Is a contract legal if a person who does not speak understand or write English signs a contract buying a car with a minor doing the translation?

Answer 1

The fact that the translator was a minor does not make the contract unenforceable. The key issue is whether the parties understood the nature and terms of the agreement. That is a question of fact, not law, a court could decide in one case that the minor acted as a competent translator and the party fully understood the contract; and at the same time another court could rule that the minor did not understand the full nature of the language and did not translate effectively precluding in the law what is called the 'meeting of the minds'
