Hi, I am a 36-year-old Australian man who had a brief relationship with a Canadian woman 10 years ago. We met in Sydney and after approximately 6 weeks she fell pregnant. At this time, her visa was to expire and she would return to British Columbia and my daughter would be born there. I packed up my house and belongings and we agreed to give the relationship a go for the sake of our unborn daughter. After a month or so of living together, it was clear our relationship wasn't going to work. I was there for the birth of our daughter and I returned home about a month after she was born. It nearly killed me. After 6 months back in Australia, I felt a large part of me was missing and the mother and i agreed that I would return and give it another go. After another 12 months, we had to separate. It was clear this relationship between the mother and I wasn't going to work. From the moment, I returned back to Australia. We had an agreement that I would pay 800 per month Child Support. This was based on the fact that I would receive regular updates, photos, etc. on my daughter's life. I honoured this agreement. I took another visit over there to see her when she was 3 years old. Soon after I returned home from the visit, the mother changed her way of thinking and thought it would be best for my daughter to not be involved with me. She moved into another relationship and would try to push me aside in order for my daughter to form a father/daughter relationship with her new partner. I would no longer receive photos, updates anymore. I continued my honour to pay child support up until 3 years ago when I stopped. This wasn't fair. I was not allowed to have anything to do with my daughter. The mother did not contest my decision. She was happy enough with trying to get my daughter to bond with the new father figure in her life. A few months ago, the mother has reached out to me and told me that she is willing to let me back in my daughter's life. Her relationship has failed with her partner and she wants my daughter to get to know me again. I am thrilled. She is also asking for child support to be paid in arrears back to 3 years ago. I am wondering where I stand with this and how far back she can legally ask for child support payments. I would also like to know if anyone knows a lawyer in Australia that can help me with Canadian Law.
