How should honorary doctorate degree be written?

An honorary doctorate degree should be written as "Doctor of [Field] Honoris Causa" or simply "Honoris Causa" following the name of the recipient. For example, if someone received an honorary Doctor of Letters, it would be written as "John Smith, D.Litt. (Honoris Causa)." This format acknowledges the honorific nature of the degree without implying the recipient has completed the standard requirements for a doctorate.
