In order to pass the property by a sale, there must be an express or implied agreement that the title shall pass. But, on the contrary, when the making of part payment, or naming a day for payment, clearly shows an intention in the parties that they should have some time to complete the sale by payment and delivery, and that they should in the meantime be trustees for each other, the one of the property in the chattel, and the other in the price. As a general rule, when a bargain is made for the purchase of goods, and nothing is said about payment and. Sales are absolute or conditional. A conditional sale is one which depends for its validity upon the fulfilment of some condition.
Sales are also voluntary or forced, public or private.
A forced sale is one made without the consent of the owner of the property by some officer appointed by law, as by a marshal or a sheriff in obedience to the mandate of a competent tribunal. This sale has the effect to transfer all the rights the owner had in the property, but it does not, like a voluntary sale of personal property, guaranty a title to the thing sold it merely transfers the rights of the person as whose property it has been seized. This kind of a sale is sometimes called a judicial sale. A public sale is one made at auction to the highest bidder. Private sales are those made voluntarily and not at auction.
