Prenuptial agreements, better known as prenups, have historically gotten a bad rap.

Getting married is one of the biggest financial decisions you’ll ever make, notes Sarah Luetto, a partner at the law firm Blank Rome who specializes in matrimonial and family law. “We like to think of prenups as being more akin to a partnership agreement,” she said. You wouldn’t go into business with someone without thinking about the economic terms of this arrangement, deciding the division of certain expenses and labor, and how you’re going to share profits, she explained. A strong prenup creates a similar roadmap with your life partner.

Pets: Luetto is seeing more 30-something couples including pets in their prenups. Just keep in mind that the treatment and enforcement of these agreements varies by state. She says clients use prenups to clarify if they had the pet before marriage, whose pet it is, and what the expectations are if the couple splits or someone dies. This can include custody and visitation, as well as sharing expenses like vet costs, food and treats.

Embryos: “A legal issue that is coming up more and more, especially with younger people who work for tech companies with fertility benefits, is what to do with shared embryos,” Luetto says. “The battle over embryos is becoming a big problem in divorces now.” Not to mention an emotionally and financially fraught one. So unmarried couples with shared embryos may want to modify the terms of the contract signed with the fertility clinic as part of a prenup process.
