Court expert witness in mechanics and motor vehicles · Transport and logistics · Accidents and occupational risk prevention
I come from the motor trade, mechanics, industrial electronics, logistics and road haulage. I have spent years in the workshop, in the warehouse, in the technical office, in the after-sales support department and in the cab of a lorry, at the wheel of an articulated truck, wrestling daily with the tachograph, first the disc ones and later the digital. Today I turn my automotive training, my more than 30 years of professional experience and my court expert qualifications into expert reports that the judge understands and that, when needed, I defend and argue in the courtroom.
Cases I take
I am not a generalist expert with «expert» certificates in fields that were never their trade, the kind who values a flat today and a truck tomorrow, or anything else. I only give opinions on what I genuinely know first-hand, what has been my tool and my livelihood: motor vehicles, mechanics, road transport and logistics, trucks and the tachograph, warehouse machinery, forklift trucks, workplace accidents and risk prevention.
Thirty years of workshops, warehouses and roads. I know how and why a machine fails, and how to explain it to whoever has to judge it.

I cross-check the working time record against the tachograph files. That is where the unpaid hours show up.
Qualification: Court Expert in Working Time Records (300 h)
Who I work for
Everyone arrives with a different battle: the lawyer needs evidence that convinces the judge, the company needs an unfair penalty overturned, and the driver needs to get paid for the work done. I put the data on the table.
I give you a flawless technical report with a traceable methodology, and I defend it in court against the opposing expert. No hollow jargon: conclusions the judge grasps at first reading.
I have run companies and I know how much an Inspectorate penalty, a dispute with a driver or a fleet incident hurts. I defend you with data, not talk.
Independent damage assessment for industrial vehicles and machinery, and counter-reports when the figures do not add up. With the vehicle inspected in person, not from a photo.
Are you owed overtime and allowances? Your driver card tells the whole story, and I know how to make the judge see it. Sold a truck with a nasty surprise? We prove that too.
The difference
Most experts have never used a tachograph, never driven a truck and never once operated a forklift.
I first trained in general mechanics and the motor trade, then earned my living on the road, and then trained thoroughly to issue expert reports and defend your rights in court.
My foundation is general mechanics and the motor trade. Nobody needs to explain a truck to me with slides: I know how it works inside and where to look when something does not add up.
I have driven articulated trucks, operated forklifts and managed analogue and digital tachographs, as a driver and running companies. I know your day-to-day because it was mine.
An expert witness and ASPEJURE member, with LEC-compliant reports the judge understands at first reading. And one non-negotiable rule: the report says what the data says. If your case has no legs, I tell you before charging you anything.
Who I am
I come from the motor trade, mechanics, industrial electronics, logistics and road haulage.
That is the value I bring when defending your interests in the courtroom.
I trained in the motor trade, in vehicle mechanics and electrics, and later in road transport and court expert work.
I have earned my living in industrial machinery since 1989, first in the sale and after-sales service of industrial batteries — traction and stationary — and charging systems, and from 1995 with my own company, importing and distributing German-built batteries in Spain. I went as far as designing and building my own chargers, both transformer-based and high-frequency.
In recent years I have worked as after-sales manager in the forklift truck sector, as a service adviser at a company rebuilding and reconditioning automotive engines, and later as an articulated lorry driver, adding to the transport work the responsibility for fleet maintenance control and management.
I have driven trucks with CPC and ADR certificates, and I carry in my pocket my digital tachograph driver card and a licence covering all fourteen classes, from AM through C+E to D+E: there is no vehicle I assess that I am not legally entitled to drive on the public road. I have also defended workers as a union representative and legal representative of the workforce at my workplace, where I served as staff and occupational risk prevention representative.
Combustion engines, electric motors and their charging systems, the tachograph, trucks and forklifts are not something I know from a course alone: they have all been, and still are, part of my trade, and today they are also part of my qualifications and my expert specialisation.

What you get
Expert evidence is not won with adjectives. It is won when the other side tries to take it apart and cannot. That is why every report shows the calculation, cites the rule and carries the raw data in an annex: anyone can redo it step by step and reach the same figure.
What was asked, what comes out and how much it adds up to, in plain language. The judge, the prosecutor and the parties know what the case is about before reaching the technical part. The detail follows, for whoever wants to argue it.
Overtime is measured daily, weekly, fortnightly and annually, and the result changes a great deal depending on which one governs. A report that runs only one leaves hours unclaimed or claims hours that are not due. Here all four appear, with an explanation of which one prevails under your collective agreement.
National, regional and local public holidays for your province, and holidays placed where they were actually taken. This is no detail: the gap between calculating this way and estimating a pro rata runs to more than a hundred hours a year, and those hours are either paid or lost.
Regulation (EC) 561/2006, Royal Decree 1561/1995, the Spanish Workers’ Statute and the case law of the Court of Justice of the European Union and the Spanish Supreme Court on working time. With the specific article and judgment, so your lawyer can use them as they stand.
Every card analysed carries its SHA-256 fingerprint in the report, and so does the report delivered. If anyone disputes that the file is the same one, it takes a minute to check. Chain of custody stops being a phrase and becomes a number.
The day-by-day record, the rest periods, the vehicles driven and the places declared. No summary tables without a source: if a figure in the body of the report is disputed, the data behind it is there.
Perito Tacho Method MPT™
My reports are not written from scratch each time, nor bent to suit whoever is paying. They come out of a documented method of my own, the Perito Tacho Method, which always runs the same ten stages: intake of documents, chain of custody, cryptographic verification of every file, document control, classification, timeline reconstruction, working time, overtime, reconciliation and final audit. Every stage records what came in, what came out and what is missing. Technical fact and legal interpretation are always kept apart, and no calculation stands unless it can be reproduced.
Before anything reaches you, the report scores itself: documentary coverage, integrity, chain of custody, reproducibility, mathematical, chronological and legal consistency, and quality of evidence. You get a score, with its strengths and weaknesses stated in writing. If your case is weak, you will hear it from me before you hear it from the other side.
I simulate the court refusing a piece of evidence, the company never handing over the working time records, or the card having already overwritten the data. Then I tell you which conclusions still stand without it and which ones fall. You know in advance where the other side will attack and what you are left with if they win.
I know of no other expert who tells the client, in writing and before the hearing, what happens to the report if a piece of evidence is taken away. That is what separates a report from a defensible one.
Excellence is not the goal, excellence is the road.
How I work
A clear process, the same one for all nine specialities, with a fixed written quote before we start and no surprises along the way. As it should be.
You discuss your case with your adviser, or using the Driver Lex and Driver Docs apps on the Driver Solution portal, and you want to know the real scope and viability of the matter: this is where technical-expert advice comes in. You tell me the case and I review all the evidence before accepting the engagement. If the claim has legal legs, we get to work — and if it does not, the consultation will have cost you nothing.
I study the evidence in your case in depth, whatever the speciality: the TGD/DDD files from the driver and vehicle cards, which you can download free of charge with the Driver Tacho app on the Driver Solution portal; the technical documentation of the lorry, the trailer, the forklift or the car; workshop records and repair invoices; working time records, payslips and the applicable collective agreement; battery and charging point data; or the police report and the safety documentation of a workplace accident. From that documentary evidence I produce your technical expert analysis.
In accordance with articles 335 et seq. of the LEC (Spanish Civil Procedure Act — Law 1/2000, of 7 January), I draft and issue the technical-expert report in plain, clear language (in Spanish and/or Catalan, depending on the Autonomous Community where the legal action is brought) so that everyone in the courtroom can interpret and understand it.
My work does not end when the expert report is issued. I go with you to court, where I ratify and defend the report before the Tribunal and answer questions from the judge, the prosecutor and the parties.
Quotation
Every matter has its own scope, and putting the same label on all of them would be misleading you. What I do guarantee is the procedure: first I look at what you have, then I tell you whether the case stands up, and only then do I give you a fixed figure in writing. That figure does not move afterwards.
No obligation and no charge. Show me what you have: card downloads, printouts, contract, payslips, photographs, earlier reports. That is enough to see where the matter is going.
If the evidence will not support a solid report, I say so plainly and that is where it ends, with no invoice. I would rather lose an instruction than sign a report that collapses at the first hearing.
A fixed figure, with the scope set out and the deadline committed. If I need to travel to inspect the vehicle or the machine, or to attend the hearing, it is included and you see it before accepting.
Payment on account on acceptance and the balance on delivery. The clock starts when the documentation is complete, not before: without the collective agreement or the payslips the calculation does not hold.
FAQ-Frequently asked questions
Yes. I analyse tachograph data and documentation remotely; to inspect a vehicle or a machine, or to attend trial, I travel wherever needed.
Both. As a party-appointed expert, the report is filed with your claim or your defence; as a court-appointed expert, the court appoints me from the roster. The rigour is the same: the report says what the data says.
Tell me what happened and show me what you have: tachograph files or printouts, contracts, invoices, photos, previous reports. With that I do a no-obligation feasibility study. And if the evidence will not support a solid report, I tell you straight and do not make you spend money.
In Spanish or Catalan, whichever suits you and the court where it will be filed. In the courtroom I can defend it equally in either language.
For whoever engages the report: sometimes it is the company defending against a claim, sometimes the driver claiming what is owed. The sector's big advisory firms only work for companies; I am an independent expert, and my report says what the data says, whoever hires it.
It depends on the scope, which is why I will not put a label on it before looking at your case. The procedure is always the same: a feasibility study at no charge, then a fixed written quote that does not move. What I can tell you upfront is that I work below what is usual in court expert work, because the mechanical part of the job is automated and I pass that saving on to you.
Because overtime is set against the annual figure (arts. 34.1 and 35.1 of the Spanish Workers’ Statute). A single month can show whether driving limits were exceeded, but not how many overtime hours are due or what they are worth. Selling you a monthly report would mean charging for something you cannot then use to claim. If what you want is month-by-month monitoring, that is what Driver Tacho is for, which is a different thing and costs a fraction of this.
Ten working days from the moment I have all the documentation, not from the moment we speak. That distinction matters: the clock does not start while the collective agreement, the contract or the payslips are missing, because without them the calculation does not hold. If there is a hearing date looming, tell me at the outset and we will see whether we make it.
It depends on the matter, but for tachograph work the essentials are the driver-card downloads for the whole period, the employment contract, the applicable collective agreement and the payslips. When we accept the instruction I send you the exact list, marking what is essential and what merely helps, with the reason for each document. No asking you for whole folders just in case.
It is not, and that is why the report shows the calculation and carries the raw data in an annex: you can redo it, and so can the other side’s expert. A report that only holds up if nobody checks it is a report that collapses at the first hearing. Mine says what the data says, and if the data does not support you I would rather tell you before charging you.
