You can enroll your Colorado judgment in California and then file an action here to modify child support. Waiving child support is unenforceable. Someone has a right to support depending on income and timeshare. You can waive spousal support, but not child support. Child support is modifiable. The Court has the right to decide who gets to claim the child for tax purposes if you can't agree.
This response is for general information purposes only and does not constitute an attorney-client relationship, nor is it legal advice to be relied on. I recommend an in-person consultation with an attorney who can gather more information.
