Most people think of a prenup as protecting what they already own. For many couples the bigger number is what they will earn after the wedding: salary, bonuses, equity grants, and the savings and investments those paychecks fund. Florida’s default rule treats those earnings as marital. This page explains the default, what a future-income clause can change, and where such clauses most often fail.

Quick Answer

Can a Florida prenup keep my future income, savings and investments separate?

Yes, if the agreement says so clearly and is signed properly. Without one, assets acquired during the marriage, including what either spouse earns and what those earnings buy, are generally marital under § 61.075(6)(a)1.a. Florida’s premarital agreement statute lets a couple set rights in property “whenever and wherever acquired” (§ 61.079(4)(a)1.), and § 61.075(6)(b)4. treats assets excluded by a valid written agreement as nonmarital. A prenup cannot adversely affect a child’s right to support (§ 61.079(4)(b)).

The Default Rule: What You Earn During the Marriage Is Marital

Florida divides property in a divorce by first sorting it into marital and nonmarital. § 61.075(6)(a)1.a. makes marital “Assets acquired and liabilities incurred during the marriage, individually by either spouse or jointly by them.” A salary deposited into an account in one spouse’s name, the brokerage account it funds, and the condo it later buys are all, by default, marital. So are retirement benefits accrued during the marriage: § 61.075(6)(a)1.e. covers “All vested and nonvested benefits, rights, and funds accrued during the marriage” in retirement, pension, profit-sharing and deferred compensation plans.

Income from work is treated differently from income produced by property you already owned. Under § 61.075(6)(b)3., income derived from nonmarital assets during the marriage stays nonmarital “unless the income was treated, used, or relied upon by the parties as a marital asset.” Dividends from premarital investments start out separate; a paycheck earned during the marriage does not. That gap is what a future-income clause addresses.

What a Future-Income Clause Can Cover (§ 61.079(4)(a))

Florida’s statute lists what a premarital agreement may address. The subjects that matter for earnings are rights in property “whenever and wherever acquired or located” (4)(a)1, the right to manage, spend and dispose of property (4)(a)2, the disposition of property on separation, divorce or death (4)(a)3, and spousal support (4)(a)4. Within those limits, a clause can address:

  • Salary and wages earned by each spouse during the marriage.
  • Bonuses and commissions, including amounts earned during the marriage but paid after a separation.
  • Equity compensation such as stock options and RSUs granted during the marriage. See our prenup guide for startup founders and equity.
  • Business profits and growth of a company one spouse runs. See prenups for business owners.
  • Savings and investment accounts funded only from one spouse’s own earnings, and what those accounts buy.
  • What happens at death to separately earned assets, alongside the divorce terms.

Separate Earnings, Shared Life: Deciding What to Share

Keeping all future income separate is one option, not the only one. Many couples keep each spouse’s earnings separate but agree that contributions to a joint household account are shared, or that a home bought together is marital however it was paid for. Others share earnings and keep only premarital assets and inheritances separate. Because § 61.079(4)(a)2. lets the parties decide how property is used and managed, the agreement can describe the arrangement that fits the marriage the couple actually plans to have.

The Commingling Trap

The clause sets the label; day-to-day money habits can still blur it. Separate earnings deposited into a joint account, used to pay down the mortgage on a home one spouse owned before the wedding, or put into property titled in both names create tracing disputes. Two rules in § 61.075(6) come up most: paying down a premarital mortgage with marital funds makes part of the property marital under a statutory formula (§ 61.075(6)(a)1.c.), and real property held as tenants by the entireties “is presumed to be a marital asset” (§ 61.075(6)(a)2.). A workable clause pairs the classification with practical rules: accounts in each spouse’s own name, a written formula for joint contributions, and records that make tracing straightforward. For the house side of this, see Florida prenup rules for real estate and property.

Retirement Accounts Need a Second Signature After the Wedding

A prenup can say that each spouse’s 401(k) or pension stays separate, but federal law adds a step for many employer plans. Under 29 U.S.C. § 1055(c)(2), a waiver of the spouse’s survivor benefit takes effect only if the spouse consents in writing, witnessed by a plan representative or a notary public. The Treasury regulation is explicit that a premarital agreement does not satisfy that consent requirement (26 C.F.R. § 1.401(a)-20, Q&A-28). An agreement can therefore include a commitment by the spouse to sign the plan’s own consent form after the wedding. Our prenup guide for 401(k)s, IRAs and pensions covers this in detail.

Where a Future-Income Clause Can Fail (§ 61.079(7))

A Florida court will not enforce a premarital agreement if the challenging spouse proves that they did not sign voluntarily, or that the agreement was the product of “fraud, duress, coercion, or overreaching” (§ 61.079(7)(a)1.–2.). A third ground applies when the agreement was unconscionable when signed and the spouse had no fair and reasonable disclosure, did not waive disclosure in writing, and had no adequate knowledge of the other’s finances (§ 61.079(7)(a)3.). For a future-income clause, that makes disclosure of current earnings central: salary, bonus history, equity grants and business interests. Two further limits apply whatever the agreement says: a court may still order support if a waiver would leave a spouse eligible for public assistance (§ 61.079(7)(b)), and child support cannot be adversely affected (§ 61.079(4)(b)). See also financial disclosure for a Florida prenup.

Death as Well as Divorce

Separately earned assets also need a plan for death. A surviving spouse’s rights to an elective share, homestead, intestate share and other spousal rights may be waived before marriage by a written agreement “signed by the waiving party in the presence of two subscribing witnesses” (§ 732.702(1)), and no disclosure is required for a waiver signed before the wedding (§ 732.702(2)). Coordinating the prenup with a will and beneficiary designations is covered in Prenup and will before the wedding.

Checklist for a Future-Income Clause

  1. A clear statement of which earnings stay separate: salary, bonuses, equity, business profits (§ 61.079(4)(a)1.).
  2. A rule for what is shared: a household account, a home bought together, or a defined portion of income.
  3. Account rules: separate accounts in each name, and how joint contributions are made and recorded.
  4. A plan for premarital property the earnings may touch, such as a mortgage paid from salary (§ 61.075(6)(a)1.c.).
  5. A commitment to sign retirement-plan spousal consents after the wedding (26 C.F.R. § 1.401(a)-20, Q&A-28).
  6. Full disclosure of current income, bonus history, equity grants and business interests (§ 61.079(7)(a)3.).
  7. Death-time terms coordinated with the estate plan, with two subscribing witnesses where § 732.702 applies.

Frequently Asked Questions

Is a prenup that keeps all future income separate enforceable in Florida?

It can be. Section 61.079(4)(a)1 lets couples contract on property “whenever and wherever acquired.” A court can refuse enforcement if the agreement was signed involuntarily, through fraud, duress, coercion or overreaching, or if it was unconscionable when signed and the challenging spouse also lacked fair disclosure, had not waived disclosure in writing and had no adequate knowledge of the other’s finances (§ 61.079(7)(a)). Clear drafting, full disclosure of current income and time to review reduce that risk.

Does a prenup cover income I earned and saved before the wedding?

Money earned and saved before the marriage is already nonmarital under § 61.075(6)(b)1, together with assets bought with it. The prenup’s job is to keep it identifiable: list it in the disclosure, state that it stays separate, and set account rules so premarital savings are not mixed with marital funds.

Can we share some income and keep the rest separate?

Yes. Many agreements keep each spouse’s earnings separate but create a shared account for household costs, or treat a home bought together as marital. Section 61.079(4)(a)2 lets the parties decide how property is used, managed and controlled, so the agreement can spell out exactly what is shared and what is not.

Can a prenup waive alimony along with future income?

A Florida prenup can modify or eliminate spousal support (§ 61.079(4)(a)4). Two limits apply: a court may still order support if the waiver would make a spouse eligible for public assistance (§ 61.079(7)(b)), and no premarital agreement can adversely affect a child’s right to support (§ 61.079(4)(b)).

We are already married. Can a postnup keep future earnings separate?

A postnuptial agreement can also address future earnings. Disclosure rules are stricter after the wedding: for death-time rights, § 732.702(2) requires each spouse to make fair disclosure when the waiver is signed after marriage, while none is required before. See our Florida postnuptial agreement page.
