Lindsay Lohan 'to remain on the premises' at Betty Ford for the duration of her 90-day sentence
In a letter to Lohan's attorney and the Los Angeles Superior Court, the facility writes, "It is understood by the Betty Ford Center that your client is to remain on the premises for the duration of her 90-day stay in treatment."
Lohan isn't physically locked-up, however, so technically the center cannot stop her from running away. But she will be closely monitored while she is there.
The letter goes on to detail Lohan's treatment, which will include a physician, nurse, case manager, spiritual care counselor, family counselor, psychologist, dietician, fitness trainer and a chemical dependency technician.
"There is physical exercise and group therapy every day. This is not a vacation," an intake counselor tells People.
