Vehicle Diminished Value Claims After Traffic Accidents
28 October 2025
Pecuniary & Non-Pecuniary Damages in Personal-Injury Traffic Accidents
10 November 2025The Insurance Arbitration Commission (IAC) offers a faster, expert and cost-efficient pathway for policyholder–insurer disputes.
1) Legal Basis & Operation
- Disputes arising from insurance contracts may be decided by IAC upon written application.
- Independent arbitrators review the file; awards under a statutory threshold are final and enforceable as court judgments.
2) Eligible Disputes
- Motor TPL (diminished value, damage, loss of income)
- Casco/comprehensive (repair/total loss, accessories)
- Health (treatment costs, limits)
- Property/commercial/cargo/liability, life/personal accident claims.
3) 2025 Key Requirements
- Pre-request to insurer and 15-day wait (rejection/short-pay/no-reply).
- Finality threshold: awards up to TRY 300,000 are final; above this, Objection Board review may be sought.
- Time limit: 2 years from awareness of loss or policy expiry.
- Fee example: around TRY 650 in 2025 (case-dependent costs may apply).
4) Step-by-Step
- Written claim to insurer → await response for 15 days.
- IAC form + attachments (policy, expert report, invoices, photos, correspondence, IBAN).
- Pay fee and lodge the file.
- Arbitrator appointment (~7 days).
- Merit review (generally 4 months, extendable +2 months).
- Decision → 15-day objection window (if above threshold).
- Enforcement → final awards are directly enforceable.
5) Build a Persuasive File
- Itemize loss heads (parts, labor, rental car, diminished value).
- Support with expert opinions and numbers.
- Address policy limits/deductibles/exclusions explicitly.
- State interest (from default date) and costs/fees.
- Keep a clean trail of invoices, photos, emails/KEP.
6) Common Pitfalls
- Filing before 15-day waiting period lapses.
- Unquantified claims without expert backing.
- Ignoring deductibles/limits and exclusions.
- Over-reliance on equity without figures.
7) Skeleton of an IAC Petition (Concise)
- Parties & policy
- Facts & chronology
- Claims table (amounts, interest, costs)
- Legal grounds (contract terms, general principles)
- Evidence list
- Prayer for relief
8) After the Award
- Non-payment → judicial enforcement.
- Partial success/above threshold → consider objection.
- Review tax/accounting impacts and potential recourse.
