Barack and Michelle Obama’s possible divorce might have serious financial and legal repercussions.

Their $70 million empire has been built through their joint ventures, which include best-selling memoirs like Becoming and A Promised Land, as well as their production company, Higher Ground, which has a multimillion-dollar deal with Netflix.

Their $11.75 million Martha’s Vineyard estate and their $8.1 million Washington, D.C. home could be divided in a tense way if there is no prenuptial agreement.

If negotiations go awry, experts estimate that legal fees alone could amount to millions.

The financial stakes of any possible split are still unquestionably high, even though neither Obama has publicly responded to the rumors.
