Lunden Roberts, the child's mom, accused him of mischaracterizing his wealth in a child support suit.
A judge has ordered Biden to appear in court next month to answer Roberts' questions.
Although he initially denied paternity, Biden said he has since paid Robert's more than $750,000 in support payments for her.
Biden has asked a judge to reduce his $20,000-a-month child support payments, and not grant Robert's petition to change their daughter's last name to Biden.
Neither Biden's lawyer, Abbe Lowell, nor Lancaster, Roberts' lawyer, returned Insider's requests for comment on Wednesday.
