After your loved one passes away, you will likely dread the day when you have to start going through his or her belongings. This is often a very difficult time for family members. If your loved one had a will, this process might be a bit easier because it would include information about who get what; however, this isn't always a smooth process.
Anytime you have to deal with the legal system or courts, it can be stressing. While there's typically nothing to fear from the probate process, there might be a lot at stake.
