Damages Allocation Guide for American Samoa — Comparative Fault Rules

What this calculator does

Run this scenario in DocketMath using the Damages Allocation calculator.

DocketMath’s damages-allocation tool helps you allocate total damages between liable parties using American Samoa’s comparative fault rule—specifically the modified comparative framework reflected in A.S.C.A. § 43.5101, commonly understood as follows:

• Damages are reduced in proportion to the claimant’s percentage of fault.
• Recovery is barred when the claimant’s fault is 50% or more.

In other words, the calculator is designed for disputes where two or more parties may be negligent (or otherwise at fault) and the factfinder has assigned fault percentages. You provide those percentages and the tool produces:

• Claimant’s recoverable percentage (0% to 100%)
• Claimant’s share of fault
• Defendant(s)’ shares as applicable
• Allocated dollar amounts based on a total damages figure you enter

When to use it

Use the DocketMath damages allocation calculator when the case involves comparative fault issues in American Samoa, such as:

• A negligence action where evidence supports multiple causes of harm
• Multi-party collisions (e.g., traffic incident with driver and roadway conditions, or passenger distraction issues)
• Premises liability scenarios where both plaintiff behavior and defendant conduct contributed to the harm
• Any claim where the fact pattern supports fault apportionment rather than an all-or-nothing liability model

Situations where the tool is most helpful

Check the boxes below when your scenario matches the tool’s assumptions:

Situations where the tool may not fit well

The tool is less suitable if:

• Fault percentages are not part of the analysis (e.g., certain strict liability setups where comparative fault treatment differs)
• Damages aren’t reasonably entered as a single “total” for the allocation step
• You’re dealing with legal doctrines that can cap or reshape damages in ways not captured by a pure percentage split (the calculator focuses on comparative-fault allocation)

Step-by-step example

Below is a full walkthrough using a common comparative-fault structure: one claimant and two defendants. The key decision point is whether the claimant’s fault is below 50% (recovery possible) or 50% or more (recovery barred under A.S.C.A. § 43.5101 as commonly applied).

Assumptions for the example

• Total damages (before fault allocation): $200,000
• Fault allocation:

  • Claimant: 35%
  • Defendant A: 45%
  • Defendant B: 20%

Step 1 — Enter the claimant’s fault percentage

• Claimant fault: 35%

Because 35% < 50%, the claimant is eligible to recover under the modified comparative fault approach.

Step 2 — Enter the total damages

• Total damages: $200,000

Step 3 — Enter defendants’ fault percentages

• Defendant A: 45%
• Defendant B: 20%

The calculator then computes the total fault attributable to defendants:

• Defendant fault total = 45% + 20% = 65%

Step 4 — Determine the claimant’s recoverable “net” percentage

Under comparative fault reduction:

• Claimant recoverable share = 1 − claimant fault
• 1 − 0.35 = 0.65 → 65% recoverable

So claimant recoverable damages:

• $200,000 × 65% = $130,000

Step 5 — Allocate the recoverable amount among defendants (pro rata)

Because defendants are collectively responsible for 65% of fault, the tool distributes the recoverable $130,000 based on the defendants’ proportions of defendant fault:

• Defendant A’s share of defendant fault = 45% / 65% = 0.692307...
• Defendant B’s share of defendant fault = 20% / 65% = 0.307692...

Allocated amounts:

• Defendant A pays: $130,000 × 45/65 = $90,000
• Defendant B pays: $130,000 × 20/65 = $40,000

Step 6 — Summary of outputs

Common scenarios

Comparative fault issues show up in predictable patterns. Here are several scenario templates and how the damages allocation changes with the claimant’s fault threshold under A.S.C.A. § 43.5101.

Scenario 1 — Claimant under 50% fault (recovery reduced)

• Total damages: $80,000
• Fault:

  • Claimant: 49%
  • Defendant: 51%

Result:

• Claimant recoverable = 1 − 0.49 = 51%
• Claimant damages = $80,000 × 51% = $40,800
• Defendant allocation (only defendant) = $40,800

Scenario 2 — Claimant at or above 50% fault (recovery barred)

• Total damages: $80,000
• Fault:

  • Claimant: 50%
  • Defendant: 50%

Result:

• Claimant recovery = $0
• Defendant allocation = $0 (because the claimant cannot recover under the modified comparative fault rule)

A more extreme example:

• Claimant: 70%
• Defendant: 30%
• Output similarly results in $0 recoverable.

Scenario 3 — Multiple defendants (pro rata distribution among defendants)

• Total damages: $300,000
• Fault:

  • Claimant: 25%
  • Defendant A: 60%
  • Defendant B: 15%

Compute:

• Recoverable share = 1 − 0.25 = 75%
• Recoverable damages = $300,000 × 75% = $225,000
• Defendant fault total = 60% + 15% = 75%

Pro rata:

• Defendant A = 60/75 = 0.8 → $180,000
• Defendant B = 15/75 = 0.2 → $45,000

Scenario 4 — One defendant, partial fault split

• Total damages: $120,000
• Fault:

  • Claimant: 10%
  • Defendant: 90%

Result:

• Recoverable = 90% → $108,000
• Defendant allocation = $108,000

Scenario 5 — Reconciling “fault totals” that don’t add to 100%

Fault percentages in real life can be offered in ranges, estimates, or contested. The calculator assumes a coherent allocation. Common approaches:

• If inputs are meant to sum to 100%, enter them as such.
• If you have evidence supporting “fault totals” that don’t precisely sum to 100, you should decide how to normalize before using the tool so your allocation doesn’t misstate relative responsibility.

Tips for accuracy

To get results you can actually use, focus on inputs and the fault cutoff logic under A.S.C.A. § 43.5101.

1) Treat the claimant’s percentage as the “switch”

The calculator’s recovery turns on whether the claimant is:

• < 50% fault → recovery reduced but possible
• ≥ 50% fault → recovery barred

If your claimant percentage estimate is, say, 49.9% vs 50.1%, the outputs can change from “recover” to “recover nothing.” Consider running two versions:

• One with the claimant at the low-end estimate
• One at the high-end estimate

2) Keep total damages consistent across runs

When modeling settlement ranges:

• Hold total damages constant across comparative-fault runs when you’re only testing fault allocation sensitivity.
• Change only one variable at a time (e.g., claimant fault) to understand what’s driving the delta.

3) Use a clean fault structure (claimant + all defendants)

To prevent allocation confusion:

• Include every party you want reflected in the pro rata defendant distribution.
• If you omit a defendant, their fault effectively disappears from the defendant pool, which can distort how the tool divides recoverable damages among remaining defendants.

4) Use rounding strategically

Fault percentages often come with rounding. Example:

• Claimant: 33.3%
• Defendant A: 33.4%
• Defendant B: 33.3%

You might round to one decimal place or whole numbers. The tool will reflect the rounded model. If your results are close to the cutoff, prefer the finer-grained figures you have.

5) Validate the internal arithmetic
