"Memorials are transferred for relatives with these close relationships: child, spouse/partner, sibling, parent, grandchild, great-grandchild, grandparent, great-grandparent, niece/nephew, great-niece/nephew, aunt/uncle, great-aunt/uncle, or first cousin. This would include adoptive, step and in-law versions of these relationships.
The above is copied and pasted from the FG guidelines
If two members are related within these guidelines and both would like to manage the memorial, the member with the closer relationship should be given management."
