The documents, signed in 2010, reveal details of the £287,000 agreement which required the woman to remain silent about her claims.
Kathryn Mayorga, a 34-year-old teacher, says the ex-Manchester United forward s*xually assaulted her at the Palms Casino Resort in June 2009, while he celebrated his big money move to Real Madrid.
According to the documents published in Der Spiegel, the football star’s accuser Ms Mayorga was to be paid the money within seven days.
The documents contain a clause stating that should she test positive for a STD, Ronaldo would have to undergo a test for that particular disease – presumably in order to exclude or confirm him as the source.
It also published what it claimed was a copy of the police report filed just hours after the alleged rape.
This describes her as crying and refusing to give the name of her alleged attacker, saying only he was a “public figure” and an “athlete”.
Ronaldo denies all the accusations of s*xual misconduct and has been backed by his new club Juventus.
But she now claims she only signed because she was terrified of “retaliation” and “public humiliation” and her lawyers are now suing Ronaldo.
Las Vegas Metropolitan Police Department has also re-opened its investigation into the alleged rape.
