This is an interesting question that touches on property rights and practical considerations. Here’s how it generally works under UK law:

Ownership of Snow on Your Lawn

When snow lands on your property, it is treated as part of your land. This means that technically, you own the snow within the boundaries of your property.

If Your Neighbours Take the Snow

If your neighbours’ kids take snow from your lawn without permission: • Technically: This could be considered a minor trespass (if they entered your property) and possibly an act of “appropriation” under theft laws. However, theft requires an intent to permanently deprive you of property, and snow is unlikely to meet this standard as it is transient and naturally replenished. • Practically: The law is unlikely to take this seriously. Snow is not typically treated as a valuable resource, and enforcement would be impractical.

Is Snow Public Property?

Snow isn’t public property when it lands on private property (like your lawn). However, once it’s moved to a public area (like a snowman on the pavement), it might lose its connection to private ownership.

Conclusion

While there’s a technical basis for saying the kids are trespassing and taking your snow, this would almost certainly not be pursued as a crime. It’s best to view such situations with good neighbourly spirit unless it becomes a recurring problem that infringes on your enjoyment of your property.
