A Licznerski Law, PLLC Educational Series: Understanding Personal Injury Case Value
One of the first questions we hear from potential clients is simple: “What is my case worth?” It’s a fair question — and an important one. But the answer depends almost entirely on one thing that most people never think about until after an accident: insurance coverage.
This post continues our series on personal injury case value in Florida. These are educational hypotheticals — not a guarantee of any outcome, including yours. Every case is different, and the only way to understand what your specific situation is worth is to speak with an attorney.
Throughout this series, we’ve talked about UM coverage as the single most important protection a Florida driver can buy. But there’s a feature of UM coverage that most people have never heard of — and it can dramatically change what your policy is actually worth to you. It’s called stacking, and it’s the subject of this post.
What Is Stacked UM Coverage?
In Florida, when you purchase UM coverage, your insurer is required to offer you the option to “stack” that coverage — unless you affirmatively reject stacking in writing. Stacking means that if you own multiple vehicles insured under the same policy, your UM limits multiply by the number of vehicles covered, rather than being capped at a single per-accident limit.
Here’s a simple example: if you carry $100,000 in UM coverage and insure three vehicles on your policy, stacked UM coverage means you potentially have access to $300,000 in UM benefits — three times your stated limit — for a single accident, even though you were only driving one of those three vehicles at the time.
Non-stacked UM, by contrast, limits you to the single stated policy limit no matter how many vehicles you insure. $100,000 non-stacked means $100,000 available, period — regardless of how many cars are on the policy.
This distinction is governed by Florida Statute § 627.727, and it is one of the most commonly misunderstood — and most consequential — coverage decisions a Florida driver makes, often without realizing they made it at all.
The Scenario: $10,000 PIP, $100,000 BI, $100,000 UM Stacked Across Three Vehicles
Here’s the situation:
- You were injured in a car accident that was someone else’s fault.
- Your own auto policy includes $10,000 PIP and $100,000 in UM coverage, with stacking elected.
- You insure three vehicles under that policy.
- The at-fault driver has a $100,000 BI policy.
On paper, this looks identical to a scenario we’ve already covered in this series — $100,000 BI and $100,000 UM. But because the UM coverage is stacked across three vehicles, the actual available UM coverage is not $100,000. It’s $300,000.
How Stacking Changes the Math
PIP — $10,000
Functions exactly as it does in every scenario we’ve discussed: pays providers directly, covers 80% of medical and 60% of lost wages up to the limit, and is not money that reaches the client’s pocket except for any lost wages portion.
At-Fault Driver’s BI — $100,000
This works exactly as described in our earlier post covering this same BI limit. The BI carrier’s exposure does not change based on your own coverage — it remains capped at $100,000 regardless of what you carry on your own policy.
UM Coverage — $300,000 (Stacked)
This is where stacking transforms the case. Instead of a $100,000 UM ceiling, the client has access to up to $300,000 in UM benefits. If the BI carrier pays its full $100,000 limit and the client’s total damages are valued at, say, $350,000, the UM carrier is potentially responsible for the remaining $250,000 — well within the stacked $300,000 limit, whereas a non-stacked policy would have left $150,000 of that gap completely uncovered.
In effect, stacking on a three-vehicle policy can triple the total coverage available to an injured client without the client paying three times the premium. Stacked coverage typically costs more than non-stacked coverage, but nowhere near a proportional multiple — making it one of the best value propositions in all of auto insurance.
Why So Many Floridians Don’t Have It
If stacked UM coverage is this valuable, why doesn’t everyone have it? Two reasons, mostly.
First, stacked coverage costs more than non-stacked coverage, and many drivers — or the insurance agents selling them policies — default to the cheaper option to keep monthly premiums low, without fully explaining what’s being given up.
Second, and more significantly: Florida law requires insurers to obtain a written waiver if a policyholder rejects stacked coverage. In practice, many drivers sign this waiver during the application process without understanding what it means — sometimes bundled into a stack of other insurance paperwork being signed in a matter of minutes. The form is legally sufficient, but the informed decision-making behind it is often missing.
This is why one of the first things we examine in any case is the client’s own declarations page and policy documents — to determine not just whether UM coverage exists, but whether it’s stacked, and whether the rejection of stacking (if any) was executed properly. An improperly executed stacking waiver can sometimes be challenged, potentially restoring stacked coverage that the carrier claims doesn’t exist.
What Does This Mean for Case Value?
The case value itself is still driven by the damages — the injury, the treatment, the impact on the client’s life. What stacking does is widen the funnel through which those damages can actually be compensated.
A few ways this plays out in practice:
A household with two or three vehicles and modest UM limits can end up with effective UM coverage that rivals or exceeds a household that bought higher per-vehicle limits but declined to stack. A $50,000 stacked UM policy across four vehicles provides up to $200,000 in coverage — more than a $100,000 non-stacked policy, at a fraction of the premium difference.
Stacking becomes especially significant in moderate-to-serious injury cases where damages fall in a range that a single UM limit can’t fully cover, but a stacked limit can. This is precisely the gap where many injured clients with non-stacked policies are left undercompensated, simply because of a form they signed years before the accident and may not even remember.
It’s also worth noting: stacking applies to the at-fault driver’s coverage too, in certain circumstances involving resident relatives and household policies, though that analysis is more complex and fact-specific.
The Lesson for Every Florida Driver
If you own more than one vehicle, ask your insurance agent directly whether your UM coverage is stacked — and if you’ve been told you waived stacking, ask to see the form and understand exactly what you signed. The cost difference is often smaller than people assume, and the protection it provides, as this post illustrates, can be the difference between a case that’s fully compensated and one that isn’t.
If you’ve already been in an accident and you’re not sure whether your policy includes stacked coverage, that’s something an attorney should review before any claim is finalized — not after.
This Is Educational, Not Legal Advice
Every personal injury case is different. The scenario above is a hypothetical designed to help you understand how insurance coverage shapes recovery options in Florida. Nothing in this blog series should be taken as a prediction or guarantee of results in any specific case, including yours.
