Parenting & Mental Illness: A Custody Decision

A Manitoba Court recently examined the relationship between mental illness and parenting when it was asked to rule on the issue of custody with respect to the children of a divorced couple who were dealing with the mother’s Delusional Disorder diagnosis and the father’s violent temper.

In Ulloa v. Ulloa, the parties each took the position that the other parent should not have primary care of their three young children.

The Mother’s Mental Health Issues

The mother contended that the father has been sexually abusing the children on an ongoing basis, and that the children had made such disclosures to her.  A psychiatrist concluded that the mother’s belief was unshakable and was of delusional proportions.  Other than this particular delusion, she had no other symptoms, and she functioned reasonably well is all aspects of her life.  Notwithstanding a Child and Family Services investigation which found that the children were not sexually abused by their father (and which noted concerns in respect to the mother’s mental health), the mother would not waver from her belief.

The Father’s Violent Temper

The evidence supported the mother’s contention that the father had a violent temper.  The father admitted that the children had seen him angry, to the point where he punched holes in the walls.  The children indicated to third parties that they did not like spending time with their Dad as he yelled and “smashes and breaks stuff”.

In Whose Care and Control are the Children Best Situated?

In what must have been a difficult decision, the Court of Queen’s Bench of Manitoba held that it would be in the best interests of the children to give the mother and father joint custody, and for them to share physical custody of the children on a 2-2-3 schedule.  (Click here for our blog on the issue of Visitation Schedules).

The Court was convinced this was not a case of parental alienation by the mother (in other words, she was not using psychological manipulation to cause the children to fear, disrespect or be hostile towards their father), and that the children loved both their parents.  In spite of the issues facing this family, the Court noted that it was clear from the evidence that the “children are happy, polite and energetic children.”  The father conceded that the mother is “a great mother”.   And, notably, the agency and medical reports indicated that the mother’s concern about the father was sincere – ie. she was not being malicious in making such allegations against the father.

In support of its order for joint custody, the Court highlighted the following:

  • The evidence of the parties and the experts supported the argument that the children had not been affected by their mother’s delusion and were functioning well;  their emotional and psychological well-being had not been impacted by the mental illness;
  • The mother’s commitment to obtain care from a doctor and be monitored demonstrated her love and affection for her children;
  • Although the children were well cared for by their mother, it was not in their best interests to be primarily in her care given her state of mental health;  the father’s concerns about the mother’s issues were legitimate and needed to be addressed;
  • The mother would be living with her mother, who was a reliable and loving caregiver;
  • It was not in the children’s best interests to be primarily in their father’s care as the children would not do well if their contact with their mother was substantially reduced; the children were strongly dependent on their mother for support;
  • The father had work to do in order to deal with his anger issues so that the children would feel loved and safe at all times.

The Best Interests of the Children

As in all child custody decisions, the best interests of the children were paramount in this case.  It may seem incorrect at first blush to allow children to remain in the care of a parent who is battling a mental illness, but this case reminds us that it’s not that simple.  The illness may not be having a negative impact on the children.  Also, the illness may be contained to one very specific idea/action by the parent, which may not affect his or her ability to parent effectively and lovingly.

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
