Do I have to give my income information to my ex every year?
Short answer
Yes. In Quebec, parents have an obligation to keep each other informed of their respective financial situations, since the amount of child support depends directly on their incomes.
In detail
JuridiQC confirms this obligation in its true-or-false list: it is true that parents have to share their income documents every year, because they have “an obligation to keep each other informed” of the other's financial situation.
The logic is simple: support is calculated from both parents' incomes. If one of them sees their income rise or fall significantly and the other does not know about it, support stops matching reality and it is the child who bears the consequences.
It is also this annual exchange that makes it possible to identify a change in circumstances that could justify a review, whether by agreement, through SARPA or through the court.
What to document
An annual file, year by year: your income tax return, your notice of assessment, and proof that it was sent to the other parent, with the date. Also keep the requests you made that went unanswered — that is what will support an application for disclosure of documents if you have to go to court.
Put your facts in writing, free. Writing your version down early, keeping your documents dated and preparing your questions for a lawyer: the tool is there to document, never to advise.

What this page is not
This is general legal information about the law of Quebec and Canada, dated and sourced. It is not legal advice, not a strategy, and not a prediction about the outcome of a case. In Quebec, only lawyers and notaries may give legal advice (Act respecting the Barreau du Québec, ss. 128 and 133). Laws and amounts change: the official source always prevails over us.
