Well , it is possible that both the couples could be found at fault. In this case, either of you could use the fault of the other as solid grounds for a divorce. This situation is very interesting, as, at one time fault by both parties sort of void out the other. But it is only if both the husband and the wife were having affairs, then neither of them could claim the fault of the other in order to get a divorce. They were then stuck together in the marriage. So you could imagine, that this result was less than agreeable and makes very little sense.
The grounds are thus , typically set forth by the spouse who is standing up to file for the divorce. Likewise , it is up to the non-filing spouse to file a response to the petition or complaint either accepting or opposing the stated grounds.
It is also very common for both the spouses to not agree about the grounds of the divorce, but the non-filing spouse may choose not to argue over it, so the divorce process will take its path in a quicker fashion. :eek:

That’s really good information pride.
I must appreciate your effort. Hopefully it will help Louis in helping his brother.
I too agree with your view regarding divorce cases where both spouses are responsible for the breakup.
