Gavin Rossdale and Gwen Stefani did not have a pre-nuptial agreement, a source close to Rossdale tells ET.

The same source says that the 50-year-old Bush frontman is not pushing to get a 50 percent stake in all the money Stefani, 46, earned and assets she accumulated during their nearly 13-year marriage, despite the fact that he's entitled to under California law. Rossdale has a reported net worth of $35 million; Stefani is reportedly worth $120 million.

What the estranged couple will be sharing is custody of their three children: Kingston, 9, Zuma, 7, and Apollo, 2. Rossdale agreed to 50-50 joint custody of the kids and did not ask for child support.

The divorce settlement is still pending a judge's approval, but once it's finalized, Stefani would be free to walk down the aisle again, which could be good news for her boyfriend and The Voice co-star, Blake Shelton.
