The notes are in pdf format, so you'll need Acrobat Reader on your PC. You've almost certainly already got it but, if not, you can download it from here:

There are separate notes for a 'property & affairs' LPA and for a 'personal welfare' LPA.
The property & affairs notes are here:

The personal welfare notes are here:
http://www.publicguardian.gov.uk/docs/LPAPW_No tes_1007.pdf
However, if you're missing the notes, there might be other paperwork you need as well. You can download complete packs, each containing 8 relevant documents from these links:
Property & affairs:
http://www.publicguardian.gov.uk/docs/lpa-crea tion-pack-property-and-affairs.zip
Personal welfare:
http://www.publicguardian.gov.uk/docs/lpa-crea tion-pack-personal-welfare.zip
Those downloads are zip files. You should save them to somewhere suitable on your PC (e.g. the desktop or 'My Documents') and then double-click (or right-click) the icon to 'unzip' them, so that you can see the 8 separate documents.
