Since its establishment in 1992, Gárdos Mosonyi Tomori became one of the market leaders in Hungary. Although the firm changed as new colleagues joined and as we started to provide new services, the basic principles of our firm remained the same: to provide the highest professional standards and a client-centric approach.

Our dynamic team, building on the decades of experience of the firm, provides full-scope legal services both to multinational and Hungarian companies from SMEs to medium and large undertakings. We are especially proud of the professional recognition in the field of banking, capital markets and insurance law.

The listings by the ranking directories, the appointments as arbitrators, and the invitations to teach at various Hungarian universities show that Gárdos Mosonyi Tomori is highly regarded on the market.

As an independent Hungarian law firm, we are not a member of an international law office. However, based on long-standing relationships with several international law offices, we can assist our clients in cases that require the knowledge of foreign legal expertise. Gárdos Mosonyi Tomori is a member of Advoc, a global network of more than 90 independent law firms with offices across more than 70 countries worldwide.

Gárdos Mosonyi Tomori Law Office is a leading player in the area of banking law, capital markets and insurance law. Having regard to the highly-harmonised EU financial market, clients from each corner of the continent turn to the firm. As Gárdos Mosonyi Tomori Law Office is a highly-recognised firm in the financial sector major financial institutions, investment firms and insurance companies carrying activity in Hungary are all among its clients. The Hungarian financial sector is closely connected to the EU market with market players providing cross-border services. Providing legal services therefore in relation to complex cross-border projects (e.g. securitisation, legal support of cross border service providers) is part of the daily business for the law office. Gárdos Mosonyi Tomori Law Office is often involved in complex EU-wide projects and provides legal support in respect of the Hungarian aspects of the projects (e.g. legal opinions on enforceability or company law matters).

Gárdos Mosonyi Tomori is the exclusive contributor of international organisations (eg ICMA), worldwide content aggregator services (eg Mondaq) and law firms (eg Latham & Watkins LLP) in relation to Hungarian regulation regarding banking law and capital markets.

Apart from the market players, the Law Office regularly provides legal services to Hungarian regulators and European institutions.

Although Gárdos Mosonyi Tomori Law Office is an independent Hungarian law firm but is also has its worldwide network of offices through its membership of ADVOC, the leading international network of independent law firms. Being a member of ADVOC, Gárdos Mosonyi Tomori Law Office can assist its clients in legal matters in 73 jurisdictions. Péter Gárdos is a member of the Board of Advoc Europe.

Being committed to a high professional standard in its primary activity does not prevent Gárdos Mosonyi Tomori Law Office from being socially responsible. As the members of the law office share a common view in terms of the protection of fundamental rights, the importance of social responsibility, education of future generation and work-life balance, they actively engage in various projects in order to make things better.

Gárdos Mosonyi Tomori Law Office continuously offers legal services to people or organisations who otherwise cannot afford to turn to lawyers. Such legal help is provided, eg for small municipalities who are in need of professional legal expertise. We provide them with legal advice in relation to property law issues, labour law issues or matters relating to contract law.

We were honoured that along with lawyers from other law firms, we could provide the Chance for Children Foundation with pro bono legal advice in a claim for damages on behalf of 75 gypsy children from Gyöngyöspata. These children were segregated in the primary school and the state denied giving them a remedy. It was a great achievement that based on our claim for the compensation of damages for the infringement of their personality rights, and for the loss of chance that occurred due to their segregation; both the court of first instance and the court of second instance awarded damages to the children.

Gárdos Mosonyi Tomori Law Office is devoted to the education of new generation of lawyers on various platforms. Members and lawyers of the law office therefore hold lectures at Eötvös Loránd University Faculty of Law, Pázmány Péter Catholic University and Corvinus University, at the Budapest Institute of Banking and at the International Training Center for Bankers. Besides that, regular seminars are held for market participants in order to ensure compliance with regulation and to share good practice in the market.

The Law Office shares the view that granting a healthy work-life balance is indispensable in today’s world. Colleagues are therefore encouraged to live with the option of flexible working conditions, including home-office, and parents who raise children are granted with the opportunity of part-time jobs.
