6.4. Clearly indicate mandatory fields

On each form, mandatory fields must be clearly indicated:

  • A distinctive sign (“*” symbol, “mandatory” mention, etc.) must be provided in the label of each mandatory field.
  • If a symbol is used to declare mandatory fields, a statement placed at the beginning of the form must indicate that the symbol stands for a mandatory field.


If all the form fields are mandatory, then the statement “All fields are mandatory”, placed at the beginning of the form, may be sufficient.
