Knock for Knock Agreement
Insurance Glossary
When two vehicles insured by different insurers collide, a knock-for-knock agreement is a practice where each insurer pays for the Own Damage (OD) of its own policyholder, regardless of which party was at fault. This arrangement is primarily applied in motor insurance, and is followed in certain regions to simplify and speed up claim settlements.
What is a Knock-for-Knock Agreement?
A knock-for-knock agreement is an understanding between motor insurance companies where each insurer compensates its own policyholder for vehicle damage after an accident. Instead of investigating fault or recovering money from the other insurer, each company handles its own customer’s claim. This avoids lengthy fault determination processes and reduces disputes between insurers.
Where is it Applicable?
Knock-for-knock agreements are followed mainly in:
- United Kingdom (UK) – highly structured and widely recognized
- India – informal operational practice, limited to Own Damage
- Parts of Europe – in certain motor insurance markets
- Australia – used in some fleet and commercial vehicle arrangements
It is not used in the USA, where fault-based liability systems dominate.
Geographical Differences
United Kingdom
- Recognized industry-wide through structured ABI (Association of British Insurers) agreements.
- Can apply to both Own Damage and some third-party elements, depending on insurer arrangements.
- Highly standardized and consistently followed.
India
- Exists only as an informal operational practice among insurers.
- Applies only to Own Damage (OD) claims.
- Third-party liability claims must follow Motor Vehicles Act procedures.
- Variations may exist across insurers, as there is no central binding agreement.
Europe (Example: Ireland)
- Some insurers use knock-for-knock arrangements for fleet vehicles or mutual settlements.
- More structured than India but less formalized than UK.
- Primarily applies to Own Damage to speed up settlements.
Example Scenario
Two vehicles collide in a traffic intersection:
- Car A is insured with Insurer X
- Car B is insured with Insurer Y
- Both cars have Own Damage coverage
Under a knock-for-knock agreement:
- Insurer X pays for the damage to Car A
- Insurer Y pays for the damage to Car B
- Neither insurer pursues the other for reimbursement
- No dispute occurs about which driver caused the accident
This accelerates claims processing and avoids back-and-forth negotiations.
Benefits of Knock-for-Knock Agreements
1. Faster Claims Settlement
Insurers do not wait for police reports, fault determination, or recovery attempts from the other insurer.
2. Lower Administrative Costs
Reduces legal involvement, investigation, documentation, and manpower costs.
3. Avoids Disputes Between Insurers
Since each insurer pays its own customer, arguments about fault or liability are minimized.
4. Better Customer Experience
Policyholders receive quicker repair approvals and settlement.
5. Operational Efficiency
Speeds up the overall claims workflow for insurers, especially for high-frequency motor collisions.
IT / Systems Implications
Knock-for-knock practices affect insurer systems and claim workflows in several ways:
1. Claims System Configuration
- Claims must be categorized as knock-for-knock eligible or non-eligible.
- System must bypass fault-related fields for OD claims under this framework.
2. Reduced Recovery / Subrogation Processing
- Systems must automatically mark recovery/subrogation as not applicable for such claims.
3. Reporting and Regulatory Data
- Reports must identify knock-for-knock OD claims separately for internal audit and portfolio analysis.
A knock-for-knock agreement is a motor insurance practice where each insurer handles the repair cost for its own policyholder’s vehicle, regardless of fault. While fully formalized in the UK, it is an informal operational mechanism in India, and used selectively across Europe and Australia. This arrangement improves customer experience, accelerates claims, and reduces insurer disputes, supported by streamlined IT workflows.
