Maine's rule: barred at equal fault

Under 14 M.R.S. § 156, "if such claimant is found by the jury to be equally at fault, the claimant may not recover." This makes Maine a 50% bar state: a claimant whose fault is found to equal 50% is barred entirely, not just a claimant whose fault exceeds 50%. Legislative attempts in recent years to soften this to a true 51% "greater than" standard did not become law — the original equal-fault bar remains in effect.

A genuinely distinctive wrinkle: "just and equitable," not a strict formula

Here's where Maine stands apart from nearly every other state on this site. Rather than directing a strict, mechanical percentage reduction, § 156 tells the jury to reduce damages "to such extent as the jury thinks just and equitable having regard to the claimant's share in the responsibility for the damage." In practice, this gives a Maine jury real discretion in how it applies a claimant's share of fault to the final damages figure, rather than a rigid, dollar-for-dollar percentage cut. Some attorneys describe this as Maine's "informed judgment" approach.

What our estimate assumes

Because an actual Maine jury verdict can reflect more than a pure mathematical formula, the number above is a straightforward proportional estimate, useful as a starting reference point — not a guarantee of how a Maine jury would apply its own judgment to the same facts.

Joint and several liability: still intact in Maine

Unlike a number of states that have abolished or limited joint and several liability among multiple defendants, Maine retains it. This means that when more than one defendant is found liable, a claimant may potentially recover the full judgment from any single defendant, regardless of that defendant's individual share of the fault, leaving it to the defendants to sort out contribution among themselves.

Who decides the percentage

The jury determines fault, and any defendant has the right to request, through special interrogatories, that the jury specify the percentage of fault contributed by each defendant individually — relevant in a case involving more than one at-fault party.

Maine comparative negligence — frequently asked questions

Does Maine use a 50% or 51% bar for comparative negligence?

A 50% bar. Under 14 M.R.S. § 156, a claimant found by the jury to be equally at fault — 50% or more — may not recover at all.

What happens if I'm found exactly 50% at fault in Maine?

You recover nothing. Maine's statute specifically bars recovery when the claimant is found equally at fault, not only when their fault is strictly greater.

Does Maine reduce damages by a strict percentage like most states?

Not exactly. Maine's statute directs the jury to reduce damages "to such extent as the jury thinks just and equitable" given the claimant's share of responsibility, giving juries more discretion than a rigid mathematical formula.

Has Maine abolished joint and several liability among defendants?

No. Maine is one of the states that retains joint and several liability, meaning a claimant may potentially recover the full judgment from any one defendant found liable, regardless of that defendant's individual share of fault.

Who decides the fault percentage in a Maine claim?

The jury, which may be asked through special interrogatories to specify the percentage of fault contributed by each defendant.

This calculator provides an estimate for general guidance only and is not legal advice. Figures are based on Maine statute (14 M.R.S. § 156) verified per our methodology. Because Maine juries have discretion in how they apply a claimant's fault, the actual reduction in a real case may differ from a strict proportional estimate. Confirm how these rules apply to a specific claim with a licensed Maine attorney before acting.
