Private investigator for Gibraltar and the Spanish frontier

Most Gibraltar-related matters do not stay in Gibraltar. People live on the Spanish side, hold property on the Spanish side, and cross the frontier daily — and that is exactly where a Spanish licence is what you need.

It's --:-- in Spain — an investigator is available now.

Straight answer about jurisdiction. Gibraltar is a separate jurisdiction with its own law, its own courts and its own regulation of private investigators. Our licence — TIP nº 6496 — authorises investigative work in Spain. We work the Spanish side of the frontier and the Campo de Gibraltar, which is where the majority of the relevant activity, property and residence actually sits. For work inside Gibraltar itself you need a Gibraltar-regulated investigator, and we will tell you so rather than take the instruction.

Why the frontier defines these cases

Gibraltar's working population substantially exceeds what a territory of that size houses, because thousands of people cross the frontier each day from La Línea, San Roque and the surrounding towns. A very large share of anyone connected to Gibraltar — employees, directors, spouses, debtors — actually lives in Spain.

That has a practical consequence that catches instructing firms out. A matter that presents as a Gibraltar problem is frequently, evidentially, a Spanish one: the residence is Spanish, the property is Spanish, the movements to be documented happen on Spanish roads, and the report will need to be admissible in a Spanish court if it is ever produced here.

The area also concentrates a distinctive client profile. Sotogrande and the surrounding urbanisations hold significant foreign-owned property, and the Campo de Gibraltar combines finance, gaming, shipping and bunkering activity with an ordinary cross-border commuter economy. The cases reflect that spread.

Areas we cover

The Spanish side of the frontier and the Campo de Gibraltar:

  • La Línea de la Concepción
  • San Roque
  • Sotogrande
  • Guadiaro
  • Torreguadiaro
  • Algeciras
  • Los Barrios
  • Castellar de la Frontera
  • Puerto de Sotogrande
  • Alcaidesa
  • Palmones
  • Tarifa

Sotogrande in particular generates its own casework: substantial properties held through companies, seasonal occupancy, and owners who are resident elsewhere for most of the year.

Local courts and registries

On the Spanish side, first instance proceedings for the frontier towns are heard at the Juzgados de La Línea de la Concepción and the Juzgados de San Roque, with Algeciras as the larger judicial centre for the comarca and the Audiencia Provincial de Cádiz above them. Property title is recorded at the Registros de la Propiedad of San Roque and La Línea.

Gibraltar's own Supreme Court, Land Registry and Companies House are separate institutions under separate law. Where a matter genuinely straddles both, the practical arrangement is a Spanish licensed detective for the Spanish evidence and a Gibraltar-regulated professional for anything inside the territory.

Common questions


Can you investigate inside Gibraltar?

No. Gibraltar regulates private investigators separately and our authorisation is Spanish. We work the Spanish side, and where a matter needs coverage inside the territory we say so at the outset instead of taking the instruction and improvising.

The subject works in Gibraltar but lives in Spain. Is that a problem?

That is the ordinary case here, and it is squarely within what we do. Residence, movements and property on the Spanish side can all be documented lawfully and produced in a Spanish court.

Will a Spanish report be accepted by a Gibraltar court?

That is a question for your Gibraltar lawyer and depends on their rules of evidence. What we can say is that the report is prepared to the Spanish standard and signed by a licensed detective, which is the necessary condition on this side.

Do we deal with you in English?

Throughout — first call to finished report. It is the point of the exercise, and in this area it removes a step rather than adding one.
