What Prenuptial Agreement needs to be valid in Missouri

  • Both parties must voluntarily sign the agreement in writing.
  • The agreement must be in writing and signed by both spouses-to-be.
  • For enforceability, it's best to sign the agreement before the wedding, not after.
  • Signatures should be acknowledged before a notary public (though not required by statute, notarization adds evidence).
  • Each party should fully disclose their financial information, including income, debts, and assets.
  • Both parties should consult independent attorneys to ensure the agreement is fair and knowingly entered.

How to set up a Prenuptial Agreement in Missouri

  1. Begin by listing your assets, debts, and income. Decide what you want to protect, like property, business interests, or inheritances.
  2. Discuss your goals and concerns openly with your partner. Remember, a prenup is about planning, not predicting failure.
  3. Consider using a Missouri-specific prenup template as a starting point, but always have it reviewed by a lawyer to ensure it meets your needs.
  4. Hire separate lawyers experienced in Missouri family law. Each of you should get independent legal advice to avoid challenges later.
  5. Draft the agreement with your attorney, including all required financial disclosures and your own terms (within legal limits).
  6. Sign the agreement in the presence of a notary public, and keep copies for your records. Ensure it's signed well before the wedding date.

How much it costs

The cost of a prenuptial agreement in Missouri varies widely. If you both use the same attorney or a simple template, you might spend $1,000–$2,500. With separate lawyers and complex assets, costs can reach $5,000 or more. The peace of mind and potential savings in a divorce are often worth the investment.

Missouri Prenup Preparation Checklist

Before drafting your Missouri prenuptial agreement, gather the necessary documents and understand the legal requirements to ensure the agreement is valid and enforceable.

  • Obtain a copy of each party's full financial disclosure, including assets, debts, income, and expenses.
  • List all separate property (inheritance, gifts, prior assets) and decide how it will be treated in the agreement.
  • Ensure you have independent legal representation for both parties, as courts may scrutinize agreements without it.
  • Sign the agreement in the presence of a notary public (witnesses are not required but may add extra validity).
  • Plan to finalize the agreement before the wedding date, ideally with ample time for negotiation and review.
  • Consider potential future changes (e.g., children, career) and include provisions that are fair and not unconscionable.

Questions people ask

Are prenuptial agreements enforceable in Missouri?

Yes, Missouri courts generally enforce prenups if they are in writing, signed voluntarily, and include full financial disclosure. However, they are overturned if the agreement was unconscionable or if one party didn't have a fair opportunity to review it.

What can be included in a Missouri prenuptial agreement?

You can cover property division, alimony (spousal maintenance), and debt allocation. However, you cannot waive child support or include provisions about child custody, as courts prioritize the child's best interests.

When should we sign a prenup before the wedding?

It's crucial to sign before your wedding. Ideally, sign at least 30 days prior. Last-minute agreements signed the day before may raise questions about coercion or lack of consideration, making them harder to enforce.

Do we need a notary or witnesses for the signature?

Missouri law does not explicitly require notarization for a prenup to be valid, but notarizing signatures is a best practice. It creates a public record and strong evidence that both parties signed voluntarily. Witnesses are not required.
