Disputes Among Heirs and Estate Litigation in Florida: A Probate Attorney’s Guide

Disputes among heirs and estate litigation in Florida refer to the legal conflicts that arise when beneficiaries, heirs, or interested parties disagree over how a deceased person’s estate is administered, who inherits, or whether the will itself is valid. These disputes are resolved through formal proceedings in the Florida probate court, governed by the Florida Probate Code (Chapters 731 through 735, Florida Statutes) and the Florida Probate Rules. In Palm Beach County, that means filing in the Circuit Court’s probate division and, often, litigating questions that the family never imagined when the loved one was still alive.

I have spent years watching estates that should have closed quietly in a few months turn into multi-year battles. The estate is rarely the real issue. The real issue is usually a sibling who felt cut out, a second spouse the children never accepted, or a caregiver who appeared late and left with the house. Florida law gives the court tools to sort these things out — but it helps to understand the terrain before you step onto it.

Why Heir Disputes Happen in Florida Estates

Florida is a magnet for estate conflict, and not by accident. We are a destination for retirees, blended families, and significant wealth that arrives from other states. Add our homestead protections, our large population of elderly residents vulnerable to undue influence, and a steady flow of out-of-state heirs who only learn the details after a death, and you have a recipe for litigation.

Most fights trace back to one of a handful of root causes:

• Unequal treatment of children. One child gets the house or the brokerage account; the others get a fraction. Resentment that simmered for decades boils over at the reading.
• Late-life changes to the estate plan. A will or trust amended months before death — often after a diagnosis — invites suspicion about capacity and influence.
• Second and third marriages. Children from a first marriage and a surviving spouse from a later one rarely share the same interests.
• A personal representative who acts alone. When the executor stops communicating, beneficiaries assume the worst — and sometimes they are right.
• Missing or ambiguous documents. No will, an unsigned draft, or a will that contradicts beneficiary designations on a life insurance policy.

This site focuses heavily on the path from contested guardianship into probate, and for good reason. When an aging parent is placed under guardianship while still alive, the family conflict has already started. The guardianship court has already heard arguments about capacity, undue influence, and who controls the money. When that person dies, those same accusations migrate straight into the probate case — frequently with a sharper edge, because now there is no chance to ask the decedent what they actually wanted.

The Main Categories of Florida Estate Litigation

Will Contests

A will contest is a formal challenge to the validity of a will. Under Florida law, an interested person may object on several grounds: lack of testamentary capacity, undue influence, fraud, duress, mistake, or improper execution. Florida has strict execution requirements — section 732.502, Florida Statutes, requires the testator’s signature at the end, in the presence of two attesting witnesses who also sign in the presence of the testator and each other. A will that fails these formalities can be thrown out no matter how clear the decedent’s intentions were.

Undue influence is the ground I see most often, especially in cases that began as guardianship disputes. Florida courts apply the framework from In re Estate of Carpenter, which allows a presumption of undue influence to arise when a person who benefits substantially under the will occupied a confidential relationship with the decedent and was active in procuring the will. Establishing that presumption shifts the practical burden and changes the entire posture of a case.

Trust Disputes

Many Florida estates are governed by revocable living trusts rather than wills, which moves the fight into the Florida Trust Code (Chapter 736). Trust litigation often centers on the validity of trust amendments, a trustee’s refusal to provide an accounting, or self-dealing. Beneficiaries have a statutory right to information under section 736.0813 — a trustee who stonewalls is handing the beneficiaries a cause of action.

Breach of Fiduciary Duty Claims

The personal representative of an estate and the trustee of a trust are both fiduciaries. They owe duties of loyalty, impartiality, and prudent administration. When a personal representative pays himself excessive fees, sells estate property to a friend below market, favors one beneficiary, or simply loses money through neglect, the remedy is a surcharge action — a request that the court order the fiduciary to repay the estate from their own pocket and, in serious cases, remove them under section 733.504.

Homestead and Spousal Rights Disputes

Florida’s homestead protections are unique and a frequent source of conflict. A homestead generally cannot be devised away from a surviving spouse or minor child, and an improper devise can be void. Separately, a surviving spouse may claim an elective share — 30% of the elective estate under section 732.2065 — even if the will leaves them nothing. Second-marriage families litigate these rights constantly.

Creditor Claims and Accounting Objections

Disputes also arise between the estate and creditors, or among heirs over the personal representative’s final accounting. Florida imposes firm deadlines: creditors generally must file claims within three months of the first publication of the notice to creditors, or within 30 days of being served, under section 733.702. Heirs who object to the accounting must do so within the period set by the probate rules or risk waiving the objection.

How Estate Litigation Actually Moves Through a Palm Beach Court

People imagine a dramatic trial. Most cases never get there. Here is the realistic sequence:

1. Standing and the petition. Only an “interested person” — an heir, beneficiary, or creditor whose interest may be affected — can litigate. The dispute is framed in a petition or a formal objection filed in the probate case.
2. The automatic pause. When a will is challenged, administration of the contested portions effectively stalls while the validity question is resolved.
3. Discovery. This is where cases are won. Depositions of the drafting attorney, the witnesses, the caregiver, and the treating physicians; subpoenas for medical and financial records; review of the decedent’s prior estate plans to show a pattern — or a sudden break from one.
4. Mediation. Florida courts routinely order mediation, and the overwhelming majority of estate disputes settle there. A confidential, structured negotiation often resolves what years of family argument could not.
5. Trial. If mediation fails, the probate judge — not a jury — decides. Will and trust contests in Florida are tried to the bench.

Timelines vary widely. A clean accounting objection might resolve in a few months. A contested will involving capacity, undue influence, and a guardianship backstory can run two to three years and consume a meaningful share of the estate in fees.

The Guardianship-to-Probate Pipeline

Because this firm concentrates on contested guardianship-to-probate transitions, it is worth saying plainly: a guardianship file is a litigation roadmap. If a parent was placed under guardianship in their final years, the court record already contains physician reports on capacity, an examining committee’s findings, accountings of how the guardian spent the ward’s money, and a documented history of who was fighting whom.

When the ward dies, smart litigants mine that record. Was a will or trust amendment signed during the period a court had already found the person incapacitated? If so, that document may be presumptively void. Did the guardian — often a family member — make gifts or transfers to themselves without court approval? That is a surcharge claim waiting to be filed in the estate. The transition from guardianship to probate is not a clean handoff; it is where the unfinished business of the guardianship gets settled.

Practical Steps to Protect Your Position

If you suspect a problem with a Florida estate, the worst thing you can do is wait. Evidence disappears, witnesses’ memories fade, and deadlines run. Concrete steps:

• Demand documents in writing. Ask for the will, any trust, and a full accounting. A fiduciary’s refusal is itself revealing.
• Preserve records. Bank statements, medical records, prior estate-planning documents, and emails or texts showing the decedent’s intentions or the influence of others.
• Mind the clock. Objection periods and creditor deadlines in Florida are short and unforgiving.
• Do not sign a release. Personal representatives sometimes ask beneficiaries to sign waivers before distributing a share — get advice before signing away your rights.
• Talk to a probate litigation attorney early. The first 30 days often determine whether you preserve leverage or lose it.

When to Bring in a Probate Litigation Attorney

Not every disagreement needs a lawsuit. A delayed distribution might just mean the personal representative is waiting on a tax clearance. But certain signals justify an immediate call: a will amended shortly before death, a fiduciary who refuses to account, a homestead being sold out from under a surviving spouse, or a guardianship history full of red flags. In those situations, an experienced attorney can often resolve the matter through a well-aimed demand and mediation — without the cost of a full trial.
