ABSTRACT
Over the past 20 years, a great deal of progress has been made in what we now call the law of obligations. This includes contract, tort, unjust enrichment, and a variety of equitable obligations, such as fiduciary duties, duties of confidence, and duties created by estoppel. However, by definition, the law of obligations excludes the law of property. By obligations, we mean the obligations that correspond to personal rights. An obligation exists only because a particular person has a legal right to enforce it. The obligation and the personal right are two sides of a coin.
