Honestly, the moment you get engaged, everyone starts asking about the dress or the venue. Nobody asks about the legal paperwork. But if you’re sitting there wondering how long does it take to get a prenuptial agreement, you’re already ahead of the curve. Most couples treat a prenup like a last-minute errand—something to tick off a week before the wedding like ordering party favors. That is a massive mistake.
If you want the short answer: it usually takes between three and six weeks.
But life is rarely that simple, is it? If you have complex assets, a business, or an inheritance you’re trying to protect, you might be looking at months. It’s not just about typing up a document. It’s about the "disclosure" phase, which is basically a financial colonoscopy. You have to show everything. Every bank account, every debt, every random bit of crypto you bought in 2021. If you hide something, the whole agreement can be tossed out later.
The Timeline Trap: Why Three Months is the Gold Standard
Most family law experts, like those at the American Academy of Matrimonial Lawyers (AAML), suggest starting the process at least three to six months before the wedding date. Why so early? Because of the "duress" factor.
Imagine this. You’re three days away from saying "I do." The flowers are at the venue. Your Great Aunt Martha just flew in from Chicago. Your partner hands you a 30-page legal document and says, "Sign this or the wedding is off." In many states, like California or New York, a judge might look at that and say the agreement is invalid because you were under extreme emotional pressure.
You need breathing room.

The first week is usually spent finding lawyers. Yes, plural. You generally cannot use the same lawyer for both people. That’s a conflict of interest. In fact, in many jurisdictions, if both parties don't have independent legal counsel, the prenup is basically a piece of scrap paper. You spend week one interviewing, paying retainers, and setting expectations.
Then comes the "Financial Disclosure" phase. This is the part that everyone underestimates. You have to gather statements. You need valuations for businesses. If you own a house, you might need a fresh appraisal. This can take two weeks easily if you aren't organized.
The Negotiating Table
Once the draft is created, the ping-pong match starts. Your lawyer sends it to their lawyer. Their lawyer finds three clauses they hate. They send it back.
This is where the clock really starts ticking. If you and your partner are on the same page about everything—say, "what's mine is mine, what's yours is yours"—it moves fast. But if you’re arguing over future alimony (spousal support) or who gets the dog, weeks can slip by.
It’s an emotional process. It’s not just business. You’re talking about the "what if" of a divorce while you’re supposed to be in the "honeymoon phase." People get sensitive. Sometimes a couple needs to step away from the negotiations for a few days just to remember they actually like each other.

Legal Requirements That Slow Things Down
Different states have different rules. In California, for example, there is a "seven-day rule." Under the California Family Code, there must be at least seven days between the time a person is first presented with the final agreement and the time it is signed. You can't skip this. If you sign it on day six, you might have just wasted all that money on legal fees because a court could throw it out.
Then there’s the "Unconscionability" check. Lawyers have to make sure the deal isn't so one-sided that it’s offensive to the court. If one person leaves with $10 million and the other is left on food stamps, a judge is going to have a field day. Refining these terms to be "fair" takes time.
What if you’re already at the one-month mark?
Don't panic, but move fast.
If you are 30 days out from your wedding and haven't started, you are in the "red zone." You can still get it done, but you’ll likely pay a premium in legal fees for the rush. You’ll also be incredibly stressed.
Some couples decide to pivot to a postnuptial agreement if they run out of time. This is an agreement signed after the wedding. Be careful here. Postnups are often harder to enforce than prenups. The legal standards are stricter because once you're married, you have a fiduciary duty to one another.

Real-World Factors Influencing the Speed
- Asset Complexity: If you own a multi-state LLC or have intellectual property, your lawyer has to figure out how to categorize those. That’s not a one-hour job.
- The "Other" Lawyer: You can be as fast as you want, but if your partner's lawyer is a "shark" who wants to bill more hours or is just slow at returning emails, you're stuck.
- International Elements: If one of you is from another country or has assets abroad, you might need to ensure the prenup is enforceable in multiple jurisdictions. This adds layers of complexity and time.
- Child Provisions: You generally can't pre-determine child custody in a prenup (the court always decides based on the "best interests of the child"), but people still try to sneak things in, which leads to legal arguments and delays.
How to Speed Up the Process
If you want to know how long does it take to get a prenuptial agreement because you're in a hurry, there are ways to grease the wheels.
Be transparent. Immediately.
Create a spreadsheet. List every asset, every debt, and every source of income. Attach the last three months of statements for everything. If you hand this to your lawyer on day one, you save a week of back-and-forth.
Talk to your partner before you call the lawyers. If you agree on the big picture—like keeping pre-marital property separate—tell your lawyers that. If the lawyers know you aren't looking for a fight, they can use a more standard, collaborative template rather than starting from scratch with "combat" language.
The Cost of Rushing
Rushing leads to mistakes. A misspelled name, a forgotten bank account, or a clause that violates state law can render the entire document useless. You don't want to spend $5,000 and 20 hours of stress on a document that won't actually protect you in ten years.
Also, consider the "Sunset Clause." Some people add a clause that says the prenup expires after 10 or 20 years. Discussing these nuances takes time, but it often makes the agreement more palatable for the person who is "giving up" more in the short term.
Actionable Steps to Take Right Now
- Audit your finances tonight. Pull your credit report and gather your investment statements so you aren't hunting for passwords when the lawyer's clock is ticking at $400 an hour.
- Schedule a "money talk." Sit down with your fiancé and discuss the big goals. Do you want to pool your incomes? Keep them separate? Who stays in the house if things go south?
- Book your initial consultations. Don't wait for the "perfect time." Most family law attorneys offer a 30-minute consult. Use it to see if you even like their vibe.
- Set a "hard deadline" for signing. Aim to have the final document signed and notarized at least 30 days before the wedding. This allows you to actually enjoy your wedding month without talking about divorce settlements.
- Check your state's specific laws. Research whether your state follows the Uniform Premarital Agreement Act (UPAA), as this will dictate how "bulletproof" your timeline needs to be.
The reality is that a prenuptial agreement is a contract of ghost stories—you're planning for a future that you hope never happens. But just like a fire drill, the point isn't the speed of the drill; it's making sure the exits actually work when you need them. Give yourself the gift of time so the process brings you closer together instead of driving a wedge between you before the cake is even cut.
