_The writing need not be very formal._ It need not specify the amount
that is to be paid; in other words, it need not specify the
consideration. Some courts say, however, that it must contain this
fact or statement. It may be in pencil. I presume it would be
sufficient if written on a blackboard with chalk. But it must be a
writing of some kind signed by the party to be charged; that is the
essential thing. The courts have also said that this writing need not
be on a single piece of paper. If the two parties have made an
agreement by a series of letters, an offer on the one side and an
acceptance on the other, and the agreement can be fully shown from the
series of letters, this is sufficient writing.
