The 'Constant Craving' singer filed paperwork in January to officially split from Price after nearly a decade together.
A judge has now formally dissolved the legal partnership after both sides agreed to an even distribution of assets.
Neither Price nor Lang is seeking any form of spousal support, according to TMZ.
The couple apparently met in 2003 through a Buddhism teacher.
Lang released her most recent studio album Sing It Loud in April 2011 in the US.
