Robert K. Kraft, the owner of the N.F.L.’s New England Patriots, has pleaded not guilty in Florida to charges of soliciting prostitution.

The plea, on two first-degree misdemeanor charges, were submitted in writing to the state attorney’s office in Palm Beach County, not in person. Mr. Kraft requested a nonjury trial. The plea was filed Monday and made public on Thursday.

Mr. Kraft was charged with two first-degree misdemeanor counts of soliciting prostitution. He was one of 25 people charged by the state attorney. If convicted, Mr. Kraft would face up to one year in jail, a $5,000 fine and 100 hours of community service. However, at a news conference on Monday, the state attorney, Dave Aronberg, said that first-time offenders rarely spent time in jail.

Mr. Kraft has a scheduled court date of March 27 in Florida. He is not required to be present and most likely will be represented by his lawyer, Jack Goldberger.
