What Is a Prenup? A Plain-English Guide for Gen Z and Millennials (2026)
A prenup used to be something only the ultra-wealthy worried about. Not anymore.
Many couples from Gen Z and millennial generations are signing prenuptial agreements at higher rates than previous generations — and the reasons aren’t about distrust. They’re about financial reality. People are marrying later (the median age is now 30 for men and 28 for women), which means they arrive at marriage with more assets, more debt, and more complex financial lives. Student loans, side businesses, crypto wallets, and years of independent savings all need to be accounted for.
Getting a prenup is one of the most practical financial decisions a couple can make. This guide explains what prenuptial agreements cover, what they can’t do, how to get a prenup, and what it costs — without the legalese.
What is a prenup?
A prenup — short for prenuptial agreement, also referred to as a premarital agreement — is a legal contract signed by two people before they get married. It sets out how assets, debts, and property will be handled if the marriage ends in divorce or death.
Prenuptial agreements don’t predict failure. They’re a contract that formalizes open communication about finances before the wedding, when both parties are clear-headed and on good terms. Like any contract, prenuptial agreements work best when both parties understand exactly what they’re signing.
What does a prenup cover?
A well-drafted prenuptial agreement can address a wide range of financial matters. Understanding what’s included helps both parties get on the same page before signing.
Assets and separate property
A prenup can designate property one person owned before the marriage as separate property — meaning it stays theirs alone if the marriage ends. This applies to savings, investments, real estate, and other assets either partner brings into the marriage.
Debt allocation
Student loans, credit card balances, and other debts can be assigned to the spouse who incurred them. This protects one spouse from becoming responsible for the other’s pre-existing financial obligations. It also clarifies which debts belong to which party if the couple’s assets and liabilities become intertwined over time.
Spousal support and alimony
Prenuptial agreements can define whether alimony or spousal support will be paid after a divorce, and under what conditions or limits. Both parties can agree in advance on specific terms that reflect what’s fair to each spouse.
Business interests and digital assets
If one or both parties owns a business, a prenup can protect that ownership and define how business value is treated in a divorce. The agreement can also address crypto and digital assets — an area where courts are still developing consistent rules, and where signing a clear agreement in advance avoids expensive disputes later.
Inheritance and children from previous relationships
Prenuptial agreements are especially useful when one or both parties have children from a previous relationship or significant assets they want to pass to heirs. The agreement can protect inheritance plans and ensure that provisions for children from prior marriages are honored, even if the current marriage ends.
What a prenup can’t do
Prenuptial agreements have real limits. Courts will typically refuse to enforce provisions that:
- Determine child support or child custody. These decisions are made by a court based on the best interests of the child at the time of divorce — prenuptial agreements can’t override that process.
- Waive rights to public benefits. No contract can require one spouse to give up eligibility for government assistance.
- Include illegal terms. Any provision that violates state law is unenforceable, regardless of what both parties agreed to in writing.
- Address non-financial personal matters. Lifestyle clauses — rules about chores, in-laws, or personal habits — are routinely rejected by courts.
Prenuptial agreements also won’t hold up if they were signed under duress, without full financial disclosure, or without each party having a reasonable opportunity to review the contract before signing. Presenting a prenup the night before the wedding is a reliable way to have it thrown out in court later. Most states have adopted some version of the Uniform Premarital Agreement Act, which sets baseline standards for enforceability — but the specifics vary, so checking your state’s requirements is essential.
Why Gen Z and millennials are signing prenups
For earlier generations, prenuptial agreements carried a stigma. Today that’s changing fast, and for practical reasons.
Student loan debt. Many couples arrive at marriage carrying significant debts from their education — federal student loan borrowing has grown steadily over the past two decades, making debt allocation one of the most common reasons younger couples seek prenuptial agreements. A prenup can establish that each party remains responsible for their own pre-marital debt, preventing disputes over who owes what if the marriage ends.
More assets at stake. Marrying at 30 instead of 22 means arriving with a decade of savings, retirement contributions, and investment growth. Signing a prenuptial agreement protects what each person’s assets represent — years of independent financial work.
Side businesses and gig income. Many younger earners run freelance operations, content channels, or side ventures alongside traditional employment. Prenuptial agreements can define whether those business interests count as marital property and how their future value is treated in a divorce.
Digital assets. Crypto, NFTs, and other digital assets are hard to divide without a written plan. Spelling out how they’re categorized in a prenuptial agreement prevents costly disputes later.
Open communication as a value. For many younger couples, discussing finances before marriage isn’t awkward — it’s expected. Prenuptial agreements formalize what’s already part of the conversation.
How to get a prenup
The process of getting a prenup is more straightforward than many couples expect. The key is starting early — at least six to eight weeks before the wedding — to avoid any claim of duress at the signing stage.
- Start the conversation with your future spouse. Bring it up months before the wedding, not days. Both parties need time to think, ask questions, and review the agreement without feeling pressured.
- Each party hires their own family law attorney. Prenuptial agreements signed without independent legal counsel are more vulnerable to challenge. Each person should have their own lawyer reviewing the contract before signing.
- Disclose all finances fully. Both parties must provide complete, honest disclosure of assets, debts, income, and liabilities. Hiding assets during this process can lead to the entire agreement being invalidated — not just the relevant provision.
- Draft and negotiate the agreement. A family law attorney will draft the terms and work with the other party’s attorney to negotiate any disputed provisions.
- Review, sign, and notarize. Both parties sign the contract, typically in front of a notary public or witnesses depending on the state’s specific requirements. Keep the original somewhere safe and make sure each party has a copy.
- Review it periodically. Prenuptial agreements should be revisited after significant life events — the birth of a child, a major inheritance, a new business — to ensure the terms still reflect both parties’ circumstances.

How much does a prenup cost?
Prenup cost varies depending on complexity and how you approach the process.
Attorney-drafted: Working with a family law attorney typically costs between $1,000 and $3,000 or more for a complete prenuptial agreement, with some complex agreements running higher. Many attorneys bill hourly, so the total depends on how much negotiation is involved. For couples with significant assets, business interests, or complicated financial circumstances, hiring a family law attorney is the most enforceable route.
Template-based: For couples with straightforward finances, the average cost of a prenuptial agreement using an online template is approximately $650. A well-drafted prenuptial agreement template is attorney-prepared, covers the essential provisions, and can be completed in a fraction of the time. US Legal Forms provides state-specific prenuptial agreement templates, including options for couples with prior marriages or business interests.
Whatever approach you take, don’t skip legal review entirely. Even template-based prenuptial agreements benefit from a one-time consult with a family law attorney before both parties sign.
Do you need a family law attorney?
Most states don’t legally require either party to have their own lawyer when signing prenuptial agreements. But independent counsel is strongly recommended — and for good reason.
Courts scrutinize prenuptial agreements for fairness. If one party didn’t have their own lawyer, a court may be more willing to find that the agreement was unconscionable or that the signing was coerced. Having each party represented by their own family law attorney is the clearest way to demonstrate that both parties understood what they were agreeing to and signed the contract voluntarily.
It’s also worth noting that family law requirements vary significantly by state. A family law attorney practicing in your state will know the specific requirements — witness counts, notarization rules, required disclosure formats — that apply to prenuptial agreements where you live.
What if you’re already married? Postnuptial agreements
A postnuptial agreement covers the same ground as a prenup — property division, debt, spousal support — but is signed after the wedding rather than before. Many couples pursue postnuptial agreements after a significant change in finances, the launch of a new business, an inheritance, or simply to formalize financial expectations they didn’t address before getting married.
Postnuptial agreements are valid in most states, but courts apply slightly more scrutiny than they do to prenuptial agreements, given the dynamics of an existing marriage. Independent counsel for each spouse is just as important.

Not planning to marry? Cohabitation agreements
More Gen Z couples are choosing to live together without getting married. Without a marriage license, there are no automatic legal protections if the relationship ends — no property division rules, no spousal support, no clear ownership of shared assets.
A cohabitation agreement fills that gap. It functions like a prenup for unmarried couples, defining who owns what, how shared expenses are handled, and what happens to jointly purchased property if the relationship ends. Many couples use cohabitation agreements as a practical framework while they’re deciding whether marriage is part of their plan.

Frequently asked questions
Is getting a prenup difficult?
The process of getting a prenup is straightforward when both parties start early and approach it with open communication. The main requirements — full financial disclosure, independent legal counsel, and signing well before the wedding — are all manageable with a bit of planning. The most common difficulty is emotional, not legal: bringing up the conversation. Once both parties are on the same page, the drafting and signing process is typically uncomplicated.
How much money do you have to make for a prenup?
There’s no income threshold for prenuptial agreements. Couples with significant assets benefit most from a prenup, but any couple with debts, property, a business, or financial rights worth protecting has good reason to consider one. Even couples with modest finances can benefit from the clarity prenuptial agreements create around debt responsibility and property ownership.
How much should it cost to get a prenup?
The average prenup cost in the United States is approximately $650 for a template-based agreement. Attorney-drafted prenuptial agreements typically run from $1,000 to $3,000 depending on complexity, location, and how much negotiation is involved between the parties. More complex agreements — involving business ownership, significant assets, or prior marriages — may cost more.
Can I write a prenup myself?
Technically, you can write your own prenup — prenuptial agreements don’t legally require an attorney in most states. However, a prenup drafted without legal expertise is more likely to contain errors that make it unenforceable, and courts may be less inclined to uphold it if one party later challenges it. Using an attorney-drafted template is a practical middle ground: it provides a legally sound structure that both parties can complete, review, and then have checked by a family law attorney before signing.
The bottom line
A prenup isn’t a sign of distrust — it’s a sign that both parties understand their financial lives and want to protect each other clearly. For Gen Z and millennials who marry later, carry more debt, and build more complex financial lives before the wedding, prenuptial agreements are less a precaution and more a practical necessity.
US Legal Forms has attorney-drafted prenuptial agreement templates for every state, along with postnuptial and cohabitation agreements for couples at every stage.
