Mel Gibson and Oksana Grigorieva in Court over Lucia

june 14, 2015

Mel Gibson and baby mama Oksana Grigorieva are about to square off in court this morning ... and it's all about their 5-year-old daughter Lucia.

TMZ has learned, Mel is about to go to Australia to do a movie and wants to take his daughter with him for the summer. We're told Oksana objects, so they'll be making their respective cases before the family law judge.

Mel Gibson is extremely involved in Lucia's life. In fact, the judge has continually increased his custody of Lucia over the years, to the point where he now has physical custody of his daughter slightly more than 50% of the time.

Mel walked out of court victorious. The judge is allowing Mel to take Lucia to Australia for 1 month and keep her in L.A. an additional 2 weeks before he leaves the country.

There was a dispute over which kindergarten school Lucia would attend and the judge sided with Mel.
