If you are a seller, the standard real estate contract states that these are documents that you must provide to the buyer, unless set out otherwise in the standard real estate contract. These confirm that the building location warranties given by the seller in the contract are true. If you are a buyer, you will have comfort that all is well and there is no risk that, for example, a building or improvement encroaching on a neighbouring lot or utility right-of-way might have to be moved or removed entirely.
