Common questions

Why does the letter need to name the client explicitly, not just the retaining party?+

In litigation and fraud engagements the party paying the fee, for example an attorney or insurer, is not always the party the accountant's duty of care and privilege run to, so naming the client clearly avoids later disputes over who owns the work product and who it can be disclosed to.

What happens if the scope of work changes after the engagement letter is signed?+

A material change in scope, such as extending the analysis to a new time period or additional entities, normally requires a written amendment or supplemental letter, since undocumented scope creep can undermine the engagement's defensibility if the work product is later challenged.
