I'm back, and I'm sorry that I have been away from the site for a couple of days.
Normally, I'd say that you're right. But I don't want to give you a definitive answer, for a few reasons:
1) If I tell you that you are out of luck and I'm wrong, you won't know it and you won't act on it
2) I'm not a British Columbia lawyer (which isn't a problem, except that I don't have experience in this particular issue, given that...
3) BC's family and matrimonial laws underwent a substantial revision recently, and it's possible that your right to make claims for property division, if no longer valid, could be "grandfathered in".
You really need to consult a family lawyer near you for a face-to-face consult on the issue. Many lawyers give free consults. Don't let this go until you have a firm and reliable answer one way or the other.
I'm not going to ask you for a rating or accept because I didn't answer you. I observe that you put a deposit down to the site in order to ask this question, and that's fine. The site still holds your deposit.
I'm going to opt out as your expert. There's another here on the site who is from BC, if he's around and active you may hear from him. If you don't, then see a lawyer near you in person and don't forget about your deposit to the site. You can ask for it back from customer service.
