Lindsay Lohan is trying to shorten the terms of her probation.
The troubled star's legal team want the length of the court-ordered terms - which are presently scheduled to run until August 2011 - lessened, as they fear she will "get in trouble" before the period ends.
Lindsay is presently in the Betty Ford rehab centre in Los Angeles, following two spells in prison this summer; serving 13 days of a 90-day jail term in July before briefly being returned in September after failing drug tests, although she was released hours later on $300,000 bail.
A source explained to RadarOnline.com: "The longer Lindsay stays on probation, the increased chances that she will get in trouble because of problems staying compliant with the terms of her probation.
"The only person that can modify terms of Lindsay's probation, or terminate it early, is Judge Elden Fox."
'Machete' actress Lindsay could again face a return to prison, as she is due in court on October 22 for a probation hearing, after her failed drug tests, which could see her incarcerated again for violating the terms of her probation for a 2007 driving under the influence (DUI) conviction.
Friends of the star have said she isn't worried by this prospect, however, and is prepared to return to jail.
One pal said: "The fact is jail doesn't scare Lindsay. Before she did her time earlier this summer, she was petrified. Having spent time behind bars, it doesn't have that effect on her. Jail isn't a deterrent for her, period."
