The Goodwin Games - from Carter Bays, Craig Thomas and Mother scribe Chris Harris - will follow three estranged siblings who must reconnect to inherit their late father's fortune.
The project, which will star Ugly Betty actress Becki Newton, has now been ordered to pilot by Fox, according to TVLine.
Newton previously starred in NBC's short-lived romantic comedy series Love Bites.
The actress has also appeared on How I Met Your Mother as a love interest for Barney (Neil Patrick Harris).
The Goodwin Games sparked interest from several networks last year before landing at Fox. Bays and Thomas have also written for American Dad! and The Late Show with David Letterman.
Other comedy pilots picked up by Fox for the 2012-13 television season include John Stamos sitcom Little Brother and Prodigy Bully from Glee star Mike O'Malley.
