Profile & Background

A cross-disciplinary approach

A legal situation may involve several areas simultaneously. KM Legal analyzes the interactions between Employment & Labor Law, Corporate Law & Business Law, Immigration & International Mobility, Social Security & Cross-Border Rights and taxation to develop a coherent overall response.

Direct support

Each case is addressed in its real-world context, with particular attention paid to the legal, professional, and human stakes. The options are explained clearly to allow the client to understand the risks, priorities, and consequences of each decision.

Advise, negotiate, defend

KM Legal intervenes early to secure a decision or transaction, supports negotiations when a solution can be found, and safeguards its clients' interests should litigation become necessary.

KM Legal — A comprehensive approach for legal challenges that are rarely isolated

A cross-disciplinary approach for legal challenges that are seldom isolated

KM Legal supports companies, executives, employees, and individuals facing situations where multiple legal issues may intersect. The firm provides both advisory and litigation services, with particular attention to the tangible consequences of each decision.

Understanding the entire case file

A difficulty in Employment & Labor Law may have repercussions on the status of a foreign employee, their mobility, their social affiliation, or on a company's situation. Similarly, a reorganization, a company formation, or a governance decision can raise several legal issues at once.

KM Legal addresses each case in its entirety to identify the interactions between the different areas and to prevent a decision made on one matter from causing issues in another.

A practice structured around complementary skills

The firm operates in six areas that address different, yet often interconnected, needs: Employment & Labor Law, Immigration & International Mobility, Social Security & Cross-Border Rights, advisory and litigation, Corporate Law & Business Law.

This structure allows for supporting not only a company that needs to secure a decision, but also an executive, employee, or mobility professional faced with a complex individual situation.

  • Employment & Labor Law — supporting the employment relationship, preventing risks, and intervening when a dispute arises.
  • Immigration&International Mobility — assist in professional situations involving multiple countries or statuses.
  • Social Security & Cross-Border Rights&disputes — analyze the applicable rights, secure the procedures, and defend the client's interests when necessary.
  • Corporate Law & Business Law — structure, organize, and secure the key stages in a company’s lifecycle.

KM Legal assists companies, business leaders, employees, self‐employed professionals, and individuals in Luxembourg, as well as an international clientele facing challenges related to employment, business, or professional mobility.
The firm primarily practices in Employment & Labor Law, Immigration, International Mobility, Social Security & Cross-Border Rights, advisory and litigation, as well as in Corporate Law & Business Law. These fields are often interrelated and may be addressed jointly depending on the situation.
Because a legal case is not always confined to a single area. For example, an international recruitment may simultaneously raise issues regarding employment contracts, residence permits, social security, and mobility. Therefore, the analysis covers the entire situation.
The initial consultation allows us to understand the facts, priorities, and any deadlines. KM Legal can then outline the potential steps, detail the necessary information or documents, and define the scope within which the firm can operate.
No. A significant part of the practice involves proactive measures: securing a decision, drafting or negotiating a document, supporting a transaction, or identifying a risk. When a dispute is already present, the firm can also engage in negotiations and litigation.
