Introduction: Why Law Firm Websites Require Special Legal Attention

A law firm website is not merely a business card — it is a legal document subject to multiple overlapping regulatory frameworks simultaneously. A firm must satisfy requirements of commercial law (disclosure obligations), professional regulations (deontological requirements), data protection law (GDPR), and consumer law (electronic services). Failure to meet even one of these requirements exposes the firm to disciplinary and administrative sanctions.

This guide covers requirements for four key EU jurisdictions. Each has its own legal and professional specifics that firms should address in their website structure.

Poland: Compliance Checklist for Law Firms

Polish law firms (adwokackie and radcowskie) are simultaneously subject to the Electronic Services Act, professional regulations, and GDPR.

• NIP and REGON: Firms operating as sole traders or companies must provide their tax identification number (NIP). Companies registered in the KRS must provide the KRS number under Art. 7 of the KRS Act.
• Bar registration number: Every advocate (adwokat) and legal counsel (radca prawny) must provide their registration number on the list maintained by the relevant bar (Okręgowa Rada Adwokacka or Okręgowa Izba Radców Prawnych).
• Professional liability insurance (OC): Information about professional indemnity insurance — required by the Code of Advocate Ethics and OIRP regulations.
• Registered address: Full office address — required by the Electronic Services Act (Art. 5(2)(1)).
• Privacy policy and cookies: Required by GDPR and the Electronic Services Act. Must include legal basis for processing, retention periods, and data subject rights.
• Cookie banner: Required by the Telecommunications Law (Art. 173). Must make refusal of consent as easy as giving it.
• Company information: For companies — legal form, share capital (sp. z o.o.), KRS number, registered office, registration court.

Germany: Impressum and Requirements for Law Firms (Rechtsanwaltskanzlei)

Germany has some of Europe's most rigorous website disclosure requirements. A missing or incomplete Impressum is one of the most common reasons for legal warnings (Abmahnungen).

• Impressum (§ 5 TMG): Mandatory for all "geschäftsmäßig" (commercial) websites. Must include: full name or company name, address, email, and phone number.
• Berufsbezeichnung and bar chamber: Rechtsanwälte must state their professional title, the country of authorization, and the relevant Rechtsanwaltskammer.
• Berufsrechtliche Regelungen (BRAO): Reference to the Bundesrechtsanwaltsordnung and Berufsordnung der Rechtsanwälte (BORA) as applicable professional standards.
• Berufshaftpflichtversicherung: Name of insurer, registered office, and — if geographical scope is limited — a clear indication of that limitation (§ 51a BRAO).
• Umsatzsteuer-ID (VAT): VAT identification number for intra-EU transactions.
• Datenschutzerklärung (DSGVO): GDPR-compliant privacy policy including legal basis for processing, user rights, and DPO contact details (if required).
• Cookie-Banner: Required under TDDDG (formerly TTDSG) — cookie banners must meet the "eindeutige Einwilligung" (explicit consent) standard.

France: Mentions légales and Requirements for Law Firms (Cabinet d'avocats)

In France, the LCEN Act (Loi pour la confiance dans l'économie numérique) defines disclosure obligations for professionally operated websites.

• Mentions légales (Art. 6 LCEN): Must include: full name or company name, registered address, phone number, email, SIRET/SIREN number, VAT number.
• Ordre des avocats: Membership in the relevant Barreau, bar registration number, and principal's name (for trainees).
• Responsabilité civile professionnelle (RC pro): Professional indemnity insurance details per CNB (Conseil National des Barreaux) requirements.
• Directeur de la publication: Identification of the person responsible for website content (Art. 6(II) LCEN).
• Hébergeur: Hosting provider details (company name, address, phone number).
• Politique de confidentialité (RGPD): GDPR-compliant, covering processing of client and prospective client data.
• Bandeau cookies (CNIL): Cookie banner compliant with CNIL guidelines — required link to preferences management, refusal option as prominent as acceptance.

Spain: Aviso legal and Requirements for Law Firms (Despacho de abogados)

• Aviso legal (LSSI-CE Art. 10): Identifying information: name or trade name, address, NIF/CIF, email, telephone.
• Colegio de Abogados: Membership in the relevant Ilustre Colegio de Abogados, registration number (colegiado number).

• Cookies (LSSI-CE): Cookie policy with consent management mechanism meeting AEPD (Agencia Española de Protección de Datos) requirements.

Common GDPR Requirements for All EU Law Firms

Regardless of jurisdiction, all law firms processing personal data of clients (or prospective clients via contact forms) must ensure:

• A privacy policy with the legal basis for processing each data category.
• Information on data subject rights (Art. 13/14 GDPR).
• DPO contact details (if required) or the person responsible for data protection.
• Cookie consent mechanism meeting the "freely given, specific, informed and unambiguous" requirement (Art. 4(11) GDPR).
• Procedure for handling data subject requests (access, erasure, portability).
• Record of processing activities (Art. 30 GDPR) — an internal document, not published on the website, but required for inspection by the supervisory authority.

How to Automate Compliance Verification

Manual verification of dozens of legal requirements on a law firm website is time-consuming and error-prone. Automated compliance scanning tools such as Juralex Audit check for the presence of required elements (NIP, KRS number, Impressum, Mentions légales), analyze cookie banner configurations, and verify privacy policies — generating detailed reports with prioritized findings.
