Adverse possession with land registry

technonono

Hi

I wonder if anyone can give me some guidance on a case currently with land registry where status says application pending/awaiting attention. It is a complex case involving adverse possession. New application gone in almost 2 years ago. Status is 'awaiting attention' on land registry website. Person making application in 80s, anxious to sort this out and has submitted letters from themselves and family and solicitor asking for this to be dealt with asap. Solicitor must have been asked for more info by land registry as solicitor contacted applicant for more info in last few months. Will the letters help, is there anything else that can be done, would anyone have any idea how long this might take? Any help or advise would be appreciated - thank you
