HYPOTHECATION, civil law. This term is used principally in the civil law; it is defined to be a right which a creditor has over a thing belonging to another, and which consists in the power to cause it to be sold, in order to be paid his claim out of the proceeds.

2. There are two species of hypothecation, one called pledge, pignus, and, the other properly denominated hypothecation. Pledge is that species , of hypothecation which is contracted by the delivery of the debtor to the creditor, of the thing hypothecated. Hypothecation, properly so called, is that which is contracted without delivery of the thing hypothecated. 2 Bell's Com. 25, 5th ed.

3. Hypothecation is further divided into general and special when the debtor hypothecates to his creditor all his estate and property, which he has, or may have, the hypothecation is general; when the hypothecation is confined to a particular estate, it is special.

4. Hypothecations are also distinguished into conventional, legal, and tacit. 1. Conventional hypothecations are those which arise by the agreement of the parties. Dig. 20, 1, 5.

5. - 2. Legal hypothecation is that which has not been agreed upon by any contract, express or implied; such as arises from the effect of judgments and executions.

6. - 3. A tacit, which is also a legal hypothecation, is that which the law gives in certain cases, without the consent of the parties, to secure the creditor; such as, 1st. The lien which the public treasury has over the property of public debtors. Code, 8, 15, 1. 2d. The landlord has a lien on the goods in the house leased, for the payment of his rent. Dig. 20, 2, 2; Code, 8, 15, 7, 3d. The builder has a lien, for his bill, on the house he has built. Dig. 20, 1. 4th, The pupil has a lien on the property of the guardian for the balance of his account. Dig. 46, 6, 22; Code, 6, 37, 20. 5th. There is hypothecation of the goods of a testator for the security of a legacy he has given. Code, 6, 43, 1.

7. In the common law, cases of hypothecation, in the strict sense of the civil law, that is, of a pledge of a chattel, without possession by the pledgee, are scarcely to be found; cases of bottomry bonds and claims for seamen's wages, against ships are the nearest approach to it; but these are liens and privileges rather than hypothecations. Story, Bailm. §288. It seems that chattels not in existence, though they cannot be pledged, can be hypothecated, so that the lien will attach, as soon as the chattel has been prodced. 14 Pick.
