A progress report hearing lasted less than 10 minutes on Wednesday after the actress successfully completed the benchmarks set by Superior Court Judge Stephanie Sautner.
Lohan has worked at the morgue for 12 days since her sentencing Nov. 2 and completed five therapy sessions.
Sautner gave Lohan an incentive to work harder, telling the actress she could leave California for personal visits once she completes 12 days of morgue duty a month.
Lohan returned from a trip to celebrate her sister's birthday in Hawaii hours before her court appearance.
Lohan remains on probation for a 2007 drunken driving and a grand theft case filed earlier this year.
