When am I legally bound at a property auction?

At the fall of the auctioneer's hammer on the highest bid (at or above the reserve). There is no cooling-off period, so only bid if you are ready and financed.

What consent is needed for an en-bloc sale?

At least 80% by share value and by strata floor area where 10 years or more have passed since the latest Temporary Occupation Permit for the development (or the Certificate of Statutory Completion where no TOP was issued), or 90% where less than 10 years have passed — then Strata Titles Board approval, with the sale made in good faith.

Can an owner change their mind after signing a collective sale agreement?

Yes, but only briefly. An owner who signs the collective sale agreement may rescind that signature by serving written notice within 5 days after the day of signing, excluding Saturdays, Sundays and public holidays. The right can be used only once for the same agreement. Separately, the requisite 80% or 90% consent must be reached within 12 months of the date the first owner signed the agreement, or the process must begin again.

On what grounds can a minority owner object to an en-bloc sale?

A non-consenting owner has 21 days from service of the notice of the proposed application to file an objection with the Strata Titles Board. The Board must not approve the sale if the transaction was not in good faith — assessed on three statutory factors only: the sale price, the method of distributing the proceeds, and the relationship of the purchaser to any of the owners. Where a valid objection cannot be mediated, the Board issues a stop order and the application goes to the General Division of the High Court, which must refuse the sale if an objecting owner would incur a financial loss — the proceeds for their lot after allowed deductions are less than the price they paid for it, or cannot redeem the mortgage on the lot (Land Titles (Strata) Act s 84A(2A), (7)–(8)).

Selling a property before it is completed — typically on-selling an uncompleted unit bought from a developer. It can attract Seller's Stamp Duty if sold within the holding period.

Does a seller have to tell a buyer about defects in the property?

It depends on whether the defect is in the title or in the condition. Under caveat emptor the seller gives no warranty about the physical condition of a completed property and need not volunteer defects — the buyer is expected to inspect, and his solicitor to raise legal requisitions and searches, before the option is exercised. A latent defect in title is the opposite: the seller's duty is to show good title, so an undisclosed easement, restrictive covenant, encumbrance or adverse claim that the buyer could not discover must be disclosed, failing which the buyer may refuse to complete and rescind. Caveat emptor also protects silence only, never a false statement — actively concealing a defect, answering a buyer's question falsely, or giving a misleading half-truth can amount to misrepresentation despite an "as is, where is" clause. A salesperson is held to more than caveat emptor in any event: the Code of Ethics and Professional Client Care requires accurate information and forbids misrepresentation, and a misleading omission is an unfair practice under the CPFTA.

Paper 2 · Sale of Private Properties (New, Resale & En Bloc) · 19 min read

En Bloc, Auction & the Private Sale Process (Singapore)

Must-know for the exam

At auction the contract binds at the fall of the hammer with no cooling-off period; in a tender the seller is not bound if no bid meets the reserve.
The resale flow runs OTP (option fee commonly 1%), exercise within the option period (often 14 days), caveat, legal requisitions and searches, then completion typically 8 to 12 weeks later.
Under caveat emptor the seller warrants good title but not physical condition; a latent defect in title must be disclosed or the buyer may refuse to complete and rescind.
Caveat emptor protects silence, never a false statement: active concealment, a false answer or a half-truth is misrepresentation, and an "as is, where is" clause does not cure it.
Under the Conditions of Sale 2020 the seller bears outgoings and property tax to the scheduled completion date, and keeps the risk until completion or the buyer takes possession.
SSD is the seller's tax, due within 14 days of the contract; if the seller fails to pay, the buyer may, but need not, deduct it and pay, counting towards the price.
En-bloc consent (by share value and area): 90% under 10 years from latest TOP, 80% from 10; a Bill passed 8 Sep 2026 adds 70% (40–59) and 65% (60+) once it commences.
Consent must be reached within 12 months of the first CSA signature; a signatory may rescind once within 5 working days, and a rescinding signatory does not start the clock.
The CSC is elected before anyone signs, must launch by public tender or public auction, and may sell by private contract only within 10 weeks after the close.
Objections are due within 21 days; the STB refuses a sale not in good faith (price, distribution, buyer's links), and the High Court one causing an objector financial loss.

A private property can change hands several ways, and each has its own rules on when a binding contract forms and how the money flows. This page covers the methods of sale, the resale conveyancing timeline, new-launch sales, subsales and the collective (en-bloc) sale — the whole Sale of Private Properties topic in one place. (For the mechanics of the Option to Purchase itself, see the OTP page.)

Methods of sale

Method	When it binds / how it works
Private treaty	Ordinary negotiated sale via an Option to Purchase; the most common route.
Auction	A binding contract forms at the fall of the hammer; governed by the Conditions of Sale, subject to a confidential reserve price; a buyer's premium may apply.
Tender	Sealed bids by a deadline; the seller is NOT bound if no bid meets the reserve, and may negotiate with the best bidder.
Expression of Interest (EOI)	Used for high-value / prime assets to gauge serious interest before a structured sale.

The resale conveyancing flow

Option to Purchase (OTP) granted by the seller (vendor) on payment of the option fee (commonly 1%).
Exercise the OTP within the option period (often 14 days) by signing and paying the balance deposit — this forms the binding Sale & Purchase contract.
Caveat lodged by the buyer's lawyer to protect the buyer's interest on the title.

From the rest of this lesson

The trap

Two favourite errors. First, the cut-off for outgoings and property tax is the scheduled completion date, not the day completion actually happens. Second, SSD is never the buyer's tax. The buyer's right to deduct it is an option to protect himself, not a duty to pay.

Exam takeaway · remember this

Know the methods of sale (private treaty, auction — binding at the hammer, tender — seller not bound below reserve). Know the resale flow: OTP → exercise → caveat → requisitions → completion → apportionment. On a completed private sale start from caveat emptor: no duty to volunteer physical defects, but a latent defect in title must be disclosed, and no clause protects a misrepresentation. New launches run on the HDR S&P + progressive payments + defects liability. Subsales can trigger SSD. En-bloc: 80% consent where 10 years or more have passed since the latest TOP, 90% where less than 10 have — collected on a CSA within a 12-month permitted time, subject to each signatory's 5-day right to rescind, then an STB order for sale (objections within 21 days; unresolved ones go to the General Division of the High Court), refused if the sale was not in good faith or if an objector would suffer a financial loss.
