Official Source Revalidation — Preliminary Sale Contract

Start with the exact document, not its marketing label

“Preliminary contract” is a commercial label that can describe very different instruments. One file may contain a simple private reservation or promise, another a notarised real-estate sale promise capable of annotation in the land register, and another a pre-paid housing consumer contract subject to special legislation. Official-source revalidation begins by reading the actual document and identifying its legal function, parties, property, obligations and form. Do not conclude that a document is a valid sale promise because its English title says “preliminary sales agreement,” or that every developer contract follows the same statutory regime.

Recheck the formal rule against TKGM material

The Tapu Sicili Tüzüğü states that annotation of a real-estate sale promise as a personal right requires a contract arranged by a notary. TKGM also publishes a transaction sheet for sale-promise annotation describing the notarised contract and other documents used in the registry process. When a deal depends on an annotation, verify the current TKGM rule rather than relying on a broker template or an old legal summary. Confirm whether the contract in hand was actually arranged in the required form and whether the proposed annotation concerns the same registered property.

Separate validity, enforceability and registry effect

Three questions must not be collapsed. First: is the contract valid in its own legal category? Second: what obligations can be enforced between the parties? Third: can a personal right arising from it be annotated in the land register, and has that annotation actually occurred? A signed private paper may carry some contractual evidence without creating the registry protection associated with a properly annotated notarised promise. Conversely, the existence of a notation does not excuse checking whether the underlying property, parties and conditions still correspond to the intended transaction.

Check whether consumer pre-paid housing rules apply

Where a consumer buys housing before delivery and the transaction falls within Türkiye’s pre-paid housing regime, Ministry of Trade guidance and Law No. 6502 introduce specific protections, including pre-contract information and formal requirements. Those rules should be applied only when the transaction fits the statutory scope. Do not copy consumer-law conclusions into a land purchase, commercial property acquisition or another agreement outside that regime. Revalidation should record why the regime is applicable, not simply cite it because the seller is a developer.

Verify property identity and seller capacity anew

Official legal form cannot rescue a contract that points to the wrong property or an unauthorised seller. Reconcile province, district, neighbourhood, ada/parsel, independent-unit information where available, and the registered owner. If the project used provisional unit numbering, preserve the bridge to the registered identity. Confirm whether the seller is the registered owner or has authority to undertake the promised transaction. If a corporate seller, power of attorney or representative is involved, verify current authority rather than assuming the authority that existed when the draft was prepared remains valid.

Revalidate dates, conditions and later amendments

A preliminary contract may be legally significant for years, but facts around it can change. Recheck signing date, performance deadline, payment schedule, cancellation rights, delivery conditions, any annotation date and later amendments. TKGM historical guidance on sale-promise annotations also illustrates why dates matter in registry administration. If an amendment changes the property, price, parties or performance route, confirm that the formal and registry position remains coherent. Do not attach a new commercial addendum to an old legal instrument and assume the complete package still has the same effect.

Tie source revalidation to payment decisions

Before a non-refundable instalment is released, the legal team or transaction reviewer should state which official rule was checked, when it was checked, and what conclusion it supports. If the purchase depends on a notarised sale promise or registry annotation that has not occurred, that missing step should remain an open condition rather than being disguised by a generic “contract signed” status. Payment control should distinguish between a document that evidences commercial agreement and a document that provides the legal protection the payment policy actually requires.

Keep a source note that a later reviewer can reproduce

For each legal conclusion, record the official source, page or article when practical, access/check date and the proposition supported. For example, the TKGM registry regulation supports the form of documents required for annotation; Ministry of Trade guidance supports consumer pre-paid housing requirements where applicable. Avoid source lists that merely accumulate links. A source is useful only if a reviewer can connect it to the specific statement in the article and to the exact transaction question.

When to reopen revalidation

Reopen the review after a significant legislative or administrative update, a change in buyer or seller, replacement of the property, a new amendment, a long delay, a dispute over refund or performance, or before closing if the contract is still being relied on. Revalidation is not a one-time legal opinion. Its purpose is to ensure that the document’s legal description, official basis and actual transaction facts still match at the moment a decision or payment is made.

Decision standard

The record is complete only when the reviewer can state what type of preliminary instrument exists, which official rule governs the relevant effect, whether required form has been met, whether property and parties match current registry facts, and what unresolved conditions remain. If one of those elements is uncertain, describe the uncertainty directly. A precise “not yet verified” is safer than upgrading a commercial document into a legal protection it may not provide.

Frequently asked questions

How can assignment to another buyer change the true cost of preliminary property sale promise?

A preliminary property sale promise creates contractual rights but should not automatically be treated as a completed title transfer. Ministry of Justice materials explain the notarial role and possible title-registry annotation, while TKGM materials distinguish the promise/annotation from final registration of ownership. Do not treat a months-old saved document as final evidence. Reopen the relevant MERSIS/TKGM or Ministry of Justice source, record the access date and determine whether the information changed. For dynamic authority and registry data, source freshness is part of accuracy. For this exact point—“assignment to another buyer” within preliminary property sale promise—use the cited source to establish the governing rule for the same property and current transaction.

Is every written developer agreement a registrable sale promise?

No. The legal instrument and form must be identified. Registry annotation of a sale promise has formal requirements; the commercial title of a document is not enough.

Which fee, tax, delay or correction cost can arise in preliminary property sale promise, specifically assignment to another buyer?

Do not treat a months-old saved document as final evidence. Reopen the relevant MERSIS/TKGM or Ministry of Justice source, record the access date and determine whether the information changed. For dynamic authority and registry data, source freshness is part of accuracy. Recheck current Ministry of Justice legislation/guidance and TKGM materials when the contract or transaction structure changes, especially form, annotation or parties. For the document check on “assignment to another buyer” within preliminary property sale promise, match the official identifiers, date, authority and scope to the closing file; a related document for another unit or older version is not enough.

Do pre-paid housing consumer rules apply to every off-plan project?

Not automatically. Confirm that the specific transaction falls within the statutory consumer pre-paid housing scope before applying those rules.

Should the cost be priced before signing or after closing in preliminary property sale promise, specifically assignment to another buyer?

Recheck current Ministry of Justice legislation/guidance and TKGM materials when the contract or transaction structure changes, especially form, annotation or parties. For the risk question on “assignment to another buyer” within preliminary property sale promise, treat any unresolved mismatch as a live transaction issue until the competent record or authority shows the required status.

When should a preliminary contract be revalidated?

After material amendments, party/property changes, long delay, relevant official updates, and before a payment that depends on the contract’s legal effect.
