Who Gets the L.L.C.? Inside a Silicon Valley Billionaire’s Divorce.

A couple are heading to court to decide who is entitled to a fortune, started in the earliest days of Google, that includes valuable California real estate and stock holdings.

PALO ALTO, Calif. — In 2014, Scott Hassan, known by some as the third Google founder, sent Allison Huynh, his wife of 13 years, a text message that their marriage was over and that he was moving out of their home. Nearly seven years later, the pair are still locked in litigation over how to divide an estate with tech investments and prime California properties estimated to be worth billions of dollars. A trial expected to start Monday will offer an unusual, public peek into the details of a big-money Silicon Valley divorce. They include Mr. Hassan’s failed attempt to persuade Ms. Huynh to sign a so-called postnuptial agreement and his admission that he started a website in her name to publicize embarrassing information from her past.
