What information is required for ordinances to be performed? What is the minimum information required for temple ordinances? Can ordinances be performed without event dates and places? Can sealings be performed if the mother's name isn't known? Should I use a woman's maiden nameView blog or married name? Can sealings be performed if the father's name isn't known?
A minimum amount of information about deceased persons is required before temple ordinances can be performed on their behalf.
As soon as the new FamilySearch website has enough information to uniquely identify the individual, it clears required ordinances.
For individual ordinances, you must have the following information:
Name: Complete names are preferred. Partial names are acceptable if that is all you can find. Use the maiden name for females.
Gender: The gender must be either male or female.
The system requires a place of death (at least the country), and any known death date information. Persons born at least 110 years ago or married at least 95 years ago are assumed to be dead. Persons whose children were born at least 110 years ago are assumed to be dead. Even persons assumed to be dead need at least the country where the person died.
A country for birth, christening, marriage, death, or burial
A standardized place for birth, christening, marriage, death, or burial is required. The standardized place must contain at least the name of the country.
Enough information for the new FamilySearch website to uniquely identify the person
This may include the following information:
Dates and places of events, such as birth, christening, marriage, death, and burial.
Names and relationships of family members, such as parents, siblings, spouse, children, and grandparents.
For a sealing to parents, you also need to know:
The name of at least the father
You must provide at least his given name or surname. Also provide the mother's name if you have it.
While it is possible to perform ordinances with minimal information, careful research for accurate and complete information before ordinance work will help prevent duplications. In the end, this will help accomplish more work for ancestors.
