Prenup vs Postnup: What is the Difference?

While prenups and postnups aren’t as romantic as discussing your honeymoon or your dream house, these agreements can be a financial lifesaver if your marriage were to end.

Both prenups and postnups help determine who would get what if you and your spouse got divorced.

These two varieties of agreements carry some significant distinctions. Depending on your circumstances, one may better suit your relationship versus the other.

Here, you’ll learn some of the key ways prenups vs. postnups differ, as well as how to decide if you and your partner would benefit from getting one.

What is a Prenup?

Short for “prenuptial agreement,” a prenup is a legally binding document set up before a couple gets married — hence the “pre” suffix. Prenups may also be known as “antenuptial agreements” or “premarital agreements,” but the bottom line is, they’re contracts drafted before vows are made.

These contracts typically list each party’s assets, including property and wealth, as well as any debts either soon-to-be-spouse might carry.

It then details how these assets will be divided in case the marriage comes to an end, either through a divorce or the death of a spouse.

Who Needs a Prenup?

Couples who are getting married for the first time and are bringing little to no assets into the marriage may not need to bother with drawing up a prenup.

However, a prenup can be particularly useful if one spouse is coming into the marriage with children from a previous partnership, or if one partner has a large inheritance or a significant estate, or is expecting to receive a large inheritance or distribution from a family trust.

These types of agreements aren’t just used in case of divorce, but also death, which can be particularly important for couples with children from a previous marriage.

If that partner dies, the prenup can define how much of their wealth should be passed onto their children versus their surviving spouse.

Prenups can also be useful for protecting assets earned and property acquired during the course of a marriage, which, without a prenup, are generally considered “shared ownership.”

If one partner wants to maintain a separate claim to acquired wealth or possessions, a prenuptial agreement makes that possible.

A prenup can also keep a high-earning partner from being required to pay alimony to their partner in the case of a divorce. However, in some states, a spouse can’t give up the right to alimony, and the waiver may not be enforced by a judge depending on the way the prenup is drafted.

In the event of divorce, a prenup can also help protect a spouse from being liable for any debt, such as student loan payments in a marriage, the other spouse brought into the union.

What is a Postnup?

A postnup, or postnuptial agreement, is almost identical to a prenup — except that it’s drafted after a marriage has been established.

They may not be as well known as prenups, but postnups have grown increasingly common in recent years, with nearly all 50 U.S. states now allowing them.

A postnup may be created soon after the wedding, if the couple meant to do so but simply didn’t get around to it before the big day, or well afterwards, especially if some significant financial change has taken place in the family.

Either way, a postnup, much like a prenup, does the job of outlining exactly how assets will be allocated if the partnership comes to an end.

Who Needs a Postnup?

Along with being drafted whole cloth, a postnup can be used to amend an existing prenuptial agreement if there have been big changes that mean the initial contract is now outdated.

And although it’s not fun to think about, if a couple feels they’ll soon be facing divorce, a postnup can help simplify one important part of the process before the rest of the legal proceedings take place.

A postnup, like a prenup, can help separate out assets that would otherwise be considered shared, “marital property,” which can be important if one partner obtains an inheritance, trust, piece of real estate, or other possession they want to maintain full ownership over.

Postnups can also be part of a renewed effort for a couple to commit to a marriage that may be facing some obstacles and challenges.

Prenup vs. Postnup: Which is Right for Your Relationship?

While it may be a difficult conversation to face with your fiance or spouse, creating a prenup or postnup can be an important step to help you avoid both headache and heartache later on.

If you don’t make a prenup or postnup, your state’s laws determine who owns the assets that you acquire in your marriage, as well as what happens to that property in the event of divorce or death. State law may also determine what happens to some of the assets you owned before marriage.

While almost any couple can benefit from a frank discussion of who gets what in the worst-case scenario, here are the situations in which you might specifically want to consider a prenup vs. postnup.

When to Consider a Prenup

•   If one or both partners have existing children from a previous partnership, to whom they want to lay out specific inheritances in case of death.

•   If one partner has a larger estate or net worth (i.e., if one spouse is significantly wealthier than the other).

•   If one or both partners want to protect earnings made and possessions acquired during the marriage from “shared ownership.”

When to Consider a Postnup

•   If you intended to create a prenup but ran out of time or otherwise didn’t do so before the wedding.

•   If significant financial changes have made it necessary to change an existing prenup or draft a new postnup.

•   If divorce is looking likely or inevitable, and the couple wishes to streamline the process of dividing marital assets before undergoing the rest of the process.

In all cases, prenuptial and postnuptial agreements can help simplify the division of assets in the case of either death or divorce — and in either of those extremely emotionally charged scenarios, every little bit of simplification can help.

However, prenups are sometimes considered more straightforward, since they’re made before assets are combined to become marital property.

Prenups may be more likely to be enforceable than postnups should one partner attempt to dispute it after a divorce.

How to Get a Prenup or Postnup

Here are points to consider:

•   For a prenup or postnup agreement to be considered valid by a judge, it must be clear, legally sound, and fair.

•   Couples looking to save money may be able to use a template to create a prenup or postnup themselves.

•   It may still be a good idea, however, for each partner to at least have separate attorneys review the document before either one signs.

•   If your estate is more complex, you may want to consider hiring an attorney to draft the agreement.

•   Either way, having an attorney review the document will help protect your interests and also help ensure that a judge will deem the agreement is valid.

Reducing the Odds You’ll Ever Need to Use that Prenup or Postnup

While creating a prenup or postnup can be a smart move for even the most hopeful and romantic of couples, the ideal scenario is a happily-ever-after that leaves those contracts to gather dust.

Fighting about money is one of the top causes of strife among couples, and one of the main reasons married couples land in divorce court.

For some couples, one way to improve their odds might be waiting until they’ve achieved some measure of financial stability before tying the knot.

Walking into a marriage with a solid personal foundation, such as a well-stocked emergency fund and a well-established retirement account, can help partners feel empowered and able to focus on other important relationship goals.

Financial transparency, starting before and/or early in marriage, can also help mitigate marital tension over money.

To achieve more transparency, some couples may want to consider opening up a joint bank account, either after they tie the knot or before if they are living together and sharing household expenses.

While there are pros and cons to having a shared account, merging at least some of your money can help make it easier to track spending and stick to a household budget, while also fostering openness and teamwork.

For couples who’d rather not share every penny (or explain every purchase), having two separate accounts along with one joint account can be a good solution that helps keep money from becoming a source of tension in a marriage.

The Takeaway

Prenuptial and postnuptial agreements are both legal documents that address what will happen to marital assets if a married couple divorces or one of them dies.

A prenup is drafted before marriage, while a postnup can be drafted soon after or many years into marriage. Both agreements can make divorce or the death of a partner significantly less traumatic and help divide assets in an equitable way.

SoFi members with direct deposit activity can earn 4.60% annual percentage yield (APY) on savings balances (including Vaults) and 0.50% APY on checking balances. Direct Deposit means a deposit to an account holder’s SoFi Checking or Savings account, including payroll, pension, or government payments (e.g., Social Security), made by the account holder’s employer, payroll or benefits provider or government agency (“Direct Deposit”) via the Automated Clearing House (“ACH”) Network during a 30-day Evaluation Period (as defined below). Deposits that are not from an employer or government agency, including but not limited to check deposits, peer-to-peer transfers (e.g., transfers from PayPal, Venmo, etc.), merchant transactions (e.g., transactions from PayPal, Stripe, Square, etc.), and bank ACH funds transfers and wire transfers from external accounts, do not constitute Direct Deposit activity. There is no minimum Direct Deposit amount required to qualify for the stated interest rate.

SoFi members with Qualifying Deposits can earn 4.60% APY on savings balances (including Vaults) and 0.50% APY on checking balances. Qualifying Deposits means one or more deposits that, in the aggregate, are equal to or greater than $5,000 to an account holder’s SoFi Checking and Savings account (“Qualifying Deposits”) during a 30-day Evaluation Period (as defined below). Qualifying Deposits only include those deposits from the following eligible sources: (i) ACH transfers, (ii) inbound wire transfers, (iii) peer-to-peer transfers (i.e., external transfers from PayPal, Venmo, etc. and internal peer-to-peer transfers from a SoFi account belonging to another account holder), (iv) check deposits, (v) instant funding to your SoFi Bank Debit Card, (vi) push payments to your SoFi Bank Debit Card, and (vii) cash deposits. Qualifying Deposits do not include: (i) transfers between an account holder’s Checking account, Savings account, and/or Vaults; (ii) interest payments; (iii) bonuses issued by SoFi Bank or its affiliates; or (iv) credits, reversals, and refunds from SoFi Bank, N.A. (“SoFi Bank”) or from a merchant.

SoFi Bank shall, in its sole discretion, assess each account holder’s Direct Deposit activity and Qualifying Deposits throughout each 30-Day Evaluation Period to determine the applicability of rates and may request additional documentation for verification of eligibility. The 30-Day Evaluation Period refers to the “Start Date” and “End Date” set forth on the APY Details page of your account, which comprises a period of 30 calendar days (the “30-Day Evaluation Period”). You can access the APY Details page at any time by logging into your SoFi account on the SoFi mobile app or SoFi website and selecting either (i) Banking > Savings > Current APY or (ii) Banking > Checking > Current APY. Upon receiving a Direct Deposit or $5,000 in Qualifying Deposits to your account, you will begin earning 4.60% APY on savings balances (including Vaults) and 0.50% on checking balances on or before the following calendar day. You will continue to earn these APYs for (i) the remainder of the current 30-Day Evaluation Period and through the end of the subsequent 30-Day Evaluation Period and (ii) any following 30-day Evaluation Periods during which SoFi Bank determines you to have Direct Deposit activity or $5,000 in Qualifying Deposits without interruption.

SoFi Bank reserves the right to grant a grace period to account holders following a change in Direct Deposit activity or Qualifying Deposits activity before adjusting rates. If SoFi Bank grants you a grace period, the dates for such grace period will be reflected on the APY Details page of your account. If SoFi Bank determines that you did not have Direct Deposit activity or $5,000 in Qualifying Deposits during the current 30-day Evaluation Period and, if applicable, the grace period, then you will begin earning the rates earned by account holders without either Direct Deposit or Qualifying Deposits until you have Direct Deposit activity or $5,000 in Qualifying Deposits in a subsequent 30-Day Evaluation Period. For the avoidance of doubt, an account holder with both Direct Deposit activity and Qualifying Deposits will earn the rates earned by account holders with Direct Deposit.

Members without either Direct Deposit activity or Qualifying Deposits, as determined by SoFi Bank, during a 30-Day Evaluation Period and, if applicable, the grace period, will earn 1.20% APY on savings balances (including Vaults) and 0.50% APY on checking balances.
