How do I file a statement of claim / probate form when probate process has not began

You don't actually file a claim in the probate court in Georgia during a probate anyhow, although you can provide the court with a copy of your claim. All you do to file a claim in a probate matter in Georgia is provide notice to the Executor or Administrator of the estate, if there is one. If there is not an open estate, then you need to try to figure out who the most appropriate person to receive notice will be and send notice of the claim to that person. That's about all you can do.   If your case, if you have a last known address for your attorney, you may want to send the notice to that address. If you can find any alternate addresses (check with the State Bar Association), you should also send notices to those addresses as well. Try to use a delivery method that requires a signature so that you have some proof that someone received your notice.   Best wishes to you.
