Plain English: it's possible

[Lawyers] are perfectly capable of verbally communicating the essence of a document to the client sitting across the desk but feel that they are undertaking a formalistic task requiring different skills when they attempt to put the same thing in writing.

—Sidney F. Parham, Jr., The Fundamentals of Legal Writing 73 (Michie Co. 1967).

[I]t is possible to write any legal document in the sort of language we use every day.

—Michele M. Asprey, Plain Language for Lawyers 2 (2d ed., Federation Press 1996).
