Wow I actually never knew that you need to report intent...interesting...I should say I never even applied for PR so please do not take anything I say as more than a very uninformed impression. Follow the more veteran users instead.
I gotta say I find it weird that IRCC want not only facts but intents...like, if the marriage is in trouble right now...what if they go to counselling then they save it after all? I mean, can we arrest someone for thinking about a crime before they even do it?
Did you read the very first post? OP flat out said that they are divorcing after PR. This is not a "maybe we won't stay together" situation.
