A celebrity couple known for making public displays of attention announced that they were separating this week. Musical artist Seal and supermodel Heidi Klum confirmed their separation on Sunday, after almost seven years of marriage.

If the California couple decides to move forward with divorce there will likely be a lot of assets at stake. Not to mention, the couple has three children together and a fourth from Klum's previous relationship, so child custody will also be an issue.

Ultimately, the details of a divorce will depend on whether or not the couple has executed a prenuptial agreement. It there is no prenup, all income that was earned by either party during the marriage will be split 50-50 upon divorce because California is a community property state.

However, E! Online reported that a prenup is likely. A managing partner at a California family law firm told E! that "given the statures of these two people, you have got to believe that their business managers were telling them they have got to have a prenup."

E! reported that a prenup would likely keep all individual business ventures as separate income. Additionally, it could set the terms for spousal support.

According to E!, if any spousal support is granted, it is likely that Klum will be paying Seal as she earns more income. While Seal has sold 20 million albums worldwide, Klum is the second-highest paid model in the world and reportedly made $20 million last year alone.

Of course, it is certainly possible that the couple will settle their divorce confidentially out of court, which means that the terms of the property settlement may never be released to the public.
