Marriage is a balancing act and, at times, a precarious one. Love, logistics, life’s never-ending surprises… It’s rarely ever like it’s portrayed in the movies (or even on Instagram). The causes of this marital stress vary from each couple and at different parts of your lives, but there are some common trends, mainly centering around finances. So, why wouldn’t we take any chance we have to ease some of that tension? Enter: The postnuptial agreement, a.k.a. the “postnup,” which can help put some of those financial worries to bed. Let’s dive into how postnups can actually reduce some of that marital stress.
Trends in marital stress
Marital stress isn’t a new phenomenon. It’s been around for as long as marriage has. But stressors have shifted in today’s world. What are some of the common stressors of today’s day and age? They can include:
- Dual-career households
- Student loan debts
- Digital distractions
- Trying to find work-life balance
- Childcare
- Work-related tasks
- Traffic/long commutes
- Caring for aging parents (and often caring for children at the same time)
These daily stressors can impact the marriage because they directly stress the couple as a whole, or daily stressors of one person can “spill over” to tank a marriage’s health. And (go figure) research has also shown that when both partners are facing higher levels of daily stress, they also report higher levels of marital conflict.
Something that hasn’t changed with time? Money remains the top source of conflict in relationships. What can significantly reduce this stress? Open communication and clear agreements.
What’s a postnup actually is
A postnuptial agreement is very similar to a prenuptial agreement; both are contracts that clarify how assets, debts, and financial responsibilities are handled between a married couple. Yes, that includes if the marriage were to end, but it doesn’t mean creating one (prenup or postnup) is the same as planning for divorce.
The key difference is that a postnup is hammered out after you say, “I do.” Couples do this after the wedding for lots of different reasons. It could be something as mundane as a change in family obligations to something as intense as reconciling after infidelity. Other reasons for getting a postnup can include changed financial circumstances, inheritance, or debt management.
So, how does a postnup decrease marital stress?
What is the top source of marital distress and conflict? Money. So how can a postnup help with this? Here are some ways a postnup can reduce money-related marital stressors:
Clarity (and kindness) around finances
Not knowing who is responsible for what can cause small fights to snowball into resentment or significant fights. A postnup creates an opportunity to make a game plan together, reducing the “Wait, I thought you were going to take care of that!” arguments and ensuring you’re both on the same page.
Creating space for communication
Drafting up a postnup will require honest (and sometimes awkward) conversations about money, goals (as a couple and as an individual), and fears. Can you avoid these conversations and still complete a postnup? Of course. But why start this process and not get the full benefit? It’s like cleaning out the junk closet or the garage—it’ll get a bit messier when you first start, but you’ll feel lighter and accomplished when you’re done.
Financial protection for both partners
Nobody likes to think about “what if,” but having a safety net can allow you both to have the peace of mind that if anything were to happen you have protected each other in a collaborative way. A postnup also means that both partners are on the same page and understand clearly what divorce will mean for you each financially.
Creates a roadmap for life changes
Life throws curveballs—new jobs, aging parents, children. A postnup can be updated to reflect those shifts and build in structure to have these conversations to keep your marriage aligned. Nothing stays the same forever, but you can future-proof your marriage and decrease the stress these life changes can bring.
Promote financial fairness
Sometimes, one partner handles all the finances while the other (intentionally or not) stays in the dark. This can be stressful for both sides. One person is left holding all the responsibility and stress, and/or the other feels helpless and untethered with no sense of autonomy. A postnup brings transparency, ensuring that both partners know what’s happening and agree to the financial decisions and roles.
Financial disclosure
Postnups require something known as financial disclosure. This is the legal requirement to share the value of each person’s full income, assets, debts, and future inheritance. This creates an unmatched level of transparency between a married couple that can help fizzle out certain financial question marks and hopefully prevent certain conflicts.
Is the awkwardness of a postnup talk worth it?
Yes, the first (and maybe second and third) conversation can be awkward. But so can arguing about money or silently resenting your partner over financial omissions. Keep your goal in mind, approach the conversation with empathy, and frame it as a tool to decrease marital stress and strengthen your marriage. Kick things off with something like, “I want us to use this to make sure we’re on the same page.”
How to get the convo started:
- Timing and tone matter. Choose a calm moment and make sure each person feels prepared to start the conversation.
- Bring in experts to support you. These can be attorneys, mediators, financial advisors, or couples’ therapists.
- Be honest and clear. This is a chance to lay everything on the table—the good, bad, and complicated. Don’t kick the proverbial can down the road by only sharing 60% of what’s on your mind. Honor your commitment to each other and be fully honest with each other.
- Focus on collaboration. Be prepared. You’re not going to agree with everything you both have to say. And that’s okay. This is meant to be a time to discuss, collaborate, negotiate, and make concessions. The process is just as important as the result.
Final thoughts on how postnups can reduce marital stress
Marriage is a partnership, and like any partnership, unclear expectations can breed distress and resentment. Clear agreements (about any part of a marriage) can help prevent misunderstandings and set up a way to have hard conversations. A postnup isn’t a red flag for trouble. In fact, it can be a tool for the forward-thinking couple that is looking for clarity, fairness, and peace of mind. Life is complicated enough without adding more (avoidable) stress! So, while you may not need to be on a literal tightrope or swing through the air, having a postnup can be your marriage safety net.
