This is a myth. Most contracts are not even written down and are perfectly legal. For example if you're in a restaurant and order food you have accepted a contract to pay for that food once you finish. The contract does not include any legalese it isn't even written down, yet is just as valid if not more so as any 100 page document filled with legalese. If this is so you can also write it in plain English. Anything that can be written in legalese can almost always be rewritten in more concise plain readable English.
