Communication
The transmittal of information, offers, acceptances, or notices between parties; how and when communications are made affects offer/acceptance timing, notice effectiveness, and contract formation.
While straightforward in theory, many businesses fail to actively track obligations tied to this concept - often resulting in missed deadlines, unintended renewals, penalties, or loss of contractual rights.
US Law · For business owners and foundersWhat is a Communication?
Communication in contract law refers to the transmission of information, proposals, acceptances, rejections, notices, or other contractually significant statements between parties. Without communication, a contract cannot form. The law recognizes that communication can be oral, written, electronic, or by conduct, and that the timing and method of communication critically affect contract formation, obligations, and enforcement.
When you make an offer (a proposal to be bound by specific terms), you must communicate it to the other party. The other party accepts by communicating acceptance back to you. If the communication never reaches the intended recipient, or if it is ambiguous, contract formation may be delayed or fail entirely. Courts use an objective "reasonable person" test: would a reasonable party, given the words and circumstances, understand that a binding offer or acceptance was being made?
The method and timing of communication also matter for notices and performance deadlines. A contract that requires "notice within 30 days" depends on when notice is communicated. Some contracts specify that notice is effective when sent (mailbox rule); others require actual receipt. These rules prevent parties from claiming ignorance and provide certainty about when contractual obligations are triggered.
In practice, many teams rely on a contract expiry tracking system to stay on top of dates and obligations tied to clauses like this.
Key Elements
Transmission of Offer
An offer must be communicated to the offeree. Communication can be direct (to a specific person) or general (to the public, as in advertisements). The offer must contain material terms and evince a serious intent to be bound.Communication of Acceptance
Acceptance must be communicated back to the offeror in a manner that reasonably indicates agreement to the terms. Silence does not constitute acceptance unless the parties have agreed otherwise or the offeree benefits from services with opportunity to reject.Timing and Receipt
For most contracts, the "mailbox rule" applies: an acceptance is effective when sent, not when received. This creates a binding contract even if the offeror has not yet received the acceptance. However, the contract terms may alter this default rule.Method of Communication
The method must be reasonable given the circumstances. If an offer specifies how acceptance must be communicated (e.g., "reply via email by noon Friday"), the offeree must comply. Otherwise, any reasonable method is acceptable.Notice and Notices Clauses
Contracts often require written notice for termination, breach, or exercise of remedies. The notice provision specifies how notice must be delivered (by mail, email, hand delivery) and to what address. Strict compliance is usually required.Real-World Example
A vendor sends a written quote to a customer via email: "I can supply 100 units of widgets at $10 each, delivery in 30 days. This offer expires Friday at 5 PM." The customer receives it Thursday, has a question, calls the vendor to ask about payment terms, then replies via email Friday at 4 PM saying "I accept your offer." The vendor does not check email until Monday and claims the offer had expired.
Communication rules resolve this dispute. The written quote is a valid offer. The customer's phone call does not constitute acceptance (it was an inquiry). The customer's email acceptance on Friday at 4 PM is communicated before the Friday 5 PM deadline. Under the mailbox rule, the acceptance is effective when sent (Friday 4 PM), even though the vendor did not receive it until Monday. The contract is formed.
This is why many businesses adopt automated deadline tracking to ensure no critical dates are missed before they pass.

Notice ProvisionWatch Out For
Ambiguity about when communication is "effective"
If your contract requires "prompt notice" or "notice within 30 days" but does not define when notice is effective (sent vs. received), disputes arise. Courts default to the mailbox rule, but clarity prevents litigation.Email is not automatically received
Sending an important notice via email is risky if not confirmed. Email can go to spam, servers can delay delivery, and the recipient can later claim they never saw it. Use tracked email, read receipts, or require signed acknowledgment for critical notices.Silence is not acceptance
Do not assume that a recipient's lack of response to an offer means they accept. Courts generally require affirmative communication of acceptance. Silence is not binding unless the parties' prior dealings or trade custom suggest otherwise.Conditional or qualified acceptance is a counteroffer
If you say "I accept, but only if you change the price," that is not acceptance - it is a counteroffer that rejects the original offer. Courts scrutinize qualified responses that try to preserve the deal while changing terms.Don't let communication deadlines catch you off guard
Key dates tied to communications - renewal windows, expiry cutoffs, notice periods - can easily slip through the cracks when tracked manually. Missing them triggers automatic extensions, penalties, or lost rights. ExpiryEdge tracks every critical deadline and sends automated reminders before they're due - so nothing slips.
Instead of relying on spreadsheets or manual follow-ups, a centralized renewal reminder system ensures every deadline is visible, tracked, and actioned automatically.
How to Use This in Your Favor
Use tracked, confirmed communication for critical notices
For termination, breach notices, or exercise of remedies, use email with read receipt, overnight courier, or hand delivery with signed acknowledgment. This creates a record that the communication was sent and received.Specify the method and effect of notice
In your contract, state exactly how notice must be delivered (email to [address], mail to [address]) and when it is effective (upon receipt or upon sending). This prevents arguments about whether the other party actually saw it.Use affirmative acceptance mechanisms
If you want to ensure acceptance, do not rely on silence. Use clickwrap agreements, signed acknowledgments, or explicit "I agree" buttons. This creates clear evidence of communication and acceptance.Related Terms
Frequently Asked Questions
Is an email offer binding?
Yes, if it contains all material terms and the sender intends to be bound. An email quote, if specific enough and evincing serious intent, can be an enforceable offer. The question is whether a reasonable party would view it as a binding proposal, not just a preliminary discussion.
What if I send an acceptance but the other party never receives it?
Under the mailbox rule (the default in most jurisdictions), your acceptance is effective when you send it, even if never received. A contract is formed. However, you should have evidence of sending (email confirmation, certified mail, etc.) to prove it.
Can I revoke an offer after I send it?
Generally, no. Once you communicate an offer and the other party receives it, the offer stands until the stated deadline. You can revoke before acceptance is communicated, but revocation itself must be communicated. If acceptance has already been sent, it is too late.
