The Search Mandate: Everything You Need to Know Before Signing

The search mandate is the contract that binds a buyer to their property hunter. Governed by the Hoguet Law of 1970, it precisely defines the mission entrusted, the fees, the duration and the obligations of each party. It is a legal document that protects you as much as it protects the property hunter, provided you know how to read it. Here is what fourteen years of practice and more than 1,200 mandates have taught me about this document that every buyer should understand before signing.

What a search mandate is, legally

The search mandate is a service contract by which you, the buyer (called “mandant”), entrust a property hunter (the “mandataire”) with the mission of finding a property matching defined criteria. It is neither a commitment to buy nor a guarantee of results. It is a framework agreement that formalises a professional relationship of trust.

The Hoguet Law imposes a strict framework. The mandate must be written: a verbal agreement has no legal value. It must state the identity of the parties, the purpose of the mission, the duration, the amount and terms of payment, the conditions of termination, and the property hunter’s professional card number (carte T). Without these mandatory elements, the mandate is void and the property hunter cannot claim any payment.

This legal framework is your first protection. A property hunter who suggests “starting the search without formalising things” or who delays producing a written contract is sidestepping the law. That is never a good sign.

Exclusive mandate or simple mandate: the choice that changes everything

The exclusive mandate

With an exclusive mandate, you entrust your search to a single property hunter. For the duration of the mandate, you commit not to engage another property hunter for the same search. In return, the property hunter commits to devoting all their energy and resources to your project.

This is the most common format in Paris, and for good reasons. The exclusive mandate creates a virtuous circle: the property hunter knows that if they find your property, they will be paid. This certainty motivates them to invest fully, to activate their off-market network, to dedicate hours of active prospecting, to negotiate relentlessly. A property hunter sharing their mandate with two competitors will mechanically have fewer reasons to go the extra mile, since their time investment may benefit someone else.

The exclusive mandate does not mean you lose control. You can continue to browse listings, flag properties to your property hunter, and have ideas. What changes is that all viewings and all offers go through your property hunter, because they are your sole representative and it is in this capacity that they can negotiate effectively.

The simple mandate

The simple mandate gives you the freedom to search on your own alongside the property hunter, or even to engage several property hunters simultaneously. If you find a property through your own efforts, you owe nothing to the property hunter.

On paper, this flexibility is appealing. In practice, it rarely produces good results. A property hunter on a simple mandate knows they can be undercut at any moment, by you, by another property hunter, or by an agent who contacts you directly. Their level of commitment will be proportional to this uncertainty: lower. They will prioritise their exclusive mandates, where the probability of payment is higher.

The simple mandate can be justified in one specific case: when you are a highly autonomous buyer, you know the Parisian market perfectly well, and you simply want to expand your search area with occasional professional support. For everyone else, which is the vast majority of buyers, the exclusive mandate is the rational choice.

Duration: neither too short nor too long

The standard duration of a search mandate in Paris is between two and four months. This is the window that matches the market reality: an experienced property hunter typically succeeds in an average of 45 days, but some very specific searches (tight budget, unusual criteria, competitive arrondissement) require more time.

A one-month mandate is too short. It does not give the property hunter enough time to prospect seriously, deploy their off-market network, and manage contingencies (property withdrawn from market, seller changes their mind, competing offer). One month is the duration of a trial, not a professional commitment.

A six-month mandate or longer without an exit clause should raise questions. In the Parisian market, a competent property hunter does not need six months to succeed, except for exceptionally complex projects. A long mandate with no possibility of early termination can mean the property hunter is seeking to lock you in rather than to serve you.

The most balanced formula is a three-month mandate, with the possibility of renewal by mutual agreement. This gives the property hunter a reasonable time to succeed, while offering you a natural exit point if the relationship is not working.

Some mandates include tacit renewal: if you do not express your wish not to renew before a given date, the mandate is automatically extended. Read this clause carefully and note the deadline in your diary. Tacit renewal is not problematic in itself, as it prevents an interruption in the search, but you need to be aware of it.

Clauses to check line by line

Search criteria

The mandate must precisely describe what the property hunter is tasked with finding: location (arrondissements, neighbourhoods), property type (flat, minimum surface area, number of rooms), maximum budget, and possibly specific criteria (floor, lift, light, quiet, outdoor space). The more precise these criteria, the better protected you are.

A vague mandate on criteria is an open door to misunderstandings. If your mandate says “flat in Paris, budget 600,000 euros” with no further detail, the property hunter could technically present you with a studio in the 19th as well as a three-bedroom in the 7th. Insist that the criteria faithfully reflect your initial brief.

Good mandates also include a criteria evolution clause: if, during the search, your priorities change (you expand to a neighbouring arrondissement, you increase your budget), the mandate can be modified by written amendment. This flexibility is essential in a market where confrontation with reality often shifts projects.

Fees and payment timing

The mandate must state the exact amount (or exact percentage) of fees including tax, the calculation basis (net seller price or agency price), and the triggering event for payment, meaning the event that creates your obligation to pay.

In a success-based model, the triggering event is generally the signing of the preliminary sales agreement on a property found by the property hunter. Some mandates specify the signing of the final deed (at the notary’s office, two to three months later). The difference is significant in cash-flow terms: check exactly when you will actually need to write the cheque.

For a detailed overview of the different fee models and their implications, our complete guide to fees covers the subject in depth.

The termination clause

How do you exit the mandate if the relationship is not working? The contract must set out the conditions for early termination: with or without cause, with or without notice, with or without penalty. A mandate with no early termination clause binds you for its full duration: this is legal, but constraining.

The most protective mandates for the buyer provide for free termination with a short notice period (15 days to one month), without penalty. Those that impose termination penalties (sometimes one or two months of flat-fee charges) are rarer and should be examined carefully.

The follow-on clause

This is the least known and most important clause to understand. The follow-on clause (or “recall” clause) provides that if you buy a property that was presented to you by the property hunter during the mandate, but you complete the transaction after the mandate has ended, you still owe the fees.

The duration of this clause varies: six months, one year, sometimes two years after the end of the mandate. It is legitimate in principle: it protects the property hunter against a buyer who would wait for the mandate to end to buy alone a property identified by the property hunter, thus avoiding the fees. But its duration must remain reasonable. Beyond twelve months, the clause becomes excessive.

Also check its scope: does it apply only to properties actually visited with the property hunter, or to all properties whose address was communicated by the property hunter, even without a viewing? The first interpretation is reasonable; the second is abusive.

Jean Mascla’s advice: Read the mandate in its entirety before signing. This sounds obvious, but the majority of buyers I meet admit not having read their previous property professional’s mandate to the end. A well-drafted mandate is three to five pages long: that is ten minutes of reading that can save you months of complications.

The right of withdrawal: your safety net

The Consumer Code grants you a 14-day withdrawal period after signing a search mandate, when it is signed outside the professional’s premises (which includes signing at your home, in a cafe, or remotely by post or email).

During these fourteen days, you can cancel the mandate at no cost, without justification, and without penalty. The property hunter is required to inform you of this right in writing, typically via a detachable withdrawal form appended to the mandate. If this information is not included in the contract, the withdrawal period is extended by twelve months.

This right is absolute and cannot be removed by any contractual clause. If a property hunter tells you “the right of withdrawal does not apply in our case”, they are wrong, or they are lying.

However, if the property hunter begins the search during the withdrawal period with your explicit consent, and finds a property during this period, the situation becomes more complex. The law provides that you can still withdraw, but the professional may request compensation proportional to the work carried out. In practice, this situation is rare: most serious property hunters do not start intensive searching until after the withdrawal period has expired, precisely to avoid these complications.

Why the exclusive mandate is in your interest

I return to this point because it generates the greatest hesitation among buyers. The idea of “not putting all your eggs in one basket” is intuitively reassuring. But in property, it is counter-productive.

The Parisian market operates at speed. A correctly priced property in a sought-after arrondissement sells in days, sometimes in hours. In this context, the property hunter’s reactivity is decisive. A property hunter on an exclusive mandate knows that every minute invested in your search will be rewarded in case of success. They pick up the phone at the first alert, view the property within the hour, send you a report immediately, and formulate an offer before the competition wakes up.

A property hunter on a simple mandate, however, calculates. They know you may also be searching on your own, that you may have engaged a competitor. Before mobilising on a property, they wonder whether they are about to invest three hours of work for nothing. This hesitation, even unconscious, slows the process, and in the Parisian market, a day’s delay can cost you a flat.

Exclusivity also creates a dynamic of trust that improves the quality of advice. A property hunter to whom you give full trust will speak with total frankness: “this property is not for you”, “your budget does not allow this neighbourhood”, “this co-ownership has a problem”. A property hunter competing with others will tend to soften their words to avoid putting you off.

Our mandate is clear, transparent, and 100% success-based: you only pay if we find your property. No deposit, no upfront financial commitment, and a 14-day right of withdrawal. That is the foundation of trust.

The most common mistakes when signing

After more than 1,200 mandates, I have identified the mistakes buyers make most often when formalising their search.

The first is signing too quickly. The enthusiasm of the first meeting, the desire to launch the search as soon as possible, the subtle pressure of a skilled salesperson: everything pushes you to sign on the same day. Take the mandate home, read it at your leisure, ask your questions by email. A serious property hunter not only accepts this delay but encourages it.

The second is not putting your criteria in writing. The verbal brief from the first meeting is essential, but it must be reflected in the mandate. If you said “absolutely no ground floor” but the mandate does not mention this constraint, it does not exist legally.

The third is ignoring the follow-on clause. Many buyers only discover this clause after the mandate has ended, when they decide to buy a property viewed during the search period. The surprise is unpleasant and disputes are frequent. Read it, understand it, and if it seems excessive to you, negotiate it before signing.

Jean Mascla’s advice: The search mandate is the only moment in the process where you have real negotiating power with your property hunter. Once signed, the dynamic changes: the property hunter works, you wait. Use this moment to ask all your questions, obtain all clarifications, and ensure the document reflects exactly what you understood during the first meeting.

The mandate as the foundation of the relationship

I have deliberately approached the search mandate from a legal and practical angle, because it is a contract before it is a symbol. But beyond the legal aspects, the mandate is the founding moment of the relationship between a buyer and their property hunter.

A well-constructed mandate creates a clear framework in which both parties know exactly what is expected. The property hunter knows your criteria, your budget, your timeline. You know their fees, their method, their commitments. There is no grey area, no ambiguity, no “we’ll see how it goes”. This clarity is the necessary condition for an effective search.

At Home Select, we consider the mandate to be the conclusion of the first meeting, not its starting point. The first conversation serves to understand your project in depth, to calibrate realistic criteria together, and to check that the chemistry works. The mandate formalises what has already been discussed and validated. That is why we never ask for a signature on the same day: we send the contract by email, we allow time for reflection, and we answer every question.

When you understand what you are signing, when the property hunter understands what you are looking for, and when both parties are aligned on the rules of the game, the search can begin in the best possible conditions. And that is precisely what we will explore in the detailed account of a typical search with a property hunter.
