SPECIALIST AREAS

Criminal law

You have the right to receive effective assistance from a lawyer from the onset of any criminal proceedings.

The LENTZ-LEHNEN team will assist and defend you:

Whether you are

  • the alleged perpetrator of reprehensible actions;
  • in pre-trial custody;
  • the accused or defendant in an ongoing criminal case;
  • summoned before the Police, the Investigating Judge or before the criminal courts (Police Court, District Court of Luxembourg and Diekirch, whether before a criminal or correctional chamber, Court of Appeal, Court of Cassation).

Whether it concerns common law offences, such as

  • harm to persons, such as homicide, assault and battery, accidents, etc.;
  • damage to property, such as theft, destruction, fraud, etc.;
  • traffic violations, such as temporary withdrawal of a driving licence, withdrawal of a driving licence by the administrative authorities, seizure of vehicles, etc.;
  • specific violations in terms of business law, such as abuse of company assets, money laundering, etc.

Or whether you are

  • a victim of an assault or damage caused by others and you wish to file a complaint;
  • a victim and wish to obtain compensation for your personal injury and material damage (civil proceedings or direct summons).

We allow you to establish your defence or compensation case. Moreover, we will make an appointment in order to review your questions and set out an effective and necessary strategy.

Divorce and family law

Are in the process of separating and want to know the consequences of a separation. Moreover, you wish to plan ahead in order to protect your personal interests?

Do you want to safeguard the interests and well-being of your children?

The team at the LENTZ-LEHNEN law firm will advise with regard to the preparation of your case and the adoption of the appropriate strategy (family mediation, family court) in your particular case:

  • determining the right of access and accommodation;
  • domestic violence;
    • actions to resolve or contest paternity;

Inheritance law and donations

The transfer of property through inheritance or by way of a gift can give rise to a number of questions regarding both the possible means of transfer (wills, donations, sharing among ascendants, etc.) and the associated costs (notary fees, registration costs, contributions, etc.).

Similarly, after a person's death, the transfer of his or her assets to the heirs can be complex due to the various participants involved in the process, such as a notary, court, legal expert, etc.

The LENTZ-LEHNEN law firm will provide efficient solutions in accordance with your intentions and needs. Similarly, we are on hand to defend your interests in the event of litigation before a court of law.

The rights of children and adolescents

Similarly, after a person's death, the transfer of his or her assets to the heirs can be complex due to the various participants involved in the process, such as a notary, court, legal expert, etc.

The LENTZ-LEHNEN law firm will provide efficient solutions in accordance with your intentions and needs. Similarly, we are on hand to defend your interests in the event of litigation before a court of law.

  • liability in matters of construction (legal expertise, construction defects, faults, guarantees, etc.);

  • enforcement of national and international decisions;

  • applications for bankruptcy or judicial liquidation;

Social security law

The services provided by the Social Security authorities (CNS, AAA, CNAP, ADEM, FNS, Dependency) in Luxembourg are broad in their scope and may appear complex in nature.

The LENTZ-LEHNEN law firm will guide you in your efforts to assert your rights with the Social Security authorities in accordance with your specific situation (illness, work accident, internal or external redeployment, disability, etc.).

Labour law

Labour law is subject to varying interpretations in an ever-changing legal environment.

The LENTZ-LEHNEN law firm will advise you:

  • in the drafting employment contracts;
  • in specific situations (temporary work, seasonal work, etc.);

  • or at the end of the employment relationship (dismissal, resignation, etc.);
  • or in the context of collective bargaining relations (staff delegates, hours of credit, etc.).

Moreover, lawyers from the LENTZ-LEHNEN law firm will represent you before labour courts in the event of legal disputes (Labour Tribunal, Court of Appeal, Court of Cassation).

Human rights

Human rights are the fundamental rights and freedoms of every individual. As these human rights are the inalienable rights of all human beings, the LENTZ-LEHNEN law firm will help you to assert your rights without discrimination and on an equal footing in order to respect the guiding principle contained in Article 1 of the Universal Declaration of Human Rights: “All human beings are born free and equal in dignity and rights”.

We shall ensure that your rights are protected and respected, as established in various documents, in particular:

  • Universal Declaration of Human Rights of 1948;
  • Convention for the Protection of Human Rights and Fundamental Freedoms of 1950;
  • International Convention on the Rights of the Child of 1989;
  • and various other texts.

Final appeals

The aim of an appeal in cassation is not to have a case re-tried; the role of the Cassation court is to ensure the precise application of the rules of law by the respective courts and tribunals.

Our team shall advise you regarding the outcome of the decisions emanating from the courts of first instance and the Court of Appeal, in both criminal and civil cases. We will prepare the final appeals and draw up the necessary briefs.
