Family litigation attracts a particular kind of abuse: claims filed to punish rather than win, defenses maintained long after the facts collapse, motions designed to burn the other side’s money. Florida’s answer is § 57.105 — a sanctions statute with a distinctive feature that makes it the most usable deterrent in civil practice: the 21-day safe harbor letter, which forces an opponent to either abandon a frivolous position or own the fee exposure for keeping it. Wielded correctly, it changes behavior without a hearing; wielded carelessly, it sanctions the sender. The Law Office of John Vernon Moore, P.A. brings over 89 years of combined experience to litigation discipline — imposing it and defending against its misuse — in Brevard County family courts.
What § 57.105 Sanctions Punish
The statute authorizes fee awards against a party and their attorney (splitting the award between them) when they knew or should have known that a claim or defense: (a) was not supported by the material facts necessary to establish it, or (b) was not supported by then-existing law as applied to those facts — without a good-faith argument for changing the law. It also reaches litigation conduct taken primarily for delay. Translated to family practice, the recurring targets: the alimony claim maintained after documents proved the claimed need false; the paternity defense pressed after DNA results; the serial contempt motions filed on obligations already paid; the imputation argument contradicted by the movant’s own records; and boilerplate defenses that discovery long ago hollowed out. What the statute does not punish: losing. Weak-but-colorable positions, credibility contests, and good-faith extensions of law are litigation — the statute targets positions no informed lawyer could maintain.
The Safe Harbor: The 21-Day Letter That Does the Work
The mechanism is the genius of the statute. A party seeking sanctions must first serve the motion on the opponent — without filing it — and wait 21 days. If the offending claim or defense is withdrawn or corrected within the window, no sanctions; if it is maintained, the motion may be filed, and exposure runs from the position’s inception. The consequences ripple through practice: the safe-harbor letter is a formal, documented warning that forces opposing counsel to independently evaluate their client’s position (their own wallet now being on the line — the attorney shares the sanction unless they acted on the client’s misrepresentations); it creates a decision point that frequently ends the frivolous position quietly; and it builds a record that colors every later fee argument under the Rosen conduct doctrine covered on our attorney’s fees page. Courts can also raise § 57.105 on their own initiative — no safe harbor required — which keeps the deterrent alive even where no letter was sent.
Using It Well — and Not Getting Burned
The statute is symmetrical: a § 57.105 motion that is itself frivolous invites sanctions against the sender, and courts have little patience for the letter deployed as routine intimidation. The discipline we apply before any safe-harbor service: the target position must be specifically identified — claim by claim, not the-whole-case-is-frivolous; the factual or legal void must be documentable (the DNA result, the payment records, the controlling case) rather than argumentative; and the letter must be precise enough that a court later reads it as a genuine warning, not posturing. Timing matters too: served too early, the letter attacks positions discovery has not yet tested; served after the evidence lands, it is nearly unanswerable. In family cases the highest-value deployments cluster around enforcement abuse (motions on paid obligations), positions contradicted by the movant’s own sworn filings, and the delay tactics — serial continuances, reflexive objections — that the statute’s delay prong reaches directly.
Defending Against a 57.105 Motion
Receiving a safe-harbor letter demands sober triage, not reflexive defiance. The 21 days are for exactly one exercise: an honest merits audit of the challenged position — what evidence supports each element, what law sustains it, and whether either has eroded since filing. If the position fails the audit, withdrawal within the window costs nothing and ends the exposure; if it holds, the response is a documented record of the supporting facts and authority, which both defeats the eventual motion and shifts the frivolousness question back onto the sender. The defenses that work at hearing: the position was supported by material facts (produced and cited); the legal argument was a good-faith extension; the attorney reasonably relied on the client’s representations (which protects counsel, though not the client); and the safe harbor itself was defective — unserved, premature, or aimed at conduct outside the statute. What fails: indignation, volume, and the argument that everything filed in good anger is filed in good faith. With over 89 years of combined experience, our team audits positions honestly in both directions — which is why our letters get results and our clients rarely receive ones that stick.
What does a 57.105 sanction actually cost the losing side?
The reasonable attorney’s fees the frivolous position caused — from its inception, not just after the letter — split equally between the offending party and their counsel unless the attorney relied on the client’s misrepresentations. In a heavily litigated family case, that number reaches five figures with unpleasant speed.
I received a safe-harbor letter. Should I withdraw my claim?
Treat it as a forced second opinion: have counsel audit the claim’s evidence and law within the window. Withdraw what cannot be defended — free inside 21 days, expensive after — and paper what can. The one indefensible response is ignoring it.
Can I send a 57.105 letter myself, without a lawyer?
The statute applies to self-represented parties, but the letter is a precision instrument: misaimed, it creates your own exposure and hands the other side a conduct exhibit. This is one of the clearest spend-a-little-to-avoid-a-lot moments in family practice.
Does 57.105 apply to my ex constantly dragging me back to court?
Repetitive, baseless post-judgment motions are squarely in the statute’s lane — especially enforcement motions on satisfied obligations and modification attempts pleading nothing new. A safe-harbor letter, a fee record, and where the pattern persists, vexatious-litigation relief form the escalation ladder.
