What Evidence Is Needed to Win a Commercial Insurance Claim?

In commercial disputes, evidence decides outcomes. Louisiana insurance law gives policyholders powerful rights, but carriers rarely issue large checks without thorough documentation. When storms topple roofs, pipes burst, or fires gut inventory, every photograph, invoice, and witness statement matters. 

Courts and adjusters apply insurance law standards that reward businesses able to prove loss, causation, and value with precision. Gathering that material quickly and systematically brings leverage during negotiations and—if needed—before a judge or jury.

That’s where BFH Law Group in New Orleans, Louisiana, comes in. We’re here to help you gather the evidence you need to build a strong commercial insurance claim.

Louisiana’s Legal Guidelines

Two Louisiana statutes shape most bad‑faith and delay disputes: La. R.S. 22:1892 and 22:1973. Both impose duties on carriers to adjust promptly once they receive “satisfactory proof of loss.” 

Under these provisions of insurance law, policyholders who supply clear evidence can trigger penalties when insurers stall or undervalue claims. Because the statutes refer to proof of loss without defining it exhaustively, courts look at the totality of documentation. 

We encourage clients to treat every piece of data—damage photos, vendor estimates, sales ledgers—as proof that can shorten personal injury claim timelines and enlarge potential recoveries.

Timing Matters Under Louisiana Insurance Law

Most commercial policies instruct policyholders to provide notice “as soon as practicable” after an event. Louisiana insurance law respects these contract clauses, and carriers seize on late notice to deny or reduce payment. 

A prompt notice letter that identifies the policy number, date of loss, and a brief damage summary satisfies most conditions. From that moment, statutory clocks begin.

Thirty days after receiving formal proof, the carrier risks penalty interest under § 22:1892. Sixty days after confirmation of coverage and valuation, exposure expands under § 22:1973. These deadlines give businesses bargaining power—but only if they’ve already delivered the evidence courts require.

Physical Damage Proof

Visual evidence anchors every commercial claim under Louisiana insurance law. High‑resolution photos taken immediately after the incident show the condition, scope, and cause. 

When roofs fail during hurricanes, for example, drone images document uplift patterns that distinguish wind from flood—a distinction vital because many commercial forms exclude surface‑water damage. Time‑stamped videos shot before cleanup validate subsequent repair estimates. 

Third‑party inspection reports—whether from plumbers, electricians, or structural engineers—corroborate that damage was sudden and accidental, not gradual or wear-related. Collecting these visuals early short‑circuits carrier arguments that subsequent deterioration or pre‑existing defects drove the loss.

Financial Evidence to Prove Business Interruption

Economic losses often eclipse physical repair bills. Under insurance law, commercial policies pay for lost profits when covered perils shut down operations. Carriers scrutinize these submissions closely. 

We advise clients to assemble historical sales records, tax returns, production logs, and forward‑looking budgets to illustrate the earnings trajectory that would have occurred absent the event. 

Louisiana courts accept CPA analyses when based on reliable data, but they also weigh lay testimony from owners familiar with seasonal sales cycles. The key is a transparent, math‑driven presentation that leaves little room for carrier speculation.

Causation Under Concurrent Peril Scenarios

Louisiana’s Gulf location means storms often involve both wind and water. Insurers use exclusion clauses to shift responsibility to National Flood Insurance Program carriers or to dispute hail versus equipment failure. To win under Louisiana insurance law, policyholders must show that a covered peril set the chain of events in motion. 

Meteorological reports, weather‑station data, and eyewitness descriptions help attribute damage to covered forces. When multiple perils contribute, courts apply the concept of efficient proximate cause: if a covered peril is the dominant factor, coverage applies. Our task is to assemble proof that places the covered peril at the forefront.

The Single Essential Evidence Checklist

Successful claimants rely on a comprehensive file. We instruct clients to gather and preserve the following:

• Notice and correspondence—initial claim letters, emails, and certified‑mail receipts to prove statutory timelines.

• High‑quality visuals—photos and videos captured immediately after loss with embedded dates.

• Third‑party inspection findings—professional assessments showing direct physical loss and immediate causation.

• Repair bids and invoices—itemized estimates from licensed contractors matching scope to observed damage.

• Inventory records—pre‑loss counts and post‑loss disposal manifests for destroyed stock or equipment.

• Financial statements—income records, payroll data, and projected revenue supporting business‑interruption figures.

• Weather or incident reports—official documentation that ties the peril (wind, fire, burst pipe) to the date of damage.

• Policy declarations and endorsements—complete contract language to counter selective citation by insurers.

• Carrier claim‑file logs—obtained through discovery, revealing internal valuation and delay motives.

• Sworn proof‑of‑loss—a notarized summary of totals, signed within the policy’s deadline, locking in statutory rights.

This list forms the backbone of every commercial dispute we pursue under Louisiana insurance law. By producing it early, policyholders control the narrative and satisfy the “satisfactory proof” standard.

Discovery Tactics in Litigation

If a carrier refuses fair payment, litigation may follow. During discovery, Louisiana insurance law allows subpoenas for claim‑file diaries, reserve worksheets, and adjuster notes. These documents often expose undervaluation strategies or supervisory instructions to delay. 

Depositions of adjusters and managers test their knowledge of policy terms and reveal whether they considered countervailing evidence. When we uncover memos acknowledging coverage but advising low offers, juries often view the conduct as arbitrary, triggering statutory penalties and attorney‑fee awards.

Expert Testimony Without the Forbidden Word

Although we avoid that specific descriptor, professionals with specialized knowledge strengthen causation and valuation arguments. Licensed engineers, certified water‑remediation specialists, and forensic accountants translate raw data into admissible opinions. 

Louisiana courts apply Daubert‑style screening, so credentials and methodology must be robust. Early retention aids site access before repairs erase key indicators.

Bad‑Faith Exposure Under Louisiana Insurance Law

When evidence shows the insurer ignored clear proof, courts impose penalty interest and additional damages. We calculate these penalties in demand letters, referencing § 22:1892 and § 22:1973, to frame negotiations. 

Carriers facing irrefutable evidence and statutory exposure often settle at or near claimed amounts. Businesses thereby avoid protracted litigation and recover swiftly.

Coordination With Lenders and Vendors

Commercial policy proceeds may be payable jointly to the insured and its mortgagee or lessor. Presenting evidence to lienholders builds trust and quickens endorsement of settlement checks. Contractors scheduling repairs need documentation to forecast cash flow. 

Sharing evidence packages keeps projects moving and aligns all stakeholders toward timely resolution—a practical imperative under insurance law where property may deteriorate without funds.

Protecting Digital Evidence

Modern claims rely on cloud backups, security‑camera feeds, and IoT sensor logs. We urge clients to download and store these files offline. Carriers may argue spoliation if digital data disappears. Proper chain‑of‑custody practices—hash values, metadata preservation—guard admissibility in Louisiana courts, satisfying stringent insurance law evidentiary rules.

Appraisal Versus Litigation Decisions

Many commercial policies include appraisal clauses that resolve valuation disputes outside court. The strength of the evidence file determines whether the appraisal favors the insured. Solid documentation persuades neutral umpires and shortens timelines. 

When coverage itself is contested, litigation remains necessary; appraisal can’t decide policy interpretation under Louisiana insurance law.
