We defend individuals, companies and institutions: their liberty, their assets, their dignity and their rights.
We come in before an investigation file exists, throughout the proceeding and after the sentence. From the compliance program that prevents the offense to the enforcement stage that returns liberty. Criminal law in full, from beginning to end.
They are the flag and the crest of this firm. Justice binds in both directions, to the person who was harmed and to the accused who should never have been. And no liberty holds without dignity, which is the first thing a criminal proceeding puts at risk.
OL Defensa practises criminal law exclusively, federal and state, from the first police act to the last appeal.
We take on a limited number of matters. Each is directed personally by the partner who signs it, through every stage and instance. And what is entrusted to this firm stays with this firm, once the matter closes and long after.
Seventeen years devoted to a single field, across all its branches and before every instance in the country.
The file of someone who cannot pay is prepared with the same rigour as the file of someone who can. Defence admits no categories.
What is entrusted to this firm is not discussed, is not cited and does not expire.
Expert witnesses, forensic accountants and investigators across the country. When the prosecution report fails, someone is there to take it apart in the hearing.
Before the FGR, its specialized prosecution units and the federal courts, at every stage.
View scope →The federal jurisdiction holds the country's most technically and institutionally demanding matters. There we represent individuals and companies before the Attorney General's Office, its specialized prosecution units and the federal courts, at every stage of the accusatory procedure.
We come in before an investigation file exists, while the process can still be avoided, and stay through constitutional relief before the Circuit Courts. One strategy, held without deviation at every procedural decision.
Before the prosecution offices and courts of all 32 states.
View scope →The National Code is one, but its application changes from state to state, and that difference is known by whoever litigates there every week. OL Defensa appears nationwide with lawyers, expert witnesses and investigators admitted in each jurisdiction.
The standard does not change with the address. Our own defensive investigation, strategy inside and outside the proceeding, and hearings prepared in advance in any of the 32 states.
Early-release benefits, incidental motions and rights in custody before the Enforcement Judge.
View scope →The sentence does not close the matter. Criminal enforcement is a jurisdiction of its own, with its own incidental motions, disputes and remedies, and it decides how long a person actually stays deprived of liberty.
We litigate early-release benefits, prison transfers and enforcement motions with the demands of any other stage. A sentence wrongly enforced is an unlawful sentence.
Defense of the legal entity (arts. 421 to 425 of the CNPP) and of its governing body.
View scope →When a criminal investigation reaches a company, the file is the smallest of the problems. Operations stall, credit lines are pulled and the shareholders start asking. Corporate defense handles the case and the business at the same time, or it is useless.
We represent the legal entity, whether accused or aggrieved, and its governing body. We coordinate with legal, tax and communications so the company keeps running while the proceeding advances.
Fraud, breach of trust, fraudulent management and dispossession.
View scope →Asset crimes are won on the underlying economic transaction, not on the criminal definition. Before arguing fraud or breach of trust, you have to reconstruct what was agreed, what was paid and what was documented.
We represent the person accused and also the person who lost the assets and wants them back. In both cases the work ends the same way, with the money where it lawfully belongs.
Tax fraud and Fiscal Code offenses before the SHCP, the SAT, the Fiscal Attorney's Office and the UIF.
View scope →Very few lawyers command tax law and criminal law at once, and without both there is no possible defense against a tax file. We represent individuals, companies and corporate groups when the Ministry of Finance, the Fiscal Attorney's Office, the SAT, the specialized prosecution units and the Financial Intelligence Unit act as a block on the same matter.
We challenge the audit, dismantle the expert report and review the quantification of the loss piece by piece. This is the ground where the firm litigates its largest matters.
Banking and securities offenses before the CNBV, under the Credit Institutions Act and the Securities Market Act.
View scope →In the financial system, the line between an aggressive transaction and an offense is drawn by a technical detail. Defending there requires knowing the criminal definition as well as the logic of the market and its regulation.
We appear before the financial authorities with teams that combine criminal litigation and specialized expert analysis, and we establish the lawfulness of every questioned transaction with the evidence that supports it.
Money laundering (art. 400 Bis of the CPF) and asset seizure, before the UIF of the SHCP.
View scope →Laundering does not stand on its own. It needs a predicate offense the funds supposedly come from, and that is where the charge breaks. We work on that chain while protecting the assets from seizure and precautionary measures.
We handle matters of tax and financial origin before the Financial Intelligence Unit and the Attorney General's Office. A charge under art. 400 Bis freezes accounts, contracts and reputation long before any judgment exists.
Challenges to SAT audits and assessments before the TFJA, before any criminal case exists.
View scope →The best tax-crime defense is usually fought where there is still no criminal matter. We challenge the audit, contest the assessment and litigate before the Federal Court of Administrative Justice while the matter remains administrative.
Settled there, it never reaches the prosecution. It is the cheapest intervention for the client and the one that leaves the least trace on their name.
Acts of corruption under Title Ten of the CPF, before the Specialized Prosecutor's Office, the ASF and the UIF.
View scope →A corruption investigation is litigated on four planes at once, the criminal, the administrative, the institutional and the press. Neglecting one costs as much as losing the file.
We represent clients before all three levels of government with a strategy that covers the file and the context. On the preventive side we design the integrity policies and protocols that reduce the organization's exposure before anyone asks.
Embezzlement, bribery, abuse of authority and improper use of powers.
View scope →Public office carries a criminal exposure no other occupation has. We defend serving and former public officials against charges arising from their post, with the technique and the discretion these matters impose.
We have handled matters involving figures of high institutional exposure, where every filing is read outside the file and a poorly prepared hearing has consequences beyond the client.
Compliance and due diligence (LFPIORPI) against the criminal liability of the legal entity.
View scope →The best criminal matter is the one that never comes to exist. We design and implement compliance, integrity and governance programs that reduce the organization's criminal risk and evidence its due diligence before the authorities.
A solid program is not a document filed in a drawer. It is the evidence that, on the day it matters, separates the company and its directors from criminal liability.
Diagnosis of criminal and corporate risk before it materializes.
View scope →We audit operations to locate the breaches, the vulnerabilities and the criminal exposure that has not yet detonated. The deliverable is an action plan with owners and deadlines.
Knowing precisely where the risk sits is what allows you to decide before the authority decides for you.
Forensic audit and accounting expert evidence that carry the defense on technical proof.
View scope →In economic crimes, whoever explains the numbers better wins. Our forensic team traces assets, reconstructs transactions and issues accounting expert reports built to survive cross-examination.
We translate the books into a verifiable explanation, whether to detect an internal risk or to establish in court that the transaction was lawful.
Active and passive extradition under treaty, and defense of foreign nationals in Mexico.
View scope →Extradition is litigated on the ground of treaty law, where the applicable treaty and the international standard weigh more than the originating file. We act in active and passive extradition with a single objective, that the client does not leave the country.
We also represent foreign nationals in criminal proceedings in Mexico, activating their consular rights and treaty guarantees from the first hour.
Representation of victims before the Specialized Prosecutor's Office for Violence against Women.
View scope →We represent women, girls, boys, adolescents and people in situations of vulnerability against violence, abuse and exploitation. The first step is usually a protection order, and it is usually urgent.
Gender-based litigation is a methodology, not a statement of principles. It orders the strategy around the victim's safety and dignity, including the confidentiality of their identity where the law requires it.
A national network of criminal lawyers under a single strategic direction.
View scope →No firm litigates with equal command in all 32 states. Acknowledging that is what makes it solvable. OL Defensa coordinates a network of local criminal lawyers, experts and investigators who bring knowledge of the ground where the matter opens.
The client gets the same standard anywhere in the country, with a single strategic direction and a single point of contact.
Recognition of innocence (art. 486 of the CNPP) where the evidence supports it.
View scope →We take on matters where reviewing the evidence shows the convicted person did not do it. We go back to the complete file, reconstruct the facts and locate the error, the omission or the irregularity the proceeding let through.
Returning liberty to someone who should never have lost it is the reason this profession exists.
The same defense, without the client's means changing the standard.
View scope →OL Defensa takes pro bono causes with the rigor and dedication of any other matter. The file is prepared the same, litigated the same and appealed the same.
We represent people without means against arbitrary detentions and unjust proceedings. Access to justice is a right, and where it does not reach on its own, someone has to carry it there.
Runs the firm's cases. Litigates in state and federal jurisdictions, with favorable rulings in hydrocarbons, kidnapping and organized-crime files.
Trained within the accusatory system, not adapted to it. His ground is the hearings in the matters others hand back, in hydrocarbons, kidnapping and drug-dealing, in both state and federal jurisdictions.
His record in those files includes non-binding orders and less restrictive precautionary measures obtained in highly complex matters.
The Direction entrusted him with running the cases for a concrete reason. He prepares every hearing down to the detail and knows when a matter is won by litigating and when it is won at the table.
Runs the firm's cases alongside the Direction. Designs the complex defense strategies and assesses every file in terms of scenarios and probability.
He works the complex defense strategies and the doctrine of offenses of recent construction. Every move in the case is decided with three scenarios already run.
He has a second discipline uncommon among criminal lawyers. He trades financial markets, exchange and over-the-counter, with quantitative risk modeling.
That is where his way of reading a file comes from, measuring volatility and probability before deciding. It is what makes him useful in the contingencies where an error cannot be corrected.
Specialists in hearings, case theory and cross-examination, with national and international training.
Forensic and technical support that delivers evidence able to stand up at trial.
Specialists in economic and tax criminal matters for the analysis of audits and expert opinions.
Local criminal lawyers accredited across all 32 states, coordinated under one direction.
Every member operates under an unbreakable commitment to loyalty and discretion.
At the Escuela Libre de Derecho, to teach is to break the bindings of the mind and urge it to exercise its own strength, trusting it and loving it, as the bird trusts its wings and loves them, willing servants of its own will and sure guarantors of its freedom.
There are defenses that allow no second attempt. When a person's liberty, assets or name are decided in a single move, everything depends on who directs the strategy. For more than seventeen years that direction has been Oscar Ortega Guerra's, on the side of the one the State singles out and in the matters where losing is not an option and discretion weighs as much as the result.
His ground is the entire criminal field. From high-value tax crime in the billions to organized crime, from corporate fraud to international extradition and hydrocarbon offenses. Few attorneys cover that spectrum. Fewer still direct it personally, across every stage and before every instance, from the first proceeding to the last remedy.
But what defines his defense is not only what he commands, but how and when he intervenes: from before an investigation file even exists, anticipating the risk; and on every front at once, not just the procedural one. He prepares every matter down to the last detail and leads the strategy with absolute control. He leaves nothing to chance, because his clients cannot afford to.
"In seventeen years no client has ever had to wonder whose side his lawyer was on."
Each one arrived with a person, an estate or a company behind it. The file was the manageable part.
The officer's liberty, the group's assets and the continuity of operations, all hanging on an accounting report that could turn into pre-trial detention.
We challenged the Large Taxpayers report line by line, dismantled the quantification of the loss and coordinated the defense against four authorities acting as a block, on the criminal, tax and asset fronts at once.
A matter this size reaches the banks, the suppliers and the families living off the payroll. While the file was being litigated, the operation had to be kept standing.
Active defense. Charge contained and operations protected throughout.
A charge under art. 400 Bis before the anti-laundering prosecutor reaches liberty, accounts, assets and the very possibility of continuing to operate.
We entered at the investigation stage and attacked the core of the offense, the predicate crime the funds supposedly came from, while establishing the lawful origin of each transaction.
Laundering contaminates what it touches. Before any judgment exists there are frozen accounts, cancelled contracts and banks that stop returning calls. That front is handled in parallel or the client wins the case and loses the company.
Defense at investigation stage, built on the absence of a predicate offense.
It was not one station, it was the whole group. Its operations, its permits, its officers and its name, against an investigation for dispatching a volume different from what it invoiced.
We took on representation from the raid onward. We worked on two planes, the lawfulness of the search, the seizure and the chain of custody on one side, and the substance of the commercialization on the other. We filed, on an extra-urgent basis, the protection of rights and the lifting of the seizure before the District Judge.
A seized station stops the cash flow of the entire group. Every day of closure is payroll, credit and permits at risk, and that runs far faster than the proceeding.
Lifting petitions filed and operations restarted without reaching court.
An ASF complaint drags along the career, the liberty, the disqualification and the public name, all at once.
We built the defense at investigation stage, before any proceeding existed, with analysis of the complete file to defuse the charge of improper use of powers and fraud before it reached a judge.
Winning in court leaves a trace. Never being charged leaves the file closed and the career intact, which was exactly what the client came to protect.
DECISION NOT TO PROSECUTE. No court proceeding.
The client's public honor, his liberty and the peace of a family that was also being named.
We litigated before the anti-corruption prosecutor on the twin dimensions of embezzlement and laundering, submitting every investigative act to judicial control.
In high-profile matters the press sets its own calendar. The client and his circle had to be shielded while the file advanced on another.
Active defense, with hearings before the Control Judge.
The system's heaviest offense, with communications intercepts, telephone analysis and extradition in the background.
We aimed the strategy at contesting the lawfulness and evidentiary reach of the communications intercepts and the investigation reports, obtained consular assistance for the foreign national and coordinated the defense of several co-defendants in a single hearing.
With a foreign national involved, the initial hearing decides more than pre-trial detention. It decides whether an extradition starts running.
Defense at the initial hearing, attacking the lawfulness of the evidence.
The money had already left. Establishing the fraud was the manageable part; following the trail of the transfers, the hard one.
We represented the aggrieved party with tracing of the transfers and a strategy directed at asset recovery and at the liability of the managers.
Here the outcome is not measured in judgments. Every step is measured in how much of the estate comes back and how much of the institution's standing is preserved.
Active complaint and joinder, aimed at recovery.
One person's liberty and a family's integrity, decided in hours, with judicial intercepts and the specialized unit in operation.
We acted with technique and composure under the simultaneous pressure of the file and the crisis, guarding every step before the specialized unit and standing with the family at each decision.
A family in shock makes irreversible decisions in minutes. A good part of the work was keeping any of those decisions out of the file.
Intervention at the initial hearing.
The criminal liability of the legal entity, a silent risk that without prevention detonates into a charge reaching the whole organization.
We designed the risk analysis, the detection of vulnerabilities and the allocation of responsibility by structure, with an executive report for the governing body to decide on.
The day the request for information arrives, that program stops being a cost and becomes the documentary proof of the company's due diligence.
Corporate prevention report and executive summary delivered.
The victim's immediate safety and, where applicable, the best interests of the child, neither of which admits delay.
We obtained emergency protection orders under the standard of the Belém do Pará Convention and the duty of due diligence, with litigation guided by gender and child perspective.
A protection order takes hours to issue and years to repair if it arrives late. Identity confidentiality is handled from the first filing, not once the name is already circulating.
Protection measures obtained. Representation with identity withheld.
The client's name, liberty and family stability, in a matter under public scrutiny.
We built the defense on due process and the principle of congruence, and answered the prosecution's and the adhering party's grounds until the ruling was confirmed on appeal.
Winning at first instance and losing on appeal returns the client to the starting point a year older. A ruling only counts once it is final.
NON-BINDING ORDER, confirmed on appeal.
Liberty, from the first minute. Federal weapons offenses escalate fast and pre-trial detention arrives before any analysis does.
We came in at the seizure, concentrating the work on the lawfulness of the arrest, on the chain of custody and on whether the elements of the offense were met at all.
Between facing the proceeding at liberty or from custody there is a difference that cannot be recovered later. That difference is played out in the first forty-eight hours.
Defense at investigation stage, attacking the lawfulness of the seizure.
Liberty and assets, against an accounting expert report and a banking institution with all its weight behind it.
We worked on the accounting report, the traceability of the transactions and the substantiation of each claim, reconstructing dozens of movements.
A bank does not litigate with lawyers alone, it litigates with its entire audit department. Matching that technical capacity is the condition for the defense to exist at all.
Documented intervention in the financial file.
There was no charge yet, but there was a real risk to the operation and to the company's standing.
We came in at the first request for information, handling what was asked, protecting the company's position and anticipating any escalation.
The answer given to a request for information is the one someone will read aloud in a hearing two years from now. It is drafted with that day in mind.
Representation of the legal entity from the information-request stage.
The liberty of a foreign national far from home, with every consular and treaty guarantee in play.
We activated his consular rights and built the defense with independent experts in digital and forensic criminalistics, who contributed scientific evidence of our own to support the case theory.
Without independent expert evidence, the only technical account in the file is the prosecution's. Putting a second one on the table changes the ground of the hearing entirely.
Defense supported by independent expert evidence.
Liberty during the proceeding, which today depends on constitutional criteria still in motion.
We study and apply the most recent Supreme Court case law to support less restrictive precautionary measures and our clients' liberty during the proceeding.
A ruling published three weeks ago can get someone out of pre-trial detention. Only if the defense lawyer read it in time.
Criterion applied across matters of liberty and tax-criminal exposure.
It is not six prosecution offices: it is fourteen administrative units and more than fifty special offices. Each builds the file its own way.

«Over seventeen years of practice. No client betrayed. No cause abandoned. No secret revealed.»
Ten brief answers to the questions that come up again and again. None of them replaces an assessment of the specific case.
Do not attend alone and do not testify without technical defence. Appearing without counsel allows whatever you say to enter the file and be used against you. A summons does not compel testimony: article 20 of the Constitution recognises the right to remain silent. The first step is to review the investigation file and decide whether, when and in what terms to testify.
Article 19 of the Constitution imposes it for, among others, organised crime, intentional homicide, femicide, rape, kidnapping, human trafficking, hydrocarbon offences, serious tax offences such as tax fraud and the use of sham invoices, and money laundering. In those cases the person is held before any judgment, so the defence is won or lost in the first hours.
Fees depend on the procedural stage, technical complexity and jurisdiction. At OL Defensa the first assessment conversation is free and commits you to nothing: its purpose is to tell you exactly what you are facing and what defence it requires.
It is the ruling by which the supervisory judge finds that the prosecutor’s evidence is insufficient to establish that an offence occurred or the defendant’s probable participation. It closes the proceedings at that stage and is one of the best possible outcomes at the initial hearing.
The FGR and the prosecution services of all 32 states, and by way of complaint the SAT, the Federal Tax Attorney, the UIF, the Federal Audit Office, PROFEPA, COFEPRIS, PROFECO, the CNBV and IMPI, among others. Since the amendment to article 421 of the National Code of Criminal Procedure, the company answers independently of the individual.
In all 32 states, through Alianza Penal: a network of local criminal lawyers coordinated under a single strategic direction, so the matter is litigated with knowledge of the local forum without losing the unity of the defence.
It is practice dedicated exclusively to criminal law, across all its branches and before every instance, as opposed to the generalist who handles criminal matters among others. It requires command of the adversarial system, the theory of the case, cross-examination and defence expert evidence.
Yes. The victim is a party to adversarial criminal proceedings and may appear as legal adviser, offer evidence, examine witnesses and appeal. OL Defensa takes both positions at the table: defending the person the State accuses and representing the person who was harmed.
It is a procedure autonomous from the criminal case by which the State claims ownership of assets linked to certain offences, without any need for a conviction. It is contested by proving the lawful origin of the asset and the owner’s good faith, with documentary and accounting evidence from the outset.
It is the set of policies and controls proving that the company did what it should to prevent the offence. Under articles 421 to 425 of the National Code of Criminal Procedure, a suitable and effectively implemented programme can mitigate or exclude the company’s criminal liability.
