Expert
collaboration

Register of collaborating signing experts: academic profiles, senior site professionals, niche specialists and laboratories. Terms of collaboration and the real availability of instructions.

This page is addressed to experts. To consult an expert by subject: See the expert panel →

Terms of the register

Real availability of instructions

Joining the register does not carry any allocation of instructions. Frequency depends on a matter coming in whose subject matches the declared specialism, and that match is infrequent by definition: the files that justify bringing in an external expert are precisely those the forensic lead cannot resolve alone.

Assignment follows subject match, not availability. A geotechnics specialist does not receive a dispute about electrical installations. The restriction is deliberate: a report signed outside the signatory's evidenced specialism does not survive cross-examination.

The register works as a reference directory, not a job pool. Details are held so the expert can be reached on the day the subject matches, with no foreseeable timeframe: it may be a matter of weeks, or it may never happen.

Terms
01Registration creates no obligation and no exclusivity for either party.
02No minimum volume of instructions is guaranteed and no forecast is issued in writing.
03Contact is made with scope and fees already defined, so the decision rests on facts.
04No communications are sent outside an instruction compatible with the declared specialism.
05Removal and erasure of data on request, at any time — EU Regulation 2016/679.
§ Protocols

Two routes to standing

The route changes neither the technical work nor the fees: it changes what evidences the signatory before the court. Neither route is subordinate to the other.

Route A — Academic standing

University and teaching

Full professors, tenured lecturers and associate lecturers who combine teaching with their own professional practice.

  • Publications and standardisation committees as a documentary record
  • Engagement report by report, with no committed volume and no exclusivity
  • Compatibility governed by Spanish Act 53/1984 for civil servants
  • Invoiced independently or under the university's own arrangement
  • Court confirmation agreed and paid from the outset — art. 347 LEC
Register
Route B — Professional standing

Site, specialism, industry and professional bodies

Senior site professionals, niche specialists, former manufacturer or laboratory technical staff, and experts on other professional rosters. Practice evidences standing on its own: no teaching record is required.

  • Years of site direction, professional registration or laboratory accreditation as standing
  • Compatible with your own client base, with no exclusivity
  • Territorial coverage outside Catalonia through other professional rosters
  • Evidenced separation from the manufacturer, where the profile comes from industry
  • You may start as a specialist consultant, without signing, and move to signing later

What we do and what you do

We bring in the matter, qualify it technically, negotiate fees and deadlines with counsel or the insurer, prepare the case file, handle invoicing and take on all commercial contact. You receive an instruction that is already scoped: defined limits, ordered documentation and a specific technical question. You bring the judgement, validate the methodology, sign the report and confirm it in court if the proceedings require it.

The kind of matters that come in

Cases where the dispute turns on the calculation model, on the characterisation of a material or on the interpretation of a technical standard: structural pathology requiring reassessment, soil-structure interaction, service failures in installations, building systems behaving outside their product standard. These are technically demanding files — which is precisely why an academic profile is called for.

Compatibility and independence

Acting as an expert witness is compatible with university teaching and with private practice, but the specific position depends on each university's terms of engagement and, for civil servants, on Spanish Act 53/1984 on incompatibilities. Verifying that is each collaborator's responsibility. On our side, the report is governed by the expert's duty of impartiality (art. 335.2 LEC): what the analysis shows is what gets signed, whether or not it favours the instructing party.

Division of roles
The collaborator supplies the technical judgement; the practice, the rest of the file.
01Client acquisition and technical qualification of the matter
02Negotiation of fees, scope and deadlines
03Preparation of the case file and testing campaign
04Formal drafting, layout and procedural filing
05Invoicing, follow-up and dealings with counsel
Collaborator: technical judgement, signature and court confirmation

Technical profile declaration

Five steps. We do not ask for client names, case numbers or anything subject to confidentiality: only the subject matter you have reported on.

§ 05 · Contact

How do we reach you?

We will only write to you when there is a matter compatible with your specialism.

A verifiable public profile is worth more than an attached CV: it stays current and the court can check it. There is no need to send a CV.

Do not give client or party names, case numbers or anything subject to confidentiality.

Before you register

01Do I need to send a CV?+
No. Your qualification, your field and a verifiable public profile — LinkedIn, ORCID, Google Scholar, your department page or your laboratory's accreditation — are enough to assess the fit. If a specific matter calls for more, you will be asked then, by email. This register is not a selection process.
02Do I have to be a university lecturer?+
No. The register is open to site profiles, instrumental specialists, accredited laboratories and experts listed with other professional bodies. What is evidenced before the court is the signatory's record in the specific subject, and twenty-five years of site direction is a documentary record just as a publication is.
03How long before I receive an instruction?+
We cannot give you a timeframe. It depends entirely on a matter coming in whose subject matches your specialism. It could be weeks, or it could never happen. This page exists precisely so as not to create an expectation we cannot support.
04How are fees set?+
They are agreed case by case before the instruction is accepted, based on scope, technical complexity and whether court confirmation is expected. You receive a firm written proposal and decide then: registering commits you to nothing.
05Is this compatible with my university post?+
That depends on your terms of engagement and, for civil servants, on Spanish Act 53/1984 on incompatibilities. It is a check each collaborator must make with their own university. We cannot make it for you.
06Do I have to find clients or negotiate?+
No. Client acquisition, fee negotiation, file preparation and invoicing are ours. Your involvement begins once the instruction is defined and accepted.
07Must I sign the report and confirm it in court?+
In this route, yes: the signature is the core of expert-witness collaboration, and whoever endorses the report is the one who defends it. If the proceedings require confirmation in court, it is agreed from the outset and paid as part of the instruction (art. 347 LEC). If you would rather contribute your technical judgement without signing or appearing, the route is the specialist consultants register.
08I come from a manufacturer. Is that a problem for independence?+
It is if the relationship is still live. Once separation is evidenced, inside knowledge of the system is an asset: it allows declared performance and real equivalence between products to be assessed without representing any brand.
09What if the report harms the instructing party?+
It is issued all the same. The expert must act objectively and state so under oath or promise (art. 335.2 LEC). We do not accept instructions conditioned on an outcome, and we will never ask you to adjust a conclusion.
