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.
  • Cybercrimes
    We fight for digital justice and the application of law in a technological environment. We defend and advise in cases involving online scams, hacking, identity theft, and cryptocurrency fraud.
    We study each cybercrime case with technical and legal rigor, analyzing the traceability of information and the validity of electronic evidence to ensure an effective legal response in accordance with international law and judicial and police practice.
  • 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.
