--"Will the amount of child support be reduced when he has a second child because his income is currently the only income coming into the house?" -- No. Unless there's a claim for undue hardship, which is difficult to prove, the child support will stay the same. Your DH's son was born first, and the court takes this into consideration. Their view is if you can't afford the child support, you shouldn't have any further children.

--"I'm also planning on going to work when baby will be approximately 6 months old.Will my work income also be calculated as hubbys income and will me working in the future increase the amount of child support that hubby has to pay?"-- Again, no. Only the income of the biological parents is taken into account, but agian, if there's an undue hardship claim, then the HOUSEHOLD income for each parent is taken into account, not just the bio parent.

--"Does anyone know about child support laws in the province of Quebec?" -- Do a search for the Canada Federal Child Support Tables, then look up Quebec, you should find answers to your questions.

-- "I'm very curious because with the amount hubby pays for child support it seems like we're going to have a very hard time getting anything for our baby which seems unfair." -- Again, the court generally holds the view that if you can't afford current child support, you shouldn't be having anymore children. I'm not saying that I agree with that view, but I do understand it.

Your DH should be talking to an attorney about these issues. If he can't afford one, consider looking into Legal Aid.

I encourage more people to try and prove undue hardship; I don't think anyone ever does, because they are afraid there's no point in doing so! I'm fed up to the eyeballs of these mothers (mostly) gouging their exes through the frigging balls all the way.

My husband doesn't want to go the undue hardship route, either, even though we are living at a much lower standard of life than his ex's household. We are constantly cutting things out, living without, because of this and I am fed up.

His agreement is ridiculous, and extends beyond the kids' age of majority (19 in BC, Canada). I am currently studying different ways around this, including creating a cost neutral arrangement by having one of the little turds move in with us. And they ARE little turds, just like their momma...! She doesn't uphold her end of the agreement, which is to pay half the costs incurred for visitation. She doesn't pay, and my husbad doesn't get to see his kids. Why should he (we) pay for everything???

I know I am a little late on this, but the link to figure out Child support payments in Canada is http://www.justice.gc.ca/eng/pi/fcy-fea/lib-bib/tool-util/apps/look-rech... , good luck!!
