If you've ever looked at your garden fence and thought, "Which side of the fence is mine?" you're not alone. Confusion around property boundaries has been the cause of countless disputes between neighbours for many years. In the UK, understanding which side of the fence is your responsibility is of immense importance, especially when it comes to maintaining or replacing it. In this comprehensive guide, we explore this complex topic in detail while providing expert advice for UK homeowners.

The Importance of Property Boundaries:

Knowing your property boundaries is crucial for various reasons. Besides avoiding neighbourly disputes, an accurate understanding of your boundaries can also help prevent legal issues or unexpected financial costs. Additionally, understanding your responsibilities is essential when seeking any local council approvals for home improvements or extensions.

Identifying Your Side of the Fence:

It's not always obvious which side of the fence belongs to you, and there is no one-size-fits-all rule. However, the UK has some general guidelines, and here are a few pointers to make things clearer for you:

1. Check your property deeds: The title plan attached to your property deeds should provide ownership details, including fence responsibility. Consulting this document should be your first step to identifying your boundaries.  

2. The 'T' mark: If your property deeds do not clarify the situation, look for a 'T' mark on the title plan. The 'T' is usually placed against the boundary line, and its base indicates which side of the fence is your responsibility.

3. The property age: Generally, if your property is on the left side of a straight road, you're responsible for the fence on the left. Conversely, if your house is on the right side, you are accountable for the right fence. However, this rule mainly applies to properties built between 1930 and 1960.

4. Adverse possession: Suppose you've been maintaining a particular side of the fence for an extended period of time without objection from your neighbour. In that case, you might gain legal rights over this land, even if it wasn't designated as your property initially. This concept is known as adverse possession and can help settle fence disputes.

Resolving Disputes:

Despite your best efforts, property boundary disputes can occur. Polite and open communication is the first step to resolving any disagreements. If that fails, professional mediation or even legal action could be necessary.


The question, "Which side of the fence is mine?" might seem simple, but it involves careful consideration and investigation. As a UK homeowner, understanding your property boundaries is crucial to maintaining healthy relationships with your neighbours and avoiding possible legal issues. When in doubt, consult your property deeds, or don't hesitate to seek professional advice.
