Post-Decree Modifications
When Your Parenting Plan No Longer Fits Your Child’s Life
A post-decree modification is a request to the court to change an existing divorce or custody order. Under Colorado law, parents can ask to update parenting time and decision-making, child support, and in some cases spousal maintenance, when life has changed since the original order. I help parents in Boulder County, Lafayette, Louisville, and the surrounding Colorado Front Range do exactly that.
Court orders are written for a moment in time, but children don’t stay in that moment. They are constantly changing.
The schedule that made sense for a toddler can fall apart once school, activities, and friendships take over. A parent’s new job, a move, a health issue, or a blended family can change what your child needs almost overnight. And sometimes an order simply never worked, because it was built around a co-parent who doesn’t follow it.
If that sounds familiar, you’re not stuck. Colorado law allows families to ask the court to update parenting time, decision-making, and child support when life changes. That process is called a post-decree modification, and it usually starts with a Motion to Modify filed in the same Colorado court that entered your original order.
Putting Your Children First, Again
A modification isn’t about reopening old wounds or winning a second round. It’s about making sure the order you live under matches the child you’re raising today.
Every case I take starts with the same question: What are your kids like? Who are they? What do they need? From there, we look at what’s working, what isn’t, and what kind of change would actually make daily life better for your family.
When the other parent makes co-parenting impossible
Many parents who come to me aren’t looking for a fight. They’ve tried to make things work. They’ve been flexible, swallowed their frustration, given grace, and kept their kids out of the middle.
But some exes use unclear wording to their advantage, ignore the schedule, or turn every exchange into conflict. When that happens, the current order may no longer protect your child or give your family any peace. Asking the court for a better structure isn’t being difficult. It’s being a parent and protecting your children.
What can be modified after a Colorado divorce or custody order?
Adjusting the parenting schedule
Changing weekday overnights, exchange times, holidays, or summers, or moving toward a more equal schedule, is often the most straightforward kind of parenting time change. The court’s focus is simply what’s best for your child.
Changing where your child primarily lives or who makes major decisions
These are bigger changes, and Colorado sets a higher bar. The court generally keeps the current arrangement unless both parents agree, or the situation has changed in specific ways, such as one parent consistently leaving decisions to the other, or the current arrangement harming your child’s physical health or emotional development. Courts take these requests seriously, and they need to be built carefully.
Protecting your child from harm
If your child is in danger during the other parent’s time, the court can restrict or supervise that parenting time, and emergency requests are heard quickly.
Child support
Child support can be updated when there’s been a lasting change in income or parenting time. As a general guide, the new calculation needs to differ from the current amount by at least 10%.
Maintenance (spousal support)
Maintenance can sometimes be changed if circumstances shift enough to make the current terms unfair, unless your agreement made it non-modifiable.
Property division
Dividing property is usually final. One important exception: if your ex hid or misstated assets during the divorce, you may have up to five years to ask the court to revisit it.
When should you file a motion to modify in Colorado?
Don’t wait on support
A change in child support or maintenance generally only goes back to the date you file your request, not the date your circumstances changed.
Bigger parenting changes have waiting periods
If a request to change where your child primarily lives or who makes major decisions was decided in the last two years, you may have to wait until two years have passed, unless your child may be at risk under the current order. There are exceptions to this rule, though, so it’s important to talk to an attorney if you’re in the two-year period.
Your own story matters
Requests to change parental responsibilities are supported by a sworn statement from you explaining what has changed and why. The court often decides from those statements whether the case moves forward to a hearing, so it’s important to get them right. I would advise you to work with an attorney to make sure your sworn affidavit makes an impact.
Agreements need court approval
Even if you and your co-parent work out a new arrangement together, it should be submitted to the court. An informal agreement, like one worked out over text, generally can’t be enforced if things fall apart later.
You have something you didn’t have the first time
Many attorneys avoid post-decree cases. Some assume a returning parent must be high conflict. Others don’t want to sort through a case that once belonged to another attorney.
I see it differently. By now, you know exactly how your order plays out in real life. You know where the gaps are, how your co-parent responds to them, and how your kids are really doing. You also understand the legal process far better than you did the first time. That knowledge is valuable, and it puts you in a strong position to build an order that truly works.
A job loss, a significant medical issue, or an increase in a child’s specific needs can all justify a new look at the numbers. While the paperwork can be a hassle, it matters. I encourage you to keep detailed records of your expenses now. If you need to show a judge that the current order is no longer fair, that proof will be our strongest tool.
FAQs about post-decree modifications in Colorado
What is a post-decree modification in Colorado?
A post-decree modification is a request to the court to change an order that was entered in your divorce or custody case. In Colorado, parents can ask to modify parenting time, decision-making responsibility, child support, and sometimes spousal maintenance when circumstances have changed since the original order.
How much does child support have to change before it can be modified?
As a general guide, the new calculation needs to differ from the current amount by at least 10%, and the change in income or parenting time must be lasting rather than temporary.
My co-parent and I agree on a new schedule. Do we still need to go to court?
Yes. Submit the agreement to the court for approval. An informal arrangement, like one worked out over text, generally cannot be enforced if things fall apart later.
Can I change my parenting plan if the other parent won’t follow it?
Yes. If your co-parent ignores the schedule, uses unclear wording to their advantage, or turns every exchange into conflict, you can ask the court for a clearer or different structure. Asking for an order that actually protects your child is not being difficult. It is parenting.
Is there a waiting period to change where my child lives or who makes major decisions?
Often, yes. If a request to change primary residence or decision-making was decided within the last two years, you may have to wait until two years have passed, unless your child may be at risk under the current order. There are exceptions, so talk to an attorney if you are inside that window.
Does a child support change go back to when my circumstances changed?
Generally, no. A change in child support or maintenance usually only goes back to the date you filed your request, which is why it is important not to wait.
Can property division be changed after a Colorado divorce?
Dividing property is usually final. One important exception: if your ex hid or misstated assets during the divorce, you may have up to five years to ask the court to revisit it.
