Key takeaways
  • In a private domestic adoption, a birth parent has 21 days after consenting to change their mind.
  • If the consent of someone who has not signed is needed, the applicant can ask the court to dispense with it by motion.
  • A person who wants to oppose must serve and file an Answer (Form 10), or the court may proceed without further notice to them.
  • Whether a particular person counts as a parent whose consent is needed depends on the facts, and a lawyer can confirm.

Consent is one of the most sensitive parts of an adoption. Birth parents want to know whether they can be forced to give up a child, and adoptive parents want to know what happens if a birth parent will not sign.

This article explains how consent works in the adoption routes Ontario describes, what the court can do when a person has not signed, and the 21-day period that follows consent in a private domestic adoption. Details vary with each family, so treat it as a starting point.

Where consent fits in the different adoption routes

Ontario has several adoption routes. Public adoption is for children in the permanent care of a children's aid society, called children in extended society care (formerly Crown wards). Private domestic adoption is arranged through a licensee, and the ministry must approve the adoption plan before the child is placed.

Relatives living in Ontario, with examples including a niece, nephew, grandchild or stepchild, can apply directly to an Ontario court for an adoption order, and no licensee is needed. In a public adoption, the society finalizes the adoption in an Ontario court, which issues the adoption order. How a birth parent's consent is handled in a private domestic adoption depends on the facts, so it is worth confirming with a lawyer.

When someone has not signed

If the consent of a respondent who has not signed is needed, the applicant can bring a motion to dispense with it, meaning to ask the court to go ahead without that consent. The respondent must serve and file an Answer (Form 10) to oppose. If they do not, the court may dispense with consent without further notice to them.

This is why paperwork deadlines matter. A birth parent who receives court documents and wants to be heard should not ignore them, because the court may proceed without the person if no Answer is filed.

There is also a separate court form for dispensing with a parent's consent before placement, Form 8D.1, Application (Dispense with Parent's Consent to Adoption before Placement). Check the current version of any form before using it, as versions can change.

Who counts as a parent?

People often ask about unmarried birth fathers. Whether a person counts as a parent whose consent is needed can depend on the facts, such as whether parentage was acknowledged, whether the person supported the child, or whether a court order exists. A court can rule on that status, so the outcome varies. This is a point where a lawyer's advice about your specific situation really matters.

The 21-day period after consent

In a private domestic adoption, a birth parent has 21 days after consenting to change their mind, and the licensee then returns the child to them. This means that signing does not necessarily close the door right away. Our companion article on changing your mind after signing covers this in more detail.

After placement, the practitioner makes at least three visits in the first six months. The adoption is not finalized the moment consent is signed, because a court order is still needed.

What to do next

If you are a birth parent, keep copies of everything you sign or receive, and read court documents as soon as they arrive. If you are an adopter, ask your licensee or lawyer early which consents are needed and whether anyone has not signed.

Frequently asked questions

What happens if a birth parent ignores the court papers?

A respondent who wants to oppose must serve and file an Answer (Form 10). If they do not, the court may dispense with consent without further notice to them.
