Big money, big ego, big bills: how to get divorced Silicon Valley style

Divorce is always hard, but it can be particularly messy in a land of huge wealth, alpha personalities and hard-nosed lawyers who don't come cheap

The billionaire founder of Zynga, the San Francisco-based company that makes FarmVille, has found himself in (very messy) DivorceVille.

Mark Pincus, an early investor in Facebook and Twitter who is worth $1.28bn, separated from his wife, Alison Gelb Pincus, the co-founder of home decor business One Kings Lane. The couple married in 2008, a year after Mark founded Zynga, which grew into a $1bn company within four years. There was a prenup, but in filing for divorce Alison has asked the court to nullify the agreement since Mark's net worth soared during their marriage.
