Hi, thanks for your reply. I am not planning to use an agency hence wanting to know what steps to take when she provides me with her documents. I will need to independently verify that the documents are valid/reflect her true status, so the recommendation to check the NI number with HMRC is really useful.
I do have one more question, as I am an individual and not a company, would I still be able to use a third party company such as Experian's services or would this service be offered to companies only?
Thanks for your help
