Post-Trial Relief - a.k.a. judge messed up in ruling

In a hearing over child support arrears going back over a decade, the judge said 'no' to interest on very old arrears due to laches (I wasn't trying to collect at the time and lots of time has past so interest is forfeit) and said interest would start accruing on the amount he said was owed as of the date of his judgement. Problem is there are arrears that are are 5 years old that I have been very actively trying to collect the whole time so laches would definitely not apply to those, so I am owed a couple thousand in interest on those arrears.

I can't find a specific form for it, how do I go about filing a Post-Trial Relief Motion? - Colo. R. Civ. P. 59

 

Thanks, heard from the Court's self help folks that there is no specific form for it- just make your own like you guys said.

My attorney said it would take 6hrs to do this, meaning if I was awarded what I asked for, I would just break even so that's a no.
