That is from the operational manual for evaluating a spousal relationship. It isn't a 100% accurate, complete, or guiding document. That is to say that if there is proof that is different or not quite in line with the above, it may still be accepted. There may also be instances where applicants have ALL of what is in that list and still have their relationship questioned.Understood Man, thanks so much. Please see my comment above. I just found it online, it states what the OP can use for common law
It's a good thing to read and understand but it isn't definitive.
