Verba volant, scripta manent is a Latin proverb, which translates as "(spoken) words fly away, written ones remain". Other versions include verba volant, (sed) littera scripta manet, "(spoken) words fly away, but the written letter remains".[1] [2]
The authorship of this proverb is, as with many others, unknown, but it was well-known by the seventeenth century, when it was used in Francis Turretin's "De Libro Vitae".[3]
The general meaning is that spoken words are ephemeral, and easily forgotten or disputed, but writing can be relied on to prove what was said or agreed to. Applied in a legal context, it means that if people wish to establish a formal agreement, it is best to put it in writing, in order to avoid the disputes that may arise from an oral agreement.
