Hi there, I have a son, and the last time my ex saw the child was last year Feb 2014. Before that, he hadn't seen the child since 2011 (briefly), and before that he hadn't seen him since I walked out and left our Melbourne home in 2008. I'm now married and my family and I are going on holiday to South Africa in January 2016. Due to child trafficking, the South African immigration/border protection needs all children who are not travelling with both birth parents (who are listed on the birth certificate) to give an affidavit giving the other parent the right to travel with the child. I've been trying to get my ex to sign the paperwork, even drove to his place and giving it to him. I still haven't heard from him or received the paperwork back. I need to complete our travel arrangements and need the paperwork back. My question is, if he doesn't sign the paperwork, how do I go about getting custody of children?
