When can you alter a child custody order?

On Behalf of | Aug 25, 2026 | Family Law

Child custody orders are used to create expectations about parenting rights and responsibilities, and they’re typically used when parents are unmarried, separated or divorced. Child custody orders are always established according to the child’s best interests – not what the parents might prefer.

However, a child’s needs can change over time. What worked when a child was a toddler may no longer work for a school-age child, let alone a pre-teen or teenager. Sometimes, a parent’s ability to manage their child’s care can also change. When this happens, parents may request a child custody order modification from the court. 

What is considered a substantial change in circumstance?

A judge will not allow a child custody order to be changed for just any reason. Parents may need to prove there has been a substantial change in circumstance that impacts their child’s best interests. Here are a few examples of a substantial change in circumstance:

  • Schedule changes: A new work or school schedule may conflict with a custody schedule.
  • Relocation: Parents moving because of work, school or housing options may create a greater distance between parents.
  • Medical conditions: A serious medical condition that impacts a parent or child may change when and how a child is cared for.
  • Safety concerns: A parent may fear for their child’s safety if there are signs of abuse, neglect or abandonment.
