I know that when someone dies, the person wanting to complete the work needs to wait one year. Does it matter the age of the person that died? Ex: 14 years old
There are some exceptions. See the General Handbook 28.3.1 and 28.3.2. These exceptions only apply to people baptized in this life who would have qualified for a temple recommend at the time of their death "who would have gone to a temple but were prevented for reasons beyond their control." (not those who just never got around to it.).
Thank you for contacting FamilySearch Community. Here are the guidelines for performing temple ordinances for those who have passed:
"If a person has not been deceased for a year and a day, Family Tree shows the ordinance status of "Not Ready." Family Tree does not allow you to reserve ordinances for a person until one year and one day after the date of death. The calculation is based on Greenwich Mean Time, not local time zones.
You cannot reserve the ordinances until the waiting period is complete. If this ordinance status displays in error, it usually means that Family Tree lacks the correct death date."
Regarding the exceptions as given in the handbook to the general guidelines, you need to take care of such directly with your temple. Family Tree is not programmed to handle these.
If this 14 year old you mentioned is not just a theoretical question but was a worthy, active, Aaronic priesthood holder or worthy, active young woman who recently died, (if this is the case, I'm sorry for your or your friends' loss), there is no waiting period. Speak with your bishop or temple office as to how to get ordinances completed.
A 14 year old non-member or a 14 year old member who would not qualify for a temple recommend would have to wait the year.
Thank you for this additional information. She was a member of our ward that was suffering from depression. I was not familiar about someone this age and how long they needed to wait to complete the temple work for her. I know it will help her parents when that work has been completed.
