Quote rjames8: Apparantely, the writers forgot that Sharon owned the house. She got it as part of the divorce settlement, Nick gave it to her. I am guessing when she moved in with Jack, the house was available. Victoria just decided she could move in and no one asked Sharon!
Nikki lost the ranch to Victor. She put up her marital assets to secure the NVP loan and lost. The new writers didn't forget anything, they are playing it by the book (legally). There may have been some personal gesture of money that Victor gave Sharon. But legally everything at the Newman ranch belongs to Victor so he can sell the house to whomever he pleases.
Bottom line,the torch has passed. The Newman ranch house is back in Newman hands.
