Provisional Sale and Purchase Agreement Hong Kong: Risks, Deposits, and What Happens If You Back Out

The Provisional Sale and Purchase Agreement (PSPA) is the moment a Hong Kong property transaction becomes legally binding. Not when you sign the formal agreement. Not when you get your mortgage approved. The PSPA — a document your agent drafts, sometimes within hours of you shaking hands on a price — locks you into the deal with immediate legal effect and real financial consequences if you walk away.

Many first-time buyers in Hong Kong treat the PSPA as a preliminary step that can be reversed if their financing falls through or they change their mind. It cannot. Understanding what the PSPA commits you to, and what your exposure is if something goes wrong, is one of the most important things to get right before you buy.

What the PSPA Is

The Provisional Sale and Purchase Agreement is a legally binding contract executed between the buyer, seller, and estate agent (as a witness or signatory depending on circumstances). It specifies:

• The names of both parties
• The property address and description
• The agreed purchase price
• The amount of the preliminary deposit
• The date for signing the Formal Sale and Purchase Agreement (typically 14 days later)
• The scheduled completion date

The agent drafts the PSPA based on the negotiated terms. Both buyer and seller sign it — usually in the agent's office, sometimes simultaneously, sometimes separately — and the buyer pays the preliminary deposit immediately.

The Preliminary Deposit: How Much, to Whom

The preliminary deposit — colloquially called "細訂" (small deposit) in Cantonese — is typically 3% to 5% of the purchase price. On a HK$6,000,000 flat, that's HK$180,000–HK$300,000 paid at the moment of signing the PSPA.

Under normal circumstances, this deposit goes directly to the vendor or is held in the agent's stakeholder account. If the property is in negative equity — meaning the seller's outstanding mortgage balance exceeds the transaction price — the deposit must be held by the vendor's solicitor as a stakeholder to protect the buyer against insolvency risk.

At the Formal Sale and Purchase Agreement stage (typically 14 days after the PSPA), the buyer pays a further deposit bringing the total to 10% of the purchase price. This second tranche is the "大訂" (big deposit).

No Cooling-Off Period in the Secondary Market

This is the critical legal distinction that many buyers miss.

First-hand (new development) purchases are governed by the Residential Properties (First-hand Sales) Ordinance. After signing the Preliminary Agreement for Sale and Purchase (PASP) on a new property, buyers have a 5-working-day statutory cooling-off period. If they elect not to proceed to the formal Agreement for Sale and Purchase (ASP) within that window, the preliminary deposit (5%) is forfeited — but the developer has no further legal claim.

Secondary market (resale) purchases have no statutory cooling-off period whatsoever. Signing the PSPA is immediately and irrevocably binding. The 14-day window between PSPA and Formal S&P is not a grace period — it's the preparation time for both solicitors to draft and review the formal agreement.

What Happens If the Buyer Backs Out

If a buyer fails to proceed to the Formal S&P or fails to complete:

1. Preliminary deposit forfeited: The vendor keeps the full initial deposit (3–5% of purchase price).
2. Agency commissions owed: The buyer must pay both the buyer's 1% agent commission and the seller's 1% agent commission — totalling 2% of the purchase price. On a HK$6,000,000 flat that's HK$120,000 in additional commission liability.
3. Potential litigation: The vendor may sue for specific performance (forcing the buyer to complete) or for the difference between the contracted price and any lower price achieved in a subsequent resale.

The combined financial exposure on a HK$6,000,000 transaction — deposit plus both commissions — can approach HK$420,000–HK$480,000, representing a catastrophic loss for a buyer who signed without confirmed mortgage approval.

What Happens If the Vendor Defaults

If the vendor fails to proceed:

1. Deposit returned: The vendor must refund the full preliminary deposit.
2. Liquidated damages: The vendor must pay the buyer an additional sum equal to the deposit (i.e., they pay back the deposit and then pay the same amount again).
3. Agency commissions owed: The vendor remains liable for both sides' agent commission.
4. The buyer cannot force completion. In practice, specific performance against a vendor is difficult to enforce when the vendor lacks the means to perform or has sold to another party.

The Mortgage Shortfall Risk

The most common reason buyers need to walk away from a PSPA is mortgage failure — either the bank's valuation comes in below the purchase price, or the AIP-stage income assessment doesn't hold up under formal underwriting.

Scenario: You agree to buy a flat for HK$6,200,000. Your AIP suggested you could borrow HK$4,650,000 (75% LTV). After signing the PSPA and paying HK$248,000 (4%), the bank's formal valuation puts the property at HK$5,800,000, and they'll only lend 70% of that — HK$4,060,000. You're now short HK$590,000 on your financing plan. If you can't bridge that gap, you're walking away from your deposit and paying both commissions.

This scenario happens. The fix is to secure full mortgage pre-approval — including a bank inspection and valuation confirmation — for the specific property before you sign the PSPA. Not all banks will do this pre-signing, but you should at minimum have a firm AIP based on the specific property details and confirmed the bank's willingness to lend at your agreed price before the ink dries on the PSPA.

Reviewing the PSPA Before Signing

Your conveyancing solicitor should review the PSPA before you sign it. Standard PSPA forms exist in the market, but terms can vary, and seller's agents sometimes insert clauses that are not in your interest. Key points to verify:

• Completion date is realistic given your mortgage timeline
• Preliminary deposit payment mechanics are clearly specified
• Negative equity stakeholder requirements (if applicable) are correctly stated
• No unusual restrictions on the property are buried in the agreement
• The description of the property (unit, floor, estate, address) is exact and correct

The typical PSPA is short — one or two pages — but the legal exposure is disproportionately large. Fifteen minutes with a solicitor before signing costs far less than what you'd lose if the deal falls apart.

The PSPA in the Context of the Full Purchase Timeline

Signing the PSPA is Step 3 in a 6-step purchase process:

1. Secure Approval in Principle (AIP) from bank
2. Conduct property search; instruct estate agent
3. Sign PSPA, pay 3–5% preliminary deposit
4. Sign Formal S&P at solicitors' offices (14 days post-PSPA), pay to 10% total
5. Mortgage finalized; title review; completion day — pay balance + stamp duty
6. Land Registry registration within 1 month

The PSPA is not the end of due diligence — your solicitor continues reviewing the title deeds and the Deed of Mutual Covenant through to completion. But it is the point where your financial commitment becomes legally locked.
