Finding out that a sibling, cousin, or another heir is contesting the will you were named in changes the entire probate experience overnight. One day you are waiting on an estate to close. The next, you suddenly become part of a legal dispute you never expected.
A co-beneficiary dispute puts you in an unusual position. You are not the one contesting anything, but the outcome of someone else's challenge determines what you actually receive. Challenging a will in Florida follows a specific legal process, and understanding what that process actually involves is the first step toward responding well instead of just reacting.
Grounds for Contesting a Will in Florida

Florida law recognizes four principal grounds for challenging a will's validity. Knowing which one is being alleged shapes everything about how the dispute will unfold.
- Lack of testamentary capacity, meaning the person did not understand what they were signing or what their assets consisted of at the time
- Undue influence, meaning someone improperly pressured or manipulated the person into signing a will that reflected the influencer's wishes rather than their own
- Fraud, meaning the person was deceived about the document's content or purpose
- Improper execution, meaning the will was not signed or witnessed according to Florida's specific legal formalities
Undue influence claims carry a particular legal mechanism worth understanding if you are defending a will you benefit from. A contestant can show three things: a beneficiary received a substantial share, held a confidential relationship with the deceased, and was actively involved in procuring the will. Once those three elements are shown, Florida law shifts the burden to the will's defenders. The burden shifts to those defending the will to rebut the presumption of undue influence.
What a Co-Beneficiary Dispute Actually Triggers

A will contest is not an informal disagreement worked out at a family dinner. It is a formal legal filing with a strict deadline attached. Once the personal representative serves a Notice of Administration, the clock starts. Any interested person, including the one now contesting the will, generally has three months to file a formal objection.
That same deadline applies to every interested person. If you are a co-beneficiary who also has concerns about how the will was prepared, that same three-month window applies to you too. Missing it can bar you from raising those concerns later, even if they are legitimate. A Florida will dispute that surfaces after that window closes faces a much steeper procedural climb, regardless of which side of it you are on.
The Personal Representative's Role
The personal representative occupies an unusual position once a dispute arises. If they were named in the will being challenged, they generally have a duty to defend its validity using estate assets. Their authority to act comes directly from that document.
At the same time, the personal representative cannot simply distribute contested assets while the challenge is pending. Estate assets typically stay frozen in relevant part until the dispute resolves, which means every beneficiary, contesting or not, waits during that period. A personal representative who distributes assets prematurely, before a contest is resolved, can face personal liability if the will is later found invalid.
Why No-Contest Clauses Don't Work in Florida
Some wills include a clause stating that any beneficiary who contests the will forfeits their inheritance entirely. These are sometimes called in terrorem clauses, and they exist specifically to discourage exactly this kind of dispute.
Here is something worth knowing if a will you are involved with includes one: Florida Statute 732.517 makes these clauses unenforceable. A court simply disregards the penalty language and treats the challenge on its merits, as though the clause were never written. Florida is among the minority of states that refuse to enforce no-contest clauses. Most states enforce no-contest clauses with some exceptions, but Florida voids them outright. A beneficiary weighing whether to raise legitimate concerns about a will does not have to weigh that decision against an automatic forfeiture threat.
What the Will Dispute Timeline Looks Like

A standard Florida probate already runs nine months to two years for formal administration. A contested will adds meaningfully to that baseline, and the added time depends heavily on how the dispute resolves.
- Filing and initial pleadings typically take a few months from the notice of administration through the objection deadline
- Discovery, gathering medical records, deposing witnesses, reviewing the drafting attorney's file, often takes six months to a year in a genuinely contested case
- Mediation frequently happens before trial, since Florida probate courts commonly require or strongly encourage it
- A case that proceeds to trial, rather than settling, can add another year or more before final resolution
Most will contests in Florida resolve through settlement rather than trial. Litigation costs and the uncertainty of trial outcomes push both sides toward a negotiated resolution somewhere in the middle.
When to Settle vs. Defend a Will Dispute
The decision to settle or fight a contest usually comes down to a handful of practical factors. It is rarely just about how strongly you feel the will reflects the deceased's true wishes.
The strength of the evidence matters most. A contest built on vague suspicion tends to lose steam once discovery begins. A contest supported by contemporaneous medical records documenting cognitive decline, or a drafting attorney's file showing red flags at the time of signing, carries real weight. The size of the estate relative to litigation costs matters too. Contesting or defending a modest estate through a full trial can consume a meaningful share of what is actually being fought over. That is part of why how to resolve a will dispute so often comes down to a cost-benefit calculation rather than pure principle.
Family dynamics factor in as well, whether fairly or not. Some families can absorb a contested will and still function afterward. Others cannot, and that reality sometimes weighs as heavily as the legal merits when co-beneficiaries decide how hard to push back.

Responding to a Will Dispute as a Co-Beneficiary
Being named in a will that someone else is now contesting puts you in a position most people never expect to be in. You did not initiate anything. Yet the outcome shapes what you actually inherit, how long the estate stays open, and how the family functions once it is finally settled.
The strongest response usually starts with understanding exactly what ground the contest is built on. Beneficiary disputes over inheritance built on capacity look nothing like those built on undue influence, whether in terms of evidence, timeline, or likely outcome. From there, the decision between settling and defending becomes a much clearer, more practical calculation instead of an emotional one made under pressure.
If you have been named in a Florida will that is now being challenged by another heir, talk with a Florida probate attorney. Getting legal advice early can help you understand your options before responding to the contest or communicating with the opposing party's attorney.
