We’ve handled a lot of cases where, say, a Spanish-speaking consumer negotiates a deal in Spanish, and cannot read English, but is presented a contract in English at the end of the negotiations. The Spanish-speaking salesperson inevitably says, “Don’t worry, just sign it. It’s the same as we just discussed.” It never is.
California Civil Code Section 1632 requires that, if a dealer negotiates a deal in certain languages (Spanish, Korean, Chinese, Tagalog or Vietnamese), then the dealership must present the consumer with a contract in that language. If the dealership fails to do this, the consumer can rescind the deal, i.e. have it unwound.
I know you’re probably reading this in English, but you should let your friends who speak other languages that, if the deal is negotiated in a different language, the consumer is entitled to a contract in that language.
Hope this helps.
