I was brought up by my mother who had me outside of marriage. My father left her before I was born because he chose another woman, with whom he is now married and has a family. I have never had any contact with him although I do recall my mother saying he did pay some child support.
This might sound ludicrous, but isn't it right that I should be able to sue for damages? He lives a comfortable life and has not paid for his actions, other than the obligatory child support. IMO, if you have a child and then fail in your moral obligation to be there for your child, you deserve to be sued. Does the law recognise this?
