An independent expert, known as a contra-expert, can help when you disagree with the assessment of your insured damage. The central task is an independent evaluation of the damage amount. This differs from investigating whether the policy covers the event. Have the assignment and costs clearly defined beforehand. Kifid explains that reasonable costs of independent damage assessment may fall within the statutory framework, but that does not automatically mean every invoice is reimbursed in full. This guide concerns your own non-life insurance under Dutch law.

1. Decide what you want investigated
Read your insurer’s expert report before commissioning work. Which items are included or missing, and what valuation method was used? Specify what you dispute. Simply saying the amount is too low does not identify the necessary investigation. For a damaged floor, the disagreement may concern area, repair method or depreciation; these require different supporting evidence.
If the actual dispute concerns cause or coverage, discuss that with a lawyer first. Kifid distinguishes this from disagreement about the amount of insured damage. Technical investigation supporting coverage does not automatically have the same basis for costs. In a mixed dispute, have work relating to the amount separated from work on other questions.
2. Obtain the initial report and calculation
Request the damage estimate, photographs and relevant assumptions. Check whether the report is merely advice or part of an agreed binding determination. Keep forms already signed. Commissioning further work without knowing what has been agreed can create an unnecessary second dispute.
List missing or incorrectly described items yourself. For each, record the initial report’s description and your original evidence. Quotations, purchase records and maintenance information may help, but do not automatically use the same valuation standard as the policy. Your expert should explain how the proposed work helps establish that particular damage amount.
3. Choose expertise suited to the question
Ask a prospective expert about relevant experience, investigation methods and possible interests. Discuss who actually performs the work and whether access to the damage location is needed. An expert who mainly states a total without method or breakdown may fail to clarify the disagreement. Ask beforehand what report you will receive and which assumptions it uses.
Kifid explains that an insurer cannot simply restrict the statutory entitlement to a particular professional registration. That does not make quality irrelevant. Demonstrable expertise, a clear assignment and transparent reporting remain valuable. A lawyer assesses the legal dispute; a loss expert investigates the technical or financial damage question. Record each person’s role.
4. Make the assignment and costs transparent
Have the quotation itemise tasks, hours or rates, travel and additional costs. Ask how extra work is agreed and who contractually owes the invoice. An expert may say the insurer pays even though you are the commissioning client. Have the payment terms read too. Do not confuse expected reimbursement with a written commitment from your insurer.
The statutory framework concerns reasonable work and reasonable costs. Kifid says a preset maximum or restriction to the insurer’s own expert rate may conflict with that framework. At the same time the invoice must clearly show what necessary work was done. You may ask the insurer to comment on the quotation beforehand, without assuming that this settles every later cost issue conclusively.
5. Arrange investigation before evidence disappears
Record the condition before necessary repairs. Take overview and detailed photographs and keep relevant damaged parts where safe and practical. Coordinate access and the inspection time. If both experts can assess the same condition, the reasons for differing conclusions become clearer. Safety and preventing further damage remain important.
Give the expert the correct policy and earlier report, but separate your observations from technical conclusions. State when photographs were taken and by whom. Keep original files. If repairs have already happened, discuss honestly the resulting limitations. Do not silently fill missing information as if observed on site; a transparent limitation can be assessed more reliably.
6. Understand what the outcome decides
Read not just the final figure but the calculation, assumptions and missing information. Ask for explanations of differences from the first report. A higher figure in an independent report does not automatically oblige the insurer to pay it. The policy, any excess and other legal issues may remain relevant. Keep amount and coverage separate in correspondence.
Sometimes the agreed assessment procedure provides for a third expert or arbiter making a binding determination. Have the appointment document and mandate assessed before agreeing. Not every informal second opinion has this effect. If a dispute arises about the invoice or procedure, make a focused internal complaint and then examine whether Kifid or court is appropriate. Monitor separate deadlines too.
7. Fictional example: different repair methods
Suppose that after insured water damage the first expert estimates only local repairs to a wall. The owner thinks a larger area is damaged. He gathers photographs and asks an independent expert to assess area, repair method and associated costs. The assignment does not include whether the policy provides coverage at all; that is undisputed in this example.
The second report explains where the calculations differ. A lawyer can then assess whether the insurer rightly disputes the invoice and damage estimate, and what agreements were made. This fictional example proves no entitlement to entirely new repairs or full reimbursement of every expert invoice. It illustrates how a defined assignment clarifies matters better than a general request for a higher payout.
8. Checklist before signing
If unsure, contact an insurance lawyer before commissioning work. Ask what basis for costs exists, which assessment agreements apply and whether a complaint or evidence step is needed first. Explain the financial stakes and whether repairs are urgent. The assignment can then address the actual problem.
- Initial report, calculation and applicable policy conditions.
- Specific list of disputed items and original supporting documents.
- Quotation covering tasks, rates, extra work and payment terms.
- Any assessment deed, binding agreements and third expert appointment.
- Insurer’s written response to the assignment, costs and outcome.
Frequently asked questions
Should I choose the independent expert myself?
You can appoint your own expert, but first examine assessment agreements and the right question. Choose demonstrable expertise and a transparent assignment.
Is every invoice reimbursed in full?
No. Reasonableness of work and costs remains important. A statutory entitlement is not unrestricted reimbursement of every quotation or additional task.
Do the same cost rules apply to a coverage dispute?
Not automatically. Establishing the damage amount differs from investigating whether the event is insured. Have the basis for costs assessed beforehand.
Is a second report always binding?
No. That depends on the agreed procedure and assignment. Have an assessment deed or arbiter appointment examined before agreeing.
