I am losing my inheritance because no Will has been probated.

You need to hire an experienced estate attorney to help you figure out what to do. I am assuming that your mother lived in Georgia at the time of her death. If your mother and stepfather actually made a joint Will (which would have been a very bad idea), and if the Will was admitted to probate or simply filed with the Probate Court for informational purposes only at your stepfather's death, then the probate court of the county in which your stepfather died probably has the original Will. If your mother did not make a new Will after your stepfather's death, then that joint Will will likely need to be probated now. If you think that Will was revoked by your mother after your stepfather's death, and you can't find out whether she made a new Will, then you may want to consider seeking Letters of Administration for your mother's estate. This is not a forum suited to providing legal advice and help, however, and you'll need to work with an attorney who can review the facts in depth with you and then help guide you through the issues discovered.
