In a divorce settlement filed Monday in Los Angeles court it was revealed that Van Der Beek, 33, will pay Heather Ann McComb $7,750 per month until December 2012.
The papers say Van Der Beek's monthly income is $35,000, compared with McComb's income of $1,750 a month.
In the settlement, Van Der Beek will keep their North Hollywood residence, all bank accounts in his name, and all residuals from his acting work and rights to his screenplays and other projects he's created.
The couple, who have no children together, separated last April.
Van Der Beek and McComb got engaged in early 2003 and were married over the Fourth of July weekend that year in Malibu.
The two had exchanged vows in an outdoor ceremony in front of a group of guests that included Van Der Beek's Dawson's Creek costars Michelle Williams, Busy Philipps and pal Soleil Moon Frye.
