Accession

15 January, 2016 - 09:41

An accession is something that is added to what one already possesses. In general, the rule is that the owner of the thing owns the additional thing that comes to be attached to it. For example, the owner of a cow owns her calves when she gives birth. But when one person adds value to another person’s property, either through labor alone or by adding new materials, the rule must be stated somewhat differently. The general rule is this: when goods are added to goods, the owner of the principal goods becomes the owner of the enhanced product. For example, a garage uses its paint to repaint its customer’s automobile. The car owner, not the painter, is the owner of the finished product.

When someone has wrongfully converted—that is, taken as her own—the property of another, the owner may sue for damages, either to recover his property or its value. But a problem arises when the converter has added to the value of that property. In general, the courts hold that when the conversion is willful, the owner is entitled to the full value of the goods as enhanced by the converter. Suppose that a carpenter enters a ten-acre forest that he knows belongs to his neighbor, cuts down one hundred trees, transports them to his shop, and cuts them up into standard lumber, thus increasing their market value. The owner is entitled to this full value, and the carpenter will get nothing for his trouble. Thus the willful converter loses the value of his labor or materials. If, on the other hand, the conversion was innocent, or at most negligent, the rule is somewhat more uncertain. Generally the courts will award the forest owner the value of the standing timber, giving the carpenter the excess attributable to his labor and transportation. A more favorable treatment of the owner is to give her the full value of the lumber as cut, remitting to the carpenter the value of his expenses.
