new user here, I have researching this kind of case for a while, and found this to be most recent "big" case of such. So I want to comment although a month late. Sorry for my english.
I have read most post from start to end, which just like MRA site's counter-article, was filled by misogyny/misandry comments early on.
some prior cases:
in Frenchmen "G" (husband) vs "B" (wife) case involving underage "A(strid)" daughter. The case is pretty much a unwanted cuckoldry where B actively in relationship with "L" since her previous marriage, current (with G) while also making A, and post-divorce. They get custody of A but the court awarded G for the money. G still want to see A and allowed by court.
Australian Liam Magill case. Wife lied to husband because she was still young and allegedly have bipolar disorder. Liam eventually lose his case. Three children are teens and siding with wife (including one husband bio children). This rather similar with Mason case in being duped for lengthy years but Liam is no millionaire.
Scott Flynn and Brandon Parsons of U.S military (the latter was cuckolded while on service in Iraq and Afghanistan) was tricked into false shotgun marriage. They had to pay CS up till the child reach 18. Brandon Parsons was financially destroyed. In former case bio-dad actively involved like french case. These two do not involve adultery.
Looks like Brandon Parsons is worst case of all (including this thread) as he is still young read on rhinoden.rangerup.com/the-curious-case-of-staff-sergeant-parsons/
Well I live in moderate muslim country (no sharia law) which still a patriarchy, here there have been active feminist movement for change of law, after reading all of these I hope my government don't make the same loophole on revised CS. I'm certain abortion will never be legal in my country even if in the future DNA test become mandatory for birth certificate signing...
