This is probably the single question that is most often asked in Ireland online in forums, Reddit, Facebook groups, and these days by people to AI chatbots, and can you understand it why? Everyone has an opinion, but the legal answer to whether tree law can apply to you to take action about a neighbors tree is more precise than most would think. Read on for the true story.

The Short Answer: Yes, But Only Up to the Boundary

As per the Irish common law, you are allowed to trim any of your neighbour's tree's branches or roots that lean or grow into your property. You may do so without a licence from them, provided that you do not step onto their property. However, all trimming should be conducted to the property line boundary only.

The Rules You Actually Need to Follow

That right comes with real limits:

  • You can't trespass. All cutting has to be done from your own side of the boundary, unless your neighbour agrees to let you access their land.
  • You can only cut back to the boundary. Not beyond it, and not in advance of a branch actually growing over.
  • The cuttings still belong to your neighbour. Branches, leaves, and fruit you remove are technically still their property. You should offer them back, and if they don't want them, disposing of them properly becomes your responsibility.
  • The work has to be done carefully. If careless cutting damages the tree or leaves it unstable, you could end up liable for that.

What About Roots?

As for the roots, although you have the same right for them, they pose a bit more of a problem. When you sever parts of a neighbor's roots, you might disturb a tree enough that it will fall over from shaking. If it does fall on something and someone, you might be responsible.

Or, of course, if these roots are causing actual damage such as cracked paving or the driveway is breaking apart or your drains are not working properly, then you might want to consider pursuing a nuisance claim against the tree's owner. That's assuming, though, you can prove they are the ones responsible.A proper tree survey or risk assessment gives you documented, professional evidence rather than just your word against theirs.

When You Might Need to Go Further

How to sort out tree boundaries Tree boundaries are normally sorted by a simple conversation If you've got a boundary tree problem, simply going and talking to your neighbor can often sort things out. Explain nicely what's going on and suggest that you come and look at the tree with him can work more than people realize. If that in practice is just impossible and you have to access the neighbour’s boundary to complete a pruning job on the tree, you can in theory actually take out court proceedings for an order under section 45 of the land and conveyancing law Reform Act 2009. Before going down that route of the court orders get legal advice however as all cases are slightly different.

One Thing Worth Checking First

Be warned: before you lay a chainsaw to any branches at all, double-check the tree isn't "preserved." This means the tree isn't already the subject of a Tree Preservation Order, or positioned within a protected conservation zone. In either case, you might have to get consent from the local council to carry out the work, even if it's only some normal overhanging branches on your neighbour's side.

Why It's Worth Calling a Professional Rather Than DIY-ing It

Getting boundary tree work wrong can go two ways: doing too little and leaving a genuine nuisance unresolved, or doing too much and damaging a tree you don't actually own, which can create liability of its own. A qualified tree surgeon knows how to prune back to the boundary correctly, without weakening the tree or overstepping what the law allows.

Frequently Asked Questions

Can I cut branches that overhang from my neighbour's tree in Ireland? 

Yes, you can cut back overhanging branches to the boundary line without needing permission, as long as you don't enter your neighbour's property to do it.

Do I need my neighbour's permission to prune overhanging branches? 

No, not for branches overhanging your own side, provided you stay off their land and only cut back to the boundary.

What do I do with the branches I cut off? 

They technically still belong to your neighbour. Offer them back first; if they don't want them, you're responsible for disposing of them properly.

Can I cut roots that are damaging my property? 

Generally yes, but carefully. Cutting roots can destabilise the tree, so it's worth getting professional advice, especially for a mature or large tree.

What if my neighbour refuses to let me deal with the problem? 

Start with a calm conversation. If that fails and access is genuinely needed, there's a legal route through the courts, though it's worth getting legal advice before pursuing that.
