Lohan was scheduled to appear Monday at New York criminal court to learn whether a prosecutor plans to pursue a case against her for her alleged role in a fight at a Manhattan nightclub -- but her court appearance was delayed.
Lohan's attorney says the court day may never happen.
"It has been determined that the criminal prosecution of Lindsay Lohan is not ready to proceed at this time," Lohan's attorney Mark Heller said.
Lohan was charged with misdemeanor assault after allegedly punching a woman in the early morning hours of November 29, 2012.
She is accused of hitting Tiffany Mitchell, 28, of Palm Beach, Florida, at the trendy Avenue Lounge in Manhattan's Chelsea district.
It is the latest legal trouble for the 26-year-old actress, whose struggle with drugs and alcohol has seen her bounce in and out of court 19 times and to five rehabilitation facilities since 2007.
Lohan's New York lawyer, Mark Heller, told CNN in November: "Once again, Lindsay Lohan is a victim of someone trying to capture their 15 minutes of fame."
"From my initial investigation, I am completely confident that this case will be concluded favorably and that Lindsay will be totally exonerated," Heller said of the New York incident.
The New York case comes a little more than a week before the actress is scheduled to appear at a probation violation hearing on January 15 in California.
Lohan was on probation for a 2011 conviction on charges she stole a necklace, but that probation was jeopardized in November 2012 when the city attorney in Santa Monica, California, filed four charges against her in connection with a car crash last summer.
In the Santa Monica case, Lohan is accused of giving false information to a police officer, obstructing or resisting a police officer in performance of his duty, and reckless driving, according to the city attorney's office.
The charges, all misdemeanors, stem from a car crash while Lohan was on her way to the set for the filming of "Liz & Dick," a Lifetime movie that aired last year.
