Where the parties, without any fraud or mistake, have deliberately put their engagements in writing, the law declares the writing to be not only the best, but the only, evidence of their agreement. All preliminary negotiations, conversation and verbal agreements are merged in and superseded by the subsequent written contract . . . and unless fraud, accident or mistake be averred, the writing constitutes the agreements between the parties, and its terms and agreements cannot be added to nor subtracted from by parol evidence.
Morrison v. AccuWeather, Inc., Civil Action No. 4:14-cv-0209, 17 (M.D. Pa. Jul. 14, 2015)
As with any contract, it is essential to the enforceability of a settlement agreement that
“the minds of the parties should meet upon all the terms,
as well as the subject-matter, of the [agreement].”
Onyx Oils & Resins, Inc. v. Moss, 367 Pa. 416, 420, 80 A.2d 815, 817 (1951).)
