Luxembourg City is small but extremely internationally oriented — professional services are generally available in multiple languages (French, German, English at minimum). However, many official processes (court documents, administrative letters, formal legal acts) are conducted in Luxembourgish, French, or German — never assume English. When engaging any professional for official matters, confirm their language capabilities upfront. For legal matters involving Luxembourgish authorities, French is the most practical language for communication. Always check professional registration with the relevant professional body or supervisory authority (barreau, OEC, CSSF) before engaging services involving significant financial or legal decisions.
Language options: Luxembourg professionals routinely work in French, German, and English. Most lawyers, accountants, and financial advisors serving the international community work comfortably in English. Official legal documents (court orders, notarial acts, company articles) are in French or German. Tax communications from the ACD are typically in French. Notarial acts are always in French or German. Medical services: French-speaking doctors predominate, with German-speaking and English-speaking doctors available — specify your language preference when choosing a GP.
Lawyer / Notary (Avocat / Notaire)
Avocat: €150–400/hour for standard legal advice. Senior partner rates at international firms: €400–800/hour. Notary (notaire) fees are set by law (tarif légal): typically 1–2% of property value for real estate transactions, €75–250 for simple acts. How to find: Barreau de Luxembourg (barreau.lu) lists all registered avocat (lawyers). Chambre des Notaires (notariat.lu) for notaries. Many law firms in Luxembourg City operate in multiple languages (French, German, English, Luxembourgish). Referrals from employer HR or expatriate community groups. International law firm directories (Chambers & Partners, Legal 500) for senior business law.

💡 Notaries (notaires) are required for all property transactions, company incorporations, and certain legal acts in Luxembourg. Their fees are state-regulated and non-negotiable. For immigration and employment law (the most common needs for new expats), the Barreau directory is the best starting point. Many large employers have legal assistance programs or will refer you to their corporate lawyers for employment issues.
Accountant / Fiduciaire
Tax declaration preparation: €200–600 for employed individuals. Self-employed accounting package: €150–500/month. Fiduciaire services for SARL: €500–2,000/month including bookkeeping and payroll. How to find: IRE (Institut des Réviseurs d'Entreprises) for certified auditors. OEC (Ordre des Experts-Comptables) for accountants. "Fiduciaire" is the Luxembourg term for accounting/administrative services companies — very common for SMEs and individuals. Search fiduciaires at guichet.lu or through Chamber of Commerce directories.

💡 For employed individuals with straightforward taxes, professional help may not be necessary — the ACD's free tax assistance service (Büro der Unentgeltlichen Rechtsauskunft) helps with basic declarations. For self-employed, multiple employers, non-resident (frontalier) tax situations, or any investment income, a fiduciaire is strongly recommended. Luxembourg's tax system, especially the class system and impatriate regime, rewards professional advice.
Employment lawyer / Labour adviser
€150–400/hour. Fixed-fee employment contract review: €300–600. Wrongful dismissal representation: €2,000–8,000. How to find: Barreau de Luxembourg (barreau.lu) — search by "droit du travail" specialisation. Chambre des Salariés (CSL — csl.lu) provides free employment law advice to private-sector employees. ADEM (Agence pour le Développement de l'Emploi — adem.lu) provides employment guidance and handles redundancy notifications.
Barreau de Luxembourg (barreau.lu)Chambre des Salariés (CSL — csl.lu)
💡 Chambre des Salariés (CSL) provides free employment law advice to private-sector employees — worth consulting before paying for a lawyer. Luxembourg's Labour Code provides strong protection including mandatory notice periods, statutory severance, and end-of-year bonus rules. For conflicts with a public-sector employer, the Chambre des Fonctionnaires is the equivalent resource.
Estate Agent (Agent immobilier)
Agency fees for rentals: typically 1 month's rent as agency commission (paid by tenant) plus 17% VAT. For property purchases: typically 2–3% of purchase price agency fee (paid by buyer) plus 17% VAT. These are significant costs on top of already very high rental and purchase prices. How to find: CIL (Chambre Immobilière du Luxembourg) lists all licensed estate agents. Major agencies: Nexvia, Cushman & Wakefield, CBRE Luxembourg, Engel & Völkers, Savills, local agencies on athome.lu and immotop.lu. LinkedIn and expat groups for private recommendations.
💡 The Luxembourg property market is extremely tight — listings disappear within days. Act immediately when you find a suitable property. For rentals, having all documents ready (proof of income, employment contract, numéro national, bank statements, ID) in one folder means you can submit a rental application same day. Some agents require months of rent in advance as a security deposit — know the legal maximum.
Independent Financial Advisor
Fee-based advisors: €100–300/hour consultation. Commission-based (check conflict of interest). Wealth management: typically 0.5–1.5% of assets under management annually. How to find: CSSF (Commission de Surveillance du Secteur Financier — cssf.lu) maintains a register of licensed financial advisors and investment firms. International advisors catering to expats: Blacktower Financial Management, deVere Group, Expat Wealth Management Luxembourg. Belgian and German cross-border financial advisors familiar with Luxembourg tax rules.
💡 Independent financial advice is particularly valuable in Luxembourg for managing the complex intersection of impatriate tax regime, cross-border pension planning, investment fund structuring (Luxembourg is home to the world's second largest fund industry after the USA), and estate planning. Always verify CSSF registration before engaging any financial advisor.
Relocation Service
Full relocation package: employer-covered in many international organisations. Private arrangement: €1,500–5,000 for home search assistance and settling-in services. How to find: Many large Luxembourg employers (especially EU institutions and financial firms) offer or subsidise relocation services for new international staff. Private relocation companies: Crown Relocations, Santa Fe Relocation, Gosselin Moving. Expat-focused services advertised in Expats in Luxembourg groups.
💡 If your employer is not providing relocation assistance, a good relocation consultant can be invaluable for navigating Luxembourg's ultra-competitive housing market, commune registration, and initial administrative tasks. Ask your employer explicitly whether any relocation support is available.
