transfer deeds to beneficiary - which forms?

I am executor of my father's will and I am also the beneficiary.  Can you confirm that I need to fill out 

AP1
AS1 or TR1 (not sure which here)
ID3

and send a copy of the probate letter and the stamp duty letter and bizarrely a postal order?

Can the land registry look at the system used by the National Inst for Health and Care Research for a good portal to upload documents and verify an application and the local councils to provide a pay online solution.

Many thanks
Anna

Anna - if it's executor transferring to beneficiary then forms AP1 (application form) and AS1 (Assent) you need. Plus ID verification using forms ID1/conveyancer or ID3/others.
Certified copy of probate also
Fee payable by cheque or postal order. 
We are looking at ways to enable people to pay the registration fees online

I need to send a completed AS1 form to change deceased fathers property to us (beneficiaries), what else do we need to send, how much do we send and where do we send it to.  We can't seem to get a direct answer from all the links, from CAB etc, it's so frustrating, thank you

Linda - you need forms AP1, AS1 and ID1/ID3 as appropriate - HMLR Guide Page  · HM Land Registry
The fee is payable under Scale 2 (postal) on the current market value of the property - HM Land Registry: Registration Services fees - GOV.UK
The standard postal address is linked to from the form AP1 - HM Land Registry address for applications - GOV.UK
