Power of attorney for a preliminary sale agreement

Signing a preliminary sale agreement (compromis de vente) by power of attorney (procuration) is an essential legal solution when a seller or a buyer cannot be physically present at this crucial stage of the property transaction. Whether because of expatriation, hospitalisation or professional commitments, a power of attorney for a compromis de vente makes it possible to keep to the sale timetable while meeting the legal requirements. This approach, governed by strict rules of the Civil Code, requires a thorough command of the conditions of validity and the associated risks in order to secure the parties' commitment. This complete guide covers all the legal, practical and strategic aspects of signing a compromis by power of attorney.

The legal foundations of a power of attorney in property matters

The principle of contractual representation

A power of attorney for a compromis de vente rests on the rules of agency (mandat) set out in Articles 1984 et seq. of the French Civil Code. The principal (seller or buyer) gives the agent the power to sign the preliminary sale contract in the principal's name and on the principal's behalf.

This contractual representation allows the agent to bind the principal legally on the same terms as if the principal had acted personally. A deed signed by power of attorney takes effect directly in the principal's estate.

The specific features of property law for signing a compromis by power of attorney

The compromis de vente is a preliminary contract that binds the parties definitively, subject to the usual conditions precedent. Signing such a deed by power of attorney requires a special and precise mandate, in accordance with Article 1988 of the French Civil Code, which provides that "a mandate framed in general terms covers only acts of administration".

The case law of the Cour de cassation requires the power of attorney to state expressly the transaction envisaged, the property concerned and the essential terms of the sale (price, payment terms, time limits). The essential elements of the deed are set out in our article on drafting a property power of attorney.

Practical example: For the sale of an 85 m² flat in Lyon 6th arrondissement at a price of €485,000, the power of attorney must specify these exact details and not merely refer to "a property in the Lyon area".

The conditions of validity of a power of attorney for a compromis de vente

Formal requirements for a secure signature of a compromis by power of attorney

Notarial deed or private deed

The law imposes no particular formality for drawing up a power of attorney relating to a compromis de vente. The deed may be drafted as a private deed, but notarial practice strongly recommends a notarial deed (acte authentique) for several reasons:

• Strengthened legal certainty through the involvement of a public officer • Verification of the identity and capacity of the principal • Custody of the original by the notary • Particular evidential weight in the event of a dispute

Mandatory content of the power of attorney

The power of attorney must state:

• Full identification of the principal (civil status, address, marital status) • Identification of the agent with contact details • Precise description of the property (address, land registry references, area) • Essential terms of the sale (fixed price or accepted price range) • Period of validity of the mandate • Powers conferred on the agent (signature only, or negotiation and signature)

Practical example: Madame Dubois, an expatriate in Canada, draws up a power of attorney for the sale of her house in Bordeaux. The power of attorney states: "sale between €350,000 and €365,000, maximum signing period of 3 months, authority to negotiate the conditions precedent within a margin of 15 days".

Substantive requirements

Capacity of the principal

The principal must have full legal capacity to grant the power of attorney. Protected adults (under guardianship (tutelle) or curatorship (curatelle)) may grant a power of attorney only with the authorisation of the guardianship judge or the family council, depending on the protection regime. The conditions for opening and the effects of the judicial protection measure (sauvegarde de justice), another protection regime for adults, are set out in our guide to that measure.

For married persons under a community property regime, signing a compromis by power of attorney sometimes requires the spouse's consent if the property is the family home or community property.

Free and informed consent

The principal must consent to the power of attorney with full knowledge of the facts. Any defect of consent (mistake, fraud, duress) affects the validity of the mandate and, as a result, that of the compromis signed by the agent.

Types of powers for an effective signature of a compromis by power of attorney

Power of attorney limited to signing

In this configuration, the agent has only the power to sign the compromis de vente on terms previously negotiated and set out in the power of attorney. The agent cannot amend any clause or accept different terms.

Advantages: • Total control by the principal over the terms of sale • Maximum protection against exceeding powers • Simple drafting of the power of attorney

Disadvantages: • Rigidity that is problematic if adjustments are needed • Risk of the signing failing if minor changes are required

Example: Monsieur Martin, in hospital, gives his son a power of attorney solely to sign a compromis at exactly €290,000, with no possibility of negotiating the price or the time limits.

Power of attorney with power to negotiate for signing a compromis

The agent may then discuss certain aspects of the sale within the limits set by the power of attorney. The document must precisely delimit the authorised scope of negotiation:

• Accepted price range (for example, a sale between €280,000 and €300,000) • Adjustable time limits (period for obtaining finance between 45 and 60 days) • Negotiable payment terms (share of personal funding, payment schedule)

Practical case: Madame Lefebvre authorises her brother to negotiate the sale of her Paris studio within a range of €185,000 to €195,000, with the possibility of granting a finance period of 45 to 75 days depending on the buyer's profile.

General power of attorney with limitations

Rarely used in practice, this formula gives the agent extensive powers while setting precise limits. It suits situations where the principal is durably prevented from acting (long-term expatriation, prolonged hospitalisation).

Revocation and termination of the mandate

Revocation by the principal

The principal may revoke the power of attorney at any time, in accordance with Article 2004 of the French Civil Code. This revocation must be notified to the agent and to the third parties concerned (notary, estate agency, counterparty) in order to be enforceable against them.

Practical arrangements for revocation: • Registered letter with acknowledgement of receipt to the agent • Notification to the notary handling the deed • Notification of the estate agency where applicable • Immediate effect but no retroactive effect on acts already performed

Automatic termination

The power of attorney terminates automatically in several cases:

• Expiry of the term set in the deed • Completion of the transaction for which it was granted • Death, incapacity or insolvency of the principal or the agent • Express revocation

Example: A power of attorney drawn up on 15 January for a period of 6 months terminates automatically on 15 July, even if no compromis has been signed in the meantime.

Risks and liabilities in signing a compromis by power of attorney

Liability of the agent

The agent incurs liability on several grounds:

Compliance with the limits of the mandate

Any exceeding of the powers conferred is an act performed without authority, which cannot be enforced against the principal unless expressly ratified later. An agent who exceeds those powers may be held civilly liable by the contracting third party. The risks of exceeding powers, for the principal as for the buyer, and the corresponding precautions are analysed in our study of the legal issues of a power of attorney for a compromis de vente.

Concrete case of exceeding powers: The agent, authorised to sell between €250,000 and €270,000, signs at €245,000 thinking they are "getting a good deal". This signature cannot be enforced against the principal, who may refuse to ratify the deed.

Duty to account

Article 1993 of the French Civil Code requires the agent to account to the principal for the assignment. This obligation includes:

• Return of the documents relating to the mandate • Justification of all acts performed • Detailed report of the negotiations conducted • Handing over of sums received (deposits, indemnities)

Liability of the principal

The principal remains liable for the commitments made by the agent within the limits of the powers conferred. This liability extends to the damaging consequences of non-performance of the compromis signed by power of attorney.

If the principal wrongfully withdraws after the compromis has been signed by the representative, the buyer may obtain damages or seek specific performance of the sale.

Worked example: If the principal refuses to honour a compromis validly signed by the agent for a property worth €300,000, the principal risks having to pay 10% of the sale price in damages, that is €30,000.

Protection of the counterparty

A third party who contracts with an agent has specific protections:

• Presumption of validity of the apparent mandate • Right to verify the extent of the agent's powers • Recourse against the principal within the limits of the mandate

Matrimonial specificities for signing a compromis by power of attorney

Family home and the spouse's authorisation

Where the property sold is the family home, Article 215 of the French Civil Code requires the authorisation of the seller's spouse, even if the spouse is not an owner. This authorisation must be given expressly and cannot be granted by power of attorney.

Key points: • Mandatory personal authorisation of the non-owner spouse • Impossibility of delegating this authorisation by power of attorney • Physical presence required of the spouse, or a separate notarial signature

In this specific case, the power of attorney can relate only to signing the compromis, the non-owner spouse having to consent personally to the sale of the family home.

Community property and joint management

For spouses married under a community property regime, the sale of community property requires the agreement of both spouses. If one of them cannot be present, that spouse may give a power of attorney to the other spouse or to a third party, but the power of attorney must state that it concerns community property.

Practical example: Monsieur and Madame Durand, married under the community property regime, jointly own an investment flat. Monsieur Durand, away on business, may give a power of attorney to his wife, but the deed must state explicitly that the property is community property.

Good notarial practice for signing a compromis by power of attorney

The notary's preliminary checks

Before receiving a compromis signed by power of attorney, the notary handling the deed must carry out several checks:

Authenticity of the power of attorney

• Verification of the principal's signature by comparison with other deeds • Checking the date and the conditions under which the mandate was issued • Verification that there has been no revocation

Extent of the powers

The notary ensures that the agent is acting within the limits of the agent's powers. Any change to the terms originally provided for requires the principal's express agreement or a sufficiently broad power of attorney.

Capacity and consent

• Verification of the principal's capacity at the time the power of attorney was drawn up • Checking for the absence of any apparent defect of consent • Validation of identity by official documents

Recommendations for securing the transaction

Recent power of attorney

A power of attorney more than six months old arouses distrust among practitioners. Beyond that period, it should be checked that the circumstances that led to the mandate being granted still exist.

Direct contact with the principal

Practice recommends a telephone or video call between the notary and the principal to confirm the principal's wishes, particularly if the power of attorney comes from a fellow professional who is geographically distant.

Ratification clause

Including a clause providing for express ratification of the deed by the principal within a set period strengthens the legal certainty of the transaction.

Notary's checklist: • Power of attorney less than 6 months old • Telephone contact with the principal • Verification of the powers granted • Check of the agent's identity • Ratification clause if necessary

Power of attorney in complex sales

Off-plan sale (VEFA) and signing a compromis by power of attorney

Off-plan sales have specific features that complicate the use of a power of attorney. Article R262-15 of the French Construction and Housing Code provides that the promise of sale in an off-plan sale (vente en état futur d'achèvement, VEFA) "is subject to the general-law rules on the sale of existing buildings" for certain aspects.

The power of attorney must then expressly provide for:

• Acceptance of the plans and the technical specification • Staged payment terms according to the progress of the works • Conditions for any price revision • Statutory guarantees (guarantee of perfect completion, ten-year guarantee)

Off-plan example: Madame Chen, living in Hong Kong, buys a new three-room flat (T3) in Nice with delivery expected in 18 months. Her power of attorney must authorise the agent to approve the final plans, accept any minor modifications and handle the staged calls for funds (30% on signing, 35% at watertight stage, 35% on delivery).

Sale with a complex condition precedent

Certain conditions precedent require active involvement by the buyer (obtaining a building permit, setting up a société civile immobilière). The power of attorney must provide for the powers needed to carry out the steps required.

Practical example: A buyer wishes to buy a 1,200 m² plot of land for €180,000 in order to build a commercial building on it. The sale is conditional on obtaining a building permit. The power of attorney must empower the agent to:

• File the permit application at the town hall • Supply the additional documents requested by the administration • Carry out all steps needed to obtain the authorisation • Receive the decision and handle any appeals

Acquisition by a company

Where the buyer is a legal entity, signing the compromis requires a double authorisation:

• Power of the company's legal representative • Possible power of attorney if that representative cannot be present

Complex case: SARL Immobilier Plus, run by Monsieur Leroy (manager), acquires a 150 m² commercial unit for €420,000. Monsieur Leroy, on a business trip, gives a power of attorney to his partner Monsieur Petit. The following must be checked:

• The articles of association authorising the acquisition with no limit on amount • The absence of any special authorisation required from the board of directors • The validity of the power of attorney between partners

Alternatives to signing a compromis by power of attorney

The unilateral promise of sale

In some cases, the unilateral promise of sale may be an alternative to signing a compromis by power of attorney. The seller alone is bound, the buyer keeping freedom until the option is exercised.

Advantages: • Total freedom for the buyer until the option is exercised • No risk of exceeding powers • Simple to implement

Disadvantages: • Unilateral commitment by the seller only • Possibility of the buyer withdrawing • Immobilisation indemnity to be provided for

Example: Monsieur Blanc, in hospital for 3 months, prefers to grant a unilateral promise of sale with a 60-day option rather than give a power of attorney, thereby keeping control of his final decision.

The right of first refusal agreement

Less binding than a promise of sale, the right of first refusal agreement (pacte de préférence) gives the beneficiary priority if a sale takes place. This solution suits situations where a definitive commitment is premature but the parties wish to formalise their intention.

Electronic signature

The development of the qualified electronic signature opens new prospects for private deeds. Although still uncommon in property matters, this solution makes it possible to avoid the use of a power of attorney for certain preliminary contracts.

Frequently asked questions on signing a compromis by power of attorney

Does a compromis signed by power of attorney have the same value as one signed personally?

Yes, provided the power of attorney is valid and the agent acts within the limits of the agent's powers. A compromis signed by power of attorney binds the principal on the same terms as a personal signature. Case law considers that a deed performed by the agent within the limits of the agent's powers takes effect directly in the principal's estate.

Can a power of attorney be given to a spouse to sign a compromis de vente?

It is legally possible, but it requires particular precautions. If the property is the family home, the non-owner spouse must give authorisation personally and cannot delegate it by power of attorney. For community property, each spouse may represent the other by power of attorney, but the notary must ensure that both spouses genuinely consent.

How long does a power of attorney remain valid for signing a compromis?

No provision sets a maximum period, but notarial practice considers that a power of attorney more than six months old calls for vigilance. Beyond that period, it should be verified that the circumstances that led to the mandate being granted still exist and that the principal's wishes have not changed.

Recommended periods according to the situation: • Temporary hospitalisation: 3 months maximum • Business trip: 2 months maximum
• Short expatriation: 6 months maximum • Long expatriation: Renewal every 12 months

What happens if the agent exceeds their powers when signing?

A deed performed without authority or beyond the powers conferred cannot be enforced against the principal, unless the principal expressly ratifies it. The agent then incurs personal liability to the counterparty. In practice, this situation creates legal uncertainty that may lead to the sale being annulled.

Financial consequences: The agent may be ordered to pay damages corresponding to the loss suffered by the buyer (generally 5 to 10% of the sale price).

Is it compulsory to go before a notary to draw up a power of attorney?

No, a power of attorney in the form of a private deed is legally valid. However, a notarial deed offers significant advantages:

Notarial deed: • Verification of the principal's identity and capacity • Secure custody of the original
• Strengthened evidential weight in the event of a dispute • Cost: €80 to €150 depending on complexity

Private deed: • Identical legal validity • Lower cost (free or lawyer's fees) • Higher risk of challenge • Custody to be arranged by the parties

Can an agent delegate their powers to another person?

In principle no, unless expressly authorised in the original power of attorney. Article 1994 of the French Civil Code lays down the principle that "the agent may not, without express permission, appoint a substitute in the agent's place". This prohibition on substitution aims to preserve the relationship of personal trust between principal and agent.

How can a power of attorney that has already been used to sign a compromis be revoked?

If the compromis has already been validly signed by the agent, later revocation of the power of attorney does not affect the validity of the deed performed. The principal remains bound by the compromis signed by the representative. Revocation can usefully take place only before the deed for which the power of attorney was granted has been performed.

Revocation procedure before signing: • Registered letter to the agent • Notification to the notary
• Notification of all third parties concerned • Immediate effect of the revocation

Signing a compromis by power of attorney is an effective legal mechanism but one that demands rigour and forward planning. Its validity depends on scrupulous compliance with the conditions of form and substance, in particular the precision of the powers conferred on the agent. Given the considerable financial stakes of a property transaction, it is essential to favour the notarial deed and to use an experienced notary. Before using a power of attorney for a compromis de vente, assess with your adviser the possible alternatives and the specific features of your marital and wealth situation. Signing a compromis by power of attorney, properly implemented, secures your property project even where you are personally prevented from attending.
