> I think the reason contracts aren't readable to laypeople is because laypeople aren't the intended audience. This doesn't make sense. The parties to the contract are presumably laypeople, and they have to understand it before they agree to it and sign it since one of the legal requirements for a valid contract is a meeting of the minds, meaning a common understanding between the parties of what each of them is agre…
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.
You don't. Once you sign a written contract, the presumption is that there was a successful meeting of the minds between the parties. If you later want to claim that you didn't have a meeting of the minds with the other party, the burden of proof is on you to show that. The other party does not have to prove that you did understand the contract.
