A Brief Introductory Guide to the
English Law of Guarantees
UK – 5 July 2023
This is an introductory guide to aspects of the English law of guarantees. It is useful to note at
the outset that the commercial usage of the term “guarantee” is not always aligned with the
technical legal meaning of that term.
There are many different types of documentary instruments Confusingly, both a true guarantee and an indemnity are
