Saving your Proof of Ownership documents
After choosing either a photo or a file to upload, you will have the option to 'save' this. Please select to 'save' your document.
You'll then need to add a second document to verify ownership. You can edit or delete either document as needed by selecting 'edit.'
Once you are happy with both documents, please press the blue button to 'submit documents.' Once you submit this document, you will not be able to change this.
You'll then have the option to go back to your task list to complete any remaining tasks.
