"We ended up with 119 marriage licenses Monday, and will probably have 150 by the time we close today," said Davis County Clerk/Auditor Steve Rawlings.
Many same-sex couples have come to Farmington since Monday, with some citing long lines in Salt Lake County as their reason for doing so.
"We are being praised on Facebook and on talk radio for the great service we're providing," Rawlings said.
The office will reopen at 8 a.m. Thursday, Dec. 26, after being closed all day Christmas, Dec. 25.
The rush on same-sex marriages came after Robert J. Shelby of the U.S. District Court struck down the Utah's Amendment 3 on Friday afternoon. The summary judgment came after a lawsuit suit was brought against Governor Gary Herbert and the State of Utah.
Amendment 3 defined marriage as a union between one man and one woman, while refusing state recognition of any other union as legal. It was passed into law in 2004.
