When I read this thread I thought I remembered something I had read last year about a man winning a judgment to get all the child support he had paid back because about a decade later he found out the child wasn't his. If I understand correctly the mother had to swear that this man was definitely the father in order to file for child support in the first place. Because he was unaware that the child could have belonged to another man he had simply accepted that it was his and for 10 years or so paid child support. Once it was discovered it wasn't his the woman had to pay back the support because she swore the child belonged to him while knowing it could have been someone else's. Any, that's the way I remember it. I don't really have time to re-read the article right this moment, but I did at least find it. Oh, it was in Georgia. Here's the link:

I don't know if it might have any bearing on 'grandma's' question here.
