An unstamped agreement: void, or just unusable in court?
An unstamped sale and purchase agreement is not void between the buyer and seller. The real consequence is narrower and still serious: the document cannot be relied on as evidence in court, and cannot be used to register a dealing, until it is stamped and any penalty is paid.

What the statute fixes and what it leaves open
This post works through a distinction people get backwards, and the penalty that grows while they do The moment a deal becomes binding is rarely the moment people think it is, and the money paid before that moment is the money most often argued over.
The distinction people get backwards
The instinct many buyers and sellers have is that an unstamped agreement must be void — that without the stamp, there is no valid contract at all. That is not how it works. The agreement between the parties is formed the moment offer, acceptance and consideration exist; stamping is a separate legal requirement layered on top, and failing to meet it does not unwind the contract itself. What it does is restrict what you can do with the document afterwards. Getting this the right way round changes how urgently you treat a lapse — it is a defect to fix, not proof the deal never happened.
Inadmissible in evidence, not void
The practical bite of an unstamped agreement is that it cannot be received in evidence in court until it has been stamped. If a dispute arises — over the price, over a breach, over who owes what — and your agreement has not been stamped, you cannot simply hand it to a judge and rely on its terms. That is a real problem in litigation, because the agreement is usually the central document proving what was promised. But it is a problem about using the document, not a statement that the underlying bargain never existed.
You cannot register a dealing on it either
The second practical consequence sits at the land registry rather than in court. An instrument used to register a transfer, charge or other dealing needs to be stamped before the registry will act on it. So even outside a dispute, an unstamped agreement blocks you from progressing the paperwork that actually moves title or registers your interest — which matters even when both sides are on good terms and there is no argument to have in court at all.
The penalty accrues while it sits unstamped
Failing to stamp a document within the required time does not just leave you exposed on evidence and registration — a penalty accrues on the unpaid duty the longer the position continues. Because the specific penalty scale and the stamping deadline are not settled figures to quote in the abstract, the practical point is simpler: this is not a problem that improves by waiting. The exposure grows the longer an agreement sits unstamped, and the fix — get it assessed and stamped, and settle whatever penalty has accrued — is the same whether you act now or later, just cheaper now.
What to actually do about it
If you discover an agreement was never stamped, or was under-stamped, the sequence is to get it properly assessed and stamped, pay the duty and any accrued penalty, and only then treat it as usable in the ways described above. Do not treat an unstamped agreement as something to quietly keep using as-is — you may find, exactly when you need it most, in a dispute or at the point of registering a dealing, that it cannot do the job until this is fixed.
Check this against your own case
Read your own agreement rather than a summary of it. For an HDA residential unit the terms are prescribed by statute and cannot be watered down, so any clause that looks worse than the statutory position is worth querying immediately. For anything outside the HDA, the contract is whatever was drafted — and that is exactly where the risk sits.
Buyer checklist
People often get this backwards: an unstamped agreement is not void. Malaysian law treats stamping as a condition of using a document, not a condition of its existence — the contract between the parties still stands. What an unstamped agreement cannot do is go into evidence in court, and it cannot be used to register a transfer, charge or other dealing at the land registry, until it is stamped and the accrued penalty is settled. That distinction between "invalid" and "inadmissible until stamped" is the whole point.

Common questions
Is an unstamped sale and purchase agreement void?
No. The contract between the parties still stands; the consequence of not stamping is narrower — the document cannot be used as evidence in court or to register a dealing until it is stamped.
Can I still sue on an unstamped agreement?
You can bring the claim, but the agreement itself cannot be received in evidence until it has been stamped, which is a real practical obstacle if the agreement is your key document.
Can I register a transfer using an unstamped agreement?
No. An instrument used to register a transfer, charge or other dealing must be stamped before the registry will act on it.
Does the problem get worse the longer I leave it unstamped?
Yes. A penalty accrues on unpaid duty the longer a document sits unstamped, so there is no advantage to waiting.
What should I do if I find an old agreement was never stamped?
Get it assessed and stamped, and settle the duty and any accrued penalty, before you rely on it in court or use it to register anything.

The Rebate Trick That Could Get Your Loan Flagged As Fraud
Developer packages that inflate the SPA price and rebate the difference to cover your downpayment can breach BNM lending rules and trigger LHDN stamp duty audits.
Lewis Conclusion
I always ask developers for the nett price in writing and confirm the bank is financing against that number, not the gross figure on the SPA cover page.
Sinking Fund Guide: What High-Rise Buyers Must Inspect
Strata high-rises require a sinking fund for major repairs under the Strata Management Act 2013. A chronically underfunded reserve will lead to large special levies.
Lewis Conclusion
I've seen too many buyers look only at the gym and pool, ignoring the sinking fund. Under the Strata Management Act, this fund is mandatory. For subsale, I check the AGM minutes to see if owners are default-happy — a 30% default rate on maintenance fees means the building is slowly dying. For new launches, if the developer offers a suspiciously low RM0.25/sqft fee, expect a rude 40% jump within two years of JMB takeover.

Understand LHDN's 2026 Stamp Duty Self-Assessment System (SAS), 30-day payment rule, 3-year audit window, and 100% first-buyer exemption up to RM500k.
Lewis Conclusion
Under SAS, speed increases but so does risk. Previously, LHDN gave you the final number. Now, you calculate, pay, and they can audit you later. First-time buyers under Budget 2026 get a full exemption up to RM500k until end of 2027. However, if you are buying with a hidden rebate side-letter that inflates the SPA, LHDN can audit that valuation. I advise all buyers to keep clean transaction records and avoid side agreements that can trigger a tax penalty 3 years down the line.
