A property amendment is a legal document that modifies one or more clauses of an existing contract, whether a preliminary sales agreement, lease or deed of sale, without cancelling or replacing the original contract. In Paris, the most common amendments relate to preliminary sales agreements and concern postponing the signing date, modifying the price after discovering a defect, or extending the deadline for fulfilling a condition precedent.
In the context of a property purchase in Paris, it is common for an amendment to become necessary between the signing of the preliminary agreement and the final deed. A delay in obtaining the loan, an unfavourable supplementary diagnostic or a change in the seller’s schedule are all situations that require a formal modification of the preliminary agreement. Understanding how amendments work means giving yourself the ability to react quickly and protect your interests.

What is a property amendment?
An amendment is a legal act that is ancillary to a principal contract. It cannot exist alone: it always attaches to the contract it modifies. Legally, the amendment supplements or alters certain clauses while keeping the rest of the contract in force.
In property, there are mainly three types of amendments. The amendment to the preliminary sales agreement is the most common in a transaction. The lease amendment modifies the terms of an existing rental contract. The amendment to the authentic deed, less common, intervenes after the sale to correct a material error or adjust a clause.
Difference between an amendment and a rectification deed
An amendment voluntarily modifies a clause of the contract by mutual agreement between the parties. A rectification deed corrects a material error (typo, surface error, incorrect lot number) without changing the parties’ intention. The distinction matters because a rectification deed does not always require the agreement of both parties.
The most common use cases in Paris
Having supported over 1,200 transactions since 2011, our team of apartment hunters has encountered many situations requiring an amendment. Here are the most common.
Postponement of the signing date for the final deed
This is the most frequent reason for an amendment. The scheduled date for signing at the notary must be pushed back because the loan application is taking longer than expected, technical diagnostics have revealed a problem requiring further investigation, the seller has not yet found their next home, or the notaries need additional time to gather documents (mortgage status, urban pre-emption rights, etc.).
In Paris, the period between the preliminary agreement and the final deed averages 3 to 4 months. But it is not uncommon for this to extend to 5 or 6 months, particularly for older buildings in central Paris where legal situations are more complex (easements, shared walls, air rights).
Modification of the sale price
After signing the preliminary agreement, a discovery may justify price renegotiation. A worse energy rating than advertised, the discovery of a hidden defect during technical counter-viewings, a facade restoration voted in a general meeting between the preliminary agreement and the deed, or a surface area error identified by the Carrez measurement: beyond a 5% discrepancy, the buyer can demand a proportional price reduction.
The amendment formalises the newly agreed price and the reasons for the change. Without an amendment, the modification has no legal value, even if both parties agree verbally.
Extension of a condition precedent
The conditions precedent in the preliminary agreement, such as obtaining the loan, absence of pre-emption, or obtaining a building permit, have specific deadlines. If the initial deadline is insufficient, an extension amendment prevents the preliminary agreement from lapsing. For example, if the financing condition precedent is set at 45 days and the bank has not yet issued its offer, an amendment extending this to 60 or 75 days protects the buyer.
Addition or removal of a buyer
It sometimes happens that between the preliminary agreement and the deed, the buyer composition changes. A couple decides to purchase through an SCI (property company), a co-borrower withdraws from the project, or an investor wishes to add a partner. The amendment allows the buyers’ identity to be changed without jeopardising the sale.
How to draft an effective amendment
Drafting a property amendment follows precise formal rules to be legally enforceable.
Mandatory information
The amendment must contain a reference to the original contract with its signing date and the parties’ names, the precise identification of the clause being modified citing the relevant article or paragraph, the new wording of the clause with the formula “clause X is replaced by the following provision: …”, the effective date of the modification, and the signature of all parties to the original contract.
Form and formalities
For a preliminary sales agreement signed privately (between parties or at an agency), the amendment can follow the same form. However, in Paris, we systematically recommend having the amendment drafted and signed at the notary, even for a privately signed preliminary agreement. The cost is minimal, often included in the file fees, and the legal security is significantly greater.
For a preliminary agreement signed as an authentic deed, the amendment must be notarised.
Amendments and deadlines: what you need to know
The question of deadlines is central when an amendment is needed, especially within the tight schedule of a Parisian transaction.
Withdrawal period and amendments
A frequently overlooked point: signing an amendment that substantially modifies the sale conditions (price, surface area, property description) can trigger a new 10-day withdrawal period for the buyer. This applies when the amendment concerns a determining factor of consent. By contrast, a simple date postponement does not trigger a new withdrawal period.
Impact on financing
Any amendment modifying the price must be communicated to the bank. If the price decreases, the loan amount will be adjusted. If the price increases, the buyer must verify that their borrowing capacity covers the difference. Some banks require a new agreement in principle, which can add 2 to 3 weeks to the schedule.
Response time
Unlike a purchase offer, there is no legal deadline for responding to an amendment proposal. In practice, set a response deadline of 5 to 10 working days in the letter accompanying the amendment proposal. An experienced apartment hunter, familiar with transactions in arrondissements like the 3rd or the 9th, can accelerate the negotiation and drafting of the amendment through their relationships with local notaries and agents.
The limits of amendments
An amendment is not a universal solution. In certain situations, it is preferable to redo the preliminary agreement entirely or, in extreme cases, to withdraw from the transaction.
Modifications that are too substantial
If all the sale conditions have changed, including price, buyers, deadlines and conditions precedent, a new deed is clearer and safer than a stack of amendments. Beyond 3 amendments on a single preliminary agreement, legal readability deteriorates and the risk of challenge increases.
Refusal by one party
An amendment requires the agreement of all parties. If the seller refuses a modification requested by the buyer (or vice versa), the amendment cannot be imposed. The options are then either to maintain the initial terms of the preliminary agreement, or to consider the preliminary agreement lapsed if the conditions can no longer be met.
Amendment and sale file preparation
When an amendment modifies the financial terms or the buyer composition, the sale file submitted to the notary must be updated accordingly. Technical diagnostics and co-ownership documents remain valid, but the loan offer, insurance certificate and identity documents must reflect the new situation.
FAQ
Can an amendment change the sale price of a property?
Yes, an amendment to the preliminary sales agreement can change the price, provided both parties agree. This is common when a diagnostic reveals a defect not visible during the viewing, for example a worse energy rating than expected. The amendment must specify the new price and the reason for the change.
Do you need to go back to the notary to sign an amendment?
Not necessarily. An amendment to a privately signed preliminary sales agreement can be signed between the parties without a notary. However, if the preliminary agreement was signed as an authentic deed (at the notary’s), the amendment must follow the same form. In Parisian practice, going through the notary is recommended to secure the modification.
How many amendments can be made to a single preliminary sales agreement?
There is no legal limit to the number of amendments. However, beyond 2 or 3, the contract’s readability may be compromised. If the modifications are too numerous or substantial, it may be preferable to draft a new preliminary agreement.
