A prenuptial agreement, commonly called a prenup, is a written agreement entered into by two people before marriage that establishes how certain financial and property matters may be handled during the marriage or if the marriage ends.
Prenuptial agreements can address property ownership, debt responsibilities, financial disclosures, business interests, inheritances, and other financial matters permitted under applicable law.
Requirements vary substantially by state. A valid agreement may depend on factors such as voluntary consent, financial disclosure, written documentation, timing, fairness, and proper execution.
Marriage can combine financial interests while also creating legal rights and responsibilities.
A prenuptial agreement can provide a framework for discussing:
Separate and marital property
Existing debts
Future financial obligations
Business ownership
Inheritance interests
Real estate
Investment accounts
Retirement assets
Financial responsibilities during marriage
Property division if the marriage ends
The agreement should address matters that are legally permitted in the applicable jurisdiction.
Preparing a prenup can encourage both parties to review their financial circumstances before marriage.
Financial information may include:
Bank accounts
Investment accounts
Retirement accounts
Real estate
Business interests
Loans
Credit-card obligations
Tax liabilities
Personal property
Existing financial agreements
Full and accurate financial disclosure can be an important part of the process. The specific disclosure requirements depend on applicable state law and the circumstances of the agreement.
One major purpose of a prenuptial agreement can be establishing how property is treated.
Separate property may include assets that a person owns before marriage or property that remains separate under applicable law.
Marital property generally refers to property acquired during marriage, although definitions and exceptions vary by state.
A prenup can establish agreed rules for classifying certain assets, subject to applicable legal requirements.
Prenuptial agreements can be particularly relevant when one or both parties have significant assets or business interests.
Topics may include:
Ownership interests
Business income
Partnership interests
Corporate shares
Intellectual property
Future business growth
Existing business obligations
Succession considerations
A prenup does not automatically eliminate the rights of third parties, creditors, business partners, or other people who are not parties to the agreement.
Business owners should also consider how the agreement interacts with operating agreements, shareholder agreements, partnership documents, trusts, and estate plans.
A prenup may address how certain debts are treated.
Potential topics include:
Student loans
Credit-card debt
Business debt
Personal loans
Mortgages
Tax obligations
Guarantees and other financial commitments
The agreement can establish expectations between spouses, but it generally does not automatically change a creditor's rights under an existing contract.
Prenuptial agreements can also interact with estate planning.
People may use estate-planning documents such as:
Wills
Trusts
Beneficiary designations
Powers of attorney
Healthcare directives
A prenup should be coordinated with these documents where appropriate.
For example, a person's estate plan and beneficiary designations may need to be reviewed after marriage so that they remain consistent with intended financial arrangements and applicable law.
Prenuptial agreements can contain provisions addressing:
Property classification
Separate-property rights
Debt allocation
Business interests
Financial disclosure
Inheritance
Estate-planning coordination
Financial responsibilities
Dispute-resolution provisions
Applicable law
Not every provision is enforceable in every state. Certain provisions concerning child custody or child support, for example, may be subject to separate legal standards and court review.
Requirements vary by state, but important considerations can include:
Written agreement
Prenuptial agreements are generally written contracts rather than informal understandings.
Voluntary agreement
Both parties generally need to enter into the agreement voluntarily.
Financial disclosure
Financial disclosure can be important for informed decision-making and enforceability.
Independent legal advice
Each person may benefit from obtaining independent legal advice, particularly when the agreement contains significant financial provisions.
Adequate time
Presenting an agreement immediately before a wedding can create questions about voluntariness and fairness depending on the circumstances and applicable law.
Proper execution
The agreement should be signed and executed according to applicable state requirements.
A prenuptial agreement is generally entered into before marriage.
A postnuptial agreement is generally entered into after marriage.
Both can address certain financial and property issues, but their legal requirements and enforceability can differ.
| Prenuptial Agreement | Postnuptial Agreement |
|---|---|
| Created before marriage | Created after marriage |
| Establishes financial terms before marriage | Modifies or establishes financial terms during marriage |
| May address separate-property treatment | May address property acquired during marriage |
| Governed by applicable state law | Governed by applicable state law |
| Requires appropriate execution | Requires appropriate execution |
Before entering into a prenuptial agreement, each person can consider:
Creating a complete asset inventory
Listing existing debts
Gathering financial statements
Reviewing business ownership documents
Identifying estate-planning documents
Reviewing beneficiary designations
Allowing adequate time for discussion
Obtaining independent legal advice
Asking questions about unfamiliar provisions
Keeping signed documents securely
The goal should be informed decision-making rather than relying on assumptions about what the agreement means.
Prenuptial agreements are primarily governed by state law in the United States.
Relevant legal issues can include:
Contract formation
Voluntary consent
Financial disclosure
Procedural fairness
Unconscionability
Independent legal representation
Execution requirements
Property rights
Estate-planning provisions
State-specific enforceability standards
Some states have adopted versions of the Uniform Premarital Agreement Act (UPAA), while others follow different statutory or case-law frameworks.
Because requirements differ, a prenup prepared for one state may not necessarily produce the same result in another state.
Before signing, consider:
Identify all significant assets
List existing debts
Gather financial records
Review business interests
Review existing estate documents
Review beneficiary designations
Understand property classifications
Consider debt responsibilities
Allow adequate time for review
Obtain independent legal advice
Confirm applicable state requirements
Keep a properly executed copy
Useful resources for researching prenuptial agreements include:
State statutes and court resources
State bar association information
Family-law attorneys
Estate-planning attorneys
Financial professionals
Tax professionals
Business attorneys
Existing wills and trust documents
Business ownership agreements
Personal financial statements
Official state resources should be used to verify current requirements.
1. What is a prenuptial agreement?
A prenuptial agreement is a written contract between two people made before marriage that addresses certain financial and property matters according to applicable law.
2. Can a prenup protect assets owned before marriage?
A prenup can establish agreed treatment of certain property, but enforceability depends on state law, the agreement's terms, disclosure, voluntariness, execution, and other circumstances.
3. Does a prenuptial agreement cover debt?
A prenup can address how certain debts are treated between spouses. It generally does not automatically change the rights of creditors under separate contracts.
4. Should both people have separate attorneys?
Independent legal advice can help each person understand the agreement and their legal rights. The importance and requirements of separate representation vary by state and circumstances.
5. Can a prenup determine child custody or child support?
Prenuptial agreements generally cannot conclusively determine future child-custody or child-support outcomes because courts apply applicable laws and consider the child's interests when required.
A prenuptial agreement can provide a structured way for couples to discuss property, debt, business interests, inheritance, and other financial matters before marriage.
Effective preparation involves accurate financial information, adequate time for review, clear documentation, and attention to applicable state law. Coordination with estate plans, business documents, and beneficiary designations can also be important.
Because enforceability and legal requirements vary by jurisdiction, significant decisions involving a prenuptial agreement should be reviewed with appropriately qualified legal and financial professionals.
