If you have little to leave your survivors you probably don't need to do any planning beyond making a basic will, powers of attorney, and health care directives (all of which you can make with WillMaker).
On the other hand, you may want to take another look at your situation and possibly do some additional estate planning to:
If your estate is moderate to large, you should think about planning to avoid probate. Putting to work even a few simple probate-avoidance devices can save your inheritors a bundle. Tax planning is more complicated, but it's also something you won't need to worry about unless you have a very, very large estate. Finally, if you have reason to want to place controls on the property you leave, you'll most likely want to see a good estate planning lawyer.
