According to the generally accepted version, Catherine moved to the royal palace with her sisters, but there is an assumption that Catherine and her younger sister Bridget stayed with their mother after leaving the sanctuary. Two years later, in August 1485, Richard III died at the Battle of Bosworth and Henry Tudor became the new king by right of conquest under the name of Henry VII. He fulfilled his promise and married Elizabeth of York, and also canceled the Titulus Regius act, which deprived the children of Edward IV of titles and rights to the throne. The act of Titulus Regius was removed from the archives, as were all documents related to it.

First of all, he wanted to establish peace with his northern neighbour –the Kingdom of Scotland. In November 1487, a preliminary agreement was concluded on the marriage of Catherine with the second son of King James III, James, Duke of Ross, who was almost three years older than the princess. According to the same agreement, Catherine's sister Cecily was to become the wife of the heir to the Scottish throne, James, Duke of Rothesay, and James III, widowed by that time, was to marry the mother of the princess, Dowager Queen Elizabeth Woodville.
