How To Get A Prenup | The Timeline Most Couples Overlook

To get a prenup, partners should hire separate lawyers, disclose all assets, negotiate terms, and sign weeks before the wedding.

Most people assume a prenuptial agreement is something reserved for the ultra-wealthy or the distinctly unromantic. The reality is more practical. A prenup simply lets you and your partner decide how your finances — from real estate to retirement accounts to debt — will be handled if the marriage ends. It’s a planning tool, not a lack of trust.

The honest answer is that getting a prenup involves a clear, step-by-step process that takes time. The single biggest mistake couples make is waiting until the final weeks before the wedding, which can make the agreement vulnerable to legal challenge. Starting early gives you room to negotiate, get proper legal advice, and sign without pressure.

What a Prenup Actually Does

A prenuptial agreement is a legal document signed before marriage that spells out financial rights and responsibilities. Think of it as a financial blueprint for your marriage — and a safety net if things don’t work out. It covers assets like homes, investments, and retirement accounts, as well as debts you bring in or accumulate together.

One common misunderstanding is that a prenup is only about divorce. In reality, it can also define how you’ll handle finances during the marriage, such as which income pays for shared expenses and which stays separate. It can protect business interests, expected inheritances, and even set terms for spousal support (alimony).

However, a prenup cannot dictate child custody or child support — those decisions are reserved for courts based on the child’s best interest. It also can’t include anything illegal or that encourages divorce. The document must comply with your state’s laws to be enforceable, which is why working with a local family law attorney is so important.

Why You Might Hesitate to Bring Up a Prenup

Raising the topic of a prenup can feel awkward, even threatening, in a new relationship. Many people worry it signals a lack of commitment or an expectation of failure. But that fear often stems from misunderstanding what a prenup really is. Approaching the conversation with transparency and respect can help avoid damaging trust.

  • Fear of appearing untrusting: You might worry your partner will think you don’t believe in the marriage. Framing it as a practical plan for both of you — not a backup plan — can ease that tension.
  • Concern about cost: Legal fees for a prenup typically range from a few hundred to a few thousand dollars per person. That’s far less than the cost of litigating a contested divorce later.
  • Belief that prenups are only for the rich: There’s no minimum net worth required. Anyone with assets, debts, or family obligations — like children from a previous relationship — can benefit from the clarity a prenup provides.
  • Worry about killing romance: Having an open, honest conversation about money can actually strengthen your relationship by building financial transparency early.
  • Lack of understanding of benefits: A prenup isn’t just about asset division; it can simplify estate planning, protect against your spouse’s debts, and save thousands in legal fees down the line.

Once both partners understand the real purpose, the conversation becomes less intimidating. The key is to start early, be honest, and listen to each other’s concerns.

Step-by-Step: How to Get a Prenup

The first step is talking openly with your partner about finances and why you want a prenup. After that, each of you needs to hire your own separate family law attorney. This is non‑negotiable: using one lawyer for both parties is a common mistake that can make the prenup unenforceable. Fidelity’s prenuptial agreement definition explains that a valid prenup requires full financial disclosure and independent legal counsel for each person.

Once you have attorneys, the next step is sharing a complete picture of your finances — assets, debts, income, and anything else that matters. Hiding or even underestimating the value of an asset can lead a court to throw out the entire agreement. After disclosure, you negotiate the terms. This can take weeks, so don’t rush it.

Finally, both of you must sign the document voluntarily and with full understanding. It should be in writing and notarized. Signing a few weeks or months before the wedding gives you time to think and avoids the appearance of duress. A last‑minute signing — even a week before — is risky and more likely to be challenged later.

What a Prenup Can Cover What a Prenup Cannot Cover
Division of current and future assets (homes, investments, retirement accounts) Child custody arrangements
Responsibility for debts (student loans, credit cards, mortgages) Child support amounts
Spousal support (alimony) — amount and duration Any illegal provisions or those encouraging divorce
Protection of business interests and intellectual property Waiver of the right to inherit (requires separate estate planning)
How inheritance and gifts will be treated Day‑to‑day household decision‑making (unless specified)

As you can see, a prenup covers a broad range of financial matters but leaves child‑related issues to the courts. Tailor your agreement to your specific situation — a young couple with student debt will have different priorities than a business owner with complex assets.

Common Mistakes That Can Invalidate Your Prenup

Even a well‑intentioned prenup can fail if it’s not put together correctly. Courts look closely at how the agreement was created, not just what it says. Avoiding these errors is essential for enforceability.

  1. Not hiring separate attorneys. Each spouse must have their own lawyer. Sharing one attorney creates a conflict of interest that can make the prenup invalid.
  2. Incomplete or inaccurate financial disclosure. Courts require a full accounting of assets and debts. Hiding anything — even a small bank account — can sink the entire agreement.
  3. Signing under duress or too close to the wedding. If one party felt pressured to sign at the last minute, the prenup may be void. Leave at least a month between final signing and the wedding date.
  4. Failing to notarize the document. A prenup must be in writing and notarized to be legally binding. An oral agreement or unsigned draft has no force.
  5. Making the terms unconscionable. A prenup that is extremely one‑sided — for example, leaving one spouse with nothing after a long marriage — can be struck down by a judge.

A poorly drafted prenup often ends up costing more in legal fees than the original agreement was worth. Taking the time to do it right with proper counsel saves money and headaches later.

What Goes Into a Strong Prenup

A strong prenup is clear, complete, and fair. It begins with a full list of each person’s assets and debts, often attached as schedules to the agreement. It then spells out how those assets will be treated: which remain separate property, which become marital property, and how they’ll be divided if you divorce. The document also addresses spousal support — whether it will be paid, at what level, and for how long. Per Theknot’s talk to partner about prenup guide, the conversation should come first, long before any writing begins. Open communication sets the stage for a fair negotiation.

Both parties must fully read and understand the agreement before signing. Signing without reading is another common error that can lead to a later challenge. The prenup should also include a clause stating that each person had the opportunity to consult an attorney and voluntarily chose to sign.

Finally, a good prenup is future‑proofed. It can include provisions for how to handle changes in circumstances — like one spouse becoming a stay‑at‑home parent or starting a business. Some couples revisit and update their prenup every few years to keep it aligned with their lives. Flexibility strengthens enforceability.

Key Term What It Often Defines
Separate property Assets owned before marriage or received as gifts/inheritance during marriage
Marital property Assets acquired during marriage, subject to division
Alimony (spousal support) Whether support is waived or limited, and under what conditions
Debt allocation Which spouse is responsible for specific debts, including those incurred during marriage

The Bottom Line

Getting a prenup is a straightforward process if you approach it with the right mindset and enough time. The essential steps are: talk openly, hire separate attorneys, disclose everything, negotiate fairly, and sign well before the wedding. Avoid the common pitfalls of last‑minute timing, incomplete disclosure, and one‑sided terms. A well‑drafted prenup can save you significant legal fees, emotional stress, and uncertainty down the road.

State laws and family court practices vary widely, so a family law attorney licensed in your state — not a generic online template — is the right person to review your specific needs before you sign anything.
