Does a lease contract become void if it was signed, but with completely wrong names typed in?

The word "void" is so harsh and absolute, while the law is usually much more nuanced.  Because the contract was signed, it has the right names of the people on it; just in cursive writing rather than typed.  The typed names being wrong could be something to argue about, as it raises a degree of ambiguity, but the intent is pretty clear. Plus, the hand written part is more persuasive of the intent than the typed names. The law generally tries to carry out the intent of the parties, even if there is a mistake in the expression.
