We just arrived here in Perth in january 2014 and when we were applying for our visas we sent all the paperwork expect for the form which my ex had to sign to give permition for my 12 year son to move to Australia and my case office said she would not give the visas until that is signed or we had to withdrew my son from the application , I was never married to him and for the 12 years he's never been in my sons life, he tired to object in short thanks be to god he signed it
