Startup founders, CEOs, HR professionals, and legal teams in Ireland hiring senior employees or drafting contracts.
Readers will gain practical insights on creating enforceable restrictions, avoiding common pitfalls with templates, and using alternatives like garden leave to safeguard business interests effectively.
Key Takeaways
- Non-compete clauses are void unless protecting legitimate interests like confidential info or client relationships, and reasonable in duration, geography, and scope.
- Durations of 6-12 months, local geography, and role-specific scopes increase enforceability chances.
- Non-solicitation clauses for specific staff or clients are generally easier to enforce if limited and targeted.
- Garden leave provides reliable protection during notice periods as employees remain paid and bound by duties.
- Courts strike down overly broad clauses entirely without rewriting; tailor contracts specifically to roles.

What's the Difference Between Non-Compete, Non-Solicit, and Non-Dealing Clauses?
These three terms are often lumped together, but they restrict very different things.
Non-compete clauses stop a former employee from working for a competitor or starting a competing business.
Non-solicitation clauses stop them from actively approaching your clients or staff after they leave.
Non-dealing clauses go further, they stop any contact with specific clients, even if the client initiates it.
Why Do Irish Courts Strike Down Non-Compete Clauses?
The starting point in Irish law is that restraint of trade clauses are void unless justified.
Courts apply a two-part test: a restriction must protect a legitimate proprietary interest, and it must go no further than reasonably necessary to do so.
That second test is where most non-competes fail.
A restriction that prevents a sales rep from working anywhere in Europe for two years is likely unenforceable, even if both parties signed it willingly.
Courts won't enforce what they consider an unreasonable attempt to restrain competition, regardless of what the contract says.
What Makes a Non-Compete Clause Enforceable?
There are three things courts look at.
Duration: How Long Does the Restriction Last?
Shorter is better, and there is no magic number. Six to twelve months is generally accepted for senior employees with access to confidential information.
Anything beyond 12 months faces serious scrutiny, and two-year restrictions are regularly struck down.
The test is whether the duration gives the business enough time to protect the interest at stake, not how long it would take a competitor to benefit.
Geography: Where Does the Restriction Apply?
The geographic scope must reflect where the employee actually operated.
A restriction covering worldwide activity is almost always too broad unless the employee genuinely had a global remit.
For most roles, limiting the restriction to the country or specific regions where the employee had client relationships is more likely to hold.
Scope: What Exactly Is Restricted?
A restriction that bans an employee from working in an entire industry will usually fail.
Courts ask: what was the employee actually doing, and what legitimate interest does the business have to protect?
A software developer who had no client relationships and didn't work with confidential pricing data is harder to restrict than a senior account manager who held key client relationships for years. The narrower the scope, the more likely it survives.
What Counts as a Legitimate Business Interest?
Irish courts recognise two main interests that can justify restrictions.
Confidential information -trade secrets, pricing strategies, product roadmaps, proprietary processes.
Customer and supplier relationships - particularly where the employee was the primary contact and could take those relationships with them.
General skill, knowledge, or experience that an employee builds up over time is not a protectable interest.
You cannot restrict someone from using their general expertise in a new job, even if you trained them.
What About Non-Solicitation Clauses for Staff?
Non-solicitation of employees clauses, stopping a former employee from poaching your team, are generally enforceable if drafted properly.
They need to:
- Be limited in time (typically 6 to 12 months)
- Cover specific employees, not all staff
- Target active solicitation, not passive job applications
A blanket ban on a former employee ever working with anyone from your company is too wide.
The clause needs to name or clearly identify the individuals it covers, not sweep up the entire organisation. Courts have struck down restrictions worded as "any employee" or "all staff" because they effectively prevent someone from working in their industry at all. Target the people the departing employee actually managed, mentored, or recruited.
Garden Leave: Often More Reliable Than a Non-Compete
Garden leave means keeping an employee on the payroll during their notice period while they stay home.
During that time, they remain employed, owe duties of confidentiality and good faith, and cannot work for a competitor.
For senior hires, a well-drafted garden leave clause combined with a shorter non-compete is often more defensible than a long non-compete alone.
Courts view garden leave more favourably because the employee is still being paid.
Practical Drafting Principles for Startups
Most startup contracts include non-competes copied from templates without tailoring them to the role. That's how you end up with a clause that looks protective but wouldn't survive a challenge.
Here's what to focus on when drafting:
- Match the restriction to the role - a junior developer needs a different clause than a head of sales
- Be specific about the restricted activities - "working for a competitor" is vague; narrowing it to specific services in a specific market is more defensible
- Keep duration short and defensible - 6 months is more likely to be enforced than 18
- Limit geography to where the employee actually operated
- Include a non-solicitation clause as a fallback - if the non-compete fails, you still have protection for client and staff relationships
- Consider garden leave for senior hires - it's stronger in practice and easier to enforce
What Happens If a Clause Is Unenforceable?
Courts in Ireland do not rewrite contracts, if a non-compete clause is too wide, the court will strike it down entirely - they will not reduce it to a reasonable scope for you.
This is called the blue pencil test: courts can remove an unenforceable clause, but they won't redraft it.
Some contracts include a severance provision allowing courts to modify the clause, but Irish courts have been cautious about using this to rescue poorly drafted restrictions.
The result is that a founder who spent money having contracts drafted can end up with no protection at all - simply because the clause was too broad. We see this regularly with template contracts pulled from the internet that haven't been tailored to the specific role or business.
The practical lesson: draft it right the first time. A tighter, more specific clause that actually holds up is worth far more than a sweeping restriction that gets thrown out the moment it's challenged.
