That's what I read NotTooOld - and it's the experience of a couple of women I know. One had a 10 year relationship, shared a home for that length of time, contributing to bills etc and has 4 year old child from the relationship. Relationship ended and she was told by different lawyers, that as her name wasn't on the mortgage etc and they weren't married, she has no legal right to a share of the property or any financial support. She's worked part time but had to go full time to keep herself and her child - she does get maintenance but a minuscule amount imo when you consider what the ex earns.
I don't know about Jerry but I did read during their separation that he'd claimed their beach marriage wasn't legal therefore she wasn't eligible for maintenance, other than for their children, some of whom were young at that time.
