Tiger Woods could be forced to hand over an estimated £100m to Elin Nordegren after the pair finalised their divorce.
"The rumours are bouncing around and the smart thinking is that Elin will receive a settlement into the early £100m, not half of his £1bn," she said.
The pair released a statement on his website saying they were sad their marriage is over and plan to share parenting of their two children - Sam and Charlie.
The divorce confirmation was posted on Woods' website
"Once we came to the decision that our marriage was at an end, the primary focus of our amicable discussions has been to ensure their future well-being.
"The weeks and months ahead will not be easy for them as we adjust to a new family situation, which is why our privacy must be a principal concern."
The hearing took less than 10 minutes and both Woods and Nordegren were present.
The petition said the marriage was "irretrievably broken" and that Woods' wife asked to have her maiden name - Elin Maria Pernilla Nordegren - restored.

There was speculation that the collision with a fire hydrant came after he clashed with Nordegren, a former swimwear model.
Woods was forced to make a carefully-staged televised apology after a string of women - including a porn actress and cocktail waitress - came forward and claimed they had relationships with him.
He has not admitted to specific relationships but said "just one is enough and obviously that wasn't the case".
He denied his wife attacked him on the night of the crash and praised her for showing "enormous grace and poise" as the stories emerged.
Woods, 34, said he "ran straight through the boundaries" that a married couple should observe and convinced himself that "normal rules didn't apply".
He recently returned to golf with limited success and is in danger of losing his status as the best golfer in the world.
