Supporting documents for naturalisation for spouse

[thunderera]

Hi,
According to the supporting documents on the last page of the Form AN, it needs spouse's british passport/birth certificate and marriage cirtificate.

However on Form AN guide lines, supporting documents required it mentions that either british passport/naturalisation certificate/birth certificate and marriage certificate are valid.

I havent applied for the british passport and wondering if can use my naturalisation certificate for the application for my wife.

Thanks.

The naturalisation certificate is fine to support a spouse application (together with a marriage certificate).
