A court in Paris, which last week found Ian Bailey guilty of the murder of Sophie Toscan du Plantier, has ordered him to pay €115,000 to reimburse the French agency that compensated her family for her loss.
Mr Bailey was tried and convicted in his absence at the Cour d'Assises in Paris last week.
He was sentenced to 25 years in prison and a warrant for his extradition is expected to be processed in the coming weeks.
Mr Bailey has denied involvement in the 1996 murder of the French film producer at her holiday home at Toormore in west Cork.
He refused to present himself to the court in Paris. His lawyer Frank Buttimer dismissed the proceedings as a show trial.
Ms Toscan du Plantier's family used a provision in French law to sue the state there for compensation for her loss.
The agency, known as the Fonds de Garantie, pays compensation to victims of crime or terrorism.
The family succeeded in its proceedings against the agency and, in March 2013, the High Court in Paris confirmed the terms of a settlement order between the parties.
Under the terms of the settlement, the agency paid Ms Toscan du Plantier' parents, Georges and Marguerite Bouniol, €25,000 each.
Her son, Peirre-Louis Baudey-Vignaud, received €30,000. Her two brothers, Bertrand and Stéphane Bouniol, received €15,000 each, and her uncle, Jean-Pierre Gazeau, €5,000.
In a judgement issued yesterday, presiding judge Frédérique Aline, ordered Mr Bailey to pay the Fonds de Garantie €115,000 to reimburse the agency for its outlay.
The court also cleared the way for Ms Toscan du Plantier's aunt, Marie-Madeleine Opalka, to claim €10,000 from the agency.
Alain Spilliaert, a lawyer for the Bouniol family, welcomed the judgment and the guilty verdict against Mr Bailey.
Speaking to RTÉ News from Paris, Mr Spilliaert said he hoped these would be "the first step" towards another trial of Mr Bailey in his presence in France.
