Kevin Federline's attorney, Mark Kaplan, gives a glimpse of the much-talked about deposition that took place without giving anything away. The lawyer has told People magazine about the difficulty experience that happened behind closed doors and what he thinks of Britney Spears finally showing up and staying through the ordeal.

"We are going over things that are very, very gut-wrenching," Kaplan says. "Just to revisit them in your own mind would not be pleasurable."

"It's not something anyone would enjoy."

Spears has had missed numerous appointments and had recently appeared for only 14 minutes on the January 3 meeting. She was expected to be grilled about her ability to be a capable parent in her bid to regain custody of her two boys, Sean Preston, 2, and Jayden James, 1. Federline was granted sole legal and physical custody of the children following a meltdown and brief hospitalization.

"She was about 50 minutes late," Kaplan says of Britney on Monday's session. "After an hour I would have been over it. I was prepared to terminate had she not showed at that time."

Kaplan reveals that this is not the last of the deposition n meetings. "There is a lot of work to be done. He says that he has only worked through 2 percent of his questions."

"She came for her deposition, that's great. Showing up is a form over substance."
