The review distinguishes an immaterial mistake as to motives from a material mistake, taking into account the position of the transaction participant, and also sets out the conditions for challenging a transaction entered into under the influence of fraud by third parties.
Paragraph 1 · A mistake as to motives does not vitiate a transaction
The seller had expected a particular method of payment, but a mistake as to the motives for the transaction is not among the material mistakes listed in paragraph 2 of Article 178 of the Civil Code of the Russian Federation. The court must take into account the good faith of the other party and that party's ability to recognise the mistake, ensuring both parties an equal level of protection.

Paragraph 2 · The materiality of a mistake is assessed on an individual basis
The materiality of a mistake is not assessed in the abstract: the court evaluates the transaction participant's circumstances, state of health and the personal significance of the transaction to that participant. In the case discussed in the review, the seller was an elderly woman living alone who was dealing with a professional participant in the real-estate market, and this affected the assessment.

Paragraph 7 · Fraud by third parties and the buyer’s awareness
The fraud was committed by third parties, but the transaction is voidable if the buyer knew or should have known about the fraud. The buyer’s awareness was established, among other things, by the fact that the parties acted through the same real estate agency, which facilitated the transaction.

The judicial acts in the case described in the factual background were upheld by the court of first instance, the appellate court and the cassation court; the case did not reach the Supreme Court. The case details are not provided in the review, so it is impossible to cite a specific act.
Paragraph 8 · Bilateral restitution in cases of fraud
Having declared a transaction invalid under Article 179(2) of the Civil Code of the Russian Federation, the court applies bilateral restitution: each party returns what it received. The court may decline to apply the consequences of invalidity only in cases expressly specified by law, and must provide reasons.

This section addresses the allocation of the burden of proof, the role of court-appointed expert examination, the standing of plaintiffs, and the assessment of a receipt issued by a person unable to understand the significance of their actions.
Paragraph 1.1 · Article 177 of the Civil Code: the burden of proof lies with the plaintiff
A plaintiff relying on Article 177(1) of the Civil Code of the Russian Federation must prove the person’s inability to understand the significance of their actions at the time of the transaction. Refusal to undergo a court-ordered examination of the person’s mental condition (Article 79(3) of the Civil Procedure Code of the Russian Federation) may result in the claim being dismissed.

Paragraph 3 · A mental disorder may be established only by expert examination
The question whether a person was capable of understanding the significance of their actions requires special expertise and is determined on the basis of an expert examination. If the court rejects an expert opinion, it must give reasons for its disagreement and order a repeat or additional examination rather than substitute its own assessment for the expert’s conclusions.

Paragraph 4 · Who has standing to challenge a transaction under Article 177 of the Civil Code
The class of plaintiffs under Article 177 of the Civil Code of the Russian Federation is limited: while a legally capable citizen is alive, their transaction may not be challenged by relatives whose rights were not affected by it. Heirs acquire that right only after the citizen’s death.
Primary source in the database: direct primary source: Plenum of the Supreme Court of the Russian Federation Resolution No. 9 (2012), para. 73.
Paragraph 5 · Remission at the time of the transaction precludes invalidity
A diagnosis does not, in itself, taint a transaction. If the condition was in remission when the transaction was made and did not deprive the citizen of the ability to understand the significance of their actions, there are no grounds for invalidity.
Primary source in the database: The judicial acts in the case described in the factual background were upheld by the court of first instance, the appellate court and the cassation court; the case did not reach the Supreme Court. The case details are not provided in the review, so it is impossible to cite a specific act.
Paragraph 11 · A receipt issued by an incapable person does not prove payment
If the seller was unable to understand the significance of their actions at the time of the transaction, a receipt issued by the seller is not conclusive proof that the money was received. The court assesses it together with the other evidence and must give reasons for its conclusion.

Paragraph 9 · Community property: the buyer’s awareness is required
To challenge a transaction made by one of the former spouses under Article 253(3) of the Civil Code of the Russian Federation, it must be proved that the buyer knew or clearly should have known that the seller lacked authority. A mere reference to Article 10 of the Civil Code of the Russian Federation, without establishing the buyer’s awareness, is insufficient.

Paragraph 10 · A sham transaction requires both parties to lack intent
A sham transaction presupposes that each party lacked the intention to create legal consequences. The buyer’s actual performance of the transaction, including payment from mortgage-loan funds, rules out a finding that the transaction was sham.

The judicial acts in the case described in the factual background were upheld by the court of first instance, the appellate court and the cassation court; the case did not reach the Supreme Court. The case details are not provided in the review, so it is impossible to cite a specific act.
Paragraph 6 · An heir may seek review of the case
Succession is permissible at any stage of civil proceedings; therefore, an heir of the plaintiff may apply for review of final judicial decisions on the basis of newly discovered or new circumstances (Articles 44 and 392 of the Civil Procedure Code of the Russian Federation).

Positions concerning unequal counter-performance, suspect transactions, enforcement immunity for a sole residence, and the powers of the financial administrator.
Paragraph 12 · Unequal value in bankruptcy: not only the price
A formal deviation of the contractual price from the market price by more than 20 percent is insufficient, by itself, to establish unequal counter-performance under Article 61.2(1) of the Bankruptcy Law. The court takes into account all the circumstances surrounding the transaction.
Primary source in the database: direct primary source: Judicial Chamber for Economic Disputes Ruling No. 307-ЭС25-13338 (2026).
Paragraph 13 · A gift as a suspect transaction
A gift of residential premises to a close relative shortly before bankruptcy, where outstanding obligations exist, is voidable under Article 61.2(2) of the Bankruptcy Law. The awareness of a donee who is an interested person is presumed (Article 19(3) of the Law).
Primary source in the database: direct primary source: Judicial Chamber for Economic Disputes Ruling No. 308-ЭС19-4372 (2019).
Paragraph 14 · Enforcement immunity bars a challenge
The purpose of challenging transactions in bankruptcy is to replenish the bankruptcy estate. If a returned share in a sole residence would be protected by enforcement immunity (Article 446 of the Civil Procedure Code of the Russian Federation), challenging the transaction would serve no purpose and the transaction is not declared invalid.
Primary source in the database: direct primary source: Review of Case Law in Bankruptcy Cases Involving Individuals (2025), para. 20. The judicial acts in the case described in the factual background were upheld by the court of first instance, the appellate court and the cassation court; the case did not reach the Supreme Court. The case details are not provided in the review, so it is impossible to cite a specific act.
Paragraph 15 · After bankruptcy, only the administrator may register the transfer
From the date a citizen is declared bankrupt, they lose the right to dispose of property comprising the bankruptcy estate. Registration of a transfer of title to their real estate may be carried out only upon an application by the financial administrator (Article 213.25(5) and (7) of the Bankruptcy Law).

Paragraph 16 · A court decision is sufficient to restore the register entry

Paragraph 20 · The registrar does not review a notarised transaction
The registrar’s legal review does not encompass verification of the legality of a notarised transaction (Article 59(2) of the Law on State Registration of Real Estate). Notice to a co-owner under Article 250 of the Civil Code of the Russian Federation is deemed delivered in accordance with Article 165.1 of the Civil Code of the Russian Federation.
