JM&W Abogados & Asesores has a broad team of lawyers, advisors and specialist collaborators with decades of accumulated experience across the widest range of legal fields. The firm offers the strength of a consolidated team and the personalised attention every client deserves.
JM&W Abogados & Asesores is a firm with a broad and consolidated professional structure, comprising lawyers, legal advisors, specialists across different branches of law and external collaborators of recognised standing. Every matter that reaches the firm is analysed with the depth and rigour that only a high-level multidisciplinary team can provide, where the accumulated experience and specialisation of each professional is placed at the client's service from the very first moment.
Our working model is collaborative: the most complex cases are handled with the joint involvement of several professionals, ensuring the greatest technical strength, the best procedural strategy and a swift, comprehensive response to any legal situation, whatever its nature or territorial scope.
Mauro Jordan de la Peña is a lawyer with over ten years of professional experience, specialised in proceedings of particular technical complexity, both at national and international level.
Throughout his career he has taken on the legal direction of numerous high-profile cases, developing a working methodology based on rigorous individual study of each matter and the construction of a solid line of defence, grounded in legal rigour and scrupulous respect for procedural guarantees and Fundamental Rights. His aim in acting before any court or tribunal is solely to provide the best possible legal service to those who place their trust in him.
He combines professional practice with academic research, having published notable works including "Actualidad Penal 2019" and "El representante procesal de la persona jurídica y los conflictos de intereses en el procedimiento penal español", both published by Tirant lo Blanch (Madrid).
Valeria Volovikova is a lawyer registered with the Madrid Bar Association, with a professional career oriented from the outset towards handling matters of singular legal and technical complexity.
She graduated in Law and Digital Law from Universidad CEU San Pablo (Madrid) and subsequently completed the Master's Degree in Access to the Bar at the Madrid Bar Association. She deepened her training with intensive specialisation in Economic Law, Compliance, Blockchain and Taxation, combining academic rigour with the practical vision of a lawyer working in an international legal environment.
From first contact to final resolution, Valeria personally accompanies every client in whatever they need: criminal proceedings, immigration and residence procedures, civil and family matters, tax issues, contracts, disputes with companies or public authorities — regardless of whether the matter is Spanish, Russian or international. Her command of Spanish and Russian, together with her knowledge of English, allows her to provide full-quality legal advice in complex cross-border matters.
For Russian-speaking clients living in Spain or with matters here, Valeria is the point of support that many seek and few find: a lawyer who fully understands their situation, speaks their language and knows both legal systems.
