I write celebrity prenups. Here are some surprising rules you might find in these marriage agreements.

"When a celebrity relationship turns into a love story, they often have a member of their team reach out to me or a lawyer like me. Usually, it's a business manager or wealth manager who has been tasked with making sure their client protects their reputation and net worth with a prenuptial agreement. The discussion about prenups happens well before there's even a ring."

"It's typical for prenups to detail what each partner can (and can't) post on social media. No one wants their spouse venting about them or their company online, even after the marriage ends. Oftentimes, prenups have confidentiality and nondisclosure clauses, which prevent a partner from penning a tell-all memoir or even a disparaging Instagram post. They outline lifestyle expectations during the marriage Prenups aren't just about what happens if a marriage fails."

Celebrity and high-net-worth individuals typically initiate prenup negotiations through advisors such as business or wealth managers. Negotiations begin well before engagement and can take months to finalize. Complex prenups can extend to 100 pages or more. Provisions often restrict what spouses can post on social media and include confidentiality and nondisclosure clauses to prevent tell-alls or disparaging posts. Prenups also set lifestyle expectations during marriage, including discretionary spending limits and provisions for cars or other benefits. The agreements protect reputation, preserve net worth, and formalize financial and behavioral expectations between partners.
