Flood damage compensation means claiming damage caused by heavy rainfall or flooding from the insurer, the responsible administration or the person at fault, and it most often arises for vehicles damaged in a flood. For a driver whose comprehensive policy includes flood cover, the route is an insurance claim; a driver without comprehensive insurance may claim the damage from a responsible administration such as the municipality on the ground of inadequate infrastructure. The same event also raises questions of policy cover and building liability for homes and business premises.

On 14 October 2026, according to the Governor’s Office, Istanbul recorded its highest rainfall since measurements began in 1942; the Insurance Association of Türkiye reported that, in the initial phase, damage notifications had been made for 808 homes, 280 business premises and 76 vehicles. In such events, to whom, within what time and before which court a claim is brought depends on where and how the damage occurred. UTU Hukuk & Danışmanlık structures flood damage files in Istanbul and Ankara and in surrounding provinces such as Kocaeli, Sakarya, Yalova, Bursa and Tekirdağ by making this distinction from the outset.

The time limits are short and independent of each other: under comprehensive motor insurance, the damage is reported to the insurer within five working days from the date on which it became known, while for a compensation claim against the administration a written application to the administration is mandatory within one year from the date on which the act causing the damage became known. The first step in the file is therefore to record the evidence before it is lost and to determine the route to be followed.

Scope

What does a flood damage compensation lawyer handle?

UTU Hukuk provides litigation and advisory services in Istanbul, Ankara and surrounding provinces in flood and water damage claims on the following matters: Claims against the administration for uninsured vehicles, Insurance claims for vehicles with comprehensive cover, Diminution in value and uncovered losses, Vehicles with water in the engine, Damage in underpasses and on highways, Car parks and residential complex common areas, Preservation of evidence, Countering the force majeure defence and Homes, basements and business premises. A flood file rarely consists of a single claim. The headings below are claims arising from the same event that need to be assessed together.

01

Claims against the administration for uninsured vehicles

A written application to the responsible administration and a compensation action for an uninsured vehicle damaged because of deficiencies in stormwater drains, gully capacity or stream rehabilitation; determining the competent judicial route according to where the vehicle was damaged.

02

Insurance claims for vehicles with comprehensive cover

Checking whether the policy includes flood and inundation cover, the five-working-day notification and the loss adjustment process; if the claim is not met, comparing the Insurance Arbitration Commission with litigation.

03

Diminution in value and uncovered losses

Claiming from the responsible administration or a third party the diminution in value that cannot be recovered from the insurer where the comprehensive policy has no diminution in value clause, together with uncovered items such as the excess.

04

Vehicles with water in the engine

Not starting the vehicle before the loss adjuster arrives and recording the damage; reviewing the insurer’s grounds for rejecting engine damage against the general conditions, the policy’s special conditions and court decisions.

05

Damage in underpasses and on highways

Identifying the responsible administrations and bodies for a vehicle submerged in an underpass, swept away on the road or damaged while parked; preparing the case before the ordinary courts as required by Article 110 of the Highway Traffic Law.

06

Car parks and residential complex common areas

Separately assessing the liability of the operator or management and the service fault of the administration for vehicles damaged in a shopping centre or paid car park or in a residential complex car park.

07

Preservation of evidence

Requesting preservation of evidence through an on-site inspection and expert examination under Article 400 of the Code of Civil Procedure before the damage to the vehicle and the traces at the scene are lost.

08

Countering the force majeure defence

Demonstrating, against the administration’s extraordinary rainfall defence, that the damage was foreseeable and preventable, using meteorological station data and earlier floods at the same location.

09

Homes, basements and business premises

Reviewing the additional flood and inundation cover and the stock and machinery cover in home and business policies; assessing the liability of the building owner or the contractor for construction and maintenance defects such as insulation or drainage.

Authorities

Where was your vehicle damaged? Which authority and court are competent?

The most common mistake in flood cases is choosing the wrong judicial route. Decisions of the Court of Jurisdictional Disputes have held that the ordinary courts have jurisdiction where the vehicle was damaged on a highway (while parked, in motion or in an underpass), by reason of Article 110 of the Highway Traffic Law, and that the administrative courts have jurisdiction where it was damaged in an area outside the highway, such as a residential complex car park or vacant land. In administrative proceedings, an application to the administration is mandatory before a lawsuit is filed. For homes, business premises and vehicles with comprehensive cover, the first counterparty is usually the insurer.

  • Highway and underpass: Civil Court of First Instance
  • Residential car park and land: application to the administration, Administrative Court
  • Insured vehicle, home, business: insurer and Insurance Arbitration Commission
  • Building, management, contractor: Civil Court of First Instance and Consumer Court

Process

Time limits and steps after flood damage

In a flood file, the time limits run independently of each other. Missing one may also narrow the other routes.

01

First days: documentation

Photographs and videos showing the water level and location, the reference numbers of reports made to 112, the municipality and the water administration, the car park ticket, witness details and emergency repair invoices are kept. For vehicles with comprehensive cover, not starting the vehicle before the loss adjuster arrives prevents the damage from increasing.

02

Five working days: insurance notification

Under the general conditions of comprehensive motor insurance, the damage is reported to the insurer within five working days at the latest from the date on which it became known. If the period is missed, the right is not lost; under Article 1446 of the Turkish Commercial Code, only the damage that increased because of the delay may be deducted from the compensation according to the degree of fault.

03

One year: application to the administration

Under Article 13 of the Administrative Procedure Law, a written application is made to the relevant administration within one year from the date on which the act causing the damage became known and, in any event, within five years from the date of the act. If the administration does not respond within thirty days, the request is deemed rejected.

04

Sixty days: lawsuit

A full remedy action is filed within sixty days from the express rejection of the application or its rejection by silence; the competent court is the administrative court where the act took place. The power of attorney relationship and fees are set out in a written agreement before work begins.

Q & A

Flood damage compensation — frequently asked questions

If the damage results from a deficiency in the stormwater drains, gullies, stream rehabilitation or maintenance of the infrastructure, compensation may be claimed from the responsible administration. Collecting and removing rainwater is among the duties of the water and sewerage administration, while stream rehabilitation is among the duties of the metropolitan municipality; depending on the incident, the district municipality, the General Directorate of Highways or the State Hydraulic Works (DSİ) may also be responsible. The outcome of the claim depends on correctly identifying the responsible administration and establishing the service fault.

The owner of a vehicle without comprehensive (kasko) insurance may claim compensation from the responsible administration on the ground that the damage was caused by inadequate infrastructure. The route depends on where the vehicle was damaged: for vehicles damaged on a highway, the ordinary courts have jurisdiction; for those damaged in areas outside the highway, such as a residential complex car park, the administrative court comes into play. On the administrative route, a written application to the administration must first be made. Your vehicle’s own compulsory traffic insurance does not cover flood damage to your own vehicle.

Flood and inundation are not part of the main cover under the general conditions of comprehensive (kasko) motor insurance; they are added to the cover by an additional agreement. This cover is usually included in extended comprehensive policies, but the scope and excesses vary from policy to policy. The first step is therefore to check whether the policy includes “flood and inundation” cover and to review its special conditions. If the insurer does not meet the claim, an application may be made to the Insurance Arbitration Commission or a lawsuit may be filed.

Where a comprehensive policy includes flood cover, the general conditions do not expressly exclude damage caused by floodwater entering the engine. Court decisions show that damage caused by floodwater entering the engine has been treated as within the cover, and that restarting a vehicle that stalled in a flood has not been regarded as intentional conduct. However, insurers’ special conditions may contain different provisions; to prevent the damage from increasing, the vehicle should not be started before the loss adjuster arrives.

Under the general conditions of comprehensive motor insurance, the damage must be reported to the insurer within five working days at the latest from the date on which it became known; the “five days” mentioned in the news should be understood as working days. Missing this period does not automatically extinguish the insurance claim. Under Article 1446 of the Turkish Commercial Code, only the damage that increased because of the late notification may be deducted from the compensation, according to the degree of fault; if the insurer had already learned of the incident by other means, even this deduction cannot be made.

For a vehicle damaged in a paid or shopping centre car park, the liability of the car park operator and the service fault of the administration responsible for the infrastructure are assessed separately. In a residential complex car park, the management’s liability may arise from the maintenance of the pumps and drainage in the common areas. For claims against the administration, decisions of the Court of Jurisdictional Disputes have held that the administrative courts have jurisdiction for such areas outside the highway. The car park ticket, valet receipt and incident report should always be kept.

The competent court is determined by where and how the damage occurred. In decisions of the Court of Jurisdictional Disputes, the ordinary courts have been held to have jurisdiction for vehicles damaged on a highway, by reason of Article 110 of the Highway Traffic Law, and the administrative courts for damage in areas outside the highway, such as a residential complex car park. The General Assembly of Civil Chambers of the Court of Cassation has also accepted that collecting and removing rainwater is the duty of the water and sewerage administration. As choosing the wrong judicial route can cost years, this distinction should be made before a lawsuit is filed.

Yes. Under Article 13 of the Administrative Procedure Law, a person harmed by an administrative act must, before filing a lawsuit, make a written application to the relevant administration within one year from the date on which they learned of the act and, in any event, within five years from the date of the act. If the administration does not respond within thirty days, the request is deemed rejected. The lawsuit is filed in the administrative court within sixty days from notification of the rejection or from the expiry of the thirty-day period.

In such cases, administrations often argue that the extraordinary rainfall amounted to force majeure. However, a natural disaster removes the administration’s liability only if it was unforeseeable and unavoidable; court decisions show that a natural disaster does not break the causal link in every case and is sometimes treated only as a ground for reducing the compensation. Meteorological station data and previous floods at the same location are therefore decisive for the course of the case.

If the comprehensive policy has no diminution in value clause, diminution in value cannot be claimed from the comprehensive insurer. This item may be claimed from the administration or third party responsible for the damage; there are decisions ordering the administration to pay for the diminution in value of a vehicle damaged in a flood. In calculating diminution in value, the vehicle’s value before the damage is compared with its market value after repair, and the expert report is decisive.

Under the Disaster Insurance Law No. 6305, DASK (compulsory earthquake insurance) covers only material damage to buildings caused by earthquakes; it does not include flood and inundation cover. Flood damage to a home is covered by a home or fire policy if “flood and inundation” cover has been added to it as additional cover. The damage should be recorded with photographs and video and reported to the insurer without delay. If the water comes from the building’s insulation, drainage or the plumbing of the flat above, liability may lie with the building owner, the management or the neighbour.
