Late receipt of a declaration of acceptance

If a declaration of acceptance received late by the offeror was sent in such a way that it would have reached the offeror in good time had it been forwarded in the usual way, and if the offeror ought to have recognised this, then the offeror is to notify the acceptor of the delay following receipt of the declaration without undue delay, unless this had been done already previously. If the offeror delays the sending of the notification, the acceptance is deemed not to be late.
