A single, written introduction
between two private parties.

The introduction.

PocketLister has carried a written question from the Buyer to the Seller and a written reply from the Seller back to the Buyer. The Seller has chosen to release direct contact details, and the Buyer has paid the €99 unlock fee. PocketLister’s role as introducer is complete on signature of this agreement.

Off-market window.

This agreement applies for one (1) month from the date of signature, between this specific Buyer and this specific property. If a sale completes between the Seller and the Buyer (or any entity reasonably connected to the Buyer, such as a spouse, child, or controlled company) within this window, PocketLister is entitled to its fee under clause 04. After one month, the agreement expires and no further obligation exists between the parties under this document. The Seller is free to list the property publicly elsewhere from that point forward.

What PocketLister provides.

From signature through to the day of completion, PocketLister provides the Seller and the Buyer with the following:

• AI-drafted reservation contract (contrato de reserva)
• AI-drafted arras contract (contrato de arras penitenciales)
• Buyer KYC and source-of-funds packet
• NIE application guidance (where applicable)
• An always-on AI deal copilot for both sides, throughout
• Document translation between Spanish and the parties’ languages
• Direct access to PocketLister’s outside legal counsel for escalations
• The Brief produced for this introduction (Seller keeps a copy at a portable URL)

The Seller and the Buyer remain the principals in the transaction. They sign their own contracts, attend their own notary appointment, and receive or transfer funds personally. PocketLister does not act as agent, escrow agent, or notary.

PocketLister’s fee.

The fee is calculated on the price recorded in the public escritura at the Registro de la Propiedad. PocketLister invoices the Seller within 14 days of escritura. Payment is due within 14 days of invoice.

Confirmation of completion.

The Seller agrees that PocketLister may, at its sole expense, monitor the public Registro de la Propiedad for the registration of a transfer of the subject property to the Buyer or any reasonably connected entity. The Seller also agrees to confirm the completion of the sale to PocketLister in writing within seven days of escritura, including the final price.

Privacy.

PocketLister will not list the property publicly, share the Buyer’s or Seller’s details with any third party, or record any aspect of this match on a portal or shared database. All communications between the parties facilitated by PocketLister are held confidentially and never used to market either side to any third party.

Off-market guarantee — the only refund condition.

The Buyer pays the €99 only after reviewing the brief and choosing to open the introduction — nobody pays to unlock a home they don’t already find compelling enough on the brief alone. The unlock fee buys one thing: a private introduction to a privately held home.

Accordingly, the €99 is refunded automatically and in full, with no application required, if — at any point during the one-month window — PocketLister’s independent off-market verification finds that the subject property was, in fact, publicly listed for sale on a property portal or with another agency at the time of this introduction. The private introduction had no consideration; the fee is returned.

This is the sole refund trigger for the unlock fee. Refund is independent of clauses 04 and 08, and does not extinguish the parties’ obligations if a sale subsequently proceeds.

Off-market representation — breach & liquidated damages.

The Seller expressly represents and warrants that, at the moment this introduction is opened to the Buyer, the subject property is not publicly listed for sale on any property portal (including but not limited to Idealista, Fotocasa, Kyero, Rightmove, James Edition, Engel & Völkers, Lucas Fox, Drumelia, Marbella Estates, the Seller’s own website or any other agency’s website) and is not being actively marketed by any third-party agent in any form — print, social, brochure, networked database or otherwise.

PocketLister carries out an independent off-market verification check before each introduction and repeats it on a rolling cadence throughout the one-month window. The mechanics and evidence retained are described in clause 08bis below.

The Seller acknowledges that this 2% is a fair pre-estimate of the loss PocketLister suffers when the off-market representation that founded the introduction turns out to be untrue, including the work performed on the Buyer’s behalf, the brand promise PocketLister makes to its buyer-side mandates, and the cost of carrying out the verification check itself.

Verification mechanics & the evidence packet.

The off-market verification check is performed automatically by PocketLister’s system at three points in time: (i) when the Seller opens a Quiet Profile, (ii) at the moment this introduction is opened to the Buyer, and (iii) on a rolling cadence (no less than weekly) throughout the one-month window. For each check, PocketLister captures and retains the following Evidence Packet in tamper-evident form:

1. Portal HTTP capture — the raw HTML response from every portal queried, with timestamp, request URL, response status, and full response headers, retained in PocketLister’s evidence store.
2. Full-page rendered screenshot — captured by a headless browser at 1440×900, including any agency branding, asking price, photos, and Catastro reference.
3. Perceptual photo-hash match — PocketLister computes a 64-bit perceptual hash (dHash) for each photo the Seller uploads to their Quiet Profile and for each photo on any candidate portal listing. A match at Hamming distance ≤ 6 is treated as the same image. The hash table is recorded and reproducible.
4. Catastro / address fuzzy match — the Catastro reference, urbanization name, calle/street, and postcode are tokenised and matched against the portal listing’s address fields. A confidence score is recorded.
5. Independent third-party archive — PocketLister submits the matching portal URL to the Internet Archive’s Wayback Machine (web.archive.org/save/) at the moment of capture. The returned snapshot URL and timestamp are stored. This snapshot is held by a neutral third party and is independently verifiable by the Seller.
6. Cryptographic timestamp — the SHA-256 hash of the entire Evidence Packet is submitted to a public OpenTimestamps server and anchored to the Bitcoin blockchain. The resulting proof file is stored alongside the packet and proves that the evidence existed at or before the timestamp, without trusting PocketLister.

If a breach is identified, PocketLister delivers a Breach Notice to the Seller in writing within seven days, containing: the Evidence Packet (1)–(6) above, the matched portal URL(s), the perceptual-hash comparison report (Seller’s photo vs portal photo, side-by-side), the Wayback Machine snapshot URL, the OpenTimestamps proof file, and PocketLister’s computed liquidated-damages figure under clause 08.

The Seller has fourteen days from receipt of the Breach Notice to provide a written explanation if the Seller believes the match is mistaken (for example, a previous listing taken down before the introduction, an unauthorised duplicate by a third-party agent, or a portal data error). PocketLister will review any such explanation in good faith and, where the Seller’s account is corroborated, will withdraw the Breach Notice and process no refund to the Buyer.

The parties agree that the Evidence Packet, taken as a whole — in particular the combination of (i) a perceptual photo-hash match, (ii) an independent Wayback Machine snapshot, and (iii) a blockchain-anchored timestamp — constitutes sufficient evidence of public listing for the purposes of clauses 07 and 08, and is admissible in Spanish courts under Spanish civil-procedure rules on electronic evidence (LEC art. 299.2 and Real Decreto-ley 14/2019). The full verification protocol and the Seller’s rights to respond are published at pocketlister.ai/off-market-verification and form part of this agreement.

Governing law.

This agreement is governed by Spanish law and the parties agree to submit any dispute to the courts of Marbella. Where a dispute concerns unpaid fees under clause 04 or clause 08, PocketLister reserves the right to seek recovery via proceso monitorio, supported by the public escritura record, the off-market verification record retained by PocketLister, and this signed agreement.
