Commentary on Precedent No. 09/2016/AL: Unnotarized Residential Sale Contracts

Background

Precedent No. 09/2016/AL was adopted by the Council of Judges of the Supreme People's Court (SPC) on 17 October 2016 and published under Decision No. 698/QĐ-CA. It is among the first contract-law precedents in Vietnam, establishing an important principle: an unnotarized residential sale contract may still be recognised as valid where the buyer has performed at least two-thirds of their contractual obligations.

This precedent reflects Vietnamese courts' growing willingness to look at transactional substance — an important step in balancing the formal requirements of the Civil Code against protecting the legitimate interests of a party that has fully performed.

Facts of the case

The plaintiff, Mrs H, and the defendant, Mr T, entered into a residential sale contract in 2009. Under that contract:

  • The price was VND 1.2 billion
  • Mrs H paid the full purchase price
  • Mr T delivered the property and Mrs H has used it continuously since 2009
  • However, the contract was never notarized as required by the Housing Law 2005

In 2014, Mr T sued to have the contract declared void for non-compliance with the formal requirement, and to recover the property. Mrs H counterclaimed for recognition of the contract's validity.

Reasoning of the Council of Judges

The Council advanced three key strands of reasoning:

1. Application of Article 134 of the Civil Code 2005

Article 134 of the Civil Code 2005 (now Article 129 of the Civil Code 2015) provides: "Where the law requires a specific form for a civil transaction as a condition of its validity but the parties fail to comply, the court or other competent state body shall, at the request of one or all parties, order the parties to comply with the formal requirement within a stated period; failing which the transaction shall be void."

2. The principle of substantive performance

The Council found that the buyer's full payment and acceptance of delivery sufficiently demonstrated the parties' intent. The lack of notarization was a formal defect that did not go to the substance of the agreement.

Where a party has performed at least two-thirds of the obligations in a transaction, the court may, at the request of one or all parties, recognise the validity of that transaction.

3. Protection of legitimate interests

Declaring the contract void after five years of stable possession would have produced unjust consequences:

  • Disrupted the stability of civil transactions
  • Created opportunities for the more advantaged party to renege on their bargain
  • Imposed unfair loss on the party that had performed in good faith

Practical implications

For advising lawyers

  1. Drafting: still ensure full compliance with notarization and registration under Article 122 of the Housing Law 2014 and Article 167 of the Land Law 2013
  2. Litigation: Precedent 09 is essential authority when defending the position of a buyer who has performed but lacks formal notarization
  3. Transactional practice: counsel clients to preserve evidence of performance — handover minutes, payment records, debt-reconciliation memos

For adjudication

This precedent has been consistently applied in subsequent cases and extended to other contract types:

  • Land use right transfer contracts
  • Real-estate gift deeds
  • Capital-contribution agreements involving residential property

Continuity in the Civil Code 2015

Article 129 of the Civil Code 2015 has carried forward and refined the principle of Precedent 09:

"Where a civil transaction was entered into in writing as required, but the writing does not comply with the law, and one or all parties have performed at least two-thirds of the obligations in the transaction, the court shall, at the request of one or all parties, recognise the validity of that transaction."

The 2015 Code thus codified the precedent's principle — illustrating that precedents in Vietnam are not only a source of applied law but also a source of inspiration for legislative reform.

Limits and caveats

For all its importance, Precedent 09 has limits:

  1. The "two-thirds" threshold has not been fully clarified — courts continue to apply it inconsistently
  2. Does not cure other grounds of invalidity beyond formal defect (e.g. unlawful subject matter, lack of capacity)
  3. Requires affirmative evidence of performance — the party seeking recognition bears the burden

Conclusion

Precedent 09/2016/AL marks an important step in Vietnamese law: a shift from rigid formalism to a more substantive approach in contract dispute resolution. For practising counsel, mastery of this precedent and its companions (Precedent 04/2016, Precedent 14/2017) is foundational to effective litigation strategy in residential and land-use transactions — particularly in today's increasingly complex Vietnamese real-estate market.

In matters where Apolo Lawyers has invoked Precedent 09, the determinative factor has consistently been physical evidence of performance — bank records, signed handover minutes, real-estate tax filings — rather than the contract document alone.
