Thank you Nimish,I do not know when the conveyancing of the ff flat commenced , I received a cc email from HMLR Durham 12th Feb 2021,warning the conveyancing solicitor of cancellation (keep in mind I had been completely excluded) the new owner occupied the ff flat July 2020.
The new owner/occupier of the ff flat Ms CC is noted on AV190450 dated 13 July 2020,to be clear,it is this property transfer I am disputing.
During my absence from replying,I have checked how and where I should have been notified,the lease makes reference that Mr GF off the ff flat should have given me notice,he did not as he owed me money,breach of other lease terms etc..But on reading and watching the information video I see that HMLR form AP1 includes reference to leasehold properties and landlord.
Nimish,reading my above query,should I (as landlord) have participated with or been contacted by either of the conveyancing solicitors for the completion of form AP1,I note that the HMLR states that they no longer contact other/third parties.
