You are NOT "locked in" for the 2005 rates.
Even if your agreement stated that you are "locked in", (which I doubt), that would NOT hold water in court.
Child support is the RIGHT of the CHILD, and they are entitled to receive support at the level that commensurates their parents incomes.
By law, the child support payor is obligated to provide the recipient with his/her income tax return and notice or assessment and reassessment (if any),
every year, in order to ensure that he/she is paying the amount that matches income.
However, if that information is not forthcoming, it becomes YOUR responsibility to seek it out.
Not only are you
not "locked in"....you could apply to the courts for a retroactive increase since 2006.
Depending your ex husbands income, that could mean that he either owes you money, or you could owe him a rebate... you wont know until he gives you his financial disclosure.
He
has to give it to you, but you have to request it in
writing.
A retroactive adjustment usually starts from date that you asked for his financial information... however, if you have a valid reason
why you haven't pursued an increase until now.... it is common for a Judge to go back 3 years.
You will have to file a
Motion to Vary your existing court order. You can represent yourself, but you will have to do a lot of work.
There are tons of case law on Canlii.org, just search "retroactive"....
If you can negotiate an agreement with your ex, without involving the courts, that would be best.... consider mediation.
There shouldn't be any "court battle" in your situation. It is very straightforward. He must provide you with income disclosure, and you will get a new order for Child Support, there is nothing to "fight" about. The guidelines are very clear.
This site has a lot of great information, but beware of the jaded members... the information can be very biased.... if the men feel like you are attacking one of their "brothers", they can get nasty.
Good luck!!
