Top 5 Documents Buyers Forget to Prepare (2025)

Why this matters

This guide lists the buyer documents that most often delay an international property deal. For each item you will see why banks and notaries ask for it, which format to bring, usual mistakes, and a quick fix. The language is simple for easy translation.

The Top 5 (ranked by how often they are missing)

1. Source of Funds (SoF) evidence
   What proves it: recent bank statements, payslips, sale contract for an asset (home/car/shares), dividend statements or portfolio reports.
   Quick fix: show the full path: origin → your account → payment (mark the credit that funds your purchase).
2. Proof of address (recent)
   What works: utility bill or bank/credit card statement with your name and address, usually issued within 90 days.
   Quick fix: if not in the deal language, add a certified translation.
3. Certified translations / legalisation (apostille) where required
   Many buyers bring originals but forget the form requested by banks and registrars.
   Quick fix: check if sworn translation or apostille is needed and convert ahead of time.
4. Power of Attorney (for remote signing)
   If you will not attend completion, a short PoA with clear powers avoids rescheduling.
   Quick fix: some countries need notarisation and/or apostille — confirm early.
5. Tax ID / fiscal number + one-line “payment purpose”
   Some banks ask for a foreign TIN/local fiscal ID and a purpose line that matches the SPA.
   Quick fix: request/confirm the TIN early; copy wording from the SPA/reservation.

Comparison at a glance

Use this table to see why each document is needed, which format to bring, and how to fix issues fast.

How to prepare fast (step-by-step)

1. Create one folder with sub-folders: Deal, KYC, SoF, Translations, PoA.
2. Export clean PDFs (no screenshots). If you must scan, use 300 DPI and crop edges.
3. Name files clearly: 2025-08_bank-statement_main-account.pdf, 2025-08_utility-bill_address.pdf.
4. Match names across papers (passport ⇄ SPA ⇄ bank forms). Copy-paste, don’t retype.
5. Check dates: statements and bills should be current; PoA must be valid on completion.

Bonus items buyers forget

• Second ID (driver’s licence or national ID) — some banks ask for two IDs.
• Employer letter or pay slip — quick support for salary as SoF.
• SWIFT MT103 — helps reconcile the incoming transfer.
• Seller’s bank details confirmation — a signed sheet avoids typos.

Common mistakes (and simple fixes)

Scans are blurry or cropped. Fix: rescan at 300 DPI, flat, with margins.

Translations ordered after the bank asks. Fix: order sworn translations together with the SPA/reservation.

SoF only shows the last hop. Fix: include the document that created the funds (salary/sale/dividend) and connect it to your account.

Payment purpose does not match the SPA. Fix: copy the property line (unit/lot) into the payment purpose.

FAQ

How recent should Proof of Address be? Commonly within 90 days; some banks accept 60 or 120 days — bring the most recent you have.

Can phone photos replace PDFs? Usually no. Export proper PDFs or make flat scans at 300 DPI.

Do I always need an apostille? Not always. Some countries need sworn translations only; others need legalisation. Ask before you order.

Is a screenshot of online banking enough for SoF? Bring full PDF statements and the document that created the funds (salary/sale/dividend).

Can one PoA cover everything? Keep it short and specific to this property and completion; broad PoAs often get rejected.

Expert comment

“Most delays come from form, not content. Clean PDFs, clear names, and early translations remove 80% of back-and-forth.”
