Almost two decades later they rekindled their relationship.
“Love is beautiful. Love is kind. And it turns out love is patient. Twenty years patient,” Lopez said in 2022 after announcing the Las Vegas wedding.
The BBC has contacted their representatives for comment.
A court filing in the case says Lopez or her attorney has to notify Affleck with a copy of her petition to dissolve their marriage.
Media reports indicate Lopez, who had legally changed her last name to Affleck, did not list any details of a prenuptial agreement in her petition for divorce.
A document filed in LA's Superior Court in the case says both Lopez, 55, and Affleck, 52, must share financial information, including their current income, expenses, properties and debts.
The document says both are mandated to divulge any changes to their finances "until there is a final agreement all financial issues in your case".
The court gave Lopez 60 days to file a financial disclosure and Affleck will have another 60 days after she submits her information to do likewise.
The filing says if either fails to report or update financial information, it could result in a court-imposed sanction.
There has been months of speculation over their relationship. They reportedly put their Beverly Hills mansion up for sale at $65m (£50m) and were pictured out separately not wearing their wedding rings.
Affleck, a two-time Oscar winner, was previously married to the actress Jennifer Garner, who he met on the set of 2001 romance Pearl Harbor. They split in 2015 after a decade of marriage and have three children together.
Lopez has been married four times, first to Cuban-born waiter Ojani Noa from 1997-98; then her former back-up dancer Cris Judd from 2001-03; and to singer Marc Anthony, with whom she had twins, from 2004-14.
The singer and actress, known as J.Lo, was also once engaged to New York Yankees star Alex Rodriguez.
The Hollywood legend has been racking up acting awards since the 1950s.
Peggy's journey from East Yorkshire to the red carpet has been surreal, says owner Holly Middleton.
