Same thing happened to me
So the wife and I were getting a divorce. No big deal, except we had this damn house. The wife said it was worth £100K, but our lady realtor said we should sell it for less than £80K. My wife didn't believe it, so she sued me for selling it under market price because I was having an affair with the same lady realtor/appraiser that I sold it to for £75k. "One opinion against two," I na-na-na-na-na-nad. "Tough luck."
Unfortunately, the judge agreed with my ex and said I owed her £12.5k plus interest. Luckily, the judge also said I didn't have to pay any penalty or worry about being prosecuted for theft or breech or anything since I made sure everybody knew I was having an affair with the realtor lady. I have no idea where my barrister dug up that goofy precedent or earned some ancient favour he could call in, but it didn't come cheap.
Then again, I didn't spend anywhere as much time in bed with my wife and mistress combined as Dell spent in bed with Silver Lake, so it's not exactly the same thing. I.e., Dell get off lucky.
