Two Contracts, One Settlement Date: What If One Slips
You have exchanged on both a sale and a purchase for the same date. What happens when one slips, who bears the cost, and can finance still complete.

You have exchanged on both a sale and a purchase for the same date, and one side is now looking shaky. This page separates the two contracts: which side slipping hurts more, whether you can extend one without breaching the other, whose deposit is exposed, whether short-term finance can still complete the purchase, and what happens to your sale once it does.
Quick Answer
When a sale and a purchase are written for the same date and one of them slips, the two contracts do not move together, because each is a separate agreement with its own counterparty. Which side slips decides who is exposed.
Part of the bridging finance guide, alongside guide to buying before selling.
If your sale slips: your buyer is late paying you, and you are the party who cannot complete the purchase. The breach lands on your contract, not theirs.
If your purchase slips: your vendor is not ready, your sale can usually still complete, and you are the innocent party holding the proceeds while the other side runs late. The buying before selling guide covers how the two are ordered when they do run on 1 day.
Also called: linked settlements, same-day sale and purchase.
What happens when you have exchanged on both a sale and a purchase for the same date?
Nothing joins the two contracts except you. The mechanics of the day itself, the order the money moves in and what the linking clause does, are covered in the companion piece on a simultaneous settlement; this page covers what happens contractually when the pair comes apart. You are the buyer on one agreement and the seller on the other, the parties on the far side of each have never met, and neither contract contains a promise about the other. The same date in both documents is a coincidence you arranged, and it holds only while every party performs.
That matters because the date itself is negotiated rather than imposed. Each contract fixes its own completion date and its own consequences for missing it, which is why two agreements written for 1 day can come apart on that day without either party doing anything unusual.
Set in the contract, not by lawConsumer Affairs Victoria states that the seller sets the date in the contract of sale and that "the settlement period is usually 30 to 90 days and can be negotiated with the buyer".

The other thing worth counting is how many parties can be late. Your buyer has their own lender and their own conveyancer, your vendor has a discharge to arrange with their lender, and each of those is a separate queue with its own cut-off. A same-day pair is not one transaction with one risk. It is two exposures that happen to share a calendar entry, and the funding question only arrives after one of them moves. Where the money has to be ready earlier than the contracts assume, the fast completion finance guide sets out what can actually be arranged at short notice.
Which side slipping hurts more, your sale or your purchase?
Your sale slipping hurts more, because it is the side that leaves you unable to perform on the other contract. If your buyer's funds are not there, the money you promised your vendor is not there either, and the party in default on the purchase is you. Nothing about your buyer's failure transfers to your vendor, who is entitled to be paid on the date you agreed.
Your purchase slipping is the gentler failure. If your vendor cannot complete, your sale can usually still go ahead, you receive the proceeds, and you are the innocent party on the contract that failed. The problems are practical rather than contractual: where you and your possessions go, and where the proceeds sit in the meantime.
| What slips | Effect on your sale contract | Effect on your purchase contract | Who is exposed |
|---|---|---|---|
| Your buyer is late, so your sale slips | You are the innocent party. The contract sets out what you can charge or claim, and what notice you can serve | Unchanged and still due. Your vendor is owed the full balance on the agreed date | You, on the purchase, for a failure that happened on the sale |
| Your vendor is late, so your purchase slips | Unaffected. Your buyer's obligation to pay you does not depend on your vendor | You are the innocent party, with the contract's remedies against your vendor | Mainly your vendor, though you carry the practical cost of having sold and not bought |
| Both run late on the same day | A claim may run against your buyer | A claim may run against you at the same time | You, on both sides at once, which is the case for keeping the two dates apart by agreement rather than by accident |
| Your own funder is not ready | Usually unaffected, because your buyer funds that side | You cannot complete, and the reason is not one your vendor has to accept | You, and this is the one you can do something about in advance |
Illustrative only. What each contract actually allows depends on its own terms and the state it was written in.
There is a published answer to this question that is worth correcting. The answer panels currently split the outcome by which side slips, then assume the rescue comes from your own bank releasing emergency funds at a few days notice. That is the one lender least able to do it. A major bank assessing a new facility works to its own credit timetable, and a same-day problem does not shorten it, which is why the practical answer sits with funders who price and settle short-term positions as their ordinary business.
Can you extend one contract without breaching the other?
You can extend one contract without breaching the other, but only the parties to that contract can agree to it, and the extension does not travel across to the second agreement. Moving a linked pair therefore takes two consents, not one, and they have to be obtained in the right order or you simply relocate the breach.
The order that works is to fix the purchase first, because that is the contract you can default on. If your vendor will agree to a short deferral, your exposure drops immediately and the conversation with your buyer becomes a commercial one rather than an urgent one. If your vendor will not agree, granting your own buyer an extension is a decision to accept the consequences on your purchase, and it should be made with that price in view. Whether the vendor charges for the deferral, and what a contract can charge for lateness, is covered in the penalty interest guide.
The common failure is that one side agrees informally and nobody documents it. An agreed change of date is a variation of the contract, usually recorded as a deferred settlement, and an email between agents is not the same thing. If a formal notice has already been served on either contract, the deadlines in that notice run on their own timetable, which the notice to complete guide sets out state by state.
Whose deposit is exposed when the two contracts are linked?
Two deposits sit inside a linked pair, and the one at risk is the deposit you paid, not the one you hold. Your buyer's deposit is held on your sale, usually in a trust account, and it is security for their performance to you. Your own deposit is held on your purchase and is security for your performance to your vendor. When your buyer is late and you cannot complete, the deposit under threat is yours.
The New South Wales Government's guidance on contracts and deposits, read 14 September 2026, sets out the same structure from the buyer's side, including when a deposit becomes payable and what the contract does with it. That asymmetry is the reason the pair feels unfair to the person in the middle. You can be entirely blameless on the contract that failed and still be the only party whose money is at risk on the contract that did not. Reading the default provisions of your purchase contract before the date, rather than on it, is the cheapest hour available in this whole situation, and it is a solicitor's reading rather than a broker's.
The other exposure to check early is the size of the balance itself. If a lender's what a low valuation does at settlement on either property comes in under the contract figure, the funds you need on the day move even though neither contract has changed, and that gap has to be found from cash or from another facility. The valuation shortfall guide covers where those funds usually come from.
Can short-term finance complete the purchase while the sale catches up?
Short-term finance can complete the purchase while the sale catches up, and that is the ordinary way this is solved once a linked pair has come apart. The facility is secured against the property being sold, the property being bought, or both, it funds the balance owing to your vendor, and it is repaid when the sale finally completes. What it is not is an emergency product from your existing bank.
What lenders actually look at first
- The exchanged sale contract, because a signed contract with a real buyer is the strongest evidence of repayment there is
- Equity across both properties, measured against the debt already registered on each
- Whether the delay has a cause and an end date, or is open ended
- The exact amount needed on the day, including duty, adjustments and the cost of the facility itself
Indicative of what is commonly assessed on this lane. Criteria, pricing and timing vary by lender and by deal, and none of it is a quote.
Timing is the part borrowers get wrong in both directions. Non-bank and private funders can work to a date measured in days rather than weeks where the security is clean and the exit is documented, but they still need a valuation, searches and executed documents, and a request made the afternoon before completion is a different conversation from one made a week out. The short-term security options guide sets out which structure suits which position, and the shortfall at completion piece covers the smaller version of the same problem. If you want the position assessed rather than described, check eligibility with the two contracts in front of you.
| Cost that appears | On your sale contract | On your purchase contract |
|---|---|---|
| Compensation for the delay itself | Payable to you by your buyer, on the terms of that contract | Payable by you to your vendor, whether or not your buyer ever pays you |
| The cost of agreeing a new date | Your decision to grant, and your price to set | Your vendor's decision to grant, and your vendor's price to set |
| The cost of funding the gap | Not a cost of this contract, though the proceeds repay it | Yours, as the party who has to produce the money on the day |
| Holding costs while the pair is unresolved | Yours, because you still own and still insure the property you are selling | Yours, once the facility is drawn and the property is bought |
| Losing the transaction entirely | Your buyer's deposit and your claim against them, if it comes to that | Your deposit and your vendor's claim against you, on their terms |
Illustrative only, and scoped to a pair of linked contracts. Every entitlement here comes from the wording of the particular contract.
Once a bridge funds the purchase, what happens to your sale?
Your sale still has to complete, and once a short-term facility has funded the purchase, that sale is no longer just a transaction. It is the repayment. The funder has taken the exchanged contract as its exit strategy, priced the facility on the expectation that those proceeds arrive, and will be paid out of them when they do.
Two things follow from that. The first is that the facility keeps running while the sale does, so a buyer who is late a second time costs you more than they did the first time, and the arithmetic is a daily one. The second is that your funder is now an interested party in a contract it is not on. Telling it early that the date has moved is not a courtesy, it is how a short extension stays a short extension rather than becoming a refinance.
The sale usually completes and the facility is discharged out of the proceeds without drama, because the buyer who caused the first delay had a fixable problem rather than a fatal one. Where the sale does not complete at all, the question changes from timing to exit and belongs in a different conversation. If you want the wider shape of this before you commit to either contract, the buying before selling guide is the place to start, and the property lending hub holds the rest of the lane.
Where the two contracts sit in different states, the standard forms and the conventions around the date are not the same on both sides, which is covered in the piece on a bridging loan when you are moving interstate.
A sale and a purchase written for one date are two contracts, not one transaction, and the machinery that makes them feel joined is only your own money moving between them. When the sale slips you are exposed on the purchase; when the purchase slips you are mostly inconvenienced. An extension has to be agreed on each contract separately, the deposit at risk is the one you paid, and short-term finance can complete the purchase and wait to be repaid from the sale, provided it is arranged with days rather than hours in hand.
Key takeaway: fix the contract you can default on first, then negotiate the one where you are owed.Frequently Asked Questions
A delayed electronic settlement means the workspace does not complete at its booked time, and where two workspaces are linked the second cannot draw the funds it relied on. The platform's own material defines a linked settlement, described in the insight on a simultaneous settlement, as one where destination funds from one settlement are the source funds in another, but not what happens when one side is not ready. What follows is decided by the contract for the workspace that failed, including any right to a further attempt that day and any compensation.
Only by agreement with the buyer on that contract, or where the contract itself gives a right to extend, because the date is a term of the agreement rather than a statutory period. If you are selling and buying on the same date, agreeing to your buyer's request moves your sale but not your purchase, so the two dates come apart unless your own vendor agrees to the same change. Where both sides agree, the change is usually documented as a deferred settlement rather than left as an understanding between agents.
A seller who cannot complete on the agreed date puts the buyer in the innocent party's position, and the buyer's remedies come from the contract, commonly interest or compensation and, after a formal notice, termination. If that seller is your vendor and you are also selling on the same day, your sale can usually still complete, because your buyer's obligation to you is not affected by what your vendor does. Deadlines by state and what a served notice does are in the notice to complete guide.
You can complete a purchase before the related sale completes, provided the money to do it comes from somewhere other than the sale proceeds, which usually means equity released against one or both properties through a short-term facility. The funder then treats the exchanged sale contract as the exit and is repaid when that sale completes. The order the funds move in on a same-day arrangement, and what changes when they are separated, is set out in the buying before selling guide.
Your buyer's delay does not excuse you on your purchase, because your vendor is not a party to your sale contract and has no obligation to wait for money that was never promised to them. That is the whole risk in a linked pair: you carry the consequence of someone else's lateness on a contract they have never seen. Practically, the choices are an agreed extension with your vendor, funding the completion from a short-term loan against property you already own, or accepting the consequences your purchase contract sets out for failing to complete.
