The wife knew about the affair, for the husband was paying child support for 19 years. At any point the wife could have bailed on the marriage, taking her half of the net family property with her. Presently, the wife could still walk out the door and take her half with her.
Concerning support, the issue is not one of the timing of the relationships (as discussed my previous post), but whether or not the second spouse cohabited with the man.
In Ontario, the statute concerning support for common law spouses specifies that either they must have cohabited continuously for a period of not less than three years, or have cohabited in a relationship of some permanence if they are the natural or adoptive parents of a child.
The fact is that they had a child, a twenty year affair, including regular sleep-overs, but no actual common residence. When seizing this up against the law, they had a child, they had a relationship of some permanence, but they did not cohabit in the usual sense.
So that is what the court is trying to decide. Did their sleep-overs constitute cohabitation.
I think it does. I think the relationship as a whole should be considered when determining if there is or was a spousal relationship. Whether the parties shared a bed for a certain number of nights per week should be a factor, but should not be determinative. If it were determinative, then that would mean that common law spouses would cease to be spouses if one were placed in assistive housing or a nursing home. If it were, then that would mean that common law spouses would cease to be spouses if one were working away from home for extended periods, as many geologists, miners, mariners, truckers etc. do.
If, all things considered, the relationship was a spousal relationship rather than a fling, then there should be support if there is a need for support and an ability to pay support. That there is another prior spouse is not relevant beyond factoring into the ability to pay.
