By the time a resale private home in Singapore reaches completion, the price has been agreed for weeks and the deposit has long been paid. What remains looks like paperwork: a date, a balance, a set of keys. Yet most of the money moves on that one day, and the contract has an answer for much of what can go wrong around it, from an unpaid tax bill to a buyer whose funds arrive a week late.

Those answers sit mostly in a document few buyers or sellers ever read: the Law Society of Singapore's Conditions of Sale, which options and sale agreements adopt by reference. This guide works through the 2020 edition condition by condition, for the weeks before completion, the day itself and the aftermath of a missed date, and sets beside it five published court decisions that show how these conditions, or earlier editions of them, have been applied. Only some of those decisions concern the resale of a private home; each is described below as what it was. It also draws on the Central Provident Fund Board's terms for using savings on a home. It describes the position as read in October 2026. It does not retrace the option stage, and it is a description of standard terms, not of any one contract.

Law Society of Singapore, Conditions of Sale 2020, conditions 9.1, 9.2, 9.6 and 15.7.

Which conditions govern, and what overrides them

The Conditions of Sale 2020 define their own reach. A "Contract", in condition 1, is a document evidencing a sale by private treaty, auction, tender or otherwise, and the definition expressly includes an option that has been exercised. So a buyer who exercised an option that adopts the conditions is bound by them from that moment.

They are a default layer, not the last word. Condition 17 provides that special conditions in the contract prevail over the standard conditions wherever the two conflict. Anything said below about the standard conditions therefore yields to what a particular contract says.

The edition matters as well. The five decisions used in this guide applied three sets: the 1999 conditions in [2011] SGHC 236, [2012] SGHC 88 and [2013] SGHC 203, the 2012 conditions in [2023] SGHC 1, and the 2020 conditions in [2026] SGDC 16. Late completion interest sat in condition 8 of the 1999 set and the notice to complete in condition 29; in the 2020 set they are conditions 9 and 15.

The properties differ too. [2013] SGHC 203 concerned a private residential property. [2012] SGHC 88 concerned a public housing (HDB) flat, [2011] SGHC 236 a commercial unit in a public housing block, and [2023] SGHC 1 a condominium unit sold by its developer under a sale agreement that prevailed over the conditions. They are used here for how the courts read the standard wording, not as examples of a private resale. The judgments in [2011] SGHC 236, [2012] SGHC 88 and [2013] SGHC 203 note that appeals were filed, and [2023] SGHC 1 was under appeal when read; the outcomes were not read for this guide.

Three definitions in condition 1 carry much of the weight. The Scheduled Completion Date is "the day fixed for completion under the Contract or as subsequently varied". The Completion Date is the day on which completion actually takes place. And a Business Day is any day other than a Saturday, a Sunday and a public holiday. If the Scheduled Completion Date falls on a day that is not a Business Day, it moves to the next Business Day, and condition 1 says this holds even where the contract uses the words "within" or "on or before". The conditions as read do not fix a place or a time of day for completion; those come from the contract.

A countdown to the scheduled date

Most of the deadlines in the conditions are counted backwards from the Scheduled Completion Date, and most of them fall on the vendor. Read together, they form a timetable for the final month.

The first line concerns title. Under condition 3, once the documents are provided the purchaser is treated as having full notice of what they contain, and the vendor bears the cost of producing documents held by a mortgagee.

The second concerns income tax. Where a vendor is not resident and the gain from the sale is taxable under section 10(1)(a) of the Income Tax Act, condition 7.3 requires the vendor to let the purchaser deduct withholding tax and pay it to the Comptroller. That liability is presumed unless the vendor tells the purchaser otherwise not later than two weeks before the scheduled date, and a vendor who stays silent must indemnify the purchaser for any loss.

The third, the mode of payment, is the vendor's statement of how the balance is to be split and to whom it is to be paid. A Singapore law firm, Fortis Law Corporation, wrote in an article published on 19 November 2025 that this notice period was five clear business days in the 2012 conditions and became seven in the 2020 set.

The fourth concerns seller's stamp duty. The vendor notifies the amount, with a certified declaration and any certificate of payment. If the vendor fails to pay the duty, condition 7.4.2 allows the purchaser to deduct the duty and any penalties from the purchase price and pay them, and that payment counts as payment to the vendor.

The state of the home, vacant possession and risk

Two short conditions decide what the buyer is entitled to find on the day. Under condition 5.1, the vendor must deliver the property in the state it was in at the date of the option or the date of the contract, whichever is earlier, "save for fair wear and tear", unless the parties agree otherwise. Under condition 5.2, where the contract provides for vacant possession, all movable property not included in the sale must be removed by completion, again unless the parties agree otherwise.

Against these stands condition 8: subject to conditions 5 and 10, the purchaser is deemed to know the actual state of the property. The District Court in [2026] SGDC 16 quoted its reach as extending to "access, repair, light, air, drainage".

The decisions show where keys appear: in the documents the parties add. In [2013] SGHC 203, a purchaser who was allowed to move in before completion signed a letter of indemnity that required the delivery of "vacant possession and all keys" to the property.

What "fair wear and tear" costs when it is exceeded was tested in [2023] SGHC 1, a developer's sale of a condominium unit under the 2012 conditions, where the sale agreement required a purchaser allowed into early possession to reinstate the unit, fair wear and tear excepted. The court noted that a partition wall, additional doors and cabinets and electrical modifications had been left in place, held that the burden of proving fair wear and tear lay on the purchaser under that clause, and allowed reinstatement costs of S$103,915.48.

Risk follows possession. Condition 13 keeps the risk in the property with the vendor and passes it to the purchaser on completion or on the purchaser taking possession, whichever is earlier.

Splitting property tax, maintenance and other outgoings

Condition 6 draws a single line through every recurring cost, and the line is the Scheduled Completion Date. The vendor is entitled to the rents and profits and is liable for all expenses, outgoings and levies down to and including that date. The purchaser is liable for them, and entitled to the rents and profits, after it.

Property tax has its own condition. Under condition 7.1, the vendor pays all property tax down to and including the Scheduled Completion Date, "whether levied or increased before, on, or after" completion, and indemnifies the purchaser for any such tax the purchaser has to pay. Condition 7.6 confirms that these tax conditions survive the conveyance.

One case has a mechanism of its own. If the Chief Assessor has not yet included the property on the valuation list, condition 7.1.3 has a reasonable sum set aside from the sale proceeds and held by the vendor's solicitors as stakeholders, to meet the tax once it is assessed, with any excess returned to the vendor. The conditions do not define a reasonable sum or say how long it is held.

For homes in a strata development, condition 6.3 deals with levies for the common property: the vendor pays lump sums, or instalments, that fall due on or before the Scheduled Completion Date. Condition 12 adds that the vendor must comply with any notice or demand for maintenance or alteration made before that date by a government or statutory body, a lessor, or a management corporation. If that has not been done by completion, the vendor either indemnifies the purchaser for the cost or sets aside a sum from the completion account, held by a stakeholder.

A worked example shows the arithmetic. It assumes a property tax bill of S$3,650 for the calendar year 2026, already paid in full by the vendor, a Scheduled Completion Date of 30 September 2026, and a split by days over a 365-day year. The daily method is an assumption: the conditions state who bears what, not how the sum is computed. From 1 January to 30 September is 273 days, so the vendor's share is S$2,730. The remaining 92 days, S$920, fall to the purchaser, who would reimburse that sum to the vendor at completion.

The money on the day

The conditions describe completion as an exchange. Under condition 14.1, on payment of the balance of the purchase price the vendor and any other necessary parties execute and deliver the conveyance, the instrument that transfers the property. The purchaser prepares that instrument at its own expense under condition 14.2, while the vendor prepares or procures whatever releases are needed to hand over a title free from encumbrances.

Where the money goes is fixed by condition 2. Conveyancing money payable to the vendor's solicitor must be paid into that solicitor's conveyancing account, the CVY Account. A payment made to the solicitor but not into that account remains a valid payment under condition 2.2, and the solicitor must treat it as if it had been paid there. Condition 4 covers the opposite problem: if a payment is dishonoured, the vendor may treat the contract as repudiated and rescind it, or affirm it.

The term "completion account" appears in the conditions once, in condition 12.2, as the pool from which a sum may be set aside, and its form is not prescribed.

Many buyers fund part of the balance from Central Provident Fund savings. The CPF Board's terms and conditions for the CPF Housing Scheme, updated on 7 September 2026, set the frame. Ordinary Account savings may be used to pay the purchase price directly to the seller, to repay the housing loan, and to pay stamp duty and legal fees. They may not be used for option fees, nor to reimburse the member for payments already made personally to the seller. The application reaches the Board through the member's lawyers, the Board may appoint its own lawyer to disburse the savings for completion at the member's cost, and the money is never paid to the member. Before any of it is released, the member must have paid in cash the part of the price not covered by the housing loan and the approved CPF amount, and if the member dies after approval but before release, nothing is released. On release, a charge in favour of the Board attaches to the property at once.

The seller meets the same Board from the other side. Under the same terms, the principal withdrawn plus accrued interest must be refunded on a sale, whatever the member's age, and option money received in cash counts as part of the selling price and must be refunded before completion. If the proceeds left after the housing loan do not cover the refund, no cash top-up is required provided the sale was at market value.

Late completion interest: the rate and when it runs

Condition 9 sets a price for delay, payable as liquidated damages, a sum fixed in advance by the contract. It runs both ways, but not on the same base.

In both directions the interest runs from the day after the Scheduled Completion Date up to and including the Completion Date. As a worked example with illustrative figures, take a price of S$1,800,000, a deposit of S$90,000 already paid, completion ten days late and a 365-day year. The 365-day year is this guide's assumption: the conditions state an annual rate and no day count. If the delay is solely the purchaser's default, the base is S$1,710,000. A year's interest at 8% is S$136,800, or S$374.79 a day, and ten days come to S$3,747.95. If the delay is solely the vendor's default, the base is the full S$1,800,000: S$144,000 a year, S$394.52 a day, and S$3,945.21 for ten days.

The rate has not always been 8%. The 1999 conditions, as quoted by the High Court in [2012] SGHC 88 and [2011] SGHC 236, set it at 10% a year on the purchase price where the vendor was in default. The 2012 text was not read for this guide, so it does not say which edition made the change.

Several conditions switch the interest off or reduce it. If the vendor failed to deliver the mode of payment at least seven clear Business Days before the scheduled date, condition 9.6 relieves the purchaser of interest, for a delay no longer than the number of days by which the notice was late. Under condition 9.7, where a pay-out form has to be countersigned, no interest is payable for a day on which the electronic payment instruction system fails for more than four consecutive hours and the parties have to proceed manually. Under condition 9.3, if the vendor handed over vacant possession early and no rent is payable, the interest the vendor owes is reduced by a notional rent based on the annual value assessed by the Inland Revenue Authority of Singapore.

The vendor also has a choice. When a purchaser cannot or will not complete on time, condition 6.4 lets the vendor decline the interest under condition 9.1 and instead keep the rents and profits of the property, while accounting for outgoings, expenses and levies up to and including the actual Completion Date.

What the courts have called a default

Everything in condition 9 turns on the words "due solely to the default" of one party, and the conditions do not define default. Three decisions fill the gap.

In [2012] SGHC 88, decided on 26 April 2012 under the 1999 conditions, a vendor could not deliver a public housing (HDB) flat with vacant possession free of encumbrances; a caveat had been lodged against it. The High Court said that a contractual duty "is not concerned with fault", found the delay to be solely the vendor's default, and ordered interest at 10% a year from 8 April 2011 until completion, to be deducted from the net sale proceeds.

In [2011] SGHC 236, decided on 31 October 2011, under the same 1999 conditions, the sale of a commercial unit in a public housing block was delayed. The court called the vendor's position "self-induced", held that the no-interest condition is for a vendor who is blameless, and ordered interest at 10% a year from 18 November 2010.

The most recent, [2026] SGDC 16, was decided on 30 December 2025 under the 2020 conditions. The option was exercised on 10 January 2024 with completion due on or before 6 March 2024. The vendor had not obtained access to the property by that date, and the sale completed on 25 July 2024 after a new date was agreed, which is 141 days counted from 7 March by this guide's count. The purchaser claimed S$182,000 in late completion interest, a sum the vendor's solicitors held while the dispute was decided. The District Court held that the failure to secure access by the original date was the vendor's default and dismissed the vendor's application with costs of S$8,000.

The notice to complete

A late completion does not end a contract by itself. Under condition 15.1, the notice to complete procedure applies unless the special conditions make time of the essence for the scheduled date. The notice is the means by which either side can turn a missed date into a final deadline.

One limit applies to the vendor alone. Under condition 15.5, a vendor may not give the notice until five clear Business Days after delivering the mode of payment, or a variation of it.

The dates in [2023] SGHC 1 show the count. The notice was given on 26 July 2021 and required completion by 16 August 2021, which is 21 days counted from 27 July by this guide's count. That case was a developer's sale under the 2012 conditions. The sale agreement was terminated on 17 August 2021.

When a notice to complete is not met

If the purchaser fails to comply, condition 15.9 requires the purchaser to return the title deeds at once and to cancel, at its own expense, anything it has registered against the property. The vendor may forfeit and keep the deposit, and resell the property by auction or private agreement without first tendering a conveyance. Condition 15.10 then deals with the resale: if it takes place within one year after the Scheduled Completion Date, any loss, including the reasonable costs of reselling, is payable by the purchaser as liquidated damages, after credit for the deposit and other sums paid. If the resale brings a surplus, the vendor keeps it.

If the vendor fails to comply, condition 15.11 gives the purchaser a choice between enforcing its rights and requiring immediate repayment of the deposit and all sums paid, without giving up a claim to damages. A purchaser who takes repayment is, under condition 15.12, no longer entitled to specific performance, returns the title deeds and cancels its registrations at the vendor's expense.

Two decisions show the purchaser's side of this in figures. In [2013] SGHC 203, a private home was sold for S$1,850,000 with a 5% deposit of S$92,500. A 21-day notice was served on 9 July 2012 and the vendors rescinded on 3 August 2012. The High Court held that they could keep S$284,500, the deposit together with further deposits paid for extensions, under the forfeiture condition of the 1999 set and, alternatively, at common law. It also ordered rent of S$88,000 for the purchaser's occupation from 26 June 2012 to 17 June 2013, the day the keys came back. In [2023] SGHC 1, the developer's sale of a condominium unit priced at S$3,089,000 with a deposit of S$308,900, the court assessed damages at S$720,960.84 and held that the purchaser could not set the forfeited deposit off against them, because the sale agreement prevailed over the conditions on that point.

Moving the date by agreement

The definition of the Scheduled Completion Date includes the words "or as subsequently varied", so the two sides can move the date. The conditions themselves postpone it in one situation: under condition 9.5, if a party dies or loses mental capacity before the scheduled date, completion may be put back for a reasonable period of not more than three months, so that a grant of probate, letters of administration or a court order appointing deputies can be obtained. No interest is payable by either party during that extension.

A notice to complete can be stretched too. Under conditions 15.13 and 15.14, the party who served it may, at the other's request or with its consent, extend it for one or more stated periods. The extended period replaces the 21 days, and time stays of the essence.

Every other extension is a negotiation, and the decisions show what is usually settled in it: whether interest keeps running.

Extensions granted to a purchaser tend to carry a price. In [2013] SGHC 203, completion was first due on 17 January 2012 and was deferred several times, finally to 6 July 2012. Each deferral came with conditions: additional deposits that totalled S$192,000, bank charges, and late interest or rent. In [2023] SGHC 1, the developer's sale, a purchaser asked for extensions nine times after a completion date of 4 June 2020; several were granted, on condition that late completion interest was paid.

What the documents read do not settle

Some parts of completion day lie outside the texts read for this guide. The Conditions of Sale 2020 state who bears outgoings and tax but give no formula for the split, and they state an annual interest rate without a day count. The CPF Board's pages state the conditions for releasing savings, but not the moment in the day's sequence at which the money is released, nor how the Board's charge ranks beside a bank's mortgage. How a bank releases a housing loan at completion was not covered by any source read.

On disagreement, condition 16 says that before arbitration or court proceedings the parties shall consider mediation under the Law Society's mediation rules, and adds that this creates no legal obligation to attempt it.

The standard conditions put a date on every duty before completion and a rate on every day after it. What they leave open, the contract or the two sides must fill.
