The instrument which conveys the property is also called a conveyance. The whole of a conveyance, when it consists of different parts or instruments, must be taken together and the several parts of it relate back to the principal part; as a fine or a recovery. When there is no express agreement to the contrary, the expense of the conveyance falls upon the purchaser who must prepare and tender the conveyance.
