Jamie Spears has asking a judge to force his daughter to sit for a deposition.

Jamie just filed legal docs in which his lawyer says Britney Spears is going on a campaign to trash Jamie in social media and her soon-to-be-published memoir, and apparently Jamie now wants to challenge her allegations.

Among the issues Jamie wants to direct at his daughter under oath allegations that she was forced to give 8 tubes of blood for medical treatment, was forced to participate in therapy and was not allowed to own pain-reliever meds, TMZ says.

Jamie assures that the accusations from his daughter have no basis.
