Sebastián Rulli and Cecilia Galliano have been battling in court over a truck she gave to him when they were married, and their lives may soon get even more complicated.

According to TV Notas, Rulli doesn't want to just win the current court case—he also wants to take their son, Santiago, away from her. At the beginning of the year, both went to his school to celebrate his birthday with him. TV Notas reports that documents exist that back up the claim that he wants sole custody. 

TV Notas spoke to an inside source who provided details of what actually happened inside the ex-couple's court case.

The source said, "Finally, Sebastián Rulli's expert came, who had a threat of a $10,000 fine if he didn't show up. There were interviews with the three experts together with the two parties, who are asking questions that everyone must answer..."

The source didn't seem to be a big fan of Rulli, calling his and his lawyer's attitude ridiculous and arrogant. He rejected many of the questions that were asked. The source also questioned the expert that Rulli chose.

"Her expert has 45 years of experience, and he has served on more than 1 million cases. He seems capable. And Mr. Paz Miranda can't remember how many surveys he has made in his just five-year career. And he's made errors," the source said.

He said the environment was tense, and that Rulli's lawyer ended up yelling at Galliano in front of everyone.
