German Company Name Search — Rules, Registers, and Checks

Why the Name Check Matters in Germany

A German company name (Firma) has legal effect the moment it is entered in the Handelsregister. Once registered, it cannot be challenged by a later applicant in the same Amtsgericht district — the first-come-first-served principle applies. A name that infringes an existing trademark can trigger injunctions from the trademark owner under §§14–15 MarkenG even after Handelsregister registration. Getting the name right before formation saves expensive correction costs and potential litigation.

• Handelsregister entry confers right to the Firma in the district — §§17, 30 HGB
• Trademark infringement under MarkenG §14 is independent of Handelsregister registration — both checks are required
• Name must be approved by the Notar and implicitly by the Amtsgericht clerk before entry
• Post-registration name change requires new notarial deed, shareholder resolution, and Handelsregister amendment — costs €800–€1,500
• IHK Firmenname advisory service provides a non-binding pre-clearance opinion — valuable for borderline names

Handelsregister Search — Free Public Database

The Handelsregister (commercial register) is publicly searchable for free at handelsregister.de. The search covers all registered companies across all German Bundesländer. You can search by company name (exact or approximate), registered location, Amtsgericht, and registration number. The register shows current registrations, historical entries, and publicly filed documents including articles of association. Phonetic similarity — not just exact match — is the relevant standard under §30 HGB.

HGB Name Requirements — §§17–37

The Firma (company name) of a GmbH is governed by §§17–37 HGB (Handelsgesetzbuch). The three core requirements are: (1) Distinctiveness — the name must be capable of distinguishing the company from others (Unterscheidungskraft); (2) Non-deceptiveness — the name must not mislead the public about the nature, scope, or location of the business (§18(2) HGB); (3) Public interest — §18(2) HGB prohibits names contrary to public interest. The GmbH suffix is mandatory under §4 GmbHG.

• §17 HGB: Firma is the name under which a company operates and signs documents — legal obligations attach to the Firma
• §18(1) HGB: Firma must have Unterscheidungskraft (sufficient distinctiveness) — purely generic descriptors alone are insufficient
• §18(2) HGB: Firma must not be misleading (Irreführungsverbot) — name suggesting bank, insurance, or public institution without licence is prohibited
• §30 HGB: Firma must be clearly distinguishable from existing firms in the same Amtsgericht district
• §4 GmbHG: GmbH name must contain "GmbH" or "Gesellschaft mit beschränkter Haftung" — abbreviation sufficient

Prohibited Terms and Restricted Words

Certain words in a German company name trigger automatic rejection by the Amtsgericht or require prior regulatory approval. Using a protected term without the underlying licence is grounds for rejection of the Handelsregister application and, if somehow registered, subsequent Löschungsklage (deletion proceedings). The Notar will typically flag these issues during the deed preparation phase — but the pre-clearance responsibility lies with the founders and their advisers, not the notary.

DPMA Trademark Search

The Deutsches Patent- und Markenamt (DPMA) maintains the German trademark register at dpma.de. A name search should check both registered trademarks (eingetragene Marken) and pending applications. Even a name approved by the Handelsregister can be challenged by a trademark owner under §15 MarkenG if it creates a likelihood of confusion (Verwechslungsgefahr). The DPMA Markenfinder tool allows phonetic, word, and figurative mark searches at no cost.

IHK Firmenname Advisory Service

Every German IHK (Industrie- und Handelskammer) offers a free Firmenname consultation for companies in its region. The IHK examines whether a proposed name complies with §§18, 30 HGB and provides a written Stellungnahme (opinion). While not legally binding on the Amtsgericht, IHK approval is treated as a strong positive indicator and significantly reduces the risk of rejection. Most IHKs process name queries within 3–5 business days at no charge.

• Free service — available via written application or online portal to your regional IHK
• IHK Stellungnahme is persuasive but not binding — Amtsgericht clerk makes the final decision
• IHK checks: distinctiveness, deception risk, prohibited terms, similarity to existing firms in the region
• Particularly valuable for: non-German language names, geographic names, descriptive names close to generic
• Some IHKs provide a letter of no-objection (Unbedenklichkeitsbescheinigung) which the Notar includes in the formation file

Name Reservation — What Is Actually Possible

Germany does not have a formal name reservation system in the Handelsregister — unlike some other jurisdictions. A name cannot be "reserved" before the formal Handelsregister application is filed. In practice, an IHK letter of no-objection combined with a quickly scheduled notary appointment provides the closest equivalent. Some practitioners use a Vorrats-GmbH (shelf company) strategy — purchasing a pre-registered GmbH and renaming it — as a way to secure Handelsregister entry quickly.

• No formal name reservation exists at the Handelsregister — §30 HGB priority is determined by date of registration
• IHK Unbedenklichkeitsbescheinigung is the practical substitute — issued before notary appointment
• Vorrats-GmbH strategy: acquire a shelf GmbH, rename via shareholder resolution + notary + Handelsregister — achieves entry in 5–7 days
• Once filed with the Notar (notarielle Beurkundung), the application is typically processed within 1–5 days by electronic filing
• Domain name should be registered immediately after notary appointment — domain law (§12 BGB, MarkenG) is separate from Handelsregister

Phonetic Similarity Test and Non-German Names

The similarity standard under §30 HGB looks at Verwechslungsgefahr (likelihood of confusion) — not just identical names. The Amtsgericht compares names phonetically (how they sound when spoken), visually, and conceptually. Non-German names are increasingly common in the Handelsregister and are generally accepted if they meet distinctiveness requirements. However, phonetic similarity to an existing German firm — even with different spelling — can still trigger rejection.

• §30 HGB test: "clearly distinguishable" (deutlich unterscheidbar) — applied to the overall impression of the name
• Phonetic similarity: "Müller Consulting GmbH" and "Muller Consulting GmbH" in the same district would conflict
• English names: fully accepted (e.g. "Digital Bridge GmbH") — no German language requirement under current HGB
• Geographic names as sole identifier: generally insufficient distinctiveness ("Berlin Services GmbH" alone rejected)
• Addition of distinctive element: "Berlin Digital Services GmbH" or "Berliner Innovationslabor GmbH" typically sufficient

Domain Name and International Trademark Clearing

Domain name availability should be checked in parallel with the Handelsregister and DPMA searches. German domain disputes fall under the DENIC dispute resolution policy for .de domains, and under the UDRP for .com/.eu domains. A company with Handelsregister entry and prior use of its name has strong standing in domain disputes, but early registration avoids costly proceedings. For internationally operating companies, an EUIPO EU trademark application provides Germany-wide and EU-wide protection for 10 years.

• Check .de domains at denic.de and .com/.eu at any registrar — .de is Germany's dominant ccTLD
• EUIPO EU trademark: single application covers all 27 EU member states — costs €850 for one class (10-year protection)
• WIPO TMview: free search covering 67 trademark offices including DPMA, EUIPO, USPTO — use for international clearing
• Priority rule: earliest trademark filing date wins (§6 MarkenG) — file EUIPO trademark as soon as name is confirmed
• DENIC Dispute: .de domain owner with a registered German company name has strong standing under DENIC dispute policy §3

Step-by-Step Name Clearance Checklist

A structured name clearance process minimises the risk of Handelsregister rejection and prevents costly post-registration disputes with trademark holders. The seven-step sequence below should be completed before the notary appointment is booked — not after. The entire process, including IHK consultation response time, typically takes 5–7 business days if run efficiently with all searches conducted in parallel.

• 1. Handelsregister search at handelsregister.de — check exact name and phonetic variants in target Amtsgericht district
• 2. DPMA Markenfinder search — check word marks, recent applications, and similar marks in relevant Nice classes
• 3. EUIPO TMview search — check EU trademark registrations that would apply Germany-wide
• 4. Domain availability — register .de, .com, and .eu simultaneously to prevent cybersquatting
• 5. IHK Firmenname enquiry — send proposed name + business description for written opinion
• 6. Notar review — Notar will check §§18, 30 HGB compliance before preparing the formation deed
• 7. Handelsregister filing — Notar submits electronically; Amtsgericht clerk reviews and registers within 1–5 days
