Validity of evidence"},"content":{"rendered":"&#013;\n<p class=\"wp-block-paragraph\">It&#8217;s one of the first doubts that arise before taking the step: is it legal to hire a <a href=\"https:\/\/cromadetectives.com\/en\/services\/infidelity\/\">detective to investigate infidelity<\/a>? The answer is yes, but with important nuances that are worth knowing before starting, both to protect your interests and to ensure that the investigation&#8217;s outcome is useful. <\/p>&#013;\n&#013;\n<p class=\"wp-block-paragraph\">In this article, we explain the legal framework that regulates these investigations, what a detective can and cannot document, and what validity the evidence obtained has if it ends up being necessary in a separation or divorce process.<\/p>&#013;\n&#013;\n<h2 class=\"wp-block-heading\">The legal framework regulating infidelity investigations<\/h2>&#013;\n&#013;\n<p class=\"wp-block-paragraph\">Los detectives privados en Espa\u00f1a operan bajo la Ley de Seguridad Privada (Ley 5\/2014) y su reglamento de desarrollo. Para ejercer legalmente, una agencia debe estar inscrita en el Registro Nacional de Seguridad Privada del Ministerio del Interior y sus investigadores deben contar con la habilitaci\u00f3n profesional correspondiente. <\/p>&#013;\n&#013;\n<p class=\"wp-block-paragraph\">Within this framework, infidelity investigation is one of the expressly recognized activities. It is not a legal loophole or a gray area: it is a regulated service, with defined limits and supervised by the Ministry of Interior. <\/p>&#013;\n&#013;\n<h2 class=\"wp-block-heading\">What a detective can investigate and document<\/h2>&#013;\n&#013;\n<p class=\"wp-block-paragraph\">A licensed private detective can document everything that occurs in public spaces. This includes: <\/p>&#013;\n&#013;\n<ul class=\"wp-block-list\">&#013;\n<li>Travel and movements in public thoroughfares<\/li>&#013;\n<li>Presence in public places: restaurants, hotels, events, third-party residences viewed from the exterior<\/li>&#013;\n<li>Meetings with other people in publicly accessible spaces<\/li>&#013;\n<li>Visible activity on publicly accessible social media<\/li>&#013;\n<\/ul>&#013;\n&#013;\n<p class=\"wp-block-paragraph\">All of this, provided the detective does not interfere with or condition the behavior of the investigated person, can be documented and used as evidence.<\/p>&#013;\n&#013;\n<h3 class=\"wp-block-heading\">Sobre las redes sociales<\/h3>&#013;\n&#013;\n<p class=\"wp-block-paragraph\">Un detective puede consultar y documentar el contenido p\u00fablico de un perfil en redes sociales, del mismo modo que cualquier persona podr\u00eda hacerlo. Lo que no puede hacer es acceder a un perfil privado, crear cuentas falsas para conseguir que la persona investigada le acepte como contacto, o utilizar cualquier tipo de enga\u00f1o para acceder a contenido restringido. Ese tipo de actuaci\u00f3n vulnera el derecho a la intimidad y puede anular la prueba por completo, adem\u00e1s de tener consecuencias legales para quien la realiza.  <\/p>&#013;\n&#013;\n<h2 class=\"wp-block-heading\">What a detective cannot do under any circumstances<\/h2>&#013;\n&#013;\n<p class=\"wp-block-paragraph\">The limits are just as important as the possibilities. A private detective cannot: <\/p>&#013;\n&#013;\n<ul class=\"wp-block-list\">&#013;\n<li>Access a home or record inside it without consent<\/li>&#013;\n<li>Intercept calls, messages, or emails<\/li>&#013;\n<li>Access private social media accounts through deception or impersonation<\/li>&#013;\n<li>Install tracking or listening devices without authorization<\/li>&#013;\n<li>Actuar fuera del alcance definido en el encargo con el cliente<\/li>&#013;\n<\/ul>&#013;\n&#013;\n<p class=\"wp-block-paragraph\">Cualquier prueba obtenida vulnerando estos l\u00edmites es nula de pleno derecho. No solo no sirve como prueba, sino que puede constituir un delito contra la intimidad tanto para el detective como, en determinados casos, para quien contrat\u00f3 el servicio conociendo esa irregularidad. <\/p>&#013;\n&#013;\n<h2 class=\"wp-block-heading\">Is a detective&#8217;s evidence valid in a separation or divorce process?<\/h2>&#013;\n&#013;\n<p class=\"wp-block-paragraph\">S\u00ed, siempre que se hayan obtenido dentro de los l\u00edmites legales que hemos descrito. Los tribunales espa\u00f1oles admiten con normalidad los informes de detective privado como prueba documental, y su valor probatorio suele ser alto precisamente porque procede de un profesional homologado que ha actuado conforme a la ley. <\/p>&#013;\n&#013;\n<p class=\"wp-block-paragraph\">Este tipo de prueba puede ser relevante en varios contextos:<\/p>&#013;\n&#013;\n<ul class=\"wp-block-list\">&#013;\n<li>Procedimientos de separaci\u00f3n o divorcio, especialmente si hay disputa sobre el reparto de bienes o pensiones<\/li>&#013;\n<li>Procesos de custodia, cuando la conducta de una de las partes puede afectar al bienestar de los menores<\/li>&#013;\n<li>Situations of extramarital cohabitation that affect prior financial agreements<\/li>&#013;\n<\/ul>&#013;\n&#013;\n<p class=\"wp-block-paragraph\">The report alone does not decide a judicial proceeding; it is the judge who evaluates the evidence along with the rest of the case. But a well-prepared report, with solid and legally obtained documentation, carries considerable weight. <\/p>&#013;\n&#013;\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-2373 size-large\" src=\"https:\/\/cromadetectives.com\/wp-content\/uploads\/2026\/06\/legalidad-detective-infidelidades-1024x576.webp\" alt=\"\" width=\"1024\" height=\"576\" srcset=\"https:\/\/cromadetectives.com\/wp-content\/uploads\/2026\/06\/legalidad-detective-infidelidades-1024x576.webp 1024w, https:\/\/cromadetectives.com\/wp-content\/uploads\/2026\/06\/legalidad-detective-infidelidades-300x169.webp 300w, https:\/\/cromadetectives.com\/wp-content\/uploads\/2026\/06\/legalidad-detective-infidelidades-768x432.webp 768w, https:\/\/cromadetectives.com\/wp-content\/uploads\/2026\/06\/legalidad-detective-infidelidades-1536x864.webp 1536w, https:\/\/cromadetectives.com\/wp-content\/uploads\/2026\/06\/legalidad-detective-infidelidades.webp 1672w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/p>&#013;\n<h2 class=\"wp-block-heading\">Por qu\u00e9 la v\u00eda profesional es la \u00fanica segura<\/h2>&#013;\n&#013;\n<p class=\"wp-block-paragraph\">Attempting to obtain this type of evidence on your own is the most common mistake and the one that generates the most problems later. Checking another person&#8217;s phone without their consent, accessing their social media with a fake account, or installing a tracking application are behaviors that can constitute a crime, regardless of whether the suspicion of infidelity is true or not. <\/p>&#013;\n&#013;\n<p class=\"wp-block-paragraph\">A licensed private detective knows exactly where the limits are and always works within them, which protects both the person hiring the service and the validity of the final result.<\/p>&#013;\n&#013;\n<p class=\"wp-block-paragraph\">If you want to understand how this process unfolds step by step, we explain it in <a href=\"https:\/\/cromadetectives.com\/en\/signs-of-infidelity-and-how-it-is-investigated-what-a-private-detective-does\/\">how infidelity is investigated and what a private detective does<\/a>.<\/p>&#013;\n&#013;\n<h2 class=\"wp-block-heading\">How to take the first step with guarantees<\/h2>&#013;\n&#013;\n<p class=\"wp-block-paragraph\">Hiring a licensed private detective is the only way to ensure that the investigation remains within legality and that, if the result is needed later, it has the necessary validity.<\/p>&#013;\n&#013;\n<p class=\"wp-block-paragraph\">If you want to know how the hiring process works from the first contact to the delivery of the report, we explain it in <a href=\"https:\/\/cromadetectives.com\/como-contratar-detective-privado-infidelidad\/\">how to hire a private detective for infidelity<\/a>.<\/p>&#013;\n&#013;\n<h2 class=\"wp-block-heading\">Frequently Asked Questions<\/h2>&#013;\n&#013;\n<h3 class=\"wp-block-heading\">\u00bfPuede un detective seguirme a m\u00ed tambi\u00e9n si contrato el servicio?<\/h3>&#013;\n&#013;\n<p class=\"wp-block-paragraph\">No. El detective act\u00faa exclusivamente sobre la persona objeto de la investigaci\u00f3n, definida en el encargo con el cliente. No tiene ning\u00fan motivo ni autorizaci\u00f3n para investigar a quien contrata el servicio.  <\/p>&#013;\n&#013;\n<h3 class=\"wp-block-heading\">Is it a crime to be investigated without my knowledge?<\/h3>&#013;\n&#013;\n<p class=\"wp-block-paragraph\">No, as long as the investigation remains within the legal limits we have described: public spaces, without intercepting private communications or accessing intimate spaces without consent. Discretion is part of the process, not an irregularity. <\/p>&#013;\n&#013;\n<h3 class=\"wp-block-heading\">Can I use social media screenshots as evidence instead of hiring a detective?<\/h3>&#013;\n&#013;\n<p class=\"wp-block-paragraph\">You can provide them, but their evidentiary value is usually limited if they are not accompanied by a verifiable context. A detective&#8217;s report provides date, place, circumstances, and a chain of custody of the information that a simple screenshot cannot offer. <\/p>&#013;\n&#013;\n<h3 class=\"wp-block-heading\">What happens if the other party challenges the detective&#8217;s report in court?<\/h3>&#013;\n&#013;\n<p class=\"wp-block-paragraph\">Puede hacerlo, como con cualquier prueba. Si el informe se ha obtenido correctamente y la agencia est\u00e1 homologada, lo habitual es que el informe se sostenga. El detective, adem\u00e1s, puede ser llamado a ratificar su contenido ante el juzgado si es necesario.  <\/p>&#013;\n&#013;\n<h2 class=\"wp-block-heading\">Actuar con garant\u00edas desde el primer momento<\/h2>&#013;\n&#013;\n<p class=\"wp-block-paragraph\">La legalidad de una investigaci\u00f3n por infidelidad no depende de la sospecha en s\u00ed, sino de c\u00f3mo se lleva a cabo. Contar con una agencia homologada es lo que marca la diferencia entre obtener informaci\u00f3n que puedas usar con tranquilidad y arriesgarte a que todo el proceso no sirva para nada, o incluso te genere un problema legal a\u00f1adido. <\/p>&#013;\n&#013;\n<p class=\"wp-block-paragraph\"><strong>Do you have doubts about whether your situation can be legally investigated?<\/strong> Cons\u00faltanos sin compromiso.
