How Can Parents Modify Existing Child Custody Agreements?

Gutin & Wolverton: Harley I. Gutin Oct. 8, 2025

In Cocoa, Florida, parents have the right to request a modification of custody orders when substantial changes occur. Jobs change, children grow, and family circumstances evolve in ways that may require an adjustment to parenting arrangements. 

As a firm dedicated to family law, we guide parents through the process of making those modifications while protecting their rights and their children’s best interests. At Gutin & Wolverton, we know that life rarely stays the same after a custody order is entered. 

Keep reading to learn about how modifications work, when courts may grant them, and what steps parents should take if they believe an existing agreement no longer fits their family’s needs.

Child Custody Agreements in Florida

In Florida, child custody is referred to as time-sharing and parental responsibility. Courts expect parents to share responsibility for their child’s upbringing unless there are serious reasons not to. Parenting plans detail where the child will live, how decisions will be made, and how parents will handle holidays, schooling, and other important matters.

Once a court issues a custody order, it carries the weight of law. However, family law in Florida recognizes that life can change in ways that make the original order outdated or impractical. When this happens, parents can seek a modification through the court system.

When Can Custody Be Modified?

Florida courts don’t allow parents to modify custody orders simply because one parent wants more time or prefers a different arrangement. Instead, there must be a substantial, material, and unanticipated change in circumstances.

Some common examples include:

  • One parent relocating for work or personal reasons

  • A significant change in a parent’s work schedule

  • A child’s educational, medical, or emotional needs shifting

  • Evidence of abuse, neglect, or unsafe behavior

  • One parent failing to comply with the existing order

As a family law practice, we emphasize that courts will only approve modifications when the change is in the best interest of the child. This is always the guiding principle in Florida custody cases.

The Process of Requesting a Modification

Filing for modification begins with a petition to the court that issued the original custody order. The petition must clearly explain what has changed and why a new arrangement is necessary. 

The parent seeking modification bears the burden of proof, meaning they must present evidence showing both a substantial change and that the new arrangement will serve the child’s best interest.

The process usually involves:

  1. Filing a petition for modification with the family court

  2. Serving the petition to the other parent

  3. Attending hearings or mediation sessions

  4. Presenting evidence and testimony before a judge

  5. Receiving a new custody order if the court approves the change

As experienced family law attorneys, we help parents prepare petitions, gather supporting evidence, and represent them in hearings. The process can be demanding, but with careful preparation, parents can successfully demonstrate the need for modification.

Common Situations That Lead to Custody Modifications

We often see parents seeking modifications in the following situations:

Relocation Cases

If one parent needs to move more than 50 miles from their current residence, Florida law requires court approval. Relocation can significantly impact time-sharing schedules, so courts carefully evaluate whether the move serves the child’s best interest.

Changes in Work Schedules

Parents who work irregular hours, overnight shifts, or new jobs may find it difficult to comply with existing custody schedules. Courts may grant modifications to create more practical arrangements.

Concerns About Safety

If one parent engages in unsafe behavior, such as substance abuse or neglect, the other parent may request a modification to protect the child. Family law allows for emergency modifications in urgent cases.

Child’s Needs Evolving

As children grow older, their educational, social, and emotional needs may change. Courts may modify custody agreements to reflect these new circumstances, especially if the child’s current schedule is no longer appropriate.

Mediation in Custody Modifications

Florida courts often encourage parents to attempt mediation before going to trial. Mediation allows parents to work with a neutral third party to reach an agreement outside of court. If parents can agree on new terms, the court can approve the agreement and issue a modified order.

At Gutin & Wolverton, we often advise parents to consider mediation as a first step. It can save time, reduce conflict, and allow parents to maintain more control over the outcome. However, if mediation fails, the court will decide the matter based on the evidence.

Emergency Custody Modifications

In some cases, parents may need immediate changes to custody orders. Florida law allows for emergency custody modifications if a child is in imminent danger due to abuse, neglect, or unsafe living conditions. These cases move quickly, and the court may grant temporary changes while the full case is considered.

We’ve handled many emergency family law cases and know how important it is to act swiftly. Filing the correct motions and presenting evidence promptly can protect children from harm.

Challenges Parents Face in Custody Modifications

While custody modifications are possible, they aren’t always easy. Courts carefully weigh the evidence, and the burden of proof rests on the parent requesting the change. Some common challenges include:

  • Proving that changes are substantial and not minor inconveniences

  • Demonstrating that the modification truly benefits the child

  • Overcoming the other parent’s objections

  • Dealing with delays in court scheduling

As family law attorneys, we prepare parents for these challenges by building strong cases supported by evidence, not just personal testimony.

Floida Case Law and Custody Modifications

Florida courts have established that custody modifications are only granted when a substantial and material change is proven. For example, in Wade v. Hirschman, the Florida Supreme Court reaffirmed that modifications require both a significant change and proof that the new arrangement serves the child’s best interest.

We stay updated on developments in family law so we can apply the latest case law to our clients’ situations. This allows us to craft arguments that meet the court’s standards and stand on solid legal ground.

Long-Term Considerations for Parents

Parents considering custody modifications should also think about the long-term impact of new arrangements. A modification may affect school placement, extracurricular activities, and relationships with extended family.

We encourage parents to consider how their requests align with the child’s long-term stability and development. Courts will always look at the bigger picture, and parents should be prepared to show that their proposed modification supports both immediate and future needs.
