Forms for Transfer Land Registry

[Sammy986]

Good evening,

I've been granted probate for my fathers estate which comprises of a flat which has no mortgage. The flat is part of a housing association council estate and is leasehold owned.

Is the process different considering its a leashold flat?

Would I need to fill any out any forms other than the below.
AP1
AS1
ID1

Also regarding the type of application, would the correct category be transfer or assent?

Thank you for your time.
