Now keep it safe: three things
- Keep your photos and files unedited. The receipt only matches the originals. Put them in an album such as “My records”.
- Save this receipt to your camera roll.
Keep the receipt file too. The image is a handy copy; checking needs the file.
- Email it to yourself.Email it to myself

How to keep notes that hold up
Write notes as soon as you can. Keep the original account rather than replacing it later; the venue decides what weight it gets.
- Write it down straight away, on paper or in the box on a step.
- Put the date, time and place at the top, and who you spoke to.
- Use their words where you can; separate what you saw from what you were told.
- Sign or initial a paper note, photograph it and add the photo.
- Never edit an old note. Add a new dated entry when something changes. A device save time is not independent time evidence or proof of event order.
