Introduction
In Paris 14, selling or buying a property is both an exciting and engaging project. However, for many buyers and sellers, going through the "sales promise" or the "sales compromise" raises many questions. These two preliminary contracts, often confused, are indeed different, both in their scope and in their consequences for the parties. At Guy Hoquet Paris 14 Plaisance Pernety, we make pedagogy and listening the key to personalized support, to secure every step of your transaction. Discover here the essential distinctions, the conditions to prioritize according to your situation, and our tips for choosing the option best suited to your project.
Sales promise or compromise: definitions and legal scope
The "sales promise" (or unilateral promise of sale) engages the seller to reserve the property for the buyer, who benefits from an option period—generally ten days—to confirm their purchase. During this period, the seller cannot sell to another, but the buyer can withdraw, potentially losing a deposit.
The "sales compromise" (or synallagmatic promise) engages both the buyer and the seller upon signing: each is obliged to complete the sale, except in cases of application of suspensive clauses. It is a true sales contract, which will conclude with the authentic deed at the notary. This difference in commitment is a central point to guide your choice, depending on your situation and your security expectations.

Duration of the sales compromise and promise: what you need to know
The duration of the sales compromise is usually set between two and three months, the time needed to lift suspensive conditions (obtaining a loan, purging the right of preemption, etc.). This duration can be adapted according to the complexity of the file or specific needs of the buyer and seller. As for the sales promise, the option period is often shorter (ten to fifteen days for lifting the option), but the final signature can also occur within two to three months.
It is important to clearly frame these deadlines in the preliminary contract to avoid any source of tension or blockage. Expert support and rigorous follow-up, like the approach of Guy Hoquet Paris 14 Plaisance Pernety, ensure compliance with deadlines and anticipate potential difficulties. Find our tips on the secure sales process in Paris 14.
Property diagnostics and validity: a key step before the preliminary contract
Whether it is a promise or a compromise, the technical diagnostics file (DDT) must be provided at the time of signing the document. The law imposes a specific validity duration for each diagnostic (asbestos, lead, DPE, electricity, gas, ERP, etc.), under penalty of seeing the transaction called into question.
In 2026, the regulations on the validity period of property diagnostics remain a point of vigilance for selling owners. Being supported by a reference agency guarantees the compliance of the file and peace of mind for both buyers and sellers. Discover our practical tips on up-to-date diagnostics before sale.

Compromise or promise: what choice according to your real estate project?
The choice between promise and compromise mainly depends on your profile and expectations:
- You are a seller in Paris 14: the unilateral promise can secure you if you want to offer the buyer a hesitation period while blocking the property. Conversely, the compromise directly engages both parties, which can reassure if you already have a solid offer.
- You are buying your primary residence: the compromise offers a more balanced framework, where the suspensive conditions genuinely protect both the buyer and the seller.
- You are investing in Paris 14: to optimize your portfolio, the speed and security of the compromise are often prioritized, especially if you want to close several operations within short deadlines.
