What is the difference between a preliminary and a final sale contract?

What does a preliminary contract cover?

A preliminary contract, known in Arabic as عقد ابتدائي, is the first written agreement that a buyer and a seller sign for a unit. It records the unit and its location, its area, the total price, the down payment, the instalment schedule and the handover date. It is the document that binds both sides before the property changes hands, and most of the steps that follow are built on it.

Buyers who purchase from a developer meet it at the sales office once the reservation is complete. Read it before you sign, because the figures in it are the ones you will be held to for the rest of the purchase.

What does the final contract add?

The final contract, known as عقد البيع النهائي, is the document that transfers ownership. It is signed once the buyer has paid what the preliminary contract requires, or once the conditions agreed in it have been met. After signing, the contract is registered at the Real Estate Publicity Department (الشهر العقاري). Registration is what makes the sale effective against third parties.

Until the final contract is registered, the buyer holds a right against the seller, not a registered title to the unit. That difference is the reason the second document matters as much as the first.

Why does registration matter?

Registration places the sale on the public record. A buyer whose contract is registered can prove ownership to a bank, a notary or a later buyer. A contract that is never registered leaves its holder exposed if the seller sells the same unit again or pledges it to a lender.

What should I check before signing either contract?

Check the unit code, the area, the price, the instalment dates, the handover date and the penalties for late payment or late delivery. Every one of these must be written in the text, not only in a brochure or a sales message. Confirm that the figures match the reservation form and the sales brochure. If anything differs, ask for it to be corrected in writing before you sign. Keep a signed copy of every page.

Is the preliminary contract enough on its own?

No. A preliminary contract on its own does not transfer ownership. It records the promise and its terms, and the final contract together with its registration completes the sale. A buyer who stops at the preliminary stage depends on the seller's willingness to finish the procedures, and that is why the two documents should be treated as one process.

General guidance — check with the official authority before you act.
