The seller promises that there are no encroachments on or by the subject property being transacted. However, it is up to the buyer to ‘test’ this promise. Obtaining a survey can be beneficial, particularly for large or unusual blocks that may have easements or right of ways involved, especially if you are intending on carrying out future works to the property.
An alternative is title insurance; this is a type of insurance that assists with a wide range of risks that may arise with property ownership, including dealing with encroachments.
