Key takeaways
  • A parenting agreement can set out when each parent has the children and who makes major decisions.
  • An informal plan can be hard to enforce, while an agreement that is filed or turned into a consent order is easier to rely on.
  • A court still checks that the parenting terms are in the child's best interests, even when you both agree.
  • Getting legal advice before you sign matters, because it can be difficult to get a court to set an agreement aside.

When parents separate, many want to settle the schedule and the big decisions themselves, in writing, without a trial. A parenting agreement (sometimes called a parenting plan) is how most families do that.

This article explains what a parenting agreement usually covers, how it operates outside court, and what you can do to make it stronger. It is general information, not advice on your situation.

What a parenting agreement does without a court

A parenting plan can set out when each parent spends time with the children and who makes major decisions. You and the other parent can reach it yourselves, with lawyers, or through mediation or another family dispute resolution process.

The catch is enforcement. Informal plans can be hard to enforce. If the agreement is a separation agreement, you can ask the court to enforce the parenting arrangement in it. The table below compares the usual levels of formality.

Form of arrangementWhat to know
Informal plan (verbal or casual)Can be hard to enforce
Written separation agreementYou can ask the court to enforce the parenting arrangement in it
Agreement filed with the courtCan be filed with the Ontario Court of Justice or a Family Court branch of the Superior Court, with an affidavit (Form 26B)
Consent orderParents ask the court to include their agreement in an order, which is simpler when both agree

Failing to follow an order without good reason can bring a fine or jail.

What to include in a parenting agreement

Justice Canada's parenting plan checklist is a useful outline. It covers the following topics:

Not every family needs every item, but going through the list helps you spot problems before they happen. A plan with a clear schedule and a clear way to make changes tends to leave fewer gaps to argue about.

Schedules, decisions and day-to-day life

Parenting time can be allocated by a schedule, and a parent has exclusive authority to make day-to-day decisions affecting the child during their parenting time. Your agreement can say which decisions are day-to-day and which are major ones that you will make together or that one parent will make.

When setting the schedule, think about practical details like who drives, where exchanges happen and what happens when plans change. Justice Canada also notes that shared time works best when parents live close to one another. For vacations outside the province or country, address passports and travel consent letters.

Children's needs change as they grow, and their views get more weight as they get older. Many parents build in a review point or a process for adjusting the plan, which is one of the checklist items.

Making the agreement hold up

You do not need a lawyer to make a separation agreement, but you should get advice before signing because it can be difficult to get a court to set one aside. An agreement is binding if you understand its terms and consequences, both of you gave complete and honest financial information, and neither of you was pressured to sign. If you used a mediator, each person should get advice from a different lawyer before signing to make a mediated agreement legally binding.

Even a signed agreement is not the last word on the children. If parties submit a parenting plan, the court must include it in the parenting order unless it is not in the child's best interests, in which case the court may modify it first. In making a parenting order, the court considers only the best interests of the child, with primary consideration to the child's physical, emotional and psychological safety, security and well-being.

Changing the agreement later

Before varying a parenting or contact order, the court must be satisfied that there has been a change in the circumstances of the child since the order was made. If you both agree to change a final order or filed agreement, the Ontario guide uses a Consent Motion to Change (Form 15C), signed and dated by both parties in front of witnesses, with Form 14B, a draft Form 25 order, and the existing order or filed agreement. Each party must also file a commissioned Form 35.1 for changes to decision-making, parenting time or contact.

If the judge grants the orders, the signed order is sent by email or in the self-addressed envelopes. If not, you receive an endorsement explaining the reasons and any next steps.

What to do next

If there is family violence or a safety concern, tell your lawyer or mediator early, because the court must consider family violence and its impact.

Frequently asked questions

Do I need a lawyer to make a parenting agreement in Ontario?

A lawyer is not required to make a separation agreement, but you should get advice before signing because it can be difficult to get a court to set one aside. If you used mediation, each person should get advice from a different lawyer before signing.

Can we enforce a parenting agreement without going to court?

Informal plans can be hard to enforce. You can ask the court to enforce the parenting arrangement in a separation agreement, and you can file an agreement with certain courts or ask for a consent order.

Does the court have to accept what we agree to?

If you submit a parenting plan, the court must include it in the order unless it is not in the child's best interests, in which case it may modify it first.

Can the children decide which parent they live with?

The court considers the child's views and preferences and gives due weight to age and maturity, but the Act sets no age at which the child's choice decides the matter. Justice Canada advises against asking children to choose a parent and suggests asking what matters to them instead.
