When it comes to finances, both stars had made most of their money before they got together, with Jennifer's hefty pay day from Friends and Justin's work on Tropic Thunder secured and not up for grabs during any potential settlement deals.
But division of assets may not even be an issue - after it emerged there was 'no evidence' the two ever officially married according to DailyMail.
The former couple revealed last week that they decided to go their separate ways at the end of 2017, two and a half years after they tied the knot at Jen's Bel Air home.
But it has since emerged that there is no evidence a legal ceremony ever took place.
TMZ checked records in Los Angeles county as far back as 2010 and found no record of their marriage licence. The pair did not opt for a confidential marriage licence.
While it is possible that Jennifer, 49 and Justin, 46, filed their paperwork in a different county in Los Angeles, sources close to the pair insist this is not the case.
The pair announced their 'separation' earlier this week, in a joint statement.
They said: 'In an effort to reduce any further speculation, we have decided to announce our separation. This decision was mutual and lovingly made at the end of last year.
We are two best friends who have decided to part ways as a couple, but look forward to continuing our cherished friendship.'
