BC Realtor Guide to Backup Offers (2026): How They Work and When to Use Them
A backup offer is one of the most underused tools in BC real estate. When a property your buyer loves is already under contract, submitting a backup offer can secure their position without waiting for the property to relist. When you represent a seller with a conditional offer, accepting a backup offer creates leverage to motivate the primary buyer. This guide covers the mechanics, contract language, deposit handling, and strategic use of backup offers in BC.
How Backup Offers Work in BC: The Basic Mechanics
A backup offer is a fully executed Contract of Purchase and Sale between the seller and a second buyer, containing a clause that makes it conditional on the collapse of the primary accepted offer. It is not a letter of intent, a reservation, or an informal agreement — it is a binding contract with a specific trigger condition.
The Lifecycle of a Backup Offer
1. Primary offer accepted
The seller has accepted a first offer. The property shows as subject to existing offer on the MLS, but may still be available for backup offer negotiations.
2. Backup offer negotiated and accepted
A second buyer submits an offer. The seller accepts it subject to the backup clause: the offer becomes the operative contract if the primary deal collapses before completion.
3. Backup buyer pays deposit
The backup buyer deposits funds in trust (typically with the listing brokerage, as with any deposit). This signals commitment and is returned if the backup never activates.
4a. Primary deal completes
If the primary buyer removes subjects and completes the transaction, the backup offer never activates. The backup buyer's deposit is returned in full.
4b. Primary deal collapses
If the primary buyer's subjects are not removed (or removed with a subsequent default), the primary contract falls. The backup offer activates automatically — no new offer or acceptance required.
5. Backup buyer notified and timeline restarts
Once activated, the backup offer becomes the primary contract. If the backup offer has its own subject removal period, that clock starts on the activation date.
The 72-Hour Clause: How Backup Offers Create Leverage
The BCREA Contract of Purchase and Sale includes a Schedule A provision known as the 72-hour clause (or first right of refusal clause). This clause activates when the seller receives a backup offer while the primary offer has outstanding subjects.
How the 72-Hour Clause Works
Step 1: Primary offer accepted with subjects (financing, inspection, etc.) pending.
Step 2: Seller receives and accepts a backup offer. The backup offer activates the 72-hour clock for the primary buyer.
Step 3: The seller notifies the primary buyer that a backup offer has been received. The primary buyer has 72 hours (or the time specified in the contract) to either remove all subjects and firm up their deal, or allow their contract to terminate.
Step 4a: Primary buyer removes all subjects within 72 hours → their deal proceeds, backup offer never activates, backup deposit returned.
Step 4b: Primary buyer cannot or will not remove subjects within 72 hours → their contract terminates, backup offer activates as the new primary contract.
⚠️ The 72-Hour Clause Must Be in the Original Contract
The 72-hour clause only applies if it was included in the primary offer — either through Schedule A or a special condition. If the primary contract does not have a 72-hour clause, the seller cannot use a backup offer to accelerate subject removal. The clause must be negotiated and agreed to at the time of the original offer acceptance.
For listing agents, always consider including a 72-hour clause in accepted conditional offers — especially in markets where deals are likely to collapse or where other buyers may be interested. It gives the seller optionality without abandoning the primary buyer.
Deposit Handling for Backup Offers
When the Backup Is Never Activated
If the primary deal completes successfully and the backup offer never activates, the backup buyer's deposit must be returned in full without interest or deduction. This is a straightforward return from trust. The backup buyer has taken on no risk other than the opportunity cost of having their funds in trust during the waiting period.
When the Backup Activates
When the primary deal collapses and the backup activates, the backup buyer's deposit transitions into the standard purchase deposit for the now-primary contract. All the normal rules about deposits apply going forward: the deposit is held in trust until completion and credited against the purchase price.
When the Backup Buyer Walks Away After Activation
Once the backup offer activates, the backup buyer is bound by the contract. If they then default — by refusing to remove their subjects or failing to complete — the same consequences apply as with any defaulting buyer:
- • The seller may be entitled to keep the deposit as liquidated damages
- • The seller may sue for additional damages beyond the deposit if their losses exceed it
- • The buyer's credit and reputation may be affected
Some backup offers include a walk-away period after activation — a short window (often 24–48 hours) during which the backup buyer can confirm their commitment or withdraw without penalty. This is a negotiated term, not a default right.
Drafting a Backup Offer: Key Contract Terms
A backup offer is a standard BCREA Contract of Purchase and Sale with an additional clause specifying its conditional nature. Here are the key terms that must be precisely drafted:
Backup Condition Clause
"This Contract of Purchase and Sale is conditional upon the collapse of the Contract of Purchase and Sale currently accepted by the Seller dated [DATE], for the purchase price of [$AMOUNT] (the 'Primary Contract'). This Contract shall automatically become the operative Contract upon written confirmation by the Seller that the Primary Contract has been terminated. In the event the Primary Contract completes, this Contract shall be null and void and the Buyer's deposit shall be returned without interest or deduction."
Deposit Return Provision
"The Buyer's deposit of $[AMOUNT] shall be held in trust by the Listing Brokerage and returned to the Buyer in full within [5] business days in the event this Contract does not become operative by reason of the completion of the Primary Contract."
Activation Notice Period (Optional)
"Upon written notification from the Seller that the Primary Contract has been terminated, the Buyer shall have [48] hours to confirm in writing their intention to proceed under this Contract. Failure to confirm within this period shall render this Contract null and void and the deposit shall be returned."
Subject Removal Timeline After Activation
"In the event this Contract becomes operative, the Buyer's subject removal period shall be [X] days from the date of written notification from the Seller that the Primary Contract has been terminated, rather than from the acceptance date of this Contract."
Completion and Possession Dates
"If this Contract becomes operative, the Completion Date shall be [DATE] and the Possession Date shall be [DATE], unless otherwise mutually agreed upon in writing. [Note: These dates must be realistic given the potentially unknown activation timing.]"
🚨 Always Have Your Managing Broker Review
Backup offer clauses vary in complexity and the specific wording materially affects the rights of both parties. The examples above are illustrative, not BCREA-approved standard language. Always review backup offer clauses with your managing broker before presenting them to clients.
The Practical Challenge: Completion and Possession Dates
The biggest logistical challenge with backup offers is the uncertainty around completion and possession dates. When you write the backup offer, you don't know when (or whether) it will activate. This creates a timing problem:
Problem: Fixed dates may be impossible to meet
If you set a completion date of November 1 and the backup activates October 28, the buyer has three days to arrange financing approval, conveyancing, and fund transfer. This is almost always impossible. If the primary deal was expected to complete November 1 but collapsed a month earlier, the backup buyer may need to negotiate a new completion date at the point of activation.
Solution: Floating completion dates
Some backup offers use a floating completion date — specifying that completion will be X days after activation (e.g., "30 days from the date of written notification that the Primary Contract has been terminated"). This gives both parties predictability regardless of when the backup activates.
Alternative: Negotiated amendment upon activation
Some backup offers include a provision requiring both parties to negotiate and agree on completion and possession dates within X hours of the activation notice, with a fallback date if they cannot agree. This provides flexibility but adds a point of potential dispute.
Strategic Advice: When to Use Backup Offers
Advising a Buyer to Submit a Backup Offer
Good candidates:
- • Property they love and would be difficult to replace
- • Primary offer has multiple subjects or a long subject period (higher collapse risk)
- • Market is moving and waiting for a relist means competing with new buyers
- • Buyer is pre-approved and ready to move immediately if activated
- • Buyer can commit funds to deposit for an uncertain period
Poor candidates:
- • Buyer has their own home to sell and can't firm up quickly if activated
- • Buyer's financing is conditional and may not be approved quickly enough
- • Property is easily replaceable — energy better spent on new listings
- • Buyer uncomfortable with open-ended commitment
Advising a Seller to Accept a Backup Offer
Good candidates:
- • Primary offer has weak financing or multiple subjects (collapse is plausible)
- • Backup price is acceptable and terms are strong
- • Primary buyer is wavering or communicating hesitation
- • Market is slowing — a relisting may result in a lower price
- • Seller wants leverage to accelerate primary buyer's subject removal
Cautions:
- • Backup offer negotiations can distract from the primary deal
- • Backup buyer may lose interest during the waiting period
- • If primary completes, seller is obligated to return backup deposit promptly
- • Dates in the backup offer may be impossible to meet
Advisory Scripts
Buyer who missed out on a property — suggesting a backup offer
"I know it's disappointing, but I want to show you one option before we move on. The property is under contract, but there's typically a window where the seller may accept a backup offer. If the current buyer can't firm up — their financing falls through or their inspection uncovers something — a backup offer would put you automatically in position to buy without waiting for the property to relist. Your deposit would be held in trust and returned in full if the primary deal completes. It's not a guarantee, but it keeps you in the game without the stress of another competing offer situation. Would you like to explore it?"
Seller with a conditional offer — recommending they consider backup offers
"Your buyer has a 14-day subject period, which is a fair amount of time. During that window, I'd suggest we continue to allow showings and be open to a backup offer if another strong buyer comes along. A backup offer doesn't interfere with the primary deal — but it does give us a safety net if the first buyer can't firm up. It also gives the primary buyer a little motivation, because they'll know another offer is in place. Your deposit is only at risk if the primary deal completes — in that case, we return it immediately. Would you want me to continue showing the property with that strategy in mind?"
Buyer asking what happens if they get tired of waiting
"That depends on exactly how the backup offer is written. If the contract includes a walk-away window after notification — say 48 hours — you'd have a chance to confirm or withdraw at that point. If there's no such window, the backup is binding once it activates. Before we sign, we should add language that gives you a short window to confirm after the primary deal collapses — just in case your circumstances change during the waiting period. I'll include that in the clause."
Explaining the 72-hour clause to a primary buyer who just received notice
"The seller has received a backup offer, which triggers the 72-hour clause in your contract. This means you have 72 hours to remove all your subjects — financing, inspection, whatever we have outstanding — and firm up the deal. If you can't or don't want to, the contract terminates and the backup buyer steps in. I want to be clear: this is a real deadline. We need to move on your financing confirmation and inspection review right now. Can we connect with your broker today?"
Frequently Asked Questions
What is a backup offer in BC real estate?
A backup offer is a signed, accepted offer to purchase a property that becomes the primary contract automatically if the existing accepted offer collapses — typically due to the primary buyer failing to remove subjects. The backup buyer agrees to purchase the property at the agreed price and terms, with a clause specifying the conditions under which it becomes the operative contract.
Does the backup buyer pay a deposit in BC?
Yes, the backup buyer typically pays a deposit when the backup offer is accepted. This deposit is held in trust. If the primary deal collapses and the backup offer activates, the deposit is applied toward the purchase. If the backup offer never activates (the primary deal completes successfully), the deposit is returned to the backup buyer without interest or penalty.
Can a seller accept multiple backup offers?
Technically a seller could accept more than one backup offer (a second backup and a third backup), but this creates significant complexity and potential liability. Most BC transactions involve at most one backup offer. If a seller wants to establish a priority queue among multiple backup offers, each backup offer must clearly define its position (first backup, second backup) and the trigger conditions.
Can the backup buyer walk away before the backup activates?
This depends on how the backup offer is written. Some backup offers include a time-limited acceptance period that gives the backup buyer a window to confirm or withdraw after being notified that the primary deal has collapsed. Others bind the backup buyer immediately upon activation. The contract terms control — buyers should understand exactly what they are committing to before signing a backup offer.
Should sellers tell buyers they have a backup offer?
BC law does not require sellers to proactively disclose that a backup offer exists. However, the BCREA Contract of Purchase and Sale includes the 72-hour clause (Schedule A), which triggers when a backup offer is received — this clause is what notifies the primary buyer that a backup has been received and starts the clock. The existence of a backup offer is therefore typically communicated through the 72-hour clause mechanism.
