Thanks for your message. No hurry re my question. It has become a minor question between me and a friend. I've always thought, perhaps incorrectly that a contract relating to real estate must be in writing, and involve an exchange of something of value, such as money. Admittedly I'm an American, and State law prevails, (large drawn from "common law". Anyway, when and if convenience I would find it interesting to know if I'm correct, or off base.
Thank's for your response. It's been sixty-five years since I read "contract law", and it's a relief to know I've not forgotten the necessity for "consideration". Separately, I attempted to deposit a small check today, and was chagrined to find I had not noticed before doing so that the check writer had not dated the check. Bah hum!
