Delayed Handover in Real Estate: Buyer Checklist

Buying off-plan housing means paying today for an asset you will receive in the future — and the single biggest risk is the developer failing to hand over on time. The Law on Real Estate Business No. 29/2023/QH15 (effective from 1 August 2024) has significantly strengthened the layers of protection available to buyers. The problem is that many buyers do not know what tools they have, or use them in the wrong order.

The checklist below arranges the response steps from softest to strongest. For the broader context, see our real estate, construction and projects coverage.

1. Step 1: Re-read the contract — pin down the developer's exact obligations

[ ] What handover date does the contract record? Is there an extension clause for force majeure; which events count as force majeure (pandemics, policy changes, natural disasters) and what notification procedure applies.
[ ] Penalty for late handover: the penalty level (usually a percentage of the contract value or a per-day-of-delay rate), how it is calculated, and any cap.
[ ] Unilateral termination conditions: how long a delay entitles the buyer to terminate; the notice procedure; the refund consequences (with or without interest, and the refund deadline).
[ ] Damages clause: the scope of recoverable loss (rental costs, bank loan interest and the like) and the burden of proof.
[ ] Dispute resolution mechanism: how long must negotiation run before suit can be filed; arbitration or court.

2. Step 2: Check the statutory layers of protection

Even where the contract is thinly drafted, the law still gives buyers the following rights:

[ ] Right to demand timely handover and compensation (Article 20, Law on Real Estate Business 2023): buyers and hire-purchasers of housing and construction works may require the seller to hand over on time, in the agreed quality and on the other agreed conditions; and may claim damages for loss caused by the seller's fault.
[ ] The seller's corresponding duties (Article 19): the seller or lessor must hand over on time, in the agreed quality and on the agreed conditions; and must compensate loss caused by its own fault.
[ ] Bank guarantee (Article 26): check whether, at signing, the developer provided a guarantee letter from a commercial bank covering its financial obligations. Under the rules, a developer of an off-plan housing project must be guaranteed by a bank before selling or hire-purchasing; where the housing is not handed over as committed and the buyer so requests, the guaranteeing bank must refund the advance payments and other amounts to the buyer under the guarantee contract. Key warning: buyers may choose in writing whether or not to have the guarantee when signing — if you signed a written waiver, this layer of protection is gone.
[ ] Is the payment schedule lawful (Article 25): payment for off-plan housing is made in instalments — the first instalment may not exceed 30% of the contract value; later instalments must track construction progress, and the total may not exceed 70% of the contract value before handover (no more than 50% where the seller is a foreign-invested economic organisation); where no certificate of land use rights and ownership of land-attached assets has been issued, no more than 95% of the contract value may be collected. If the developer has collected beyond these thresholds, that is a powerful point in dealing with the developer and in reports to the regulators.
[ ] Is project information fully disclosed (Article 6): the developer must disclose project information fully, truthfully and accurately, including any restrictions on ownership or use rights and any mortgage status.

3. Step 3: Quantify the loss and the penalty

[ ] Draw up a schedule of actual loss: rent paid while waiting for handover, interest on the housing loan, opportunity costs, travel and meeting costs with the developer. Keep all invoices and receipts.
[ ] Compute the contractual penalty: apply the penalty formula in the contract to the actual number of days of delay.
[ ] Interest for late performance of a payment obligation: where a sum must be refunded and the obligor is late, the Civil Code (Article 357 read with Article 468) provides interest for late payment — 10% per year where the parties have not agreed otherwise. This rate applies only where there is no other agreement.
[ ] Distinguish penalties from damages: penalties apply where the contract provides for them; damages require proof of actual loss and causation. Both may be claimed together where the grounds exist.

4. Step 4: Deal directly with the developer

[ ] Send a formal written demand: state the contractual handover date, the days already delayed, and demand handover plus payment of the penalty and damages. Send it in a form with proof of receipt (post, authenticated email).
[ ] Require the developer to explain: the cause of the delay, actual progress, and a written commitment to a new handover date.
[ ] Negotiate a contract addendum: if you agree to grant more time, the addendum must record the new deadline, the penalty for a further delay, and your right to terminate unilaterally if the breach continues. Never accept oral promises.
[ ] Act collectively (where many buyers are affected): appoint representatives and agree on common demands — collective pressure is usually more effective than going alone, but every agreement must still be recorded in writing for each individual contract.

5. Step 5: Complaints, denunciations, feedback and petitions

Where direct dealing fails, distinguish three tools that differ in parties, procedure and receiving authority:

[ ] Complaint (under the Law on Complaints): a complaint against an administrative decision or administrative act of an agency or competent person that you consider to infringe your lawful rights and interests. Example: complaining about a decision or act of the housing management authority relating to confirmation of the project's eligibility to sell off-plan housing. File it with the very agency or person that issued the decision or committed the act, or with the person competent to resolve the complaint under the law.
[ ] Denunciation (under the Law on Denunciations): reporting the developer's legal violations to a competent agency, organisation or individual — for example, selling off-plan housing without meeting the conditions, raising capital in breach of the rules, or failing to disclose information under Article 6 of the Law on Real Estate Business 2023. A denunciation is not a complaint: it reports a legal violation (the denouncer need not be the directly harmed person), while a complaint asks for review of an administrative decision or act that infringes your own rights and interests.
[ ] Feedback and petitions: send feedback and petitions to the competent state management authority (Department of Construction, provincial housing management authority) about the project's delayed handover for inspection and handling within their authority — even before you have grounds for a formal complaint or denunciation. Administrative sanctions for violations in the real estate business sector are provided in Decree No. 339/2026/ND-CP — the specific conducts and fine levels must be checked against the text in force at the time of handling.
[ ] Check the project's mortgage status: under Article 183 of the Law on Housing 2023, a developer that has mortgaged the project must release the mortgage before signing contracts with customers (except where the law provides otherwise), and the release must appear in the written notice confirming eligibility to sell. If you discover the project is mortgaged and not released, that is a very strong point in feedback and petitions to the housing management authority.

6. Step 6: Litigation or arbitration

[ ] Identify the forum: per the dispute resolution clause in the contract — court or commercial arbitration.
[ ] Prepare the case file: the sale contract and addenda, payment receipts, correspondence with the developer, evidence of loss, the bank guarantee letter (if any).
[ ] Claims to plead: specific performance of handover + penalty + damages; or contract termination + refund + penalty + damages; provisional urgent measures (seizure of assets, account freezing) may be requested where the developer may dissipate assets.
[ ] Mind the limitation period: the limitation period for asking the court to resolve a contract dispute is 3 years from the date the claimant knew or should have known that their lawful rights and interests were infringed (Article 429, Civil Code 2015) — this is the substantive limitation period. Distinguish it from the limitation rules in the Civil Procedure Code, which govern litigation procedure. Track both so neither expires. See also our experience with deposit contract disputes in land and housing sales — many delayed-handover disputes originate at the deposit stage.

7. Frequently asked questions

How late must the handover be before a buyer can unilaterally terminate the contract?

The law does not set a single general deadline; the right to unilateral termination depends on the terms agreed in the sale contract. The first thing to do when handover is delayed is therefore to re-read the contract clauses on the handover deadline, breach penalties and termination conditions. Even where the contract is silent, buyers still have other tools: claims for damages, complaints and lawsuits under the Law on Real Estate Business 2023.

How are buyers of off-plan housing protected when the developer delays handover?

The Law on Real Estate Business 2023 protects buyers through several layers: the seller's duty to hand over on time (Article 19), the buyer's right to demand timely handover and compensation (Article 20), caps on pre-handover payments (Article 25), and the bank-guarantee mechanism for off-plan housing (Article 26). Buyers should check whether they have used all of these layers.

How does the bank guarantee help buyers when a project is delayed?

Under Article 26 of the Law on Real Estate Business 2023, a developer selling off-plan housing must have its financial obligations guaranteed by a bank before selling. If the developer fails to hand over the housing as committed and the buyer so requests, the guaranteeing bank must refund the advance payments and other amounts to the buyer under the guarantee contract. Note: buyers may choose in writing not to require the guarantee — that decision deserves careful thought.

Can a buyer claim both the contractual penalty and damages at the same time?

Yes, where the contract provides for a penalty and actual loss from the delay has arisen (for example, rental costs during the waiting period). The penalty is as agreed in the contract; damages must be proven, including the loss and its causal link to the delay.

Can a developer be administratively sanctioned for delayed handover?

Possibly, depending on the specific conduct — for example, raising capital or selling off-plan housing without meeting the statutory conditions, or failing to disclose project information fully. The sanctioned conducts and fine levels are set out in Decree No. 339/2026/ND-CP on administrative sanctions in the construction and real estate business sectors; the text in force at the time of handling should be consulted.

8. When to bring in a lawyer

Bring in a lawyer as soon as:

The amount already paid is large (usually from 30% of the contract value) and the developer is more than 3–6 months late.
The developer shows signs of financial distress: prolonged construction stoppages, changes of legal entity, seized assets.
You signed a written waiver of the bank guarantee without understanding all its consequences.
Many buyers are affected and the collective claim needs to be organised professionally.
The case involves the termination of investment projects or the developer has complex charter capital and investment capital.
