Ah, prenups: the contracts that soon-to-be married couples sign in an admission that "til death do us part" actually means "until I just can't handle you snoring anymore". Relationships have had to catch up with the digital revolution and now prenups are too – with a social media clause that forbids posting about your recently divorced partner on social media. 

"When they have this social media clause, each party will agree not to post, tweet, or otherwise share via social media, positive, negative, insulting, embarrassing, or flattering images or content of the other," said New York-based attorney Ann-Margaret Carrozza, speaking to Fox.

It's possible to customise the clause but Carrozza says that it's wisest to put an embargo on all kinds of posts on social media, irrespective of whether or not you consider the post to be "good" or "bad". That means that even if you wanted to relive the glory days and post a picture of your ex in happier times, you can't. To be honest, that's kind of creepy anyway.

Prenups came into fashion at the turn of the millenium when Michael Douglas and Catherine Zeta-Jones tied the knot, but Edward IV reportedly had a pre-nuptial agreement with Eleanor Butler time (although 15th century prenups presumably had no Twitter clauses). But if you're walking down the aisle with somebody you suspect might shame you on social media, maybe it's doomed to fail from the start?
