I haven’t been in refuge, but I had legal aid through a solicitor. I had to fill in a means tested application form with her and provide evidence of criminal proceedings (so an email from the Police Officer to the solicitor giving my ex’s details, crime number and bail conditions).
hope you are ok and feeling supported in Refuge. personally, i wouldn’t say it guarantees anything, because not only is legal aid dependent upon evidence of DV (which Refuge worker could provide), but also financials, and i’ve still had to provide police evidence, etc. for things despite being in Refuge.
Best advice would be to ask your keyworker i think? good luck with everything
