Executor responsibilty

[birdsong]

I have agreed to act as executor for an elderly relative who has early dementia. In reading on line advice I note that on her death I will be responsible for reporting any gifts she may have made in excess of £3000 in the 7 years prior to her demise. In the event that I am not informed of all such gifts she may have made, how can I best keep track of them; and would I bear any personal financial responsibly if through lack of information I could not report them.
Are there any public records of gifts I could consult?

You will have to make reasonable enquiries, including reviewing the bank statements to determine whether they might have been any gifts.

Also sensible to ask people who are likely to have received gifts (usually just family).
