Ruby Freeman and Shaye Moss, two election workers, were victorious in their lawsuit against Mr. Giuliani last year, winning almost $140 million (£106 million).
Former Trump lawyer Mr. Giuliani had wrongly accused them of manipulating votes in the 2020 presidential election.
The federal judge decided on Tuesday that Mr. Giuliani must give Ms. Freeman and Ms. Moss his watches, furnishings, and sports memorabilia in addition to the flat.
Additionally, the judge decided that Ms. Moss and Ms. Freeman would receive $2 million that the former mayor of New York City claims Trump’s 2020 campaign still owes him.
Last month, Ms. Freeman and Ms. Moss requested that a court take possession of some of Mr. Giuliani’s possessions, including a Mercedes-Benz, numerous luxury timepieces, and other personal belongings, in addition to several properties in Palm Beach, Florida, and New York.
Three of his New York Yankees World Series rings were also highly after, one of which is estimated to be worth $30,000.
The judge ordered Mr. Giuliani to surrender over two dozen watches and a jersey signed by former New York Yankees center fielder Joe Dimaggio in a 24-page ruling that was made public on Tuesday.
