I fully agree with Gracey's comments, having made enquiries for myself and other mothers over the years. I'll add some additional comments. I believe a law was passed over the past few years to enforce child support payments. Previously, a court could instruct a father to make child support payments, but did not have any law in place to force a father to do so. This new law means that a father can be stopped leaving / coming to Hong Kong should he not be up to date. However, the amount paid appears to be commensurate with however much the father earns, and a father can convince a court that he is poverty struck, or bankrupt, and have the amount paid to the mother held at a minimum. In one case I know, the father only pays $2,000 per month. It's better than nothing of course, but it still doesn't solve the problem of how to survive overall. In addition to the free legal support link put up by dressuphk, the HK law society also has a list of lawyers offering 45 minutes of free legal consultation. Don't go over the 45 minutes, or they will charge you. Visit
www.choosehklawyer.org, go to 'find legal sevice' on the left hand column, go to 'find free legal consultation', and then choose "Family Law". But my more worthwhile advice is to strive to 'keep it nice' with the father, as well as with his family. Sometimes the daddy's need some time, even a long time in many cases, to come round to accepting that they are a father. There are an incredible amount of stories out there such as yours. Fathers, both young and even older ones in their 40s have run away as fast as they can from the situation. In some cases it just scares them to death, but then they step up to the plate of the responsibility. Don't blame him, because he is where he is in terms of his path to maturity. If you keep it nice with him, then 'if' he does have any potential to come round, you won't have already blown up that path. He family might also be of some assistance which is why you should keep your relationship with them friendly. It's easy to blame him for being a bad person, but it's more constructive to try to understand the father's side of the story.
Back to the practicality of life in HK. One of the goods things about being a single parent here is that we can hire a full time helper to take care of the child and home while we work. This is a great help to single parents here that we don't have in places like Australia and the UK.
Big congratulations on your falling pregnant. I am certain that you'll look back at your decision as the best that you have ever made.
