modification of modified child support

[lighthouse0000]

What is the name of your state (only U.S. law)? Colorado

If an ex-spouse has already modified child support (but hasn't paid it from the time it went into effect 20 months ago...) can he go back and have it modified again?

Can he 'be forgiven' of what he hasn't paid for the past 20 months by the court?

can he be entitled to tax deductions on years when he was not up to date on child support payments?

What is the basis for ex wanting to modify?

If YOU are willing to forgive arrears, AND you never collected public assistance, yes the arrears can be forgiven. Otherwise, No.

What does your court order state regarding which parent is entitled to the tax deduction?
