Hello there emmalemon03,
Thanks for posting here on the Apple Support Communities! This is a place where other Apple users can submit questions or respond to others to help lend a hand. Let's take a closer look as we do our best to provide some additional insight.
We like to start by offering our condolences on your lost, and we sincerely wish you and your family the best. From here, the next step is to review this specific resource that goes over all possible options when something like this happens: How to request access to a deceased family member's Apple account
We hope this helps get you pointed in the right direction.
Take care.
