An executor often has little to no advance notice, and thus can skip this section and go straight to First Week. On the other hand, if you do have some time, there are things you can do in advance which will prove very helpful:
Ask your loved one for the location of key items and documents (you don't need to discuss the details of these items if one or both of you don't want to; the main thing is to be able to find the relevant information when the time comes):
While any power of attorney will become void once the estate owner dies, you may find it helpful to have this authority in the final stages, when your executor powers have not yet kicked in, but decisions need to be made and actions taken.
Many people store important information (and sometimes valuables) in safe deposit boxes. You can ask the bank to search a safe deposit box for a will, but it's easier if you simply have access to it yourself. Consider asking your loved one to add you to the bank's list of people who are allowed to access any such boxes. See also Safe Deposit Boxes.
You may find it easier to compare funeral options and expenses in advance, so that when the time comes you've done your research and have one less thing to think about. Obviously, this is not something you need to discuss with your loved one unless you both feel comfortable doing so (see Funerals).
Don't wait for the last minute to say your heartfelt goodbyes. There are many things that people realize they wish they had said when someone passes away, and if you have the chance, take it. People sometimes shy away from doing this, because they worry that it reminds the dying person of his or her approaching death, but believe us, they already know. The dying person often greatly values hearing your appreciation of the role that he or she has played in your life, and may have a few words he or she would like to share with you as well.
