The first type of post-judgment relief that can be sought by motion is relief under C.R.C.P. 59. C.R.C.P. 59 allows for a party to request post-trial relief by motion.

There are 4 different types of relief that may be sought under the rule, they are:
(1) a request for a new trial on all or some of the issues litigated at the original trial;
(2) judgment notwithstanding the verdict, which is a motion requesting a different judgment, usually in favor of the moving party;
(3) amendment of the court’s or jury’s findings; or
(4) amendment of the judgment entered after trial. These types of relief are discussed further in the next paragraph.

The second type of post-judgment relief available after a judgment or order is entered is that under C.R.C.P. 60. Relief under C.R.C.P. 60 may be sought for a variety of reasons.
First, if there is a clerical mistake in the judgment or order, for example, the failure of the court to include interest or properly calculate damages in a judgment, then relief may be sought under the rule. Motions seeking relief of this type may be made at any time after the judgment or order has been entered.
Secondly, C.R.C.P. 60(b) provides relief in 5 other circumstances, those are

(1) where mistake, inadvertence, surprise, or excusable neglect has occurred;
(2) where the adverse party has engaged in fraud, misrepresentation, or other misconduct during the lawsuit;
(3) the judgment is void, for example, if the party was never appropriately served with the lawsuit;
(4) the judgment has been satisfied, released, or discharged, or a prior judgment on which it was based has been vacated, or it is no longer equitable that the judgment has prospective relief; or
(5) any other reason justifying relief from the judgment. The next paragraph discusses timing for filing motions under C.R.C.P. 60.

Finally, the last form of relief a person may seek after a judgment or order has been entered is to appeal the judgment or order to a higher court for review. Note that there is no requirement that relief be sought first before the trial court, for example, through a C.R.C.P. 59 motion or C.R.C.P. 60 motion. An appeal can be sought directly after the judgment has been entered. However, if a C.R.C.P. 59 motion is filed before an appeal is filed, then the judgment or order may not be appealed until after the motion is ruled on. Additionally, once an appeal is filed, the trial court is divested or jurisdiction of the case and thus, parties can no longer seek post-trial relief in the trial court. If a party wishes to appeal a judgment or order, under Colorado Appellate Rule 4 they have 49 days to file a notice of appeal after the judgment or order is entered. Lastly, it is worth noting that denial of a C.R.C.P. 60 motion is appealable independently of an underlying judgment and thus, if the motion is denied, it is a separate appealable event.
