son may be getting a YO status for a felony (E). Attorney says it will be a 5 year probation.

What does this mean? How can I get more details on what the probation entails?

What questions should I ask my attorney about this?

What should be expecting....

Please help. I am very clueless on what to expect... or what I need to ask to know....
