Prenup Basics: Start With the Financial Conversation Before the Legal Draft

A prenup is a state-law legal agreement, not a generic financial template. Start with a clear inventory of assets, debts, businesses and expectations, then use qualified counsel for the agreement itself.

The answer in 30 seconds
  • 1A prenuptial agreement is a legal contract made in contemplation of marriage. What it can cover and what formalities make it enforceable depend on state law.
  • 2The practical starting point is financial clarity: assets, debts, business interests, expected inheritances, support obligations and how property will be handled during marriage or at separation/death.
  • 3Do not use a template as a substitute for state-specific legal advice. Timing, execution formalities, disclosure, voluntariness and the substance of the agreement can matter.
  • 4New York is one example: state law requires qualifying marital agreements to be written, subscribed and formally acknowledged/proven. Other states can use different rules.

Financial-disclosure inventory

Start with a clear balance sheet before discussing legal terms.

A prenup is a legal agreement, but the financial conversation starts with identifying assets, debts, ownership and the items each person has actually reviewed.

ASSETSwhat you own−DEBTSwhat you owe=NETWORTH
Total assets entered$500,000
Total debts entered$75,000
Combined net position$425,000
Disclosure items remaining4

This is an inventory prompt, not a prenup generator or legal opinion. Do not store account numbers, passwords or Social Security numbers in MFA.

This does not decide what is separate or marital property and does not test enforceability. State law and legal advice control those questions.

The short answer

A prenuptial agreement is a legal contract made in contemplation of marriage. What it can cover, how it must be signed and what makes it enforceable depend on state law.

That means the useful first step is not downloading a template. It is building a clear financial picture and identifying the questions the couple actually wants the agreement to address.

MFA can help organize the financial inventory. It should not try to generate the legal agreement.

Start with financial clarity

Before drafting legal terms, each person should understand the household balance sheet. Useful categories include cash and investments, retirement accounts, real estate and mortgages, student loans and other debts, closely held businesses, equity compensation, expected inheritances or family gifts, existing support obligations, life insurance and estate documents.

You do not need to store account numbers or sensitive credentials in MFA. For planning purposes, a description and approximate value can be enough to organize the conversation.

Inventory is not legal classification

An asset being titled in one person's name today does not automatically answer how it will be treated years later under every state's law. Contributions, commingling, appreciation, marital labor and contractual language can matter.

So labels such as “Partner A,” “Partner B” and “joint” in MFA are an inventory, not a legal conclusion that property is separate or marital.

Questions worth discussing

How should premarital assets be treated? What happens to property purchased together? How are premarital debts handled? What if one spouse leaves work to care for children? How are business interests protected or shared? How should inheritances and family gifts be treated? Are there estate-planning commitments between spouses? How should support questions be approached within applicable law?

The goal is not to “win” the prenup. It is to surface expectations while the relationship is cooperative.

State law controls the formalities

New York illustrates why generic templates can be dangerous. New York Domestic Relations Law §236 imposes formal requirements for qualifying agreements made before or during marriage, including writing, subscription by the parties and the required acknowledgment or proof. Other states can use different statutes, standards and case law.

A document that fits one jurisdiction's practice should not be assumed valid everywhere.

Timing and process matter

Rushing a document immediately before a wedding can create practical and legal problems. A thoughtful process gives both people time to understand the financial information, ask questions and obtain advice.

Independent legal counsel for each person is often a prudent process choice when there is a large wealth difference, business ownership, family money or complex support provisions. Whether separate counsel is legally required is jurisdiction-specific.

Coordinate the rest of the plan

A prenup discussion often reveals follow-up work involving wills and trusts, beneficiary designations, life insurance, real-estate titling and business agreements. The contract and estate plan should not accidentally point in opposite directions.

Run the inventory

Use the MFA lab to build a high-level assets, debts and disclosure checklist, then take the organized questions to qualified counsel in the relevant state.
