How Much Does a Computer Forensics Expert Cost in Spain? 2026 Rates
By Juan Jesús Merino Carretero, chartered computer engineer no. 89 (CPIIEX) computer forensics expert price · rates · guide
One of the first questions for anyone who needs a computer forensics expert is how much it costs. Most websites in the sector avoid the subject, which only adds uncertainty for someone who is already facing a lawsuit or an incident. In this article we give real indicative figures for the Spanish market in 2026, explain what lies behind each range and why a cheap expert report can turn out very expensive if the report can be challenged or the expert does not appear in court.
How much a computer expert report costs: real ranges
The price depends on three factors, listed in order of impact:
- Technical complexity of the case (number of devices, volume of data, type of evidence).
- Estimated time for analysis and writing.
- Defense in court: whether it is included, whether it requires travel, number of appearances.
These are the most common indicative ranges in Spain in 2026:
| Type of expert work | Indicative price (€) | Timeframe |
|---|---|---|
| Validation of messaging (WhatsApp, SMS) on a single device | 600 – 1,200 | 5-10 days |
| Forensic analysis of an email (headers, access) | 700 – 1,400 | 5-10 days |
| Data recovery on a drive/SSD for use as evidence | 800 – 2,000 | 1-3 weeks |
| Forensic analysis of a single computer (PC, laptop) | 1,500 – 3,500 | 2-4 weeks |
| Forensic analysis of a phone (Android / iPhone) with deep extraction | 1,200 – 2,800 | 2-3 weeks |
| Investigation of an information leak in a corporate environment | 3,000 – 8,000 | 3-8 weeks |
| Investigation of a computer intrusion (corporate network) | 3,500 – 12,000 | 4-10 weeks |
| Expert valuation of an IT system or software | 800 – 3,000 | 2-4 weeks |
| Defense of the report at trial (in-person session) | 400 – 800 / session | – |

What a serious quote should include
A professional quote itemizes the following:
- Preliminary feasibility analysis: whether the expert work is technically possible and procedurally useful.
- Collection and custody of the evidence (bit-for-bit cloning, hashes, handover record).
- Forensic analysis itself, with the estimated number of hours.
- Writing of the expert report with annexes (screenshots, logs, hashes, methodology).
- Defense in court if summoned by the court.
- VAT and possible travel.
If the quote you receive does not contain these items, ask for clarification in writing before accepting.
Why a cheap expert can turn out very expensive
In computer expert work, price is only one part of the real cost. What truly determines the ROI of the expert report is whether it holds up in court. These are the most frequent risks with low-cost expert work:
- Poorly documented chain of custody: the opposing party’s expert asks for the report to be declared null for formal defects. Case lost.
- Hashes not calculated: there is no way to prove the evidence analyzed was not tampered with.
- Non-reproducible methodology: the judge cannot assess the evidence.
- Expert without a degree or not registered: the report loses procedural value.
- The expert does not attend trial: the report is left undefended and the opponent’s objections go unanswered.
The real cost of a challenged expert report is losing the entire case, which in a divorce can mean tens of thousands of euros and in a commercial dispute far larger sums.
Is there a subsidy or free legal aid for expert reports?
In criminal proceedings, when the case is pursued ex officio, the experts are appointed by the court and the fees are covered by the administration (at set rates). Under free legal aid (court-appointed duty counsel), if granted, expert fees are covered from public funds according to the official scale. In all other cases (party-appointed expert), the cost is borne by whoever commissions the report, although it can be recovered as court costs if the court so finds.
For more details on how an expert is designated and who pays, see our guide to the designation of a court-appointed computer expert.
Hourly rate vs. fixed price
There are two billing models in the sector:
- Hourly rate: the expert bills the actual hours spent (between €60 and €150/h depending on specialty). It applies when the scope is highly variable or when the case evolves.
- Fixed price: the expert gives a fixed amount after analyzing the case. It is the option preferred by most law firms because it makes recovery as costs easier and eliminates surprises.
Forenlab preferably works with a fixed price because it offers predictability to the client and the lawyer.
When it is worth not saving on the expert
There are three situations in which saving €500 on the expert is a terrible idea:
- High-value cases (>€30,000 at stake): the difference in quality between experts pays for itself many times over.
- Cases where the opposing party has a high-level expert: you need to match or exceed the technical quality of the opponent.
- Cases that depend on a single key technical finding: the expert report is the case. Without a solid report, there is no lawsuit.
Frequently asked questions
Is VAT included in the price?
If the expert is self-employed or a company, VAT is applied at 21%. Always ask for the quote to itemize the taxable base + VAT.
Is there a down payment?
The usual arrangement is to pay 30-50% when signing the engagement and the rest on delivery of the report. Some experts charge 100% up front in short-deadline cases.
Do court costs cover the expert report?
If the judgment orders the opposing party to pay costs and the expert report was necessary, it can be included in the assessment of costs. Inclusion depends on the court and the amount.
Why is there such a big price difference between experts?
Because of experience, specialization, equipment (own laboratory, certified tools) and whether the cost of defense in court is included. Always ask for a breakdown.
