About us

Blay JD is a highly qualified law firm with a solid track record in Criminal Law and the defense of fundamental rights. We have successfully led complex proceedings related to economic crimes (money laundering, fraud, corporate offenses), organized crime, and have been part of the Legal Aid Scheme of the Madrid Bar Association.

Currently, the firm expands its activity by offering specialized advice in four key areas: medical claims due to deficiencies in the public health system (such as ambulance delays or waiting lists that force patients to seek private healthcare), compensation for wrongful pre-trial detention, collective claims for international scams, failed investments, or cryptocurrency frauds, and legal support services to other law firms as Off Counsel.
We believe in a personalized approach to legal matters. That’s why we assign a single lawyer to each case.

This ensures we fully understand your legal needs and can tailor our strategy to your specific situation.

Our philosophy is based on individual attention and commitment, providing you with the best possible outcome for every case.

    Our Legal Services

    Criminal Law in Spain
    We handle all types of criminal proceedings, with special attention to economic crimes, offenses against the Public Administration, drug trafficking and unjust accusations that may involve serious precautionary measures such as pre-trial detention. We offer criminal defense with effective legal advice in complex cases at the national level from the beginning of the procedure.
    Compensation for Wrongful Pre-trial Detention
    We fight for justice and compensation by defending the right to be compensated after having suffered unjust deprivation of liberty, having been acquitted or the case dismissed. We study each case of pre-trial detention that has ended without conviction to claim financial compensation before the Ministry of Justice, focusing on laws and legal practice in Europe.
    Collective Claims
    We represent individuals affected by international scams, frauds related to cryptocurrencies, failed investments, or deceptive business projects. We organize the joint defense of those affected to maximize legal impact, whether through criminal, civil, or administrative channels, in Spain or before international authorities, guiding you through complex legal processes and defending your interests.
    Strategic Legal Support
    We offer an Off Counsel service to provide specialized legal advice to law firms, companies, and professionals requiring strategic support in complex areas of law, such as Economic Criminal Law, Drug Trafficking Offenses, and Organized Crime in Spain. Our multidisciplinary team brings experience, personalized solutions, and absolute confidentiality, strengthening your legal capacity in highly complex cases with national and international scope.
    Medical Claims Due to Failures in the Public Health System
    We advise patients who have suffered harm due to serious deficiencies in public healthcare: from unjustified delays in ambulance arrivals or in emergency services, to excessive waiting lists that force them to resort to private healthcare to access essential operations or treatments. We analyze each case to claim the expenses paid and demand compensation for the damages caused.
