Las Vegas authorities announced last month, that there was not enough evidence to bring criminal charges against the footballer.
Mayorga is pressing ahead with a civil case, but Ronaldo’s lawyers want to have it thrown out.
According to them, the claim was already settled with a payoff and confidentiality agreement in 2010.
In newly filed court documents, Ronaldo’s camp are said to acknowledge the $375,000 figure. They insist the payment was not an admission of guilt, but merely an effort to keep the story from public attention.
Mayorga’s lawyers now want the agreement thrown out.
