How long do names stay on the share with temple list? What is the maximum amount of names that can be added to the list?
Here is information from a Knowledge Article found in the Help Center:
"Family names shared with the temple do not expire. Names remain on your Shared with Temple list until one of the following occurs:
"The ordinances you share with the temple initially go to the temple that is nearest you. The temple will then distribute them to people who come to the temple without their own family name cards. How quickly this happens depends on the number of ordinances that other people have shared with the temple, as well as the number of people attending the temple who need a family name card."
There is not a maximum amount of names that can be shared with the temple. As you know, we are encouraged to share names with the temple to keep our reservations list below the 300 name limit.
We hope this helps.
