All encumbrances shown upon the report of title, other than those waived by the purchaser or which the contract provides are to remain, must be removed. This it is the seller's duty to do. He must deliver a title free and clear of all encumbrances except such as are, by the contract, specifically excepted. Customarily the purchaser, as soon as he receives his report of title, notifies the seller of all encumbrances which must be removed. The seller should come to the closing prepared to remove all such encumbrances. If it is a mortgage which is to be satisfied, he should have the holder present with a satisfaction piece ready for delivery. The same arrangement may be made with reference to a judgment which is a lien. Often for convenience the mortgagee or holder of the judgment gives a statement of the amount due him, and the purchaser or his attorney holds out that amount from the price, going to him after the closing, paying the amount stated and receiving the satisfaction piece. If a title company closer is closing the title, it is customary for him to hold the money for this purpose and secure the satisfaction piece. Very often the property is subject to the lien of unpaid taxes. It is usual then for the purchaser or his representative to hold out an amount sufficient to pay them. They are later paid by him and any surplus returned to the seller.
