How an Offer Moves Back and Forth — and When It Becomes Binding
Offers are not “negotiations in progress” — they are time-sensitive legal documents.
This page explains how a Residential Purchase Contract moves between buyer and seller, how counter-offers are created, and what REALTORS® must do to ensure the contract is valid, enforceable, and properly executed.Â
Throughout the purchase contract, certain words and phrases are capitalized (e.g., Property, Buyer, Seller, Completion Day, Deposit).
Capitalized terms:
have specific legal meanings
refer back to defined sections of the contract
must be read consistently throughout the document
This is standard legal drafting practice and helps:
avoid ambiguity
ensure consistent interpretation
strengthen enforceability
👉 REALTORS® should not alter defined terms casually and should ensure clients understand that capitalized terms are intentional and meaningful.
The buyer submits a signed offer to the seller that includes:
price and deposit
conditions
timelines
all agreed-upon terms
At this point:
the offer is open for acceptance only until the expiry date and time
the buyer is legally bound if the seller accepts without changes
The seller has three options:
Accept the offer as written
Reject the offer
Counter the offer
Any change — no matter how small — creates a counter-offer, including:
crossing out wording
changing dates or amounts
adding or removing clauses
altering conditions
Once a counter-offer is made:
the original offer is no longer available
the roles reverse — the seller becomes the “offeror”
A counter-offer must:
clearly show all changes
have every change initialed by all parties
be signed and delivered before the stated expiry
⚠️ If changes are made but not initialed by all parties, the contract may be unenforceable.
Initials serve a critical legal purpose:
they confirm agreement to each specific change
they reduce disputes over “who changed what”
they support enforceability if challenged later
Best practice
Initial beside every strike-through, insertion, or amendment
Never assume a signature alone confirms agreement to changes
Do not rely on “verbal approval” of changes
Every offer and counter-offer has an expiry date and time.
If the offer is:
not signed
not fully initialed
not delivered
before the expiry, it is void.
Once expired:
there is nothing to accept
a new offer must be prepared
This applies even if:
the parties intend to proceed
negotiations were ongoing
the delay was minor
Time is of the essence.
REALTORS® must:
track expiry dates and times precisely
confirm time zones (Alberta time governs)
ensure all changes are properly initialed
confirm execution before expiry
avoid presenting expired or incomplete offers
REALTORS® should never:
assume flexibility on expiry
backdate or alter times
pressure parties to “just sign quickly” without review
Changes made after expiry
Missing initials beside amendments
Confusion over which version is current
Multiple counters circulating simultaneously
E-signature time stamps not aligned with Alberta time
When in doubt:
stop
clarify
escalate to the brokerage or legal counsel
Any change = counter-offer
Initials matter — every time
Expiry dates are absolute
Execution must be complete and delivered before expiry
