Please keep a couple of things in mind. Some of us, me included, claim to have a sense of humor that new folks find confusing at first.
More importantly, the various Probate Courts have, for decades, been able to do things however they chose, with no oversite. Due to the efforts of a small number of people, Malum being one of them, the rocks are being turned over. We now have a good idea of the paperwork flow, how long the process takes, and who's holding things up. Malum's question is relevent in that in most cases the paperwork to the GBI is submitted, processed and returned to the Probate Court within a few days, a copuple of weeks at most. That includes submissions to the FBI.
One of the things that confirming the status of submissions to the GBI/FBI through the Sheriff's office is that when you call the Probate Court back and you tell them when everything was processed and returned they will know that they will have a hard time blowing smoke in your ear. Especialy when you quote ORI numbers, State statutes and case law. All of which can be found here.
The information will help if you chose to contact your State Rep. and Senator with pointed questions. Like where the F is my GFL and why aren't you doing something about it! (A call to your county commissioner may get an explanation as to why your check hasn't been deposited. Unless it's Joe Thompson in which case you're out of luck.)
Once you know the process things are easy (See, I told you I had a sense of humor). Hang in there you will eventualy get your GFL.
