well in one of the books i think legacy of the jedi someone does get expelled from the order but the council arranges for them to join the agricultural corps of course they refuse. and then before obiwan was a jedi quigon at first didn't want to take him so because he was to old and wasn't chosen by a jedi knight he was sent to Bandomeer to become a farmer but then quigon and him were thorwn together and quigon took him
so what i'm saying is if a jedi decides to leave the jedi order or is forced to the council probably sets them up for another life or they just find their own life away from the jedi
Many things can happen to a Jedi if he/she/it leaves the Jedi order. If he/she/it leaves by their own free will, it is because they have either been tempted by the dark side (Sith, dark Jedi, etc.), or they are on the run because they failed to complete a major assignment (Ex. Darsha from the book Darth Maul: Shadow Hunter). If the Jedi is disbanded by the order, they will either go to the dark side (again, Sith or dark Jedi) or they will accept that their powers have faltered and they will find a new path of life far from the teachings of the Jedi order. hope this helped :)
Well, it depends at what station of life. If they are initiates, or 'younglings' as they are called, they go to serve in the Jedi Service corps. IE, they serve the galaxy by way of the four corp branches: Agriculture (Agri-corps), Medicine (Medi-corps), Education (Edu-corps) or Exploration (Explo-corps). This also applies as a Padawan, and (i think) Jedi Knights. Hope this helped :)
If the Jedi left the Order for what ever reasion, They would probly go back to his/her home planet and find there real family, but if they did not have family alive they would make a home somewhere and make a family or find a job.
On the other hand if the Council kicked some one out of the Order then they would be sent to be a farmer, where they send Younglings if they are not chosen as Padawans.
