This article is for Irish company directors and business owners who need to choose or change their company name without running into legal problems.
If you're wondering whether the CRO can force you to change your name, how trademark issues might affect you, or what happens if your chosen name conflicts with existing companies, this guide covers CRO name rules, trademark infringement risks, and the complete name change process.
Key Takeaways
• The CRO can force a name change within 6 months of incorporation if your name is too similar to existing companies.
• Always search the Irish Patents Office trademark register before incorporating to avoid costly infringement claims later.
• You must file Form G1 within 15 days of passing a special resolution to change your company name.
• Ignoring CRO name change directions can result in strike-off, and trademark injunctions often exceed €20,000 in legal costs.
• Check name availability immediately before your shareholder meeting since you cannot reserve names for existing companies changing names.

When Can the CRO Force You to Change Your Name?
The Companies Registration Office monitors company names to prevent confusion and protect the public. The Companies Act 2014 gives the Registrar power to direct name changes within 6 months of incorporation if your name is "the same as or too like" an existing company name.
"Too like" means more than superficial similarity. The CRO considers whether the names would confuse members of the public dealing with either company.
The 6-month window is strict. After incorporation, you have 6 months of uncertainty. The CRO might direct a name change at any point during this period.
After 6 months expire, the CRO loses this power and you gain certainty that similarity objections won't force changes.
Business sectors influence similarity assessments. Two companies with similar names operating in completely different industries might both be permitted. A technology company and a bakery can share similar names because confusion is unlikely. However, two accounting firms with similar names face objection regardless of geographic separation.
Prior companies take priority. First registration wins. If Company ABC Limited exists and you incorporate ABC Ireland Limited, the CRO will likely object. The established company's name takes precedence over new registrations.
What Trademark Issues Force Name Changes?
Trademark law operates independently from company registration. You can successfully incorporate a company name through the CRO but still face trademark infringement claims forcing changes later.
Registered Trademarks Provide Strong Protection
Trademark owners can seek High Court injunctions preventing you from using names that infringe their marks. This applies even if the CRO approved your name. The CRO doesn't check trademark registers before approving company names.
The "Likelihood of Confusion" Test Determines Infringement
Courts examine whether consumers might confuse your company with the trademark owner's business. Consider these scenarios:
- Identical names in identical sectors: Almost certainly infringe
- Similar names in related sectors: Might infringe depending on specific circumstances
- Different names in unrelated sectors: Generally safe unless dealing with well-known marks
Well-Known Marks Receive Broader Protection
Famous brands like Coca-Cola or Apple receive protection even against use in unrelated sectors. Using these names for any company type invites immediate legal action regardless of your business activities.
Trademark Searches Before Incorporation Prevent Problems
The Irish Patents Office maintains a searchable trademark register. Checking this register costs nothing and reveals registered marks that might conflict with your proposed name. Professional trademark searches provide more comprehensive results.
Which Name Elements Are Prohibited?
The Companies Act 2014 and CRO policies prohibit certain words and elements in company names. Using prohibited elements results in registration rejection or forced changes after incorporation.
- Government-related terms require permission. Words like "Government," "Authority," "Commission," or "National" suggest official status. The CRO requires written approval from relevant government departments before allowing these terms.
- Professional regulation terms need authorization. "Bank," "Insurance," "University," and similar terms implying regulatory oversight require proof of proper licensing.
- Offensive or misleading terms face rejection. The CRO refuses names containing obscenities, discriminatory language, or terms likely to mislead the public.
What's the Procedure for Changing Your Company Name?
Name changes follow a straightforward process whether voluntary or forced.
The Five-Step Name Change Process
Step 1: Pass a Special Resolution
Pass a special resolution (75% majority of votes cast). Single-member companies simply record the decision. The resolution must specify both old and new names.
Step 2: Check Name Availability
Search the CRO website before passing your resolution.
This prevents wasting time on unavailable names.
Remember: informal checks don't guarantee approval.
Step 3: File Form G1 Within 15 days
Comply with the applicable filing costs.
Late filing attracts penalties.
Step 4: Receive Your New Certificate
The CRO issues a new Certificate of Incorporation.
It shows your original incorporation date plus the name change endorsement.
Step 5: Update All Business Materials
You must update your company name on all business letters.
Update immediately:
- Letterhead and business cards
- Website and email signatures
- Physical signage
- Bank accounts and contracts
The name change takes effect only when the Registrar issues the new Certificate of Incorporation.
What Happens If You Ignore a Name Change Direction?
Ignoring CRO directions to change your name creates escalating problems. The Registrar has enforcement powers ensuring compliance.
Strike-off becomes possible under the Companies Act 2014. Failure to comply with lawful CRO directions constitutes grounds for involuntary strike-off. The CRO issues warning notices before actually striking off the company, but continued non-compliance results in dissolution.
You can't file other documents while non-compliant with name change directions. Non-compliance may trigger further enforcement steps, potentially affecting annual return filings.
Trademark injunctions include costs orders. Courts typically award legal costs against defendants in successful trademark infringement cases. These costs often exceed €20,000 in High Court proceedings. The longer you delay changing the name, the higher the legal costs when injunctions finally force compliance.
Personal director liability can arise in extreme cases. Trading under a name you know infringes another's rights potentially creates personal liability for directors who authorised continued use despite warnings.
Can You Reserve a Name Before Changing?
The Companies Act 2014 allows name reservation for proposed companies. This prevents others taking a name while you prepare incorporation documents.
You cannot reserve names for existing companies considering changes. The CRO reservation system only works for new incorporations. When changing names, you risk someone else registering your desired name between checking availability and filing your change.
Speed minimises this risk. Pass the special resolution and file required form on the same day. Check name availability immediately before the shareholder meeting. This compressed timeline reduces the window where someone else might register your chosen name.
