(CNN) Indicted Rudy Giuliani associate Lev Parnas said in a new court filing Monday that he would take the Fifth Amendment during a December hearing and decline to answer certain questions about his campaign donations.

Parnas is set to testify in a federal court in Florida on December 13 about his previous campaign finance payments during a hearing that could last up to three hours, according to a new order setting his deposition.

The hearing, part of a civil proceeding after Parnas failed to pay back an investor, is slated to involve questioning about a loan he took years ago and hasn't repaid. He owes a family trust more than $500,000, and the trust has gone to court to enforce the payment.

In that pursuit, the family trust has collected information about Parnas' more recent financial dealings, including what they allege to be money he fraudulently transferred to his corporate accounts, to the Trump PAC America First Action, to the National Republican Congressional Committee and to Pete Sessions for Congress, according to the court filings.
