When A “Common” Property Strategy Becomes A $180K Problem
February 8, 2026
What sort of advice do you expect a realtor to give, when it comes to your property transaction?
Sometime back, I wrote about the 99-1 arrangement and how it relates to property ownership and the legal issues surrounding it. Just last month, a case related to this issue came to an end when a buyer dropped their lawsuit against ERA Realty, the agent in question, and a conveyancing law firm.
In brief, the buyer had used a 99-1 ownership structure when purchasing a new launch unit at Normanton Park, with his father taking a one per cent share of the property. It was reported that the arrangement was meant to reduce the Additional Buyer’s Stamp Duty (ABSD) payable.
In a typical 99-1 arrangement, the ABSD would apply only to the 1% share held by the ABSD-liable party, rather than to the full property value.
In December 2024, however, IRAS disregarded the structure and imposed $180,945 in additional stamp duty and penalties. The buyer then sued the agent, agency and law firm, alleging that the 99-1 arrangement that was presented to them as a common and accepted method.
The defendants, in turn, denied giving tax or legal advice and argued that their roles did not extend to guaranteeing the legality of the arrangement.
This case garnered a lot of attention, but before it could be tested in court, the buyer discontinued the lawsuit (with each party bearing its own costs)
I do feel for the buyer here.
From personal experience, I saw on the ground that the 99-1 arrangement was widely known. It was discussed online, surfaced regularly in public Q&A forums, and was treated as normal as a discussion on sell-one-buy-two tactics. It was a part of the property buying discourse.
For almost a decade, this went on with no high-profile public enforcement to shut it down. It was only in recent years that scrutiny tightened and some uncertainty began to set in among those who’d used the structure.
A lot of this, I feel, comes down to what kind of agents should give, and what kind of advice we should be taking from them.
Far be it from me to blame agents for all of this or their clients. My point is that more often than not, buyers and sellers are seldom experts (barring a few seasoned investors) to the nuances of financing, tax laws, and transaction processes. Prevailing market knowledge tends to blur into one face: that of their realtor.
The expectation is that the agents should know everything. From how to get a different valuation (a mortgage broker’s job), to how the CPF rules work (something they should be calling CPF about), to, yes, the consequences of arrangements like 99-1 holding structures.
There’s a tendency for agents to appear to look inexperienced, or sometimes even incompetent (depending on how judgmental a client might get) if they don’t at least appear familiar with all this.
And that’s not really the fault of the client either, since most buyers and sellers go through only a handful of property transactions in their entire lives. Most are highly dependent on the licensed professionals who guide them, amid a sea of migraine-inducing jargon and acronyms.
CEA does have requirements that property agents act in their clients’ best interests.
But this could place a disproportionately high burden on agents. Providing the best advice on tax questions, financing rules, and regulatory interpretations is a big challenge since these are entire professional domains in their own right. There’s a big difference between knowing about stack facings and buyer profiles in Bedok vs. Jurong, versus knowing how IRAS might interpret a complex ownership structure.

These obligations set out by CEA also seem to be grounded in the principles. They define what agents should aim to do with their advice, but they’re less explicit about how the advice should be framed, where its boundaries lie, or how those boundaries are relayed to clients.
Now I’m not saying agents should be completely barred from giving this sort of tangential advice.
I know that’s unrealistic, given how much overlap there is between these topics. What may be workable is a requirement for agents to clearly flag when a discussion strays beyond their core role. Agents can still explain how bank valuations or a 99-1 arrangement is commonly interpreted, but they should also put it in writing that this is not their main field.
Saying “your lawyer is the one who should be doing this, take their word over mine” doesn’t weaken the agent’s role but strengthens it.
Requiring this to be explicit and written down also protects agents in turn. It helps prevent conversational opinions from being mistaken as professional advice or actual endorsement. And if something ever does go wrong, it will be much clearer where the bad or negligent advice came from.
There really isn’t much incremental cost to doing this, and it may help to prevent these sorts of messy lawsuits in future.

Do we know if there was a settlement? I’m guessing realtors and real estate lawyers don’t want this to hit the court.
Because if the plaintiff is victorious, a lot of lawsuits will follow, and the realtors / real estate lawyers will have to pay out a lot of money.
