The Braveheart star struck a plea deal with Los Angeles prosecutors in March (11) in a bid to stay out of jail after he was accused of attacking ex-girlfriend Oksana Grigorieva during a heated argument last year (10).
Under the terms of the agreement, Gibson pleaded no contest to simple misdemeanour battery and was sentenced to three years probation, ordered to undergo 52 weeks of counselling, pay almost $600 (£400) in fines and serve 16 hours of community service.
The actor fulfilled his community service sentence on Wednesday (08Jun11) after flying to Guatemala to work with a local team from Mending Kids International, the organisation which, until recently, boasted his ex-wife Robyn as President of the Board of Directors.
Gibson's lawyer presented proof of the star's completed tasks to Los Angeles court Judge Stephanie Sautner on Thursday (09Jun11), and stated his client had also settled his fines.
According to TMZ.com, Gibson's psychiatrist gave a glowing review of the star's behaviour in his documents, claiming he's making good progress in his weekly sessions.
