Can a Settled Custody Order be Changed?

In a recent decision of the Ontario Court of Justice (Mohammad v. Mahmood), the Court was asked to consider whether it was appropriate to change an order for joint custody to an order for sole custody in favour of the father.

Background Facts

In 2012, Mr. Mohammad and Ms. Mahmood settled the issue of custody of their two children, agreeing to an order of joint custody.

In 2014, Mr. Mohammad was granted a temporary order permitting that he move with the children from Ontario to Saskatchewan as he had obtained employment there.  The children have lived with their father in Saskatchewan since December 2014, visiting with their mother in Ontario during school breaks.  The mother initially objected to the move, but then agreed that it was best to avoid trauma and confusion to the children, and allowed them to stay in Saskatchewan.

The father then brought a motion in 2016 to ask the Court to vary the custody order from joint to sole.  He argued that he had been the primary caregiver of the children and had been looking after all their emotional and financial needs.  He also argued that the mother rarely spent her time or resources with the children due to her health problems and the need to care for her ailing father.  The mother disputed the father’s arguments, and asked the Court to maintain the joint custody arrangement.

When Might a Court Change a Settled Custody Order?

A court can change an order if either party demonstrates a material change in circumstances.  A material change is a change that, if known at the time of the initial order, would have resulted in different terms.  The change must be “substantial, unforeseen and of a continuing nature”.

Was there a “Material Change in Circumstances” in this Case?

The Court found that there had been a material change in circumstances in this case that touched the welfare of the children and the ability of a parent to meet the children’s needs.

There were in fact two material changes since the initial order in this case:

  1. The father had found new employment in another province and moved with the children with the blessing of the court; and
  1. The mother’s health had deteriorated since the date of the last order, affecting her mobility, ability, and employment.

Should the Custody Order Be Changed in this Case?

Just because a court can make a change to the initial order (having found one or more material changes in circumstances), it doesn’t mean that it will.  In this case, the Court decided that the order of joint custody was still the right arrangement in the best interests of the children.  This was true even though the parents live in different provinces.

The Court explained that the joint custody regime should remain in place because:

  • both the mother and father have something to offer the children together;
  • both balance each other’s parenting philosophy and style; and
  • they can communicate effectively with each other and schools and doctors by electronic means, even though they live in different provinces.

Distance is not an obstacle if the parents have the willingness to communicate for the sake and welfare of their children.

If you are wondering whether you might be able to change a custody order, give some thought to whether there has been a material change in circumstances in your case, and remember that any arrangement must ultimately be in the best interests of the children.

Frequently Asked Questions - child custody & access

Ontario law does not specify the age at which a child can decide which parent to live with. At most, the Court may consider the preference of the child but that does not necessarily mean that the Court will act favorably on it. The court will consider the child’s maturity, ability to articulate their desires, and the reasoning behind their views when seeking their opinion.

If a parenting plan is included in your court order under the Divorce Act, the document will be legally binding.

In order to change your child’s last name, you will have to be the child’s parent with legal custody or be the legal guardian of the child. In order to change the child’s last name, you will have to provide notice to anyone who has legal access to the child, and that may include your ex-spouse.

In most cases, the answer is no. However, there can be some exceptions that the mother can build a case upon. These include the father putting the child at risk, non-compliance with the court order, or a history of violence by the father.

Creating a custody plan with a narcissistic ex-partner is a task best left to legal professionals. While there might not be one way to deal with a narcissistic ex, there are things that you can do to turn the tables on a narcissistic co-parent. The best way to prevent problems is to go with no contact or limited contact with your ex-partner and put everything in writing if you must only communicate via email or text message to record statements and harassment.

Let us consider that the “moving away” is relocation and not just a change in residency.

Then, let us qualify that the mother will take your child with her.

If the mother is the primary caregiver of the child, you may oppose the relocation by applying the principles laid down under the Gordon vs. Goertz case. You must present your case strongly as to why potentially cutting your child’s relationship as the primary caregiver is to your child’s best interest. This situation falls under the purview of Section 16.93(2) of the Divorce Act.

If both you and the mother have equal parenting time over your child, the mother of the child has the burden of proof as to why the relocation is for the best interest of your child. This situation falls under the purview of Section 16.93(1) of the Divorce Act.

If there is no Court ordered, approved, or awarded parenting time or separation agreement, as contemplated under Section 16.93(3) of the Divorce Act, the mother has the burden of proof to show that relocation is in the best interest of your child.

Note that even if the burden of proof is not laid upon you, it still recommended that you present a strong opposition to the relocation.

Yes, it is possible for your ex to prevent you from relocating with a child you share, although this will likely plan on your parenting arrangements and decision-making responsibility. If you cannot agree about a relocation, a court will decide based on the child’s best interests.

Generally, you need to provide your ex with 60 days’ written notice of your relocation plan, and you must obtain consent or a court order to move the child. A lawyer can help you navigate this process. Our divorce lawyers will guide you through the application and court order process.

Yes, but they will need to establish paternity, especially if the father and the mother separate. Here are the ways to establish paternity as recognized by the court:

  • Act of birth
  • Presumption of paternity
  • Uninterrupted possession of status
  • Voluntary declaration
