The Texas teenager who used an "affluenza" defence over the deaths of four people in a drunken-driving crash may have his case moved to the adult system.
Ethan Couch, 18, is due in court on Friday in Fort Worth.
He could face up to 120 days in jail as part of the terms of adult probation.
A ruling keeping him in the juvenile system could trigger hearings in which Couch could either go free or be sent to prison for 10 years when he turns 19.
Couch's lawyer has said he will not challenge a transfer to adult court.

Authorities say Couch and his mother fled to Mexico in December, as prosecutors investigated whether he violated his probation in the 2013 wreck that killed four people.
Couch was booked in the Tarrant County Jail in February after being deported from Mexico in late January.
