Hi Rupert, thanks for the reply.
Yes she is the primary applicant. Its very odd, as i have just read the app review and it clearly shows her as our married name, as does her skill select account and also the invite to apply. Its just she is now getting refered to on emails as her maiden name and also just above where you have to attach documents etc...as i said very odd.
I dont see it being a massive issue, i will attach a letter with screen shots of various correspondence and also passport/birth certs. I feel the system may be playing up...we did mention her maiden name as a previous known name and also that she travelled previously to OZ under her maiden name too...we shall see.
Thanks again
