Conveyancing is the legal process of transferring ownership of a property from seller to buyer, and for most Singaporeans, buying or selling a home is one of the largest financial transactions they will ever make. Understanding roughly how the process works, even if a lawyer is handling the details, makes the whole experience considerably less stressful. This guide walks through how conveyancing works in Singapore, with a focus on HDB resale flats, since that is the path most Singaporean buyers and sellers will actually go through.
Before the Option to Purchase
Before a buyer can be granted an Option to Purchase for an HDB resale flat, they generally need a valid HDB Flat Eligibility letter, which confirms they meet the eligibility criteria and gives a sense of their loan options. On the seller’s side, the flat needs to have met its Minimum Occupation Period, and both parties are usually working with a property agent registered with the Council for Estate Agencies, whose registration can be checked on the CEA’s public register before signing anything.
The Option to Purchase
Once a buyer and seller agree on a price, the seller grants the buyer an Option to Purchase, commonly called the OTP, in exchange for an option fee, typically a modest amount agreed between the parties, capped by HDB rules alongside the later exercise fee. The OTP gives the buyer the exclusive right, but not the obligation, to proceed with the purchase within a fixed window, which for HDB resale flats is 21 calendar days. Both the option fee and the later exercise fee must be paid in cash rather than CPF, which is a detail that catches some first-time buyers by surprise.
During this option period, the buyer typically finalises their financing, whether that is converting an in-principle approval into a formal bank loan offer, or confirming an HDB loan based on their eligibility letter.
Exercising the Option
If the buyer decides to proceed, they exercise the OTP within the 21-day window by paying the exercise fee, which together with the earlier option fee usually adds up to a modest, capped total. At this point, a legally binding contract exists between buyer and seller. For buyers taking a bank loan, appointing a conveyancing lawyer at this stage is generally mandatory, while buyers using an HDB loan have the option of using HDB’s own legal service instead of a private lawyer.
Submitting the Resale Application
After the option is exercised, both buyer and seller submit their respective portions of the resale application through the HDB Resale Portal, and there is a window, typically about a week, for the second party to complete their portion after the first submits. Missing this window can cause the whole application to lapse, forcing both sides to restart, so this is a stage where prompt action genuinely matters.
HDB Processing and the Role of Your Lawyer
Once HDB accepts the application, a processing period follows, generally around eight weeks, though the full timeline from option to completion is commonly quoted as somewhere between eight and twelve weeks, sometimes longer depending on appointment availability. During this stretch, your conveyancing lawyer, or HDB’s legal team if you chose that route, handles the legal groundwork: reviewing title, preparing the necessary documents, coordinating with the bank if a loan is involved, and calculating the CPF refunds and figures that will apply at completion.
Stamp duties, both the Buyer’s Stamp Duty and, if applicable, Additional Buyer’s Stamp Duty, are payable within fourteen days of exercising the option, and your lawyer will typically help arrange for this to be paid, whether through CPF, cash, or a combination.
Costs Beyond the Purchase Price
Buyers should budget for more than just the flat’s price and the option fees. Buyer’s Stamp Duty applies to every property purchase in Singapore, calculated on a tiered basis against the purchase price or market value, whichever is higher. If this is not your first property, Additional Buyer’s Stamp Duty may also apply, at a considerably higher rate, so it is worth understanding your specific position, including citizenship and existing property ownership, before you commit to a purchase. Beyond stamp duty, expect conveyancing legal fees, a resale application fee payable to HDB, and, for bank loan buyers, valuation and legal fees associated with the loan itself. Sellers, meanwhile, should budget for their own conveyancing legal fees and the agent’s commission, if one was engaged, and should be aware that any CPF used toward the flat, along with accrued interest, is deducted from the sale proceeds before cash is released.
Common Causes of Delay
The most frequent causes of delay in an HDB resale transaction are incomplete or inconsistent documentation, disputes over the agreed valuation, financing that has not been fully arranged before the option is exercised, and simply the availability of appointment slots during a busy period. Buyers can reduce their own risk of delay by securing loan approval, whether bank or HDB, as early as possible, ideally before exercising the option, and by responding promptly to any request from HDB or their lawyer during the processing window, since a slow response on your end is one of the few delays genuinely within your control.
Completion
At completion, both parties, usually together with their lawyers, finalise the transaction. The buyer’s financing is disbursed, outstanding amounts are settled, and for the seller, any CPF principal and accrued interest used toward the flat is returned to their CPF Ordinary Account, which is a statutory requirement rather than optional. Keys are handed over, and ownership formally transfers at this point.
How Private Property Conveyancing Differs
Conveyancing for private resale property follows a broadly similar shape but with some differences. The option period is often shorter, commonly two to three weeks rather than 21 days, the deposit structure is usually a percentage of the purchase price rather than a small capped fee, and there is no HDB approval process to wait for, since the transaction is between private parties. This generally makes private resale conveyancing somewhat faster overall, though it still typically takes several weeks from option to completion once financing and legal work are factored in.
Why a Conveyancing Lawyer Matters Even When Not Strictly Required
Even where using a lawyer is optional, such as for HDB loan buyers who could use HDB’s legal service instead, many buyers and sellers still choose to engage their own conveyancing lawyer. A lawyer acting solely for you, rather than facilitating the transaction more generally, can flag issues specific to your interests, handle the transfer of funds securely, and be your direct point of contact if something unusual comes up during the process.
Frequently Asked Questions
Can I back out of a transaction after exercising the Option to Purchase?
Once the option is exercised, a binding contract exists, so withdrawing at that point generally has financial consequences, such as forfeiting the option money, so this decision should be treated as final rather than something to reconsider casually afterward.
What happens if my HDB resale application is rejected after I have already exercised the option?
This can happen for reasons such as eligibility issues that only surface during processing, and the specific consequences depend on the reason for rejection, so it is important to raise this immediately with your lawyer or agent rather than assuming the transaction will simply proceed regardless.
Do I need a separate lawyer from the seller, or can one lawyer handle both sides?
In Singapore, a single law firm generally cannot act for both the buyer and the seller in the same transaction due to the conflict of interest involved, so each party appoints their own conveyancing lawyer.
How much do conveyancing legal fees typically cost for an HDB resale flat?
Fees vary by firm and by the complexity of the transaction, including factors like the loan amount and number of owners involved, so it is worth asking for a clear fixed-fee quote from your lawyer early in the process rather than assuming a standard figure applies to every transaction.
Is it possible to buy a property in Singapore without ever meeting the seller in person?
Yes, this is common, since much of the process is handled through agents, lawyers, and the relevant online portals, with parties typically only meeting, if at all, briefly at the completion appointment.
