There's been a 62% spike in people getting prenups, and experts say it's being driven by millennials

Itani explains that another factor leading to an increase in prenuptial agreements among young people is that millennials are getting married later in life than members of past generations.

Unlike baby boomers or Gen X-ers who married in their early twenties, millennials are choosing to wait until their late 20s or early 30s to tie the knot. According to a previous article by Business Insider, in 1962, 90% of 30-year-olds had been married at least once. In 2018, only 54% of 30-year-olds had been married.

"Millennials are waiting a longer time [than past generations] to get married and focusing more and more on their professional careers," Itani explained. "In that sense, they have more assets to protect when they do get married."

Itani explains that while a prenup can certainly help guard and protect the assets couples have going into a marriage, it can also protect assets that individuals might acquire down the line, or secure their financial situation in the case of a future divorce.

"A majority of the prenups that you see are from people who come into the marriage with assets or have assets they expect to receive — whether that be an inheritance from their family or gifts that they want to protect," says Itani.

As much as prenups can be about protecting what you have now, they can also protect what you will have down the line.

"If one client is making a significant income compared to their partner, they may also want a prenup to protect themselves from future support or alimony payments," Itani explains.

Prenuptial agreements have been considered taboo in the past, but millennials are changing that reputation. Prenups were previously seen as only intended for wealthy people, and even had a reputation of leading to divorce — this has been disproven by studies.

"People are becoming more knowledgeable about prenuptial agreements," she says. "Millennials are concentrating more on building their career and becoming more knowledgeable about what assets will come of their career, and what their income will be in the future. Millennials feel it's necessary to protect those assets."

The rise of women in the workforce may also be affecting the rise in prenuptial agreements.

According to a report by The Ladders, women are increasingly becoming interested in signing prenuptial agreements. Pew Research Center reports that 72% of millennial women are employed and, according to a separate AAML study, 45% of attorneys surveyed said more women are responsible for paying alimony after getting a divorce than in previous years.

As more women begin to acquire their own assets and gain financial leverage, there is an increased interest for them to sign a prenuptial agreement prior to getting married.

"Nowadays, with the equalization in the workforce, both spouses are working and becoming professionals," Itani explains. "They both benefit from signing a prenuptial agreement."
