Generally speaking, the Courts like finality to apply to the divorce decrees they enter. Because the Courts do not want litigants filing motions to change custody on a whim, there better be a good reason for a motion to modify custody.
For starters, no motion to modify custody may be heard for at least one year following entry of the decree. If a motion to modify custody has been made, no subsequent motions may be made for two more years. However, these time restrictions do not apply if the Court finds that there has been “persistent and willful denial or interference with parenting time, or has reason to believe that the child’s present environment may endanger the child’s physical or emotional health or impair the child’s emotional development.” Because many motions to modify custody allege these types of facts, the exception can seem to swallow the rule.
With some exceptions, motions to modify custody must allege “endangerment,” as alluded to above. That is, the present custodial arrangement must endanger the child(ren) in some way. Stated differently, there is a presumption that the custodial arrangement will stay as it is, unless the noncustodial parent can prove endangerment. This is a high standard – higher than the “best interests” standard for initial determinations of custody where there is no presumption in favor of either parent.
If contested, motions to modify custody can be a lengthy process. The moving party must first allege facts in an affidavit which will be considered by the court at a motion hearing. The Court must then determine whether the facts as set forth in the affidavit, if true, rise to the level of endangerment. If they do, then the matter is set on for an evidentiary hearing (trial). This process can take months.
One lesson is this: Do not agree to custody terms in a divorce decree with the idea that you can try to modify custody down the road. While you can certainly bring that motion, the bar for modifying custody on a post-decree basis is much higher than the bar for an initial determination of custody during the divorce/custody proceedings.
