Can A Prenuptial Agreement Protect Me?

Jul 6, 2026 | Asset Protection, Divorce, Family Law

Can a Prenuptial Agreement Protect My Business, Retirement Accounts and Other Assets?

If you own a business, have accumulated retirement savings, or are entering a marriage with significant assets, one of the smartest questions you can ask before your wedding day is this: Can a prenuptial agreement actually protect what I’ve built? The short answer is yes — but the strength of that protection depends entirely on how the agreement is drafted, whether it complies with Florida law, and whether it is entered in a manner designed to deflect arguments about enforceability. At Loftus Law in Sarasota, we work with individuals to draft prenuptial agreements that protect your assets.

What Is a Prenuptial Agreement Under Florida Law?

A prenuptial agreement — sometimes called a premarital agreement or antenuptial agreement or simply a “prenup” — is a legally binding contract entered into by two people before they marry. In Florida, prenuptial agreements are governed by the Florida Premarital Agreement Act (Chapter 61, Florida Statutes), which gives couples broad authority to define their financial rights and obligations in the event the marriage ends in divorce or death.

A properly drafted prenuptial agreement can address a wide range of financial matters, including:

  • Which property remains separate (non-marital) and which becomes marital in the event of divorce;
  • How a business or business interest will be valued and treated in a divorce;
  • Whether retirement accounts, investment accounts, or pension benefits accumulated before or during the marriage will be subject to division in a divorce;
  • Whether spousal support (alimony) will be waived, limited, or defined;
  • How debts will be allocated in a divorce; and,
  • Protections for inheritance and estate planning goals when one party predeceases the other during an intact marriage.

Can a Prenup Protect My Business?

Yes — and for many business owners, this is the single most important reason to consider a prenuptial agreement. Without a prenup, a business started before marriage can still become partially marital property if marital funds or marital effort contributed to its growth during the marriage. In Florida, courts apply an “active appreciation” analysis, which means that if a spouse’s labor or marital money helped increase the value of a business, the other spouse may have a claim to that increase in value.

A well-drafted prenuptial agreement can address this by:

Establishing the business as “Separate Property.” The agreement can specify that the business — including its current value and future appreciation — remains the sole property of the owning spouse, regardless of how it grows during the marriage.

Defining what happens if marital funds are invested in the business. If you anticipate reinvesting marital income into the business, the agreement can set forth how the investment of such marital funds will be treated upon divorce.

Protecting business partners and co-owners. When other people have an ownership stake in your company, a prenup can help prevent a divorce from disrupting the business by limiting what a non-owner spouse could claim.

Removing the need for disruptive business valuations. Without a prenup, a divorce involving a business often requires hiring competing forensic accountants and valuation experts, which can be expensive, time-consuming, and invasive for your business operations. A prenup can establish a valuation method or agreed-upon value in advance.

Can a Prenup Protect My Retirement Accounts?

Division of retirement accounts is one of the most frequently contested issues in a Florida divorce. Many people assume that because they contributed to a 401(k), IRA, or pension under their own name, it belongs solely to them. Under Florida’s equitable distribution law, however, that is not necessarily true.

In Florida, retirement assets accumulated during the marriage are considered marital property, subject to equal division — even if the account is only in one spouse’s name. Contributions made before the marriage may be segregated out as premarital, provided the  claiming spouse has proper documentation.  Transfer of a retirement asset (other than an IRA to IRA transfer) requires a separate Qualified Domestic Relations Order (“QDRO”) so as to avoid penalties which might otherwise be associated with the transfer.

A prenuptial agreement can address retirement accounts in several important ways:

Protecting pre-marital balances. The agreement can confirm that the value of your retirement accounts as of the date of marriage — plus any growth attributable to that pre-marital amount — remains your separate property.

Addressing contributions made during the marriage. You and your future spouse can agree on how retirement contributions made during the marriage will be treated: whether they remain separate, are split, or are handled in a specified way.

Protecting pension benefits. If you have a defined-benefit pension through a government employer, military service, or a long-term corporate position, or the like, a prenup can define the extent to which your spouse will or will not share in those future benefits.

What Makes a Prenuptial Agreement Enforceable in Florida?

A prenup that is not properly executed is a prenup that will not protect you. Florida courts will not enforce a prenuptial agreement that fails to meet certain requirements.

For an agreement to hold up:

Both parties must enter voluntarily. A prenup signed under duress, pressure, or manipulation is subject to challenge. Both parties must have independent legal counsel and adequate time to review the agreement before signing.

There must be full financial disclosure. Florida law requires that both parties have fair and reasonable full disclosure of each other’s property and financial obligations before signing. Hiding assets or misrepresenting your financial picture can invalidate the agreement. It is advisable to be fully transparent, to produce and disclose more rather than less.

The agreement must be in writing and signed. Verbal agreements are not enforceable. The prenup must be a written document signed by both parties before the marriage ceremony and certain formalities should be observed at the signing.

The terms must not be unconscionable. Courts will not enforce an agreement where the circumstances surrounding the signing were so egregious as to be unconscionable.

Proper timing matters. Presenting a prenuptial agreement to your soon-to-be spouse the night before the wedding creates significant risk of a later challenge based on duress or lack of time to review. The earlier the process begins, the stronger the protection. At Loftus Law, a lead time of at least two month is required.

What a Prenup Cannot Do in Florida

While prenuptial agreements are powerful tools, they do have limits. Under Florida law, a prenuptial agreement cannot:

  • Control any rights with respect to minor children – such as custody, timesharing or child support;
  • Violate public policy; or,
  • Waive rights to temporary alimony or temporary attorney’s fees, suit money or choses.

These limitations exist to protect the interests of children and to comply with the public policies of the State of Florida.

Postnuptial Agreements: An Option If You’re Already Married

If you are already married and have no prenuptial agreement, all is not lost. Florida also recognizes postnuptial agreements — contracts entered after the wedding that can address many of the same issues as would be addressed in a prenup. If you have recently acquired a business, received an inheritance, or are now approaching retirement, a postnuptial agreement may be an effective way to establish protections going forward.
