Email chains, photos, videos? In short, when you die they will all be entirely inaccessible to your loved ones. While this may be what you want (and plenty of people are perfectly happy for their email history to slip into obscurity, entirely unseen), if you are saving the family photo album in your Apple account, you need to do something about it now.
It is not possible to cater for this in your will, and aside from Court battles to access the data (remember Nick Scandalios's battle with Apple in 2019?) the only hope for your family and friends is that you took advantage of Apple's Digital Legacy programme during your lifetime. In "Settings" and "Security" on your iPhone you will see a new Legacy Contact option (launched last December) where you can name an individual who will be able to access your data after your death, by presenting your death certificate to Apple.
This problem is not unique to Apple and a number of providers have launched equivalent in-service post-death solutions. When reviewing your will every five years, you should include a consideration of your digital footprint and the best way to ensure that this passes in accordance with your wishes.
Until the government introduces legislation to regulate the procedures for claiming information assets after death, it is for the individual and their legal advisers to ensure that suitable planning is undertaken.
