Power of Attorney to Sell Real Property: Guide 2026

Selling a property requires signing the deed of sale at the notary's office. When the owner cannot or does not wish to travel — expatriation, illness, professional constraints — the power of attorney to sell a property allows them to entrust the signing to a trusted representative. Contrary to a common belief, article 1985 of the Code civil does not require a notarised form: a private power of attorney is valid for an ordinary sale. This article details the possible forms, what the notary may require in practice, the essential clauses, the remote notarised power of attorney, and the digital tools useful around the transaction.

Notarised or private power of attorney: what article 1985 really says

Under article 1985 of the Code civil, a mandate may be given by authentic instrument, by private deed — even by simple letter — or verbally. The text imposes no formal requirement linked to the deed the representative will subsequently sign. The sale of a property is formed by the parties' agreement on the item and the price (article 1583 of the Code civil); it is executed in authentic form because any deed subject to land registration formalities must be so executed (article 4 of decree no. 55-22 of 4 January 1955). This requirement concerns the deed of sale, not the power given to the representative.

Consequence: for an ordinary property sale, a private power of attorney is sufficient. In practice, the notary handling the sale usually prepares the draft power of attorney themselves and often requires that the principal's signature be legalised (at the town hall or consulate) to confirm their identity. Some notarial offices prefer a notarised power of attorney for sensitive files: this is a matter of caution to be anticipated, not a legal requirement of validity.

When the power of attorney must be notarised

The authentic form becomes mandatory when the deed the representative will sign must itself be authentic to be valid. This is notably the case for:

• Off-plan sales (VEFA) and sales of properties to be renovated, whose contract must be concluded by authentic instrument.
• The creation of a contractual mortgage, often provided for in the purchase deed financed by a loan.
• A gift and its acceptance, which must take the notarised form (articles 931 and 933 of the Code civil).

For the sale of an existing home by a private individual, none of these rules apply: the choice of form depends on how the file is organised and the requirements of the notarial office.

From abroad: consulate, local notary or remote power of attorney

When the principal resides outside France, several routes are available:

• The consular power of attorney: French consulates exercise notarial functions on behalf of French nationals and can receive a power of attorney or legalise the signature on a private power of attorney. The deed is then issued by a French authority and does not need to be apostilled.
• The power of attorney received by a local notary in the country of residence, apostilled in accordance with the Hague Convention of 5 October 1961 or legalised depending on the country, and accompanied if necessary by a sworn translation.
• The remote notarised power of attorney (article 20-1 of decree no. 71-941), which allows the principal to sign from home: this is detailed further below.

In all cases, the notary handling the sale must have the power of attorney, in original form or in the form they have accepted, before the signing appointment.

Contents of a valid property power of attorney

A power of attorney to sell must be express: article 1988 of the Code civil specifies that a mandate drafted in general terms covers only acts of administration, and that an express mandate is required to dispose of property. A general power of attorney “to manage my affairs” therefore does not allow the sale of a property.

Essential clauses

The power of attorney, whatever its form, must at minimum mention:

• The principal's full identity (surname, first names, date and place of birth, address, marital status).
• The representative's full identity.
• The precise description of the property: address, nature, land registry references, co-ownership lots where applicable.
• The minimum accepted price and the terms of the sale (conditions precedent, payment terms).
• The ancillary powers: signing the preliminary contract, collecting the price, giving receipt, carrying out the necessary formalities.
• Where applicable, a validity period, which the law does not require but which limits the principal's commitment.

Restrictions and exceeding of authority

The principal may limit the representative's powers: minimum price, deadline, choice of buyer. An act carried out beyond these powers is not binding on the principal, unless the buyer legitimately believed in the reality of the representative's powers, particularly because of the principal's conduct; the principal may also ratify the act afterwards (article 1156 of the Code civil).

Practical procedure: from drafting to signing

The power of attorney is prepared at the same time as the sale: it is often the document that delays the signing appointment when it is started too late.

Step 1: obtain the draft power of attorney

The notary handling the sale sends the seller a draft power of attorney tailored to the file. At the same time, they verify the seller's legal capacity (absence of guardianship or supervised administration) and the status of the property (joint ownership, split ownership, matrimonial property regime).

Step 2: sign the power of attorney

Depending on the form chosen, the principal signs the private power of attorney and has the signature legalised, signs it at the consulate, before a notary, or remotely via the procedure under article 20-1 of decree no. 71-941. They then send it to the notary, in original form where required.

Step 3: review by the notary

Before the deed of sale is signed, the notary checks the regularity of the power of attorney, its scope (does it cover this property, at this price?) and its validity over time. In case of doubt, they request confirmation or a new power of attorney.

Step 4: signing the deed of sale

The representative attends the notarial office with an identity document and signs the authentic deed on behalf of the seller, within the limits of their powers. The power of attorney is appended to the deed.

For preparatory deeds — the sale agreement, unilateral promise to sell — the electronic signature in property transactions can be used, with a service compliant with the eIDAS regulation. Certyneo offers an advanced electronic signature for these private deeds prior to the sale.

Special cases: joint ownership, property companies and split ownership

The power of attorney takes on additional importance when the property has several owners or belongs to an asset-holding structure.

Sale of jointly owned property

The sale of jointly owned property generally requires the consent of all co-owners (article 815-3 of the Code civil). Anyone who cannot be present grants a power of attorney, in the form accepted by the notary. Failing agreement, co-owners holding at least two-thirds of the rights may ask the court for authorisation to sell (article 815-5-1). For the management of representation mandates between distant co-owners, secure digital solutions make it easier to circulate documents.

Sale by a property-holding company (SCI)

When the property belongs to a civil property company (SCI), it is the manager who represents the company, within the limits set by the articles of association. If these require a decision by the partners, a meeting must authorise the sale beforehand, and the minutes are appended to the deed. If the manager delegates the signature, their power of attorney is based on these powers. Electronic signature for legal firms offers useful traceability here for meeting minutes and representation mandates.

Sale of a property held in usufruct and bare ownership

The transfer of full ownership of a property with split ownership requires the agreement of both the usufructuary and the bare owner; each can grant a power of attorney separately. The distribution of the price between usufruct and bare ownership is agreed between them, often on the basis of the tax scale under article 669 of the General Tax Code.

The remote notarised power of attorney and digital tools

While the deed of sale remains an authentic instrument signed before a notary, several surrounding documents can be signed electronically.

Sale agreement and preliminary contract

The unilateral promise to sell and the preliminary sale agreement are private deeds: they can be signed electronically, as an electronic document has the same evidentiary value as a paper document provided its author is identified and its integrity guaranteed (articles 1366 and 1367 of the Code civil). The level of signature is chosen according to the stakes involved; the complete guide to electronic signature details the simple, advanced and qualified levels.

Estate agency mandates

The sale mandate entrusted to a real estate agent (Hoguet law of 2 January 1970) must be in writing; it can be signed electronically. To choose a tool, Certyneo's comparison of electronic signature solutions presents the offers available on the French market.

The remote notarised power of attorney

Since decree no. 2020-1422 of 20 November 2020, a notary can establish a power of attorney on an electronic medium without the principal being physically present (article 20-1 of decree no. 71-941): the principal communicates with the notary by video call, then signs using a qualified electronic signature. Since 1 October 2025 (decree no. 2025-538 of 13 June 2025), their identification must go through the system of the Conseil supérieur du notariat, operated with Docaposte. Only the power of attorney can be established in this way: the deed of sale itself must be signed before the notary, with the seller able to appear before a second notary connected by video call (article 20 of the same decree). To estimate the gains from digitisation, Certyneo's electronic signature ROI calculator provides a personalised estimate.

Revocation and termination of the mandate

The principal can revoke the power of attorney at any time as long as the representative has not signed (article 2004 of the Code civil). Revocation notified only to the representative is not binding on third parties who are unaware of it (article 2005): the notary handling the sale must therefore also be informed. The mandate also ends upon the death, placement under guardianship, or insolvency of the principal or the representative (article 2003).

Legal framework applicable to the property power of attorney

The power of attorney to sell a property falls under mandate law, notarial law and, for the surrounding documents, electronic signature law.

Code civil

• Article 1984: defines the mandate, by which the principal gives the representative the power to do something on their behalf.
• Article 1985: a mandate may be given by authentic instrument, by private writing, even by letter, or verbally. It does not require the notarised form for a property sale.
• Articles 1987 and 1988: distinguish between special and general mandates, and require an express mandate to dispose of or mortgage property.
• Article 1156: governs the effect of an act carried out by a representative without authority or beyond their powers.
• Articles 2003 to 2010: termination of the mandate (revocation, renunciation, death, guardianship) and its effects on third parties.
• Articles 815-3 and 815-5-1: consent of co-owners and judicial authorisation to sell.

Notarial law and land registration

• Decree no. 55-22 of 4 January 1955, article 4: any deed subject to land registration must be executed in authentic form — it is this rule that requires a notary for the deed of sale.
• Decree no. 71-941 of 26 November 1971: deeds drawn up by notaries, including on electronic media (articles 16 to 20-1).
• Decree no. 2020-1422 of 20 November 2020 and decree no. 2025-538 of 13 June 2025: remote notarised power of attorney and identification via the Conseil supérieur du notariat's system.

Electronic signature

• eIDAS Regulation no. 910/2014: three levels of electronic signature (simple, advanced, qualified); the qualified electronic signature has a legal effect equivalent to a handwritten signature (article 25).
• Articles 1366 and 1367 of the Code civil: an electronic document has the same evidentiary value as a paper document; the signature identifies its author and expresses their consent, and its reliability is presumed for a qualified signature.

Legal risks

An insufficient power of attorney — powers that are too general, a poorly described property, an unrespected minimum price — exposes the parties to a deed that is not binding on the seller, absent ratification, and to disputes with the buyer. A notary who executes a deed on the basis of an irregular power of attorney incurs professional civil liability. In the event of fraud, the offence of fraud is punishable by five years' imprisonment and a fine of €375,000 (article 313-1 of the Penal Code), forgery and use of forgery by three years and €45,000 (article 441-1): this is the reason behind signature legalisation and the identity checks required by notaries.

Usage scenarios: the property power of attorney in practice

Scenario 1: an expatriate owner sells their apartment

An owner who has lived in South-East Asia for three years is selling a two-room flat in France and cannot return for the signing. The notary sends them a draft power of attorney designating their brother as representative, with a minimum price. The owner signs it at the French Consulate General, which legalises their signature, then sends it in original form to the notary. The file is ready in about three weeks, without any travel: the savings on travel and accommodation amount to thousands of euros.

Scenario 2: sale of jointly owned property between heirs in three countries

Four heirs jointly own a house received through inheritance; two live in France, one in Belgium and one in Canada. The two heirs living abroad each sign their power of attorney at the French consulate, in Brussels and Montreal, which legalises their signature. The heirs residing in France sign in person, and one of them represents the Belgian heir. The sale is signed at a single appointment, whereas coordinating travel could have delayed it by several months.

Scenario 3: a family property company sells a commercial premises

An SCI decides, at a meeting, to sell a 180 sq. m commercial premises. The manager, hospitalised on the scheduled date, delegates the signing to a partner through a special power of attorney: limited to this property, to a minimum price and to a six-month period, and accompanied by the meeting minutes. The notary accepts the file, and the sale takes place within the deadline set by the preliminary agreement, without any late-payment penalty.

Frequently asked questions

Can a private power of attorney be sufficient?

Yes, for an ordinary property sale: article 1985 of the Code civil allows a mandate to be given by private writing, and only the sale itself must be executed by the notary in authentic form. The notary often requires the signature to be legalised, and some offices prefer a notarised power of attorney. The authentic form is, however, mandatory for an off-plan sale, a mortgage or a gift.

Does a general power of attorney allow a sale?

No. Article 1988 of the Code civil is explicit: a mandate drafted in general terms covers only acts of administration, and an express mandate is required to dispose of or mortgage property. A power of attorney “to manage my affairs” therefore does not allow a sale. The mandate must identify the property, the power to sell and, preferably, the conditions under which the representative may commit.

How can a power of attorney be established from abroad?

Three routes: signing at the French consulate, which receives the power of attorney or legalises the signature; signing before a local notary, with an apostille or legalisation depending on the country and a sworn translation if necessary; or using the remote notarised power of attorney. This is often the longest step in the file: it should be started as soon as the price is agreed.

Can the power of attorney be revoked?

Yes, at any time as long as the representative has not carried out the act. However, revocation notified only to the representative is not binding on third parties who are unaware of it: the notary handling the sale must be expressly informed. The mandate also ends upon the death or placement under guardianship of either party.

Can the sale be signed remotely without a power of attorney?

Not from home. The deed of sale must be signed before a notary; a seller who is far away can, however, appear before another notary, connected to the notary handling the sale by video call (article 20 of decree no. 71-941). If they cannot go to any notary, they grant a power of attorney — and this power of attorney can, since 2020, be established remotely.

Conclusion

The power of attorney to sell a property is not a mere formality: its drafting determines how smoothly the sale proceeds. Article 1985 of the Code civil leaves the choice of form open — a private power of attorney is valid for an ordinary sale — but the notary may require a legalised signature, and the authentic form is mandatory for an off-plan sale, a mortgage or a gift. An express mandate, a precise description of the property and price, and a form agreed in advance with the notarial office make for an unassailable power of attorney.

While the deed of sale remains a notarised deed, the surrounding steps — preliminary agreement, agency mandates, SCI meeting minutes — can be digitised through an electronic signature compliant with the eIDAS regulation. Certyneo supports property professionals, notarial offices and investors with signature tools and an interface designed for multi-signatory deeds.
