Registration Guide


You’ll need to complete our Registration Process in both of these scenarios:

1. You want to register for bidding on a property that is being sold via auction

2. You want to ‘reserve’ (formalise) your purchase once the vendor has accepted your offer for a property 


Both the vendor and BidX1 are obliged by the Laws on the Prevention of Money Laundering and Terrorist Financing – the documentation we ask you to provide is to comply with these regulations. 

Step 1

You can register to bid on a property from the property listing page – simply click the blue ‘Register to Bid’ button to start the process. 

First, you’ll need to log in to your BidX1 account. If you don’t have an account yet, it’s easy to create one – all you need is an email address and a password.  

Don’t forget that your password must be at least 10 characters long (with no spaces) and include: 

  • A Lower Case Letter 
  • A Capital Letter 
  • A Number 
  • A ‘special’ character (e.g. ! ? & % #) 
Step 2

Fill out your details – and then click ‘Next’

  • Name
  • Address
  • Phone number
  • Nationality
  • Date of birth
Step 3

Upload your documents. You will need: 

  • Proof of Identity – a photo of your DNI card (front side) OR your Passport (photo page) 

  • Proof of Address – a photo of a Utility Bill showing your address OR your DNI card (back side) OR your NIE (back side)

  • Selfie – A photo of yourself so we can verify your identity against your ID  

Step 4

If you are purchasing the property with someone else, you can list any additional purchasers at this point – they'll receive a notification asking them to verify their details.   
As required by law, you’ll also need to let us know who is providing the deposit, as well as some basic information about your occupation and reason for purchase (main residence, investment property etc.).  

Step 5

Review your details to ensure that everything is complete and correct.  


Step 6

Read and accept the Terms & Conditions.

We advise you to check that you have read and understood all the various legal documents and Terms & Conditions prior to bidding in an auction or ‘reserving’ a property.  

Step 7

You’re almost there! Pay your deposit by card or bank transfer. 

If you’re taking part in an auction, the deposit is fully refundable if you are not the winning bidder. If you are the winning bidder, the deposit will go towards the total sale price. 

If you’re ‘reserving’ a property, this deposit will go towards the agreed sale price. 

Step 8

As soon as you’ve paid the deposit, our team will get to work reviewing your registration. Once you’ve been approved, you’ll receive an email to confirm that you’re ready to go.

If you’re ‘reserving’ a property with a pre-agreed acceptance price, all you need to do is place an offer at that acceptance price on the property listing page once your registration has been approved.

If the property is being offered via auction, you can try bidding before the auction using our Bidding Demo.  

Registering as a company? 

If you are purchasing a property on behalf of a company, you will need to provide documents including the Proof of Incorporation, Declaration of Ownership Structure, and Management Structure. 

The Managing Director(s) will be required to confirm their details, along with any beneficial owners who own 25% or more of the company.
