Sale and Purchase Agreement (S&P)

By Winfred Quek · CEA R073319H · Singapore property glossary

What is a Sale and Purchase Agreement (S&P)? The Sale and Purchase Agreement, or S&P, is the formal contract a developer issues after a buyer exercises the Option to Purchase on a new launch unit, setting out the price, the unit description and the payment schedule both sides are bound to. It replaces the short Option to Purchase document once the buyer commits to proceed.

Rates and thresholds change. The current figures are kept in one place: the Singapore property rules reference.

Once a buyer exercises the Option to Purchase on a new launch unit, the developer issues the S&P, a longer and more detailed contract that formalises the sale. For licensed developers, the core structure of this document is prescribed under the Housing Developers Rules, which is meant to give buyers a more standardised and protective process than a privately negotiated resale contract. It sets out the exact unit and floor area, the agreed price, the payment schedule tied to construction milestones, and the terms both parties must follow through to completion.

The S&P matters because it is the document that actually binds the transaction; the Option to Purchase is only the first step. Once signed, stamp duty becomes payable to IRAS, typically within 14 days, and the buyer's payment obligations follow the schedule set out in the agreement, not just the summary a sales team may have described verbally. Buyers should also confirm whether their purchase runs under the standard progressive payment structure or a different scheme, since this changes how cash and CPF are drawn down over the construction period.

A common misunderstanding is assuming the S&P can be negotiated the way a resale contract sometimes is. Because the main form is prescribed for licensed developers, there is generally less room to alter core terms, though schedules, specifications and any addenda can still differ meaningfully between projects and should be read in full rather than skimmed. Buyers also sometimes discover, only after signing, that the unit number, stack, or floor area schedule they thought they were buying does not match what was shown at the showflat.

Before signing, check that the unit number, floor area and stack match your booking, review the full payment schedule rather than a marketing summary, confirm the defects liability terms, and have a conveyancing lawyer review the agreement. Keep track of the 14 day stamp duty deadline once the agreement is dated, since late payment attracts penalties from IRAS.
