You can apply to get the employment history of someone who’s died if you’re legally entitled to claim damages on behalf of their estate:
as part of a claim for personal injury or a fatal accident
under the Diffuse Mesothelioma Payment Scheme
How to apply
Fill in the request employment history about a deceased person form and send it to HMRC. The address is on the form.
If a professional representative (for example a solicitor or coroner) gave you the form, fill it in and return it to them.
