Leaving a will is partly to make it clear who gets your things. By doing so, you would hope that you won't be splitting heirs — that is causing a rift between your loved ones if they have to decide how to share your belongings.
When you're fashioning your will, it might be a good idea to stipulate to whom you would like your individual personal possessions to go. After all, cutting Granny's handmade quilt in two would not bode well for anyone. Perhaps a discussion with your family members may prove helpful when making these decisions.
