It is not enough just to have an estate plan. You need to make sure that it is actually up to date. This is a constant process. Writing a will and then forgetting about it for 10 years does not help anyone. Your assets could change significantly in that time.
For instance, people now have far more digital assets than they used to control. Some are digital products, like movies and books. Others are digital forms of money, such as bitcoin. Some are just things that, though not really valuable at all, have a sentimental value for your family. Examples could be all of those pictures that you keep online.
