The role of the judicial property expert

The judicial expert is a professional appointed by the justice of the peace to provide technical insight on a rental dispute.

MissionExamples
Record damageDampness, cracks, mould
Determine causesConstruction defect, maintenance failure, liability
Assess costRepairs, restoration, property inventory
Verify complianceSanitary standards, electricity, EPC
Propose solutionsNecessary works, deadlines

The expertise is requested by a party or ordered by the court on its own initiative. It arises in disputes where documentary evidence is not sufficient.

The expertise process

1. Appointment and deposit

The court appoints the expert and sets a deposit (advance on costs). The requesting party must pay it at the clerk’s office within a set deadline (usually 1 month).

2. Expertise meeting

The expert summons the parties (and their lawyers) to the premises. They examine the property, take photos, ask questions and gather observations from each party.

3. Expert report

The expert writes a detailed report with their findings, analysis and conclusions. The parties can submit observations before the final report.

4. Court consideration

The court integrates the report into its decision. It is not bound by the expert’s conclusions but follows them in most cases.

[!important] Legal point The expertise can take several months. During this time, the dispute is suspended. Request provisional measures if the situation is urgent (unsanitary housing, danger).

Cost and coverage

ItemAmount
Deposit (advance)1,000-3,000 EUR
Final expert fees1,500-5,000 EUR
Travel expenses100-300 EUR
Average total2,000-4,000 EUR

Costs are advanced by the requesting party and reimbursed by the losing party at the end of the proceedings. The total court costs (expertise + lawyer + bailiff) can be significant.

In practice: when to request an expertise

Request an expertise when the dispute involves technical elements that the parties cannot resolve themselves. For simple disputes, conciliation or mediation are faster and less expensive.

Document everything in advance with a rental management software. Consult the rental disputes guide and protect yourself with a well-drafted lease.
