A conditional or qualified acceptance of an offer does not constitute an agreement unless the condition is complied with.1 Such an acceptance is a counter-offer, which, even if it purports to be an acceptance, is equivalent to a rejection. Among examples of conditional acceptance which do not create a contract are the following: an acceptance of an offer to obtain land at execution sale, conditioned on the offeror's giving an obligation that the land would not cost over a certain sum;2 an offer to give to a party who was trying to secure the title to certain realty for two owners thereof, by which the owners agreed to give him "your share as well as my sister and I," followed by a counter-proposition to secure the title for one-half of the realty;3 an acceptance of a request to borrow money on real estate security, which was never given;4 an acceptance conditioned on giving certain security, which was never given;5 or of transmitting certain information to the party accepting;6 or of furnishing the written legal opinion of the city attorney that the bonds offered for sale were legal;7 an acceptance conditioned on the assent of a third person, which is never given;8 a letter stating that the writer's acceptance when confirmed by a certificate of agency from the sendee is an agreement of agency, the letter not being assented to and the certificate not signed;9 an acceptance conditioned on payment to acceptor of insurance received by adversary party for loss of a building on the land contracted for, which was refused.10 A counter-proposition operates as a rejection of an offer even if the offeree performs some services referable to such offer.11

Since the acceptance with an attempted modification is at least a counter-offer, it may be accepted by the original offeror, and thus may constitute a contract.12

An acceptance which adds a condition not incorporated in the offer does not prevent the contract from existing if both parties treat it as in existence,13 or if the parties assume that such added term is a part of the contract.14 Thus a valid agreement is produced by A's offer to B's agent to sell subject to B's approval, B's approval subject to new conditions, and A's acceptance of such new conditions,15 and so where the offer was to take a thirty-day acceptance of a draft, and a note was offered and accepted.16 If the so-called acceptance provides for a delay in delivery, the delivery and acceptance of the goods is an acceptance of such counteroffer.17 An offer to sell railway ties, "to be delivered this year and next," is not accepted by a letter which offers to take all the ties "delivered within the next twelve months"; but shipping ties under such counter-offer is in effect an acceptance thereof.18 A telegram of acceptance by the party who originally asked for an offer on certain terms, is an acceptance of a modification of such terms in the offer which is actually made.19 If the offeror acquiesces in an acceptance on the part of the offeree, whereby the offeree refuses to reduce the contract to writing as provided in the terms of the offer, a contract is made by such acquiescence on the part of the offeror in the modification of the original offer thus made by the offeree.20 Where A made an offer to act as agent on certain terms and suggested that it should be put in writing and B replied, "It isn't necessary to have this in writing with me. My word is as good as my bond," A's acquiescence in B's proposition completes the contract.21

If A mails an offer to B in State X, and B attempts to accept such offer in State Y by mailing a so-called acceptance which contains an additional term, and A acquiesces in such additional term in State X, such contract is made in State X and not in State Y.22
