In recent years, many residents of Spain have turned to a simple way to protect their homes—placing stickers or signs on doors and windows warning of an alarm system. This measure seems effective for deterring intruders, but not everyone is aware that such a practice, without a real security system, can result in a fine.
Spanish law strictly regulates matters related to private security and the use of security company insignia. According to the current private security law, it is prohibited to imitate security services without the proper authorization. This means that individuals are not allowed to use logos, names, or other identifying marks of security firms unless they have a valid service contract.
The law also prohibits placing advertising materials that create the impression that a property is under the protection of a professional service when this is not the case. Violating this rule can lead to administrative liability and significant financial penalties.
The fine for the illegal use of stickers or signs bearing security company insignia can reach several thousand euros. In some cases, if trademark rights are infringed, the amount claimed can be at least 600 euros for each day the mark is misused. Additionally, there may be further claims for damages.
The unauthorized use of official security company insignia can be prosecuted as a crime against industrial property. In especially serious cases, offenders face not only fines but also criminal liability, including imprisonment for up to three years.
If a sticker or sign misleads other individuals, such as tenants or buyers, this can be regarded as unfair advertising. In such cases, competition law provides for additional sanctions, including fines and even imprisonment for up to two years.
Some municipalities in Spain also have their own regulations and fines for such violations. Depending on the region, penalties can range from 100 to 3,000 euros.
To avoid legal issues, experts recommend using only neutral signs without reference to specific companies. For example, phrases like “Property under protection” or “Video surveillance in progress” without company logos or names do not violate current legislation. Such warnings may be posted on private property as long as they remain within the owner’s premises.
For additional home protection, you can install autonomous security systems—motion sensors, surveillance cameras, or timers for lights. These devices do not require connection to a central monitoring service and are not subject to private security laws.
For maximum protection, it is recommended to sign a contract with a licensed security company. In this case, the company will provide an official sign, and your property will truly be monitored by professionals.
Overall, trying to save on security with fake stickers can result in serious financial and legal consequences. Spanish law clearly prohibits the imitation of security services and the use of other companies’ trademarks without permission. To protect your property, it’s better to choose legal and proven methods to avoid any trouble.
