10 years NI proof and P60

[mkh05r]

Hi, I need advice on my wifes AN application on 3 year route.( I have got citizenship already).
She worked on and off part time for several employers on very low income for the last ~8 years. my queries:
1. The issue is we donot have accurate work history but can guess on the months she worked and we donot have any P60s. Is this alright not to submit any P60s/Payslips and only write the estimated history. HO should be able to get these info from their own sources right ?
2. Then do we really need to submit the HMRC NI/Employment history as some on this forum suggest we can request online. Also a few members reported their P60s were not accepted by NCS instead they copied the PAYE ref.

Thanks for your time

It is your responsibility to provide accurate information, the HO won't do this for you. Get an employment history/NI contribution history from HMRC and submit it with the application.
