There may be names such as those shown below which do not easily identify which part of the name is the family name and which part(s) is the given name. Further, it is customary for some names to show the family name first. However, the application, or any other form which clearly identifies the family and given names, will be the principal source of details. In all cases the names will be recorded in the correspondence fields in the sequence of given names (initials) then family name.
TONG TRAN VAN
WAH MAI LEE
DAVID STEVEN
STEVEN DAVID
In the above case of WAH MAI LEE the first name (WAH) is the family name. However, the name will be shown in the correspondence field Addressee Line 1 as MS M L WAH because WAH in this case is the family name.
