Mixed Ambiguity Law and Legal Definition

Mixed ambiguity is an uncertainty that is partly latent and partly patent. It combines some elements of latent and patent ambiguity.

When the words of a document are susceptible to opposing interpretations, a form of latent or mixed ambiguity is said to arise. Parol evidence may be received not to vary or modify the terms of the agreement but to aid the court in ascertaining the true intent of the parties, not to show that the parties mean something other than what they say, but to show what they mean by what they say.
