IANAL, How would you prove that? I think there are protected classes for that reason, but if some adult outside of such classifications signs they could ostensibly renege at any point under the pretense that they didn't understand, conversely I presume it would necessitate attorneys (or similar) at every contract signing to ensure it would be binding.
Fyi in practice, signing the document means that you understand it, as far as a court is concerned. Contracts will often throw in boiler plate like "I am authorized to sign this, I've read it, and I understand and agree to it."
The most common way it's successfully challenged is "incompetence" - by showing the person who signed it in no way could have possibly understood it (e.g. developmentally disabled, someone held a gun to their head, don't speak the language and the translation was fraudulent, etc).
