Vanessa Trump is seeking an uncontested divorce from Donald J. Trump Jr., president's son, according to a public court record filed Thursday. Details of the divorce complaint haven't been made public.
The couple, both 40, married in 2005 and have five children.
The Trump Organization, where Trump Jr. is an executive, didn't immediately respond to an emailed request for comment. The court filing didn't include the names of the couple's lawyers.
Vanessa Trump's engagement and marriage to Donald Trump Jr. had been a subject of tabloid fascination in New York long before her father-in-law, Donald Trump, entered politics.
At the time of their engagement, there were unflattering stories about how Trump Jr. had accepted a free diamond ring from a jewelry merchant in New Jersey in exchange for staging a re-creation of his wedding proposal outside the store for reporters and TV cameras.
Last month, Vanessa Trump opened a letter to her husband containing an unidentified white powder and was briefly hospitalized as a precaution, but the substance turned out to be nonhazardous.
A Massachusetts man later was charged with sending the threatening letter.
