I was wondering if a deceased person who is a member of the Church can be sealed right away to their family, or is there a waiting period?
Normally ordinances can be done one year and one day after their death.
However, "The one-year waiting period for temple ordinances does not apply to worthy members who would have gone to a temple but were prevented from doing so in life for reasons beyond their control."
