My sister's getting married and I've made the check out to her and her soon to be husband. (2 different names) Will they have a problem cashing this if they don't have a joint account. Can one of them just sign the back and the other cash it? Also I didn't cross the check (&Co) as I understand that nowadays a check can only be cashed by the person who is written on the check. Is this correct? Finally can checks still be made out to cash.
