1. Common dispute types

Commercial insurance (property, cargo, liability, credit…) disputes typically fall into five groups:

  1. Full claim denial — the insurer says the event is outside coverage.
  2. Reduced indemnity — disagreement over loss value or deductibles.
  3. Delayed payment — complete file, but money "stuck" for months.
  4. Unilateral termination — disputes over termination rights and premium refunds.
  5. Beneficiary disputes — when insured assets were transferred or mortgaged to a bank.

2. Why insurers deny claims

Common denial grounds — and how to diagnose each:

  • Exclusion clauses: the loss falls under an exclusion (war, wear and tear, wilful misconduct…). → Re-read the insured-event definition and exclusion list in your actual policy, not the marketing summary.
  • Disclosure breach: the policyholder failed utmost-good-faith disclosure or to notify increased risk. → The insurer's strongest weapon; re-check the signed application.
  • Insufficient loss proof: no loss-adjustment report, no repair/replacement invoices. → Losses must be quantified with documents.
  • Late loss notification: many policies set notification deadlines (e.g. 24–48 hours for cargo). → Check notification clauses the moment an event occurs.

3. Four-step handling process

Step 1: Written complaint

Send a formal complaint: state the claim, cite policy clauses, attach documents; demand a written reply with denial reasons and clause references. Confirm every oral exchange in writing/email.

Step 2: Negotiation, mediation

Most insurance disputes settle here — insurers often pay a portion to avoid proceedings. Prepare your walk-away position (minimum acceptable) before sitting down.

Step 3: Litigation or arbitration

Per the contract's dispute clause: commercial arbitration if agreed; otherwise the competent court. Attach the full evidence set (section 4) to the claim.

Step 4: Enforcement

Winning is half the journey — monitor enforcement to recover indemnity plus late-payment interest (if awarded).

4. Evidence checklist

  • ☐ Policy / insurance certificate + endorsements, amendments.
  • ☐ Application and disclosure documents at inception (proving good-faith disclosure).
  • ☐ Loss-adjustment reports (independent adjusters preferred).
  • ☐ Invoices proving loss value and remediation costs.
  • ☐ Loss notification and proof of timely notice.
  • ☐ The insurer's denial/reduction letter.
  • ☐ All correspondence between parties.

Golden rule: in insurance disputes, the side with more complete documentation usually wins. Photograph the scene, keep emails, never rely on phone calls alone.

5. Limitation and forum notes

  • Limitation period: insurance-contract disputes are subject to statutory limitation — don't let it expire before suing. It typically runs from when the dispute arose (often receipt of the denial letter).
  • Forum: per the contract (arbitration or court). Without an arbitration agreement, sue in court.
  • Applicable law: the 2022 Law on Insurance Business is the specialist statute; general contract matters follow the 2015 Civil Code and 2005 Commercial Law.
