LOS ANGELES (CNN) — Lindsay Lohan is again close to being thrown in jail for not doing what a judge ordered.
The actress is in danger of missing Thursday's deadline to check into a court-approved rehab program, according to her father.
Lohan boarded a flight from New York to Los Angeles late Wednesday hoping to sort out what facility she will spend 90 days of treatment.
A judge ordered the treatment after Lohan entered pleas of no contest on charges relating to a traffic accident and she was found in violation of her shoplifting probation with those convictions, Michael Lohan told CNN.
"It's not her fault," her father said. "This poor kid was a mess before she left."
Her lawyer, Mark Heller, arranged for Lohan to check into Morningside Recovery in Newport Beach, California, but prosecutors have not approved that facility, he said.
"Lindsay had no idea that Morningside wasn't approved," Michael Lohan said.
Heller will be in a Los Angeles court to discuss the matter with the judge and prosecutors Thursday morning.
Her father, who has bitterly opposed Heller's representation of Lohan, said he has been urging his daughter to go the the Lukens Institute in Palm Beach Gardens, Florida, which bills itself as a "luxury rehab center."
"The Lukens Institute is where she wanted to go all along -- a place she will get the right treatment and finally get better," Michael Lohan said.
Although Lohan was sentenced to jail time, including five days and 90 days on two charges, the judge will allow her to serve it in rehab. The sentence extends Lohan's probation for two years and requires 18 months of psychotherapy.
"This is it," Dabney told her. "You violate your probation, and we're not going to have discussions of putting you back on probation."
Her six years of legal troubles trace back to two drunken driving arrests in 2007 and include other incidents in which she was behind the wheel.
Lohan was charged with reckless driving and lying to a police officer about a June 2012 car crash in which her Porsche crashed in to a dump truck on the Pacific Coast Highway in Santa Monica, California. Her arrest triggered the probation violation charge.
The police report said Lohan denied being behind the wheel, but the prosecutor was expected to call witnesses who say she was driving.
Lindsay Lohan acknowledged her drug and alcohol addiction in past court appearances.
She's spent 250 days in five rehab facilities since January 2007, including one long court-ordered stint after a failed drug test.
The actress has appeared in court at least 20 times before four Los Angeles judges who have now found her in violation of probation six times and sentenced her to a total of nine months in jail.
Lohan has spent about two weeks behind bars in six trips to the Los Angeles County jail, served 35 days under house arrest and worked about 67 days of community service at the county morgue.
