The Salt Lake Tribune reports Judge James Taylor ruled Monday that Coleman and Shannon Price didn't have a common-law marriage, despite living together after they divorced.
Coleman died of a brain hemorrhage in 2010. Taylor is deciding whether Price or Coleman's ex-girlfriend Anna Gray is entitled to his estate.
The judge says Price moved out of Coleman's home multiple times after their 2008 divorce and the couple didn't give a public impression of marriage.
Price has said she and Coleman "couldn't be without each other," even after their divorce. Gray managed Coleman's affair for years and says Coleman named her a beneficiary and executor of his estate in 2005.
At stake is a house worth more than $300,000, intellectual rights to some of Coleman's works and the "Diff'rent Strokes" star's ashes.
