Hello Debbie - a form AS1 is used to transfer (assent) a property where the executors are transferring to the beneficiaries. Form AP1 is the application form and form ID1 is the identity verification for each party.
Form ID3 can be used by others as listed in PG 67 to verify identities as appropriate -

It's unclear from your post whether you are transferring the legal ownership to you and your brother or your brother and Father and apologies if it's just my poor understanding
If you are transferring into joint names then the legal ownership does not automatically transfer at the 'end of the trust'. The register can be updated re a death and the legal ownership then passes to the surviving joint owner to deal with. But how the trust is then wound up/ended and what happens to any beneficial shares would be something to seek legal advice on
I appreciate that you have ploughed through our guidance already but the key Q and A you need to consider is how best to protect your Father's lifetime interest trust and what options exist re how you update the register re the name(s) of the new legal owners as appropriate. You do have options and it's worth ensuring that you all are aware of what those are and what's 'best' and how future events then impact also
For that reason our online assisted guidance covers the various registration options once you have decided which one is 'best' as we are not privy to or involved in the decision-making process you have one through -
