A beneficiary designation dispute in Florida often starts with one surprise: a life insurance check or retirement account goes to someone other than the person the family expected.

This page explains which accounts pass by designation, the grounds Florida courts consider, and how a dispute usually moves forward. Leslie V. Marenco is the responsible lawyer for this page.

Why a Beneficiary Designation Can Override a Will in Florida

A beneficiary designation generally decides who receives an account at death. It is a form you file with an insurer, bank, custodian or plan administrator. It names the person or trust that gets the money. The company then pays according to its own records and rules.

Florida law recognizes this for many death benefits. Under § 733.808, life insurance, annuity and health or accident proceeds can be made payable to a trustee.

Why does this matter? Families read a will, see equal shares, and assume the estate will split that way. The insurance check or IRA may go to someone else. Your will or trust still controls assets titled in the trust or left in the probate estate. So the first step is sorting what passes by form and what passes by document. For the broader framework, see our trust litigation attorney page.

If a life insurance payout or retirement account went to someone you did not expect, we can review the forms and timeline with you. Talk it through with Trust Counsel, PL — the first consultation is free, confidential, and carries no obligation.

Which Accounts Pass by Designation: Life Insurance, IRAs and Employer Plans

Fla. Stat. § 732.703 addresses designations that provide for the payment or transfer at death of an interest in life insurance policies, annuities, employee benefit plans, individual retirement accounts, payable-on-death accounts and accounts registered in transfer-on-death form to or for the benefit of the decedent’s former spouse. Florida’s divorce and death-benefit designation rules are set out in Fla. Stat. § 732.703, which applies to the asset types listed in its subsection (3).

The governing paperwork is usually the company’s or plan’s own beneficiary form and plan terms. Each insurer, custodian or employer plan sets its own process for changes, including how a change must be made and recorded.

Records matter for this reason. The most recent valid form on file is usually the one the company follows. An older form, a form never filed, or a lost change request can change the result. Ask the custodian for the full history of every change, not just the current form. Ask for the plan documents too, because they explain how the plan pays out.

Grounds Under Florida Law for Challenging a Will or Trust

Each ground needs its own proof.

Undue influence has its own statutes. Under § 732.5165, a will is void if its execution is procured by fraud, duress, mistake, or undue influence, and this section applies to wills, not to beneficiary designation forms. A trust procured that way is void under § 736.0406. Florida also has a presumption tied to abuse of fiduciary or confidential relationships. Under § 733.107, in any transaction or event to which the presumption of undue influence applies, the presumption implements public policy against abuse of fiduciary or confidential relationships and is a presumption shifting the burden of proof under ss. 90.301-90.304.

Fraud has its own rules. Forgery asks a different question: did the owner actually sign the form? That often turns on handwriting and records.

Each claim turns on its own evidence. A court reviews the specific facts. No lawyer can promise how a judge will rule.

Divorce, Revocation Rules and Employer Plan Limits

Under Fla. Stat. § 732.703, a designation made by or on behalf of the decedent providing for the payment or transfer at death of an interest in an asset to or for the benefit of the decedent’s former spouse is void as of the time the decedent’s marriage was judicially dissolved or declared invalid by court order prior to the decedent’s death, if the designation was made prior to the dissolution or court order. In that case the decedent’s interest in the asset passes as if the former spouse predeceased the decedent, though the statute lists exceptions, such as to the extent that controlling federal law provides otherwise. That applies if the form was made before the order. The owner’s interest then passes as if the former spouse died first.

The statute draws a line for retirement accounts. Under § 732.703, an individual retirement account of the kind described in the Internal Revenue Code, or an employee benefit plan, may not be treated as a trust for purposes of that section. The same statute also says it does not affect the rights and duties of any insurance company, financial institution, trustee, administrator, or other third party, § 732.703.

So the same divorce can produce different results. A policy, an IRA and a 401(k) each follow their own paperwork. Review the plan terms. Don’t assume the divorce answer applies to every account.

Evidence to Gather Before Taking Any Step

Gather the paperwork first, because the timeline comes from the documents. Start with these four groups.

  • Designation forms: every beneficiary form, change request and prior version from the insurer, custodian or plan administrator.
  • Estate documents: the will, trust, powers of attorney and every amendment, in date order.
  • Context records: medical records, letters, emails and account statements from around each change.
  • Dates: the date of each change, the date of death, and any notice the insurer or plan sent.

Write down what you recall about each change while it is fresh. Note who was present, who arranged the paperwork and who had access to the owner. Keep originals in one folder, and don’t alter them. These details help show who was involved and when.

How a Designation Dispute Typically Moves Forward

If that claim stays unresolved, the matter may move to court in Florida. The account type and the facts shape the next step.

Deadlines matter. If no trustee makes proper claim to life insurance or annuity proceeds within six months after death, or satisfactory evidence shows that no trustee will be there to receive them, the insurer shall pay the personal representative of the person who made the designation, unless otherwise provided by agreement with the insurer or obligor during the lifetime of the insured, § 733.808. For a revocable trust, a contest is barred if not started within the earlier of the chapter 95 time or six months after the trustee sends the required notice, § 736.0604. Early review helps preserve your options.

Court is one route. Under § 733.105, when property passes by intestate succession or the will is unclear and there is doubt about who is entitled to any part of the property or about the shares and amounts that any person is entitled to receive, an interested person may petition the court to determine beneficiaries or their shares. Mediation is another route.

Roles matter too. A personal representative is a fiduciary who shall observe the standards of care applicable to trustees, § 733.602. Trust Counsel’s attorneys can serve individually as trustee or personal representative. The firm advises and represents trustees, personal representatives and beneficiaries. For statewide context, see our Florida trust litigation page.
