If you follow the instructions of those sites, your will will not be valid in Georgia.It takes 20 minutes or so to go to eforms.com and do a will. Probably use legal zoom and do the same. They have a form, just fill in the blanks. By Ga law it has to be notarized and witnessed by two people who are not heirs. My bank will do that for me. It is better to have it done then no questions about what your wishes were.
There's more to a will than slapping some words on a piece of paper.
