JDF 1420: Answer the Modify Motion
JDF 1420 is Colorado's response when the other side has already filed a motion to modify. Your job is to address their requested changes with readable agree-or-disagree positions and proof that matches dates. It is not the moment to file a parallel "whole new case" story like an opening JDF 1413 narrative unless procedure actually calls for it. Reaction discipline beats volume.
| Response posture | Wrong posture |
|---|---|
| Paragraph-by-paragraph position on their relief | Generic "they are awful" without tying to requested orders |
| Exhibits indexed to specific dates and claims | Haystack folders that bury your best facts |

JDF 1420 questions
What is JDF 1420 actually asking me to do?
Answer the other party's motion to modify with your position on each requested change, tied to dated facts and a small exhibit set. You are in a reaction lane with deadlines, not rewriting the case from zero.
What should I read before I type a single paragraph?
The motion line by line, the current orders they cite, service deadlines, and local rules. Skim-reading the relief requested is how parents accidentally concede half the motion.
How is this different from JDF 1413?
JDF 1413 is an opening allocation petition posture. JDF 1420 responds after someone else already asked the court to change existing orders. Different caption, different reader expectation.
