Great thanks girls

You don't always need a letter (but it can be safer to have one) to go overseas as long as the other parent is aware & agrees to the child being taken out of the country. My niece who is 5 is currently in Bangkok with her Father for 3 weeks, no letter was needed as both parents agreed. If he was stopped at customs all he has to do is give them my sister's number & they call her to verify.

Ok cool i want to take him to Disneyland when he's 5 for his bday that's all :)

No but it's complicated. You need to go to family law court and get orders giving you permission to go. The court gives permission if:

1/ they are confident you will come back and;

2/ they feel it's in the best interest of the child to go overseas.

Thought so that's crap :( what if I can't get in contact with him does that mean my son can't go on holidays

You need to get a letter from him. Even though he isn't on the birth certificate he is the 'acknowledged' parent. Travelling with children is governed by strict laws because of international kidnappings. They aren't allowed to make exceptions even if the father has no contact.

Oh cool thanks Hun

I think you can call relationships Australia and ask them those types of questions - good luck!

That's what I'm hoping but friends bubs dad wasn't on hers either and she had to get a letter even though he had never even seen bub so that's why I'm confused :(

I'm not 100% sure but I thought the father had to be on the birth certificate to have legal rights?

I don't think you would have to as his not on the birth certificate!
