Power of Attorney to Sell Real Estate: 2026 Guide

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

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

Under article 1985 of the French Civil Code, a mandate may be given by authentic deed, by a deed under private signature — even by simple letter — or verbally. The text imposes no formal requirement linked to the deed that 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 French Civil Code); it is executed in authentic form because any deed subject to land registration must be so executed (article 4 of decree no. 55-22 of 4 January 1955). This requirement applies to the deed of sale, not to the power granted to the representative.

Consequence: for an ordinary property sale, a power of attorney under private signature is sufficient. In practice, the notary handling the sale usually prepares the draft power of attorney themselves and often asks that the principal's signature be certified (at the town hall or consulate) to confirm their identity. Some notarial offices prefer a notarised power of attorney for sensitive cases: this is a precautionary requirement to plan for, not a condition of validity set by law.

When the power of attorney must be notarised

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 the sale of a property to be renovated, whose contract must be concluded by authentic deed.
• The creation of a conventional mortgage, often provided for in the purchase deed financed by a loan.
• Gifts and their acceptance, which are subject to notarised form (articles 931 and 933 of the French Civil Code).

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

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

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

• The consular power of attorney: French consulates perform notarial functions for French nationals and may receive a power of attorney or certify the signature of a power of attorney under private signature. The deed then originates from a French authority and does not need to be apostilled.
• The power of attorney executed 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 where 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, either in original 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 French Civil Code states 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 least state:

• The full identity of the principal (surname, first names, date and place of birth, address, marital status).
• The full identity of the representative.
• 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: to sign the preliminary contract, receive the price, give a receipt, and carry out the necessary formalities.
• Where applicable, a period of validity, which is not required by law but limits the principal's commitment.

Restrictions and exceeding 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 French Civil Code).

Practical procedure: from drafting to signing

The power of attorney is prepared alongside 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 curatorship) and the status of the property (joint ownership, split ownership, matrimonial regime).

Step 2: sign the power of attorney

Depending on the form chosen, the principal signs the power of attorney under private signature and has their signature certified, 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 where required.

Step 3: review by the notary

Before the deed of sale is signed, the notary checks the validity of the power of attorney, its scope (does it indeed 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 identification and signs the authentic deed on the seller's behalf, within the limits of their powers. The power of attorney is appended to the deed.

For preparatory documents — preliminary sale agreements, unilateral promises to sell — electronic signature in real estate may be used, with a service compliant with the eIDAS regulation. Certyneo offers an advanced electronic signature for these private-signature deeds preceding the sale.

Special cases: joint ownership, property companies and split ownership

The power of attorney takes on additional significance when the property has several owners or belongs to a 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 French Civil Code). 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 managing representation mandates between co-owners living far apart, secure digital solutions make document circulation easier.

Sale by a property holding company (SCI)

When the property belongs to a société civile immobilière, the manager represents the company, within the limits set out in the articles of association. If these require a decision by the members, a general meeting must authorise the sale beforehand, and the minutes are appended to the deed. If the manager delegates signing authority, their power of attorney relies on these powers. Electronic signature for law firms provides 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 may grant a power of attorney separately. The distribution of the price between usufruct and bare ownership is agreed between them, often based on the tax scale set out in article 669 of the French General Tax Code.

The remote notarised power of attorney and digital tools

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

Preliminary sale agreement and unilateral promise to sell

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

Estate agency mandates

The sales mandate given to an 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 draw up a power of attorney in electronic form without the principal being physically present (article 20-1 of decree no. 71-941): the principal communicates with the notary by video conference, then signs using a qualified electronic signature. Since 1 October 2025 (decree no. 2025-538 of 13 June 2025), identification must be carried out via the system operated by the Conseil supérieur du notariat, run with Docaposte. Only the power of attorney can be executed in this way: the deed of sale itself must be signed before a notary, with the seller able to appear before a second notary connected by video conference (article 20 of the same decree). To estimate the gains from digitalisation, Certyneo's electronic signature ROI calculator provides a personalised estimate.

Revocation and termination of the mandate

The principal may revoke the power of attorney at any time as long as the representative has not signed (article 2004 of the French Civil Code). 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 property powers of attorney

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

French Civil Code

• Article 1984: defines the mandate, whereby the principal grants the representative the power to do something on their behalf.
• Article 1985: a mandate may be given by authentic deed, by a document under private signature, even by letter, or verbally. It does not require 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 drawn up 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 in electronic form (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 system operated by the Conseil supérieur du notariat.

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 that of a handwritten signature (article 25).
• Articles 1366 and 1367 of the French Civil Code: an electronic document has the same evidential value as a paper document; the signature identifies its author and expresses their consent, and its reliability is presumed for a qualified electronic signature.

Legal risks

An insufficient power of attorney — overly general powers, poorly described property, unrespected minimum price — exposes the seller to a deed that is unenforceable against them, 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, deception is punishable by five years' imprisonment and a fine of €375,000 (article 313-1 of the French Criminal Code), while forgery and use of forged documents carry three years and a €45,000 fine (article 441-1): this is the reason for signature certification and the identity checks required by notaries.

Usage scenarios: property powers of attorney in practice

Scenario 1: an expatriate owner sells their flat

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 naming their brother as representative, with a minimum price. The owner signs it at the French Consulate General, which certifies their signature, then sends the original to the notary. The file is ready in around three weeks, with no travel required: the savings on travel and accommodation run into 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 certifies their signature. The heirs residing in France sign in person, and one of them represents the Belgian heir. The sale is signed in a single appointment, whereas coordinating travel could have delayed it by several months.

Scenario 3: a family property company sells commercial premises

A property company decides, at a general meeting, to sell commercial premises of 180 m². The manager, hospitalised on the scheduled date, delegates signing authority to a member through a special power of attorney: limited to this property, a minimum price and a six-month deadline, and accompanied by the minutes of the meeting. The notary accepts the file, and the sale takes place within the deadline set out in the preliminary agreement, without any late penalty.

Frequently asked questions

Can a power of attorney under private signature be sufficient?

Yes, for an ordinary property sale: article 1985 of the French Civil Code allows a mandate to be given in writing under private signature, and only the sale itself must be executed by the notary in authentic form. Notaries often ask for the signature to be certified, and some offices prefer a notarised power of attorney. 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 French Civil Code 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 drawn up from abroad?

Three options: sign at the French consulate, which receives the power of attorney or certifies the signature; sign before a local notary, with an apostille or legalisation depending on the country and a sworn translation if necessary; or use the remote notarised power of attorney. This is often the longest step in the process: 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; however, a seller living far away can appear before another notary, connected to the one handling the sale by video conference (article 20 of decree no. 71-941). If they cannot go to any notary, they must grant a power of attorney — and this power of attorney can itself be drawn up remotely, since 2020.

Conclusion

A power of attorney to sell a property is not a mere formality: how it is drafted determines how smoothly the sale proceeds. Article 1985 of the French Civil Code leaves the choice of form open — a power of attorney under private signature is valid for an ordinary sale — but the notary may require a certified signature, and authentic form is required 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 agreements, agency mandates, property company meeting minutes — can be digitalised using an electronic signature compliant with the eIDAS regulation. Certyneo supports real estate professionals, notarial offices and investors with signature tools and an interface designed for multi-signatory documents.
