It would save a lot of time if they would put in https://www.familysearch.org/help/helpcenter/article/do-i-need-permission-from-the-closest-living-relative-to-do-temple-ordinances that written permission is required for proxy work and the format that the permission should be done. I wasted a month waiting to get the church to release the names after getting verbal permission from next of kin.
Length of time to get permission. I have been waiting over9-10 months and have forwarded my aunt's son's permission to allow me to do his mother's temple work. I have already completed her parents with permission as well as her husband, my father's brother. She is identified as Frances D. Coulson LXNK C2T. I really would appreciate you assistance so I can complete my families ordinances.0
