Buying off-plan in Prague: the risks and the protections

Buying a flat from a drawing means paying for a place that cannot yet be seen, lived in or sold. The reward is a choice of layout, a new building and, often, a price agreed early. The price of that reward is risk: the building may be late, the specification may drift and, in the worst case, the developer may fail with your money in the project.

Czech law offers less to the off-plan buyer than some other countries do, and it is better to know that at the start. This explainer sets out the risks, the protections that exist, and the clauses to negotiate. It is general information, not a legal opinion on any contract.

What the law does and does not give you

The central point is a negative one. No Czech statute ring-fences the advance payments of buyers of flats under construction, unlike the guarantee fund some other countries operate (as of October 2026; no bill confirmed; check the Ministry for Regional Development). Protection comes from the general rules of the Civil Code (zákon č. 89/2012 Sb.) and from what you agree in the contract.

That does not leave the buyer with nothing. The Civil Code gives consumers protection against unfair terms in standard contracts, requires clarity and sets rules on defects. A developer is a business and a private buyer is a consumer, so consumer provisions can apply. The Czech Trade Inspection Authority (ČOI) offers out-of-court help in consumer disputes. But these rules apply after something has gone wrong, and none of them guarantees that the flat will be finished.

The legal route to ownership

Developers commonly use a two-step contract. First comes a reservation agreement, which holds the flat for a period against a deposit. Then comes a contract on a future purchase contract (smlouva o smlouvě budoucí kupní), in which the parties promise to conclude the final sale once the building is finished and the units are legally created. Payments are made in stages under this contract. When the building is complete and the declaration creating the units has been registered, the final purchase contract is signed, and ownership passes on registration in the cadastre, which cannot happen before a 20-day protective period (as of 2026; check the ČÚZK). Our guide to how developer sales work shows the sequence.

The practical consequence is that, until the final contract and registration, you are not the owner of anything. You hold a contractual claim against the developer. If the developer becomes insolvent, a buyer with only a contractual claim is generally one creditor among others. This is why where your money sits matters so much.

The main risks

Delay. Permits, supply problems or finance can push completion back. Our article on why housing in Prague is slow to build explains the causes.

Insolvency. If the developer or the project company fails, advance payments may be hard to recover. Checks of the seller's finances are in the guide to judging a developer.

Change of specification. Materials, layouts and common areas can differ from the brochure. The contract's technical specification is what binds, not the visualisation.

Price creep. Additions, changes and extras can raise the cost, as our piece on hidden costs shows.

Area differences. The final measured area can differ from the planned area, and a price adjustment clause decides who bears it.

Defects. Faults appear after handover. Rules on remedies are in the section below.

The protections you can negotiate

Because the law sets a floor and the contract sets the rest, the clauses matter. Read them in roughly this order.

1. Where the money goes. Escrow with a notary, lawyer or bank, with release tied to verifiable stages, is a stronger position than paying the developer directly. Our explainer on reservation agreements and escrow describes the options, and the one on payment schedules shows how stages are set.
2. Who certifies the stages. A stage should be confirmed by an independent party, such as a construction supervisor, not by the developer alone.
3. A completion date and a penalty for delay. A contractual penalty (smluvní pokuta) per day of delay gives the clause teeth. Check how it is capped.
4. A right to withdraw. The contract should say when you may withdraw (long delay, a major change in the specification) and what is refunded, with what interest, and by when.
5. The specification. A technical annex listing materials, finishes, appliances and areas.
6. The bank's lien. If the land is mortgaged to the developer's bank, the contract should say how the lien will be released for your flat and what you get if it is not.
7. A price adjustment mechanism for area differences, with a measurement method.
8. Handover procedure. A written protocol for defects and the deadline for fixing them, as described in what to check at handover.

Defects after handover

The Civil Code separates statutory liability for defects from a contractual guarantee. For a purchase of real estate, a hidden defect must be raised without undue delay and at the latest within five years of taking over (§ 2129). Where a building is delivered under a contract for work, the same five-year limit applies (§ 2629); an implementing regulation may shorten it to two years for some parts, and an agreed shortening is ignored if the client is the weaker party. The Civil Code's consumer presumption that a recent defect existed at takeover (§ 2161) concerns movable goods, so do not count on it for a flat (check with a lawyer). Contractual guarantees, often longer on the structure and shorter on equipment, are voluntary. Our article on what builders and developers owe you gives the detail.

The 24-month consumer guarantee for goods does not apply to the flat itself. It matters for items sold separately, such as appliances.

The role of a lawyer

For an off-plan purchase, a lawyer's review of the contract is cheaper than any of the risks above. Ask for the developer's draft early, and ask the lawyer to look at the payment mechanism, the withdrawal clause and the penalty. Our guide to notaries, lawyers and escrow explains who does what, and a mortgage lender will want its own conditions met, so talk to the bank early (see the application guide).

Frequently asked questions

Are my payments to a developer protected by law in Czechia?

No dedicated statute ring-fences them (as of October 2026). Protection comes from the Civil Code and the contract, so use escrow or staged release.

Am I the owner while the building is under construction?

No. You hold a contractual claim. Ownership passes on registration in the cadastre after the final contract.

How long can I claim for defects?

For real estate, hidden defects must be raised within five years of takeover under the Civil Code. A contractual guarantee is separate and voluntary.

What if the developer is late?

The contract decides. Look for a completion date, a daily penalty and a right to withdraw with a refund.

Do I need a lawyer?

It is advisable. The contract is the main protection, and a lawyer can check the payment, withdrawal and lien clauses.

A practical next step

Send the developer's draft contract to a lawyer with three questions: where does my money sit, when can I withdraw and get it back, and what happens if the developer's bank enforces its lien? Do not pay the first instalment until you have the answers in writing.
