Restatement of Security & Suretyship and Guaranty

Security & Suretyship and Guaranty

"Security is an interest in chattels, in land, or in the obligation of a third party. . . . The purpose of security is generally to secure the repayment of money, but it may also secure the performance of any duty." Scope Note to Restatement of the Law of Security at 1 (Am. Law Inst. 1941).

Suretyship is "the legal relation that arises when one party assumes liability for a debt, default, or other failing of a second party." Suretyship, Black's Law Dictionary 1671 (10th ed. 2014).

Guaranty is "a promise to answer for the payment of some debt, or the performance of some duty, in case of the failure of another who is liable in the first instance." Guaranty, Black's Law Dictionary 821 (10th ed. 2014).

Superseded Status

The Restatement of the Law, Third: Suretyship and Guaranty "should be regarded as completely superseding Division II of the Restatement of Security. Division I of that Restatement has long been largely superseded by Article 9 of the Uniform Commercial Code." Forward to Restatement (Third) of Suretyship and Guaranty at IX (1996).

For more information on superseded status, see the publication page at or contact the American Law Institute.

Parallel Tables

To help researchers navigate between the different Restatement series, ALI includes "parallel tables", found before the index of most Restatement subjects. These tables show corresponding section numbers between two series of Restatements. Some parallel tables may connect section numbers of the final Restatement with one or more earlier drafts. When using these parallel tables to find where an older series (or draft) section is located in a newer series, be sure to check all volumes of the current series - the parallel tables only point to the sections found in that particular volume.

The Parallel Tables found in the back of Restatement (Third) Suretyship and Guaranty show corresponding Restatement (Third) Suretyship and Guaranty, Restatement (Second) Contracts, Restatement of Security (1941), and Restatement (Third) Suretyship and Guaranty Tentative Drafts 1-4 section numbers.

The Parallel Tables found in the back of Restatement of Security (1941) show corresponding Restatement of Security (1941), Tentative Drafts 1-4, and Proposed Final Draft section numbers.
