Sheriff officers may only enter your home if they have the correct authority from the courts to do so. You can ask the sheriff officers to provide evidence of this by showing you the document stating they can enter your home.
If you refuse entry to a sheriff officer (who has the necessary authority) they may use ‘necessary reasonable force’ to enter. This means that, provided they have the correct authority, they can force open a door or break a locked window to gain access to your property.
Where you refuse entry to a sheriff officer you may also be charged with breach of the peace.
Sheriff officers can only force entry where they are enforcing an eviction.
