Litigation > Damages and Remedies | Published 26 July 2024 - Updated 18 November 2024 | UpLaw - uplaw.us

How to Use This Checklist

Phase 1 runs in the first week. Phases 2 through 5 run through discovery. Phases 6 and 7 run before trial. Phases 8 and 9 follow.

The doctrine is in damages and remedies. The narrative orientation is putting a number on the harm. The worksheets are in the damages proof and remedies toolkit.

Phase 1 — Screening and Valuation

☐ List every damages category the facts support, by claim.

☐ For each category, name the document that proves it, and confirm today that the document exists.

☐ Screen for statutory theories before building any actual-damages model. Check for statutory damages such as 17 U.S.C. § 504, 15 U.S.C. § 1692k, 15 U.S.C. § 1681n, and 15 U.S.C. § 1681o; multipliers such as 15 U.S.C. § 15, 15 U.S.C. § 1117, 18 U.S.C. § 1836, and 29 U.S.C. § 216; and caps such as 42 U.S.C. § 1981a with back pay under 42 U.S.C. § 2000e-5.

☐ Check fee entitlement — contract, or a statute such as 42 U.S.C. § 1988 or 17 U.S.C. § 505. Costs follow Rule 54.

☐ Check contractual limitations — liability caps, consequential damages waivers, liquidated damages clauses — before valuing anything.

☐ Assess collectibility now. Identify insurance policies, limits, whether defense costs erode limits, and any coverage dispute. Identify visible assets and prior transfers.

☐ Compute the case value from six inputs: provable compensatory damages; statutory overlay; liability probability; cost to judgment; collection probability; and time.

☐ Tell the client the range and the assumptions, in writing.

☐ Decide whether the case is worth bringing on this analysis rather than on the liability facts alone.

Phase 2 — Preservation and Collection

☐ Issue a litigation hold immediately and suspend automatic deletion. See issuing a litigation hold and preserving ESI.

☐ Identify the custodians who hold damages evidence — accounting, sales, operations, human resources.

☐ Collect the plaintiff's records: contracts, invoices, purchase orders, general ledger extracts, cost accounting, tax returns, payroll records, bank statements, and board or lender projections.

☐ Collect injury records where applicable: medical bills and records, employment and wage records, disability determinations, and out-of-pocket receipts.

☐ Collect contemporaneous projections prepared before the dispute for financing, budgeting, or planning. These will be the defendant's best cross-examination material, so obtain them first.

☐ Request the defendant's financial records where profits, ability to pay, or punitive damages are at issue.

☐ Preserve the mitigation record from day one — every substitute transaction attempted, with dates.

☐ Confirm retention periods for anything held by third parties: banks, payroll processors, insurers, and platforms.

☐ Document chain of custody for anything that may be authenticated at trial.

Phase 3 — The Computation and Its Disclosure

☐ Draft a preliminary computation by category in the first sixty days.

☐ For lost profits, build three components: a baseline from historical or comparable performance; a but-for projection; and a deduction of avoided variable costs.

☐ Use profit, not revenue. Confirm the avoided-cost ratio comes from the client's own cost accounting.

☐ Address foreseeability for any consequential damages in a contract case.

☐ Address reasonable certainty by stating the method, not merely the total.

☐ Reduce future damages to present value, and state the discount rate and its basis.

☐ Serve the computation under Rule 26 with the supporting documents.

☐ Supplement whenever the number moves materially, to avoid exclusion under Rule 37.

☐ Keep a version history showing what changed and why.

☐ Test the model against the client's own contemporaneous documents before the defendant does.

Phase 4 — Experts

☐ Retain early enough to shape discovery. An expert engaged after fact discovery closes works with whatever happens to exist.

☐ Match the expert to the category: forensic accountant or economist for lost profits; economist for earnings and present value; life care planner for future medical needs; vocational expert for earning capacity; industry expert for market assumptions.

☐ Define the assignment in writing, including the assumptions the expert is instructed to make and their source.

☐ Confirm the methodology satisfies Rule 702 of the Federal Rules of Evidence: sufficient facts and data, reliable principles and methods, and reliable application.

☐ Require that the report be replicable from its own four corners. A model no one else can reproduce is a model that gets excluded.

☐ Check for the recurring failures: revenue instead of profit; avoided costs omitted; growth assumptions inconsistent with the client's own projections; unverified client-supplied data; a damages period beyond any plausible recovery horizon.

☐ Comply with the report and disclosure requirements of Rule 26, including a complete statement of opinions and their basis.

☐ Prepare the expert for the reliability challenge, not only for cross-examination on the numbers. See expert witnesses and scientific evidence and retaining, disclosing, and challenging an expert witness.

☐ On the defense side, evaluate a motion under Rule 702; see challenging an expert under Daubert and Rule 702.

Phase 5 — Mitigation, Offsets, and Fault

☐ Build the mitigation record affirmatively: every substitute transaction sought, obtained, or refused, with dates and documents.

☐ Credit mitigation in the computation rather than waiting for the defendant to do it. A model that already accounts for it is far more credible.

☐ Identify offsets: benefits received, costs saved, and salvage value.

☐ Analyze the collateral source rule in the governing jurisdiction, including any statutory modification.

☐ Identify every lien and subrogation claim — health plans, providers, workers' compensation, government payors — and begin resolving them before settlement, not after. See negotiating a settlement and resolving liens before distribution.

☐ Assess comparative fault and the jurisdiction's system — pure, modified at fifty or fifty-one percent, or contributory.

☐ Assess joint and several liability and any allocation to non-parties, including settling and immune actors.

☐ Compute settlement credits under the jurisdiction's pro tanto or pro rata rule.

☐ On the defense side, prove failure to mitigate with specificity: the substitutes available, what the plaintiff did not do, and the amount avoidable. The burden is yours.

Phase 6 — Punitive Damages, Interest, Fees, and Tax

☐ Test the punitive standard: malice, fraud, oppression, or conscious disregard, at the applicable proof standard.

☐ Plan the ratio. State Farm Mutual Automobile Insurance Co. v. Campbell, 538 U.S. 408, holds that few awards exceeding a single-digit ratio satisfy due process, and BMW of North America, Inc. v. Gore, 517 U.S. 559, supplies the reprehensibility, ratio, and comparable-penalty guideposts.

☐ Do not rely on harm to non-parties to justify the award.

☐ Check state caps, bifurcation requirements, and split-recovery statutes.

☐ Check insurability of punitive damages in the jurisdiction, since it changes settlement dynamics.

☐ Compute prejudgment interest — availability, rate, and accrual date under the substantive law of the claim.

☐ Preserve post-judgment interest under 28 U.S.C. § 1961.

☐ Prepare the fee application with contemporaneous time records and rate evidence, if fees are available.

☐ Analyze taxation before any settlement: 26 U.S.C. § 104 for physical injury recoveries, 26 U.S.C. § 61 otherwise, and the treatment of fees in a taxable recovery.

☐ Allocate any settlement among claims in a way that reflects economic substance.

Phase 7 — Procedural Devices

☐ Consider an offer of judgment under Rule 68, served early, especially where the statute defines costs to include fees.

☐ On the plaintiff's side, evaluate any offer against the realistic range, not the aspirational one.

☐ Prepare the Rule 50 motion on damages, and renew it after verdict to preserve it.

☐ Anticipate remittitur under Rule 59.

☐ Consider bifurcation and its effect on the damages presentation.

☐ Consider partial summary judgment on a category that cannot be proved; see moving for summary judgment under Rule 56.

☐ Preserve the constitutional objection to any punitive award.

Phase 8 — Trial Presentation

☐ Build the damages exhibits as a self-contained set a juror could follow without the expert present.

☐ Use one summary exhibit that shows the categories and the total, with each line traceable to a supporting exhibit.

☐ Prepare the fact witnesses who explain the underlying records — the controller, the sales manager, the treating physician.

☐ Prepare the expert to teach the method, not merely to state the conclusion.

☐ Address mitigation and offsets affirmatively in the direct case.

☐ Prepare the verdict form with categories separated, so a defective category does not contaminate the whole award.

☐ Prepare damages instructions, including the reasonable certainty standard and the present value instruction.

☐ Preserve objections and the Rule 50 record.

Phase 9 — Enforcement

☐ Begin post-judgment discovery immediately — asset interrogatories, document requests, and a debtor examination.

☐ Record judgment liens on real property in every county where the debtor may own land.

☐ Garnish wages and accounts within the applicable limits.

☐ Levy on non-exempt personal property.

☐ Seek charging orders against partnership and limited liability company interests.

☐ Consider a receiver where a business or income stream must be managed.

☐ Domesticate the judgment in every state where enforcement is sought.

☐ Analyze exemptions and plan around them; see collecting a judgment or protecting exempt property.

☐ Investigate transfers made after the claim arose.

☐ Monitor for bankruptcy and be prepared to file a proof of claim and, where warranted, a dischargeability adversary proceeding.

☐ Calendar judgment renewal before the statutory lifespan expires.

A regional food manufacturer loses a private-label supply contract when the customer terminates in month fourteen of a thirty-six-month term.

Day one. Categories listed: expectation damages on the remaining twenty-two months; incidental costs of redeploying a dedicated production line; and a claim for the unamortized cost of tooling purchased for the customer. Documents named for each: the contract and purchase orders; the cost accounting showing contribution margin by product; the capital ledger for the tooling; and correspondence about the line.

Day two. Litigation hold issued to eleven custodians, with automatic deletion suspended. The controller confirms the general ledger and cost accounting are intact and that monthly production reports exist for the full fourteen months.

Day three. Statutory screen: none applies; this is a pure contract case. Fee screen: the contract has a prevailing party fee clause, which changes the settlement dynamics materially. Limitation screen: the contract contains a consequential damages waiver, which excludes the tooling claim as drafted but not the direct expectation claim — a finding that reduces the claim by $340,000 before a complaint is filed.

Day four. Collectibility: the customer is a public company with ample assets. No insurance issue. Collection probability effectively one.

Day five. Preliminary valuation: twenty-two months at contracted minimums, times contribution margin, less avoided variable costs, less mitigation reasonably expected — a range of $1.6 million to $2.3 million, against fees estimated at $400,000 to trial with a prevailing party clause running both ways.

Result. The client had believed the case was worth $5 million. The week's work produced a defensible range, identified the waiver before it became a surprise, and set up an early mediation that resolved at $1.85 million in month nine.

⭐ Key insight. Every item in that week was available on day one from documents the client already had. Nothing required discovery, and the analysis changed both the number and the strategy.

Worked Example: The Excluded Expert

A plaintiff's economist opines that a franchise lost $4.1 million in profits. The report projects revenue from the franchisor's system-wide averages, applies a margin the plaintiff supplied, and extends the projection eight years.

The defense motion under Rule 702 identifies four defects. The system-wide averages include locations in markets with no resemblance to the plaintiff's. The margin was supplied by the client and never verified against the plaintiff's own tax returns, which show a materially lower figure. The eight-year horizon exceeds the remaining franchise term. And the model deducts no incremental costs for the additional revenue it projects.

The court excludes the opinion. Without it, the plaintiff has no method, and the court grants judgment on damages under Rule 50.

Every one of those four defects was correctable at retention. The failure was sequencing: the expert was engaged after fact discovery closed, worked from what happened to exist, and was never asked to reconcile the margin against the tax returns that the defense obtained in discovery.

Timing Reference

Step	When	Consequence of missing it
Litigation hold	On reasonable anticipation	Spoliation sanctions under Rule 37
Collectibility assessment	Week one	Money spent on an uncollectible claim
Statutory screen	Week one	An easier theory missed
Initial computation	With initial disclosures under Rule 26	Exclusion of the theory
Expert retention	Before fact discovery closes	Expert works with incomplete data
Expert report	Per the scheduling order	Exclusion
Supplementation	Whenever the number moves	Exclusion of the revision
Offer of judgment	Early, and more than 14 days before trial	Cost-shifting protection lost
Rule 50 motion	Before submission, renewed after verdict	Issue not preserved
Fee and cost motions	Per Rule 54	Entitlement waived
Post-judgment discovery	Immediately	Assets move
Judgment renewal	Before the statutory lifespan ends	Judgment lapses

The Damages Computation Worksheet

Complete one per category, and keep them current.

Category: ______ Claim it arises under: ______

1. Legal measure. [Expectation / reliance / restitution / compensatory / statutory / equitable.] Authority: ______

2. Elements to prove. ______

3. Causation. How is this loss traced to the defendant's conduct rather than to other causes? ______

4. Foreseeability (contract only). Arose naturally, or within the parties' contemplation because ______.

5. Method. Baseline: ______ . But-for projection: ______ . Difference: ______ .

6. Avoided costs deducted. Amount: ______ . Source: ______ .

7. Mitigation credited. Amount: ______ . Documentation: ______ .

8. Offsets and collateral sources. ______

9. Present value (future amounts). Discount rate: ______ . Basis: ______ .

10. Supporting documents. Bates ranges: ______

11. Witness. Fact: ______ . Expert: ______ .

12. Anticipated attack, and answer. ______

13. Amount claimed. $______

14. Disclosure history. Initial: ______ . Supplements: ______ .

Notes. Line 12 is the one that improves a claim most. Write the defendant's best argument against the category and answer it in the model rather than at trial. Line 14 protects admissibility; a category revised without supplementation is a category at risk of exclusion.

Final Reminders

☐ Damages is a separate case requiring separate evidence, separate witnesses, and separate discovery.

☐ Reasonable certainty is about method, not precision. State the method.

☐ Profit, never revenue. Deduct the costs of earning it.

☐ Credit mitigation yourself; it makes the whole model credible.

☐ Disclose the computation, and supplement it every time the number moves.

☐ Retain the expert while there is still time to shape discovery.

☐ Screen for statutory damages before building an expensive model.

☐ Assess collectibility in week one and revisit it before every major expenditure.

☐ Resolve liens before distribution, not after.

☐ A judgment is not money. Plan enforcement from the beginning.

For Clients: What You Can Do

Much of the work above depends on materials only the client has. Three instructions, given at intake, prevent most later problems.

Stop deleting. The moment you think there may be a claim, suspend automatic deletion of email, retain phone records, keep bank and card statements, and tell anyone in the business who might purge records to stop. Damages are proved from ordinary business documents that ordinary retention policies destroy on schedule.

Write it down now. A dated log of what happened, what it cost, what you could not do, and what you tried to do about it. Two years later, a contemporaneous record is far more persuasive than recollection, and it becomes the backbone of testimony.

Take reasonable steps to limit the loss, and document them. Look for substitute work, get the repair estimate, seek the treatment, find another supplier. Doing so does not reduce the claim; failing to do it does. Keep the record of attempts that failed, because those prove reasonableness as effectively as the ones that succeeded.

Two cautions. Do not inflate the number — a figure that cannot be supported taints everything else, and a credible smaller claim is worth more than an incredible larger one. And ask early whether the other side has insurance or reachable assets, because that answer, more than the size of the harm, determines what is worth pursuing.

Clients who follow those three instructions hand their lawyer a case that can be valued in week one and proved at trial. Clients who do not hand over a story, and stories do not survive cross-examination on a damages model. The difference costs nothing at the outset and decides a substantial share of outcomes.

Give the three instructions at the first meeting, in writing, and confirm in month two that they were followed.

That single follow-up call catches the deletions, the missing log, and the mitigation nobody documented — while all three can still be fixed.

By month six, none of them can, and the damages case is whatever the surviving records happen to support.

That is a poor foundation for a claim that has to withstand a motion and a cross-examination.
