Undue Influence in Florida Will Contests: The Carpenter Factors and the Burden-Shifting Presumption

When a parent's will suddenly disinherits lifelong beneficiaries in favor of a caregiver, a new spouse, or one sibling who controlled every doctor's appointment and bank account, Florida law does not simply shrug. Under Section 732.5165, Florida Statutes, a will procured by fraud, duress, mistake, or undue influence is void — either in its entirety or as to the tainted portion. But proving undue influence is uniquely difficult, because the one person who could best describe what happened — the decedent — is gone, and the influencer rarely exerts pressure in front of witnesses.

Florida's answer to that evidentiary problem is a powerful burden-shifting presumption, built on the Florida Supreme Court's landmark decision in In re Estate of Carpenter, 253 So. 2d 697 (Fla. 1971), and later strengthened by the Legislature in Section 733.107(2), Florida Statutes. For families litigating estates in the Probate Division of the Eleventh Judicial Circuit in Miami-Dade County, understanding how the Carpenter factors trigger that presumption — and what happens once it attaches — is often the difference between winning and losing a will contest.

What Is Undue Influence Under Florida Law?

Undue influence is more than persuasion, nagging, or ordinary family lobbying. Florida courts define it as over-persuasion, duress, force, coercion, or artful or fraudulent contrivances to such a degree that the testator's free agency and willpower are destroyed — so that the will expresses the influencer's wishes rather than the decedent's. The influence must amount, in effect, to a form of mental coercion.

Two points follow from that definition:

• Motive and opportunity alone are not enough. A child who lived with an elderly parent and stood to inherit is not automatically an undue influencer. The contestant must show the influence was actually exercised and directed at procuring the will.
• A will can be partially void. Section 732.5165 allows the court to strike only the provision procured by undue influence — for example, a single devise to the influencer — while leaving the rest of the will intact.

Undue influence claims frequently overlap with lack of testamentary capacity, but they are distinct theories. A testator can be fully competent and still be unduly influenced; indeed, the presumption discussed below exists precisely because a coerced but competent testator leaves few obvious traces. Undue influence is one of several recognized grounds in Florida will contests, alongside improper execution, incapacity, fraud, and forgery.

The Carpenter Presumption: Three Elements That Shift the Burden

In In re Estate of Carpenter, the Florida Supreme Court held that a presumption of undue influence arises when the contestant proves three elements:

1. The alleged influencer is a substantial beneficiary under the will;
2. The influencer occupied a confidential relationship with the decedent; and
3. The influencer was active in procuring the contested will.

Each element deserves careful attention, because probate judges in Miami-Dade scrutinize them individually.

1. Substantial Beneficiary

The influencer must receive a meaningful benefit under the challenged instrument. This is usually straightforward: a devise of the homestead, a large percentage of the residuary estate, or a bequest dramatically larger than what the person would have received under a prior will or under Florida's intestacy statutes (Sections 732.101–732.111). Florida courts have also applied the presumption where the benefit flows to someone closely aligned with the influencer, such as the influencer's spouse or child.

2. Confidential Relationship

A confidential relationship exists wherever the decedent placed trust and confidence in the alleged influencer and relied on that person. Florida construes this element broadly. It includes formal fiduciary relationships — an agent under a durable power of attorney (Chapter 709, Florida Statutes), a trustee, a guardian — but also informal relationships: an adult child who managed the parent's finances, a caregiver who controlled access to the decedent, a companion who handled banking, medications, and appointments. In practice, in an aging community like Miami-Dade, this element is often the easiest of the three to establish.

3. Active Procurement — Where the Carpenter Factors Come In

Active procurement is where most cases are won or lost. Because direct evidence of procurement is rare, the Carpenter court identified seven non-exclusive factors that courts use as circumstantial indicators that the beneficiary actively procured the will.

The Seven Carpenter Factors

The Florida Supreme Court listed these criteria for determining active procurement:

1. Presence of the beneficiary at the execution of the will. Was the influencer in the room — or hovering outside the door — when the decedent signed?
2. Presence of the beneficiary when the testator expressed a desire to make a will. Did the idea of a new will surface only in the influencer's presence?
3. The beneficiary recommended the attorney who drafted the will. A new will prepared by the influencer's own lawyer, rather than the decedent's longtime counsel, is a classic red flag.
4. The beneficiary knew the contents of the will before execution. Legitimate beneficiaries usually learn what a will says after death, not before signing.
5. The beneficiary gave instructions to the drafting attorney. Emails, phone logs, or the attorney's file notes showing the beneficiary — not the testator — communicated the dispositive terms are among the most damaging pieces of evidence in these cases.
6. The beneficiary secured the witnesses to the will. Did the influencer round up friends, employees, or neighbors to serve as attesting witnesses required by Florida's execution formalities under Section 732.502? (See our overview of Florida will requirements.)
7. The beneficiary kept the will after execution. Possession and control of the original document suggests control over the process that produced it.

Three practical rules govern how Miami probate judges apply these factors:

• The list is not exclusive. Courts routinely consider additional badges of procurement: isolating the decedent from family, secrecy surrounding the new will, a dramatic and unexplained departure from a long-standing estate plan, the decedent's physical or cognitive frailty, and the influencer's control over mail, phones, and visitors.
• No magic number is required. The contestant does not need all seven factors. Florida appellate courts, including the Third District Court of Appeal (whose decisions bind Miami-Dade probate courts), have found active procurement on fewer factors when they are weighty, and have rejected claims where several factors were present but trivial.
• The factors are evaluated holistically. The question is whether, taken together, the circumstances show the beneficiary played an active role in bringing the will into existence.

The Burden-Shifting Presumption: Section 733.107(2), Florida Statutes

What happens once the contestant establishes all three Carpenter elements is where Florida law has real teeth — and where the law changed significantly after Carpenter itself.

The Baseline Burden of Proof

Section 733.107(1), Florida Statutes, sets the default allocation: in a will contest, the proponent of the will bears the initial burden of establishing prima facie its formal execution and attestation (typically satisfied by a self-proving affidavit under Section 732.503). The burden then shifts to the contestant to establish the grounds for invalidity — including undue influence.

What the Presumption Does

Under the original Carpenter decision, the presumption of undue influence was treated as a mere "vanishing" presumption: once the will's proponent came forward with a reasonable explanation for their role, the presumption disappeared and the contestant still carried the full burden.

The Florida Legislature changed that in 2002. Section 733.107(2) now provides: "The presumption of undue influence implements public policy against abuse of fiduciary or confidential relationships and is therefore a presumption shifting the burden of proof under ss. 90.301–90.304."

The practical consequence, confirmed by Florida appellate decisions applying the amended statute, is dramatic. Once the contestant proves (1) substantial benefit, (2) confidential relationship, and (3) active procurement under the Carpenter factors:

• The presumption does not vanish when the proponent offers an innocent explanation;
• The burden of proof itself shifts to the will's proponent, who must then prove by the greater weight of the evidence that the will was not the product of undue influence; and
• If the evidence is in equipoise — if the judge simply cannot tell — the contestant wins, because the proponent now bears the risk of non-persuasion.

A Worked Example

Suppose a Miami decedent's 2018 will divided her estate equally among her three children. In 2023, months before her death and while suffering from advancing dementia, she signed a new will leaving 90% of her estate to one daughter — the same daughter who held her power of attorney, drove her to a lawyer the daughter selected, emailed that lawyer the dispositive terms, sat in the signing conference, and took the original will home. The other two siblings contest.

Here, the daughter is a substantial beneficiary; the power of attorney and caregiving role establish a confidential relationship; and at least four Carpenter factors (recommending counsel, instructing counsel, presence at execution, possession of the will) establish active procurement. The presumption attaches, and under Section 733.107(2) the daughter must now affirmatively prove the absence of undue influence — for example, through the drafting attorney's testimony of private, unprompted consultations with the mother, contemporaneous medical evidence of clear thinking, and a credible independent reason for the changed plan. If she cannot carry that burden, the 2023 will is set aside and the 2018 will (or intestacy) controls.

Deadlines and Procedure for Raising Undue Influence in Miami-Dade Probate

Undue influence claims are governed by strict, unforgiving deadlines under the Florida Probate Code and the Florida Probate Rules. Miami will contests are filed as adversary proceedings under Florida Probate Rule 5.025 in the Probate Division of the Eleventh Judicial Circuit.

Before the Will Is Admitted: Caveats and Formal Notice

• Caveat by an interested person — Section 731.110, Florida Statutes. If you anticipate a bad will, you may file a caveat with the clerk. Once a caveat is filed, the court may not admit the will to probate or appoint a personal representative until formal notice is served on the caveator, guaranteeing you a chance to object before letters issue.
• Formal notice before probate — Section 733.2123, Florida Statutes. A petitioner may serve formal notice of the probate petition on interested persons before the will is admitted. This is a trap for the unwary: anyone served under this section who does not object may not later challenge the will's validity. Under Florida Probate Rule 5.040(a)(1), a written response is generally due within 20 days after service of formal notice.

After the Will Is Admitted: The 90-Day (or 3-Month) Bar

Once a will is admitted to probate, the personal representative must serve a Notice of Administration under Section 733.212, Florida Statutes. Under Section 733.212(3), any objection challenging the validity of the will, the venue, or the court's jurisdiction is forever barred unless filed within 3 months after service of the Notice of Administration — commonly described as the 90-day deadline. Section 733.109 governs the resulting petition for revocation of probate, which may be filed any time before discharge of the personal representative, but only by an interested person who has not been barred by the notice deadlines.

Worked example: The personal representative serves the Notice of Administration on a disinherited son on March 3. His petition for revocation of probate alleging undue influence must be filed on or before June 3. If he waits until July, his claim is barred no matter how compelling his Carpenter evidence — even proof that his sister dictated every word of the will to the lawyer will not resurrect a time-barred contest. And a will contest can never be filed after the personal representative is discharged and the estate closed.

Because of these compressed timelines, families who suspect undue influence should act immediately upon a death — ideally before probate opens. Our step-by-step guide to how to contest a will in Florida walks through the sequence in detail.

Who May Contest

Only an "interested person" — defined in Section 731.201(23), Florida Statutes, as one who may reasonably be expected to be affected by the outcome — has standing. This typically means beneficiaries under a prior will, intestate heirs (spouse, children, and other relatives under Sections 732.102–732.103), and beneficiaries whose shares were reduced by the contested instrument. Notably, Section 732.518 makes pre-death will contests impossible: a will cannot be challenged until the testator has died.

Building the Evidence: How These Cases Are Actually Proven

Because the presumption turns on circumstantial proof, disciplined discovery is essential. In Miami undue influence litigation, key sources include:

• The drafting attorney's file — intake notes, emails, and billing records showing who contacted the lawyer, who paid, and who supplied the terms (Carpenter factors 3, 4, and 5);
• Medical and pharmacy records documenting cognitive decline, dependence, and susceptibility;
• Financial records — power-of-attorney transactions, changed beneficiary designations, joint accounts, and transfers that mirror the will's scheme;
• Witness testimony from neighbors, caregivers, clergy, and family about isolation, gatekeeping, and the decedent's statements;
• Phone, text, and visitor records showing who controlled access to the decedent in the months before execution.

Note that Section 733.107 applies in contests over wills, but Florida courts apply the same Carpenter framework to revocable trusts, deeds, and beneficiary designations procured by undue influence — important in Miami estates where condominiums, brokerage accounts, and trust-held real estate often pass outside probate.

Defending Against an Undue Influence Claim

The presumption is powerful, but it is not a verdict. Proponents defeat these claims by showing independent legal advice given to the testator alone; long-standing, consistent estate plans that the new will merely refined; documented reasons for disinheritance (estrangement, prior gifts, misconduct); and credible testimony that the testator was strong-willed and made her own decisions. Because Section 733.107(2) places the ultimate burden on the proponent once the presumption attaches, proponents must build this affirmative record early — not simply poke holes in the contestant's case.

Attorney's Fees and Strategic Considerations

Under Section 733.106(1), Florida Statutes, a party who offers a will in good faith may be awarded fees from the estate even if the will is ultimately denied probate, and Section 733.106(4) permits the court to direct from which part of the estate fees are paid — including assessing them against a bad-faith litigant's share. Fee exposure, the strength of the Carpenter factors, and the size of the estate all shape whether a case should be litigated to trial or resolved through mediation, which the Eleventh Judicial Circuit routinely orders in contested probate matters.
