Hubby and i successfully faded by simply moving out of the territory and never attending a meeting at the new location. The secretary couldn't request records when he didn't even know we were living in his territory.
Our records sat in our old cong for years until the CO had a fit and insisted we be accounted for. Eventually, we got a phone call from an elder in the new territory that we didn't answer. Now, 7 years later we moved back to the previous town but different territory. (for other reasons) We received one e-mail from an elder in our original cong inviting us to the memorial. Hubby replied thanking him for the invite, saying we were keeping up with all things JW, and are not in his territory/jurisdiction and DID NOT DISCLOSE our location. We haven't heard another word. When JWs come to the door we don't answer.
Most elders aren't very persistent. Stay out of sight out of mind. Avoid attracting any attention to yourselves. Don't tell them your new address.
