Let’s say you’ve already signed, sealed, and delivered that prenup, gotten married, and gone to Mexico for your honeymoon. It’s now been a few years of marriage, and you bought a new house. Do you need to go back and add this new home to your prenuptial agreement's financial schedule or terms? Not necessarily! You should have clauses in your prenup that “cover” you in all situations, including the situation of acquiring new assets during the marriage that didn’t exist when you signed the prenup. Let’s dive into this question and explore some more.
Before we dive into adding property to a prenup after marriage, let's get a good grasp on what prenups are all about. So, a prenuptial agreement is a contract that spells out the nitty-gritty details of how assets, debts, and financial responsibilities will be managed during divorce and how they will be divided in a divorce. It's like a roadmap that brings clarity and protection to both partners, making sure things get split fairly and avoiding unnecessary drama during a divorce. Prenups are also an emotional document that can help bring a couple closer together (and 83% of HelloPrenup customers agree that the process made them feel closer than ever).
Typically, prenuptial agreements are drafted and signed before the marriage ceremony takes place. They specifically outline in the financial disclosure the assets and debts the couple brings into the marriage. The process of financial disclosure is when both spouses share the values of their assets, debts, and even future inheritances with one another by documenting them in a financial schedule and attaching it to the prenup agreement. These values are calculated as of the date of the prenup signing. In addition, the clauses in the agreement may specifically refer to specific properties listed in the financial schedule (a.k.a., assets owned prior to marriage).
So, do you need to go back and amend your prenup every time you purchase a new property? Probably not because it's likely that a well-drafted prenup already covers any future acquired property. That’s right, your prenup (if done well) should already account for any of the stuff that you don’t have yet. Yes, it also covers your existing property, as well. How does that work? Well, you add in clauses for specific situations: appreciation, exchange of property, purchasing new property, future income, future businesses, and future inheritances. All of these things should be expansive enough to cover every single future purchase you make.
You might be wondering how a prenup can possibly account for all of your future assets. It is possible! We always say that a well-drafted prenup never has to be amended. Here are some ways a prenup can account for future purchases:
As you can see, you can get pretty granular with all of the potential future acquisitions of assets, and well-drafted prenuptial agreements will typically take these into account.
"Financial disclosure" is the part of the prenup-making process that requires both spouses to share financial information with each other. This includes assets, debts, and future inheritances. If anyone skimps on this, it puts the entire prenup at risk of being thrown out, so both parties must be adding everything, yes, everything. For example, if you own a home and a bank account, you would need to include detailed information about both, including the values of each as of the date of the prenup creation. Thus, all your financial information is recorded as of the prenup date. However, what happens if you purchase new property after the date of the agreement? Do you need to amend the contract's financial schedule each time you buy new property? Not necessarily. If there is a significant change in wealth or acquisition, then you may want to consider an amendment or ratification of the agreement just to be safe, but it's not typically required.
While it’s not always necessary to add property to a prenup after you’ve already been married, if you’ve created an all-encompassing prenup, some people may still want to do so or be advised by an attorney to do so. If that’s you, and you’re looking to modify or amend your prenup based on new assets you’ve acquired, then listen up. For starters, amending a prenup requires the agreement of both spouses. If your spouse doesn’t want to update the prenup, then you can’t update it. It’s a contract, so it works two ways. Secondly, you must adhere to the legal requirements of the state that governs your prenup. This may mean getting the amendment witnessed, notarized, or obtaining legal representation (or other requirements).

In conclusion, while prenuptial agreements are typically created before marriage, it is possible to add property to a prenuptial agreement after tying the knot. But is it necessary? Not usually. If you have a well-crafted prenup, you should not have to worry about adding property to a prenup after marriage because your prenup will already cover future purchased assets. If you still want to add property to a prenup, for whatever reason (personal preference or from the advice of an attorney), make sure you follow your state’s requirements for amendments or postnups and speak with a local prenup lawyer.
