The word conveyancing sounds technical, but the role is simple to describe: your lawyer is the person who makes sure the property legally and safely changes hands, from the moment you exercise the OTP to the day you get the keys.
What the role actually covers
A conveyancing lawyer's work starts before you even exercise the OTP, reviewing the terms of the option and the draft Sale and Purchase Agreement to flag anything unusual. After exercise, they run a title search to confirm the seller's ownership and check for any existing charges, caveats, or encumbrances against the property. They raise legal requisitions with relevant authorities, coordinate with your bank so the mortgage is ready in time, liaise with CPF Board or HDB if you are using CPF or an HDB loan, prepare the transfer documents, and manage the actual exchange of funds and keys at completion.
Why private resale purchases need one
A private resale transaction has no government agency standing in as a default administrator, the buyer's lawyer is the one who lodges a caveat to protect your interest in the property once the OTP is exercised, and who ensures the seller's mortgage, if any, is properly discharged before you pay the balance. Without a lawyer acting for you, there is no one independently checking these steps on your behalf, which is why private resale purchases are not, in practice, done without one.
Why HDB resale is slightly different
For HDB resale flats, HDB itself runs much of the transaction infrastructure, the HFE letter, the resale portal, the valuation, and the actual completion appointment. Because of this, HDB offers its own conveyancing service as an alternative to engaging a private lawyer. Either party can choose HDB's service or a private law firm independently of what the other party chooses. The legal work of checking title and preparing the transfer still happens either way, just through a different provider.
When to engage one
Engage your lawyer as early as possible in the option period, ideally around the time you pay the option fee, not in the final days before the exercise deadline. This gives them time to review the OTP terms while you still have room to raise concerns or negotiate, rather than discovering an issue after you are already committed. Waiting until late in the option period is one of the most common ways buyers run out of runway to exercise on time.
What to check when choosing a lawyer
- Recent experience with the specific transaction type, HDB resale, private resale, or new launch, since the process and paperwork differ.
- A clear written quote covering what is included and what triggers an additional charge.
- Responsiveness, since delays in returning documents or answering the bank's queries can push your completion date back.
Frequently asked questions
Can HDB flat buyers skip using a lawyer completely?
HDB resale buyers can use HDB's own conveyancing service instead of a private lawyer, so in that sense the legal work is handled either way, just by different providers. Skipping legal representation entirely is not advisable for either HDB or private purchases.
What happens if I do not engage a lawyer for a private resale purchase?
In practice this is not workable, since a private resale purchase requires a lawyer to lodge the caveat, handle the transfer, liaise with your bank on the mortgage, and manage completion. Private property transactions in Singapore are not designed to be done without legal representation.
When should I engage my conveyancing lawyer?
As early as possible, ideally before or right when you pay the option fee, not after you exercise. Engaging early gives your lawyer time to review the OTP terms and flag issues while you still have room to negotiate.
