Key takeaways
  • A separation agreement can set decision-making responsibility and parenting time, but it must be in writing, signed and witnessed to be enforceable.
  • A court can disregard parenting terms in an agreement if that is in the child's best interests, so the agreement never fully binds the court.
  • If a parent does not follow a court order, the consequences can include fines or jail.

You and the other parent have separated and want to settle how the children will be cared for without a court fight. A written parenting agreement is a common way to do that, and many parents reach one through talking, mediation or their lawyers.

The details matter. How you sign it, what it covers and whether it is turned into a court order all affect what happens if the arrangement breaks down later. This article explains the main points in plain language.

What a parenting agreement can do in Ontario

Separated cohabitants may agree in a separation agreement on decision-making responsibility and parenting time for their children. Parenting time includes the right to visit with and be visited by the child, and the same right as a parent to make inquiries and receive information about the child's well-being.

Which law applies depends on your situation. The federal Divorce Act governs parenting between married spouses who are divorcing, while Ontario's Children's Law Reform Act applies to unmarried or common-law parents and to married parents who are not divorcing. The two have parallel but separately numbered sections.

What to include

A good plan is specific. Justice Canada suggests a parenting plan cover decision-making, a parenting schedule including holidays, transportation (especially if parents live far apart), vacations outside the province or country, passport applications and consent letters for travel. It also notes that a schedule suited to a teenager is unlikely to suit an infant or toddler.

Day-to-day decisions are normally made by the person who has the child during their parenting time, unless a court orders otherwise. Your agreement can say more about this if you want.

Signing it so it can be enforced

A domestic contract, such as a separation agreement, is unenforceable unless it is in writing, signed by the parties and witnessed. A handshake deal or a text exchange is not enough on its own.

Justice Canada advises each parent to show the draft plan to their own legal adviser before signing. That step helps you understand what you are giving up and whether the terms are realistic.

The limits: courts have the last word on children

A court may disregard any provision about a child's education, moral training, decision-making responsibility or parenting time if that is in the child's best interests, so an agreed plan never binds the court on these issues. The court's primary consideration is the child's physical, emotional and psychological safety, security and well-being.

Many parents choose to have the plan put into a court order. The court must include in its parenting order a written parenting plan the parties have agreed on, although it may change the plan if that is in the child's best interests. Justice Canada says a plan that is included in a Divorce Act order is legally binding.

If someone stops following it

Ontario's guidance says you can be fined or jailed for not following a court order on decision-making responsibility, parenting time or contact. A contempt motion is one way to enforce an order other than a payment order. A person found in contempt may be imprisoned or fined. A court may also make other orders it considers necessary for a just result, such as costs.

For future disputes about how the agreement works in practice, a separation agreement, court order or award can provide for arbitration of those disputes. A party entitled to enforce a family arbitration award may apply to the Superior Court of Justice or the Family Court to enforce it.

What to do next

Frequently asked questions

Do we need a lawyer to make a parenting agreement?

A separation agreement must be written, signed and witnessed to be enforceable. Justice Canada advises each parent to show the draft to their own legal adviser before signing. How much help you need depends on your situation, so it is worth confirming with a lawyer.

Can a judge ignore our agreement?

Yes, on parenting issues. A court may disregard a provision on decision-making responsibility or parenting time if that is in the child's best interests.

What is a parenting plan versus a parenting order?

A plan is what the parents agree on. A court order is made by a judge, and the court must include an agreed written plan in its order, though it may change the plan if that serves the child's best interests.

What if the other parent breaks the agreement?

It depends on whether the terms are in a court order. Not following a court order can lead to fines or jail, and a contempt motion is one route. A lawyer can explain the options for your situation.
