I just moved to Spain not long ago and was recently asked to provide a proof of bank transfer for some paperwork, which left me completely stumped. I used to think a simple transaction screenshot was enough, but things are more formal here. After doing some research, I’ve finally figured it out and wanted to share what I learned with anyone facing the same confusion.
Essentially, this document is an official transaction record from your bank, usually in PDF format. It’s much more formal than a regular screenshot and is required in many situations, such as:
- Proving to your landlord that you’ve paid the rent
- As proof of financial transactions for residency renewal, like when [transferring money from Spain to the US]
- As evidence in case of a transfer dispute with a merchant or a friend
- Showing your school that you’ve paid your tuition fees
Basically, whenever you need to formally prove that you have ‘actually sent the money,’ you’ll need this document.
How to Get a Proof of Transfer?
It’s actually quite simple to get one, mainly through your bank’s mobile app or online banking, which is also useful for things like [transferring money from Spain to Canada]. I primarily use CaixaBank and BBVA, so I’ll use them as examples, but the process is very similar for other banks.
1. CaixaBank Now
I find CaixaBank’s app to be the most convenient. After logging in, find the specific transfer record you need and tap on it. On the transaction details page, you’ll see a ‘Share’ icon or a button labeled ‘Comprobante’ in the top right corner. Tapping it will automatically generate a formal PDF document that you can save to your phone or share via WhatsApp, email, etc. The whole process takes less than a minute and is incredibly smooth.

2. BBVA
Finding this feature in the BBVA app can be a bit tricky; I personally prefer using the web version. After logging into your online banking, go to your account and find the relevant transfer record. Click on the transaction to expand its details, which might also be useful for other operations like general [money transfers in Spain]. Look carefully on the details page for an option like ‘Ver justificante,’ ‘Descargar comprobante,’ or something similar. Clicking it will also generate a PDF receipt for you to download. The table below summarizes the key terms for common banks:
| Bank | Common Feature Name | Notes |
| CaixaBank | Comprobante / Compartir | Very prominent in the app |
| BBVA | Ver justificante / Descargar | Easier to find on the website |
| Santander | Justificante de la operación | Usually on the transaction details page |
So, this ‘proof of transfer’ is simply an official transaction receipt. It’s a good habit to save a copy immediately after making important payments, just in case. This is especially true for large amounts like rent or tuition fees—always save your proof of payment! Have you used other banks? Is it easy to get the receipt?
