How do I know who owns the boundary between my property and next door?

A: Once again you should first check the legal documents. However, the boundaries between properties can differ from those described in the title documents or lease in certain circumstances. The most common are where they have been changed by agreement or by encroachment (occupation without permission). If you think that the boundaries are not defined in the title document or lease, or that the boundaries have been changed by agreement or encroachment, you will probably need to get legal advice.
