Long-suffering Stacey, 38, who dumped the Manchester United star a year ago after he was linked to a PR executive, looked impassive in sunglasses and a black outfit for the showdown.
Mr Justice Cobb is overseeing the latest stage of the dispute at a private hearing in the Family Division.
However, the Manchester United hero was regularly seen wearing his ring with pals claiming he was desperate to give their relationship another shot.
Giggs, 43, who has built an impressive hotel and restaurant portfolio since hanging up his boots two years ago, is still living with Stacey and their children Libby, 13, and Zach, ten, while he looks for a new home to live in.
A source said: “After years of being made to look a fool in public as a result of Ryan’s cheating, Stacey will finally break free.
“It’s only fair she gets what’s hers from their marriage.
“She deserves every penny for the humiliation Ryan put her through after cheating on her with his brother’s wife, and the regular rumours he was still being unfaithful.
“It’s going to be extremely painful for Ryan as he’s carved out a very successful hospitality business since retiring from playing football.”
