The English conditions are known as the A.B. Stewart conditions or, in the latest version, only "ABS conditions". The full name of the latest version of the English conditions is Loss of Charter Hire Insurance - Including War (ABS 1/10/83 Wording). These conditions are subject to English law and practice. They contain no jurisdiction or arbitration clause.
The U.S. conditions are known as the Lazard form, or in its full name, Loss of Charter Hire Form (August 1961). There is no choice of law clause in the Lazard form, but Clause J provides for New York arbitration.
