How to Protect Assets with a Prenuptial Agreement

Nobody gets engaged and immediately thinks, "I should plan for how this might end." That's exactly why prenups have such a bad reputation. But talk to any family law attorney and they'll tell you the same thing: a prenuptial agreement isn't a bet against your marriage. It's a financial plan, drawn up while everyone still likes each other, for a situation nobody wants to think about later.

If you own a home, run a business, have retirement savings, or expect an inheritance, a prenup is one of the few legal tools that lets you decide in advance how those assets get treated — instead of leaving it up to a judge in your state, using rules you never chose.

What a prenup actually does

A prenuptial agreement (also called a premarital agreement) is a contract signed before marriage that spells out how property, debts, and sometimes spousal support will be handled if the marriage ends in divorce or death. Once you're married, the same kind of contract is called a postnuptial agreement, and it works similarly, though a few states treat it with extra scrutiny.

At its core, a prenup does three things:

• Defines separate property. It states which assets belong to each spouse individually and stay that way, regardless of what happens during the marriage.

• Sets rules for marital property. It can decide how anything acquired during the marriage — a house, a joint investment account, a business that grows in value — gets split.

• Addresses debt. It can protect one spouse from being responsible for the other's premarital debt, like student loans or a business line of credit.

Without a prenup, these questions get answered by your state's default divorce laws. In the nine community property states — including California, Texas, and Arizona — assets acquired during marriage are generally split 50/50, no matter who earned or paid for what. Everywhere else, courts use "equitable distribution," which sounds fair but doesn't mean equal. A judge weighs factors like each spouse's income, contributions, and the length of the marriage, and the outcome can be hard to predict. A prenup replaces that guesswork with terms you actually agreed to.

Who actually needs one

The old assumption was that prenups were for the wealthy. That's changed. A Harris Poll conducted for Bloomberg this year found interest in prenups rising across income levels, not just among the rich, and younger couples are increasingly requesting them before marriage.

A prenup is worth serious consideration if you:

• Own a home, retirement account, or investment portfolio before the marriage

• Run a business or hold equity in one

• Expect to inherit money or property

• Have children from a previous relationship and want to protect their inheritance

• Are marrying someone with significant debt

• Have a much higher income or net worth than your future spouse

Even without any of these, some couples just want clarity. Knowing exactly where you stand financially can prevent a lot of arguments down the road, prenup or not.

What a prenup can and can't cover

This trips people up constantly. A prenup is a financial contract, not a general-purpose life plan, and courts will strike down clauses that go beyond that scope.

Prenups can cover:

• Division of property and assets

• Responsibility for debts

• Spousal support (alimony) terms, within limits set by state law

• Rights to a family business

• How property passes on death, alongside a will or trust

• Financial responsibilities during the marriage, like how bills get split

Prenups cannot cover:

• Child custody or child support — courts decide these based on the child's best interests at the time, not on an agreement signed years earlier

• Anything that encourages divorce, like a clause paying one spouse extra for filing

• Illegal terms or anything that violates public policy

• Personal, non-financial matters — clauses about chores, weight, or how often you visit in-laws generally won't hold up and can undermine the agreement's credibility if a judge sees them

If a court finds a prenup tries to control custody or looks more like a punishment than a fair contract, it can throw out the whole document, not just the problem clause. Keep it financial.

The legal groundwork that makes a prenup enforceable

A prenup is a legal contract, and like any contract, it can be challenged. Courts have thrown out agreements that were signed under pressure, hidden information, or weren't fair to begin with. To hold up, most states expect the following.

Full financial disclosure. Both spouses need to lay out their assets, debts, and income honestly. Hiding a bank account or a second property is one of the fastest ways to get a prenup invalidated later.

Separate attorneys. Each spouse should have their own lawyer, not share one. If your fiancé's attorney drafts the agreement and you sign it without independent legal advice, a court may later decide you didn't fully understand what you agreed to. California actually requires independent counsel for anyone waiving spousal support.

No pressure, no last-minute signing. Signing a prenup the night before the wedding, with a photographer waiting outside, is a classic way to get it challenged for duress. Give it weeks, not hours. California requires at least seven days between when the agreement is presented and when it's signed.

Fair terms, both now and later. An agreement that leaves one spouse with essentially nothing, especially after a long marriage, is more likely to be reviewed and rejected. Some states apply a "second look" at the time of divorce to check the agreement is still not unconscionable.

Written and signed. Verbal agreements about property don't count. It needs to be in writing, signed by both parties, and in some states, notarized.

Twenty-nine states plus DC have adopted a version of the Uniform Premarital Agreement Act or its successor, the Uniform Premarital and Marital Agreements Act, which standardizes many of these rules. The other states set their own standards through case law and individual statutes, so what's required in Texas isn't identical to what's required in New York. This is one of the main reasons a prenup should be drafted by a lawyer licensed in your state, not copied from a generic template.

How to actually get one done

Start the conversation early. Bringing up a prenup two weeks before the wedding almost guarantees it feels like an ultimatum. Raise it months in advance, framed as a shared financial planning step rather than a demand.

Get organized. Pull together a list of your assets, debts, income, and anything you're bringing into the marriage — property, retirement accounts, business interests, inheritance expectations.

Hire your own attorney. Each spouse needs separate legal representation. It costs more than a DIY template, but it's the difference between a document that protects you and one that falls apart the moment it's tested.

Decide what actually matters to you. Not every asset needs a clause. Focus on the things that would genuinely complicate a split — a business, a home you owned before the marriage, an inheritance you want to keep separate.

Sign with time to spare. Finalize the agreement well before the wedding date, with both parties reviewing it calmly rather than rushing under pressure.

Revisit it periodically. Life changes — a new business, a child, a big inheritance. Some couples update their prenup, or add a postnuptial agreement, when circumstances shift significantly.

The bottom line

A prenuptial agreement won't make a marriage more or less likely to last. What it does is remove financial uncertainty from an already emotional situation, protecting the assets you built before the relationship and giving both spouses clear expectations from day one. Done properly, with honest disclosure and independent legal advice on both sides, it's less a symbol of distrust and more a practical safeguard, the same way people insure a house they hope never burns down.

If you're considering one, talk to a family law attorney licensed in your state early. State rules vary enough that what protects your assets in one place might not hold up in another.
