The practice
Advising and defending
Alexis Guillaume
Avocat à la Cour · Luxembourg Bar
Maître Guillaume advises and represents companies, directors and individuals facing a dispute, or a situation liable to become one.
The firm acts principally in civil, commercial, employment, criminal and administrative litigation — whether to bring a claim, to respond to proceedings, to challenge a decision, to obtain urgent relief, or to reach a settlement where the client's interests so require.
Its involvement often begins before trial. A formal notice, a terminated contract, a disagreement between partners, a decision by an employer or by an authority may shape the outcome of a matter long before a judge is seized of it.
The firm accompanies its clients through each of these stages, from negotiation to court proceedings, and also in the drafting and performance of their agreements.
Areas
Practice areas
Before the Luxembourg courts and in arbitration alike.
01 Civil and commercial litigation Contracts, liability, urgent relief
Litigation is at the heart of the firm's practice. The firm represents clients in disputes arising from the performance or termination of a contract, from a liability claim, or from a disagreement between commercial partners.
Urgency often dictates the first decision: interim relief, an application without notice, a protective measure. From the first discussion the firm assesses whether such a step is needed to preserve your position while the substance is prepared.
02 Employment law Dismissal, clauses, Labour Tribunal
The firm acts for employers and for employees — never for both in the same matter. Dismissal, challenges to stated grounds, non-compete clauses, harassment, negotiated termination: the field is technical and its time limits are short.
The period for challenging a dismissal is particularly brief. If you have received a termination letter, the first thing to tell the firm is its date.
03 Leases and real estate Leases, co-ownership, construction
Residential and commercial leases, rent review, notice to quit, arrears, return of deposits. The firm also handles co-ownership disputes, neighbour disputes and construction defects.
04 Criminal law and white-collar crime Investigation, examination, defence
Assistance from the preliminary investigation onwards, support during judicial examination, defence before the trial courts. The firm acts for individuals and for companies under investigation.
The firm also assists injured parties seeking compensation as civil claimants in criminal proceedings.
05 Debt recovery Formal notice, attachment, enforcement
From formal notice through to attachment, the firm conducts the recovery of unpaid debts. Where a debt is certain and due, simplified procedures will often secure an enforceable title within a reasonable time.
06 Administrative law Review, permits, residence
Informal and contentious challenges to decisions of the administration: permits, sanctions, refusals, questions of residence and establishment. The firm represents clients before the administrative courts.
07 Family law Divorce, maintenance, contact rights, custody
Divorce by mutual consent or on the ground of irretrievable breakdown, judicial separation, winding up of the matrimonial regime. The field touches on what clients hold most private: it calls for as much restraint as rigour.
Where children are concerned, parental authority, residence, contact and accommodation rights and maintenance are best settled by agreement. Failing that, the family judge decides, and the file is then prepared like any other contentious matter.
08 Road traffic law Licence, suspension, speeding, drink-driving
The firm assists drivers facing proceedings that affect their right to drive in Luxembourg: immediate withdrawal of the licence, administrative suspension, a driving ban imposed by a court, or prosecution before the criminal courts.
A single offence may open two parallel proceedings — one criminal before the judge, one administrative before the competent authority — each with its own rules, time limits and remedies. Losing a licence often means losing access to work, so the firm looks first at what can be secured quickly.
