The five hard legal deadlines — and the cost of missing each
Most Singapore property guides walk you through the steps. This page takes a different angle: the deadlines. Every legal stage in a property transaction has a fixed date attached, and missing one usually costs money rather than time. Here is the deadline table I give every buyer at the start of a purchase.
| # | Deadline | When it falls due | Cost of missing it |
|---|---|---|---|
| 1 | Option exercise | Within 14 days (private resale) or 21 days (HDB resale) of grant | Option lapses — seller may resell, option fee is at risk |
| 2 | Stamp duty payment | Within 14 days of execution (30 days if executed overseas) | Late-payment penalties imposed by IRAS |
| 3 | Completion | Typically 10–12 weeks from exercise (private); about 8 weeks after HDB accepts the resale application | Interest on outstanding sum and possible legal action for specific performance |
| 4 | Defects notification (new launches) | Within the defects liability period, typically 12 months from vacant possession | Developer liability can lapse — repairs become your cost |
| 5 | Seller's Stamp Duty window | Three-year holding period from purchase | SSD payable as a percentage of the sale price |
If you have already read the step-by-step conveyancing sequence, this deadline view is the one to save. If you want the stage-by-stage walkthrough, start with the summary table further down this page.
What is the Singapore property legal process?
The legal process is the sequence of binding steps that transfers ownership of a Singapore property from seller to buyer. It begins when a price is agreed and an Option to Purchase (OTP) is issued, moves through exercise and conveyancing, and ends at completion, when the balance of the purchase price is paid and the title is registered.
Buyers often prepare intensely for the price negotiation and barely at all for the legal sequence. That is a mistake, because the legal stage contains fixed deadlines, non-refundable payments and one irreversible decision: exercising the option.
Stage 1 — The Option to Purchase
An OTP is a contract granting you the exclusive right, but not the obligation, to buy the property within a stated exercise period, in exchange for an option fee.
| Element | HDB resale (typical) | Private resale (typical) |
|---|---|---|
| Option fee | Usually SGD 1,000 or a small fixed sum | Typically 1% of the price |
| Exercise period | Usually 21 calendar days | Usually 14 calendar days |
| Option exercise fee | Balance of the deposit on exercise | Usually 4% more (5% deposit in total) |
During the option period you should be completing due diligence: confirming financing, checking the HDB Flat Eligibility (HFE) letter where applicable, reviewing the title, and commissioning a valuation if your bank requires one.
Illustrative example — private resale at SGD 2,000,000
Option fee on grant: about SGD 20,000 (1%).
Option exercise fee on exercise: about SGD 80,000 (taking the deposit to 5%, i.e. SGD 100,000).
Remaining 95%: settled at completion, funded by your loan and CPF as applicable.
Illustrative only — not a quote or a valuation.
Stage 2 — Exercising the option
Exercising the option means signing the acceptance and paying the exercise fee within the option period. At that moment you become legally bound to complete the purchase.
What must be ready before you exercise
- Loan approval or a firm in-principle offer, with the loan amount confirmed.
- Cash and CPF component confirmed, including the downpayment and the buyer's stamp duty.
- HFE letter for HDB purchases, where required.
- Conveyancing lawyer appointed — the conveyancing file should be opened before exercise, not after.
Buyer's and Additional Buyer's Stamp Duty
Buyer's Stamp Duty (BSD) applies on every purchase and is payable within 14 days of execution (or within 30 days if executed overseas). Additional Buyer's Stamp Duty (ABSD) applies on top for applicable buyer profiles and second properties. Stamp duty is a legal obligation, not a negotiation point.

Stage 3 — Conveyancing and caveats
Conveyancing is the legal work that transfers title. Your lawyer (or the HDB conveyancing process for HDB flats) will:
- Conduct title searches with the Singapore Land Authority (SLA).
- Raise and answer legal requisitions with the seller's solicitor.
- Prepare the transfer documents and the mortgage documents with your lender.
- Lodge a caveat registering your interest in the property.
- Compute and account for the apportionment of property tax and, for private property, management charges.
What is a caveat?
A caveat is a notice lodged with SLA that registers an interest in a property — the buyer's interest, and separately the lender's. It protects that interest against subsequent claims until the transfer is registered. On completion, the caveat is removed and the title is registered in your name.

Stage 4 — Completion and keys
Completion is the settlement date. The buyer's lawyer pays the balance of the purchase price to the seller's lawyer, the transfer is registered, and vacant possession is handed over.
| Milestone | Typical timing |
|---|---|
| Option granted | Day 0 |
| Option exercised | Within 14 days (private) / 21 days (HDB resale) |
| Completion — private resale | Typically 10–12 weeks from exercise |
| Completion — HDB resale | Generally about 8 weeks after HDB accepts the resale application |
| Defects liability period | Typically 12 months for new launches, from vacant possession |
After completion
- Update your address with ICA and relevant agencies.
- Set up GIRO for property tax and, for private property, management fees.
- For new launches, document any defects with dated photographs on handover day.
Legal fees — what to budget
| Item | Typical range (SGD) | Note |
|---|---|---|
| Conveyancing — HDB resale | Approx. 1,500 – 2,500 | Includes CPF and HDB documentation |
| Conveyancing — private resale | Approx. 2,500 – 4,000 | Excludes disbursements |
| Disbursements | Approx. 500 – 1,200 | Searches, caveat lodgement, registration fees |
| Mortgage stamp duty on loan | Up to 0.4% of the loan | Where applicable; check current rules with IRAS |
| Buyer's Stamp Duty | Scales with price | Payable within 14 days of execution |
Ranges are typical industry figures for planning, not quotes. Confirm with your appointed lawyer.
Common mistakes
- Exercising the option before financing is confirmed. An option fee is not a loan approval.
- Letting the option period lapse while still negotiating — the seller is then free to sell to someone else.
- Missing the stamp duty deadline. Stamp duty is due within 14 days of execution and late payment carries penalties.
- Appointing a lawyer after exercise. Open the conveyancing file before you sign, so title issues surface during your option window.
- Forgetting apportionments. Property tax and management charges are split at completion; budget for the adjustment.
- Assuming ABSD refunds are automatic. Where relevant, the conditions are strict and depend on your profile and transaction order.
Practical advice from Flora He
Treat the legal process as a project with five fixed dates: option grant, option exercise, stamp duty payment, completion, and (for new launches) the defects notification deadline. Write them down the day you start negotiating. Nine out of ten problems I see at this stage are timing problems, not legal problems — and timing problems are preventable.
If you are upgrading rather than buying your first home, sequence the legal steps against your MOP and Seller's Stamp Duty windows first. Read more in the articles hub: Flora He — Articles.
Frequently Asked Questions
What is the Option to Purchase in Singapore?
The Option to Purchase (OTP) is a legal agreement granting the buyer the exclusive right to buy the property within a stated exercise period, usually 14 days for resale private property and 21 days for HDB resale, in exchange for an option fee.
How long is the property completion period in Singapore?
For private resale property, completion is typically 10 to 12 weeks from the date the OTP is exercised. For HDB resale flats, completion is generally about 8 weeks after HDB accepts the resale application.
How much are conveyancing and legal fees in Singapore?
Legal fees for a typical Singapore residential transaction commonly range from about SGD 2,500 to SGD 4,000 for private property, with lower fees for HDB flats. Disbursements are additional, and fees are usually paid partly on exercise and partly on completion.
Can I back out after exercising the Option to Purchase?
No. Once you exercise the OTP you are legally bound to complete. Withdrawing after exercise can forfeit your deposit and expose you to a legal claim for damages.
What is a caveat in Singapore property?
A caveat is a notice lodged with the Singapore Land Authority registering the buyer's or lender's interest in a property, protecting that interest against later claims until completion and registration.
