The Nikah Nama should accurately record the parties, witnesses, representatives where applicable, dower and other required particulars. A PDF exchanged by email or an electronically circulated scan may be useful operationally, but it should not automatically be described as the final statutory marriage record.
For Muslim marriages, section 5 of the Muslim Family Laws Ordinance is the central registration provision. The competent Nikah Registrar and local authority should be identified before the ceremony if possible, especially where one or both parties are outside Pakistan.
After registration, the parties may require certified or computerised civil-status documentation. For foreign use, the receiving country may also require translation, attestation, authentication or additional proof. Pakistani registration does not control the evidentiary requirements of another country.
