CRA will not contact as he was living with you when husband claimed him. Now at his age, you can only claimed his tuition and book and if you are paying for them, make sure you have the receipt and it will be fine.
My ex also claim one of my child and that did not go anywhere as he was not living with ex.
Face it, you would be paying CS who depend on your hubby salary would be higher or lower. Children can remain on extended health benefit till 21 while in school and there is also plans available to student.
So really, I do not see the big deal here, If you prefer you could just pay the equivalent of CS and she would not be able to claim any rent or harrass you for any increase as this would cover it. 2 years will go by fast, average litigation last longer than that and would cost you.
At that age a child will respect you to not get involve and let your hubby deal with it. At 19, he is old enough to judge for himself and basically if you were paying for school residence, it would be much higher than that and there are not tax deductible.
Not sure your getting the point. We are not thinking of going to court at all we pay everything the son needs the mother pays nothing! NOTHING! Yet she threatens to take us to court everytime she has a tantrum. She has emailed us saying she is monitoring our financials as well as pictures and interviews being collected on our family. Or threatens to call CRA. She is every which way crazy. She is harassing constantly and interfering with my husband and his sons relationship. At 19 he is not a child. As for paying residence we have RESP for that and his mother wouldnt be benefitting from her SON living in her house or have any reason to contact my husband. The day the son moves to residence will be a welcome change.
