Section 13. Implied Warranties of Title.—

In a contract to sell or a sale, unless a contrary intention appears, there is—

1. An implied warranty on the part of the seller that in case of a sale he has a right to sell the goods, and that in case of a contract to sell he will have a right to sell the goods at the time when the property is to pass;

2. An implied warranty that the buyer shall have and enjoy quiet possession of the goods as against any lawful claims existing at the time of the sale;

3. An implied warranty that the goods shall be free at the time of the sale from any charge or encumbrance in favor of any third person, not declared or known to the buyer before or at the time when the contract or sale is made.

4. This section shall not, however, be held to render liable a sheriff, auctioneer, mortgagee, or other person professing to sell by virtue of authority in fact or law goods in which a third person has a legal or equitable interest.
