A real estate simulation, often referred to as a real estate counter-letter, is a discreet but powerful legal tool used in real estate transactions. This secret contract helps to clarify certain confidential aspects of a transaction, such as the rights of the parties or the agreed price. Often used for reasons of protection or flexibility, its use nevertheless requires great caution, due to the legal and fiscal implications, particularly with regard to tax authorities such as Revenu Québec and the Canada Revenue Agency.
What is a counter-letter in real estate?
In real estate law, a counter-letter is a secret document which modifies an apparent contract, often concealed, in order to alter or clarify certain clauses between the parties. In real estate law, it is used to establish a secret agreement between the signatories, which may differ from what is officially stated in the real estate transaction.
For example, the price indicated in the deed of sale may be adjusted in the counter-letter, or it may reveal the identity of the true owner of a property. The counter-letter is often linked to tax issues, and its use must be exercised with discernment, in compliance with the laws in force, in order to avoid penal, civil and criminal sanctions.
Origin and history: A brief history of the use of counter letters in real estate
The use of counter-letters in the real estate sector goes back many years. Historically, they have been used to circumvent certain legal provisions, notably in tax, civil liability and contractual matters. Because of their secretive nature, these secret agreements have often attracted the attention of tax authorities such as Revenu Québec or the Canada Revenue Agency.
In Quebec, their validity is governed by the Civil Code. Despite the consequences, counter-letters continue to be used in complex transactions.
Why use a counter-letter in real estate?
Protection of the parties: How the counter-letter protects the interests of the parties involved
One of the main reasons for using a real estate counter-letter is to protect the parties involved in a real estate transaction, particularly in terms of taxation. This document preserves the real rights of each party, while preventing them from being revealed to the general public. For example, if a buyer wishes to purchase a property in his or her own name, but a third party is the true owner, a counter-letter clarifies this arrangement between the parties. In the absence of disclosure to the tax authorities, in the event of a dispute, the tax authorities are considered bona fide third parties, and the apparent contract prevails.
This avoids future disputes, as each party is aware of its real commitments, even if these are not reflected in the official deed of sale. This method also makes it possible to discreetly manage certain aspects of a transaction that could be sensitive for legal or commercial reasons.
Confidentiality: The importance of discretion and confidentiality in certain real estate transactions
Confidentiality is another key reason for using a counter-letter. In some situations, the parties may not wish the financial details or structure of the agreement to be disclosed. This may include price adjustments on the purchase and sale of a condo, agreements on the management of a principal residence, or the future distribution of income generated by the property.
By keeping this information out of the official contract, the signatories ensure that the details of their agreement are not made public or subject to immediate external consequences.
Flexibility: How does the counter-letter allow for flexibility in agreements?
A real estate counter-letter also offers great flexibility in the way the parties can structure their hidden agreement. This type of document allows contractual provisions to be adapted without having to amend the main deed of sale or make it public. It is particularly useful in complex transactions where special arrangements need to be made, whether for tax planning reasons, to manage capital gains, or to organize the taxable income from the property.
How to draw up a counter-letter in real estate?
Writing steps: The different stages in writing an effective counter-letter
The drafting of a counter-letter requires several key steps to ensure its validity and protect the parties involved.
- Identification of parties: It is essential to clearly identify all parties involved, including the true owner of the property. Each person involved must be clearly named, with full contact details.
- Description of commitments: The counter-letter must accurately detail the actual commitments of each party. This includes modifications or clarifications to the terms of the main real estate contract, such as a price adjustment or future distribution of assets related to an income property.
- Specific conditions: Special provisions, such as the allocation of capital gains or tax obligations, must be specified. This avoids any subsequent confusion over the agreements, particularly in the event of an audit by tax authorities such as Revenu Québec or the Canada Revenue Agency.
- Signing and dating: As with any contract, the counter-letter must be signed and dated by all parties concerned to guarantee its validity. These signatures are essential if the agreement is to be legally recognized.
Practical advice: Mistakes to avoid and best practices
When drafting a counter-letter, it is crucial to avoid certain mistakes. Firstly, make sure that the terms of the counter-letter do not conflict with current laws or tax regulations.
In addition, the counter-letter should be drawn up between the parties in full transparency, with the help of a notary or qualified lawyers, to avoid potential legal or tax problems. Finally, it is advisable to keep a signed copy of the document, and to comply with the legal requirements of the Civil Code to ensure its validity.
Legality and validity of real estate counter-letters

Legal framework: Quebec legislation on counter-letters
In Quebec, the use of a simulation is governed by the Civil Code of Quebec. According to article 1451, a counter-letter is valid only if it does not infringe the rights of third parties and respects the laws in force. This means that the parties can agree to private arrangements, provided that such agreements are not contrary to public order, morality or tax obligations.
In addition, the counter-letter cannot be used to conceal information that should be declared to the tax authorities, such as an adjustment to the price of a real estate transaction. In other words, it must comply with tax law.
Validity in court : Under what circumstances can a counter-letter be contested?
A counter-letter can be challenged in court if it violates laws or is used to deceive third parties, such as creditors or tax authorities. For example, if the counter-letter is used to avoid reporting a capital gain or to reduce taxable income, government authorities may, depending on their interest, rely on the apparent contract or counter-letter. The counter-letter may be deemed null and void by a court under art. 317 C.c.Q.
The Quebec Court of Appeal has already invalidated hidden agreements designed to circumvent tax or legal obligations. It is therefore essential that the counter-letter be drafted in compliance with current legal and tax requirements.
Case studies: Concrete examples of validity and invalidity
A classic example of validity would be a counter-letter specifying the division of capital gains between co-buyers of a principal residence. If this agreement is transparent and declared, it will be valid. On the other hand, a counter-letter concealing the true owner of a property in order to circumvent the capital gains tax rules would be deemed invalid by the Court, and could result in sanctions by Revenu Québec and the Canada Revenue Agency.
Advantages and disadvantages of real estate counter-letters
Benefits: The main advantages for all parties involved are
The use of a counter-letter in real estate offers several advantages for the parties involved in a real estate transaction. Firstly, it allows great flexibility in agreements, notably by adjusting certain terms, such as price or capital gains distribution, without the need to modify the official contract.
This can be particularly useful in complex situations where specific financial or legal arrangements need to be made. What's more, the confidentiality afforded by the counter-letter protects the interests of the parties, by avoiding making public certain sensitive information, such as the identity of the true owner or specific conditions of the transaction.
Disadvantages : Potential risks and limitations
Despite its advantages, the counter-letter also has its drawbacks. Its secrecy can lead to litigation, particularly if it is not drafted rigorously, or if it is challenged in court. What's more, a counter-letter used to circumvent tax rules, such as the declaration of taxable income or capital gains, may be considered fraudulent by tax authorities such as Revenu Québec and the Canada Revenue Agency. It is therefore in the best interests of all parties to disclose their true intentions to the tax authorities. To do so, they can send a copy of the counter-letter when they file their tax returns following the date on which the counter-letter was signed.
Non-compliance of this kind may result in fines or even prosecution. In addition, the validity of the counter-letter may be called into question if it contravenes public policy or current legislation.
Benchmarking: Comparison with other legal tools
Compared with other legal tools, such as agreements or trusts, the real estate counter-letter stands out for its discretion and its ability to modify terms without affecting the main contract. However, unlike more transparent arrangements, it entails greater risks of litigation and appeal.
In conclusion, the counter-letter in real estate is a powerful tool for offering flexibility and confidentiality in real estate transactions, but it must be used with care and in compliance with the laws in force. If you are considering drafting one, or have questions about its tax and legal implications, it is essential to consult specialist lawyers.
