Part I of the act applies to England, Wales and Northern Ireland.

In the case of a person who is neither a Christian nor a Jew, the oath shall be administered in any lawful manner.

A solemn affirmation may also be used where it is not reasonably practicable to administer an oath in a manner appropriate to a person's religious beliefs.

Section 6 provides that the form of a solemn affirmation is "I, do solemnly, sincerely and truly declare and affirm ..." followed by the words of the oath prescribed by law, omitting any words of imprecation or calling to witness.
