Submitting evidence of public funds/state benefitsa

[nmc88]

Hi all,

My sister is currently in the process of applying for her PR (she is Portuguese) she claims some benefits due to her situation but also works and has been for over 10 years!

She claims housing benefit, disability allowance, working tax credit. When completing her form it stays she needs to submit evidence of this, it’s just not clear how far back she needs to go, or exactly what or how much evidence is needed in this instance.

Can anyone who has submitted evidence of benefits claimed with heir application please advise?

Thanks
