Family Law – Parentage

In Quebec, filiation is described under two categories: filiation by birth, which includes filiation by blood, by presumption, or by procreation involving the contribution of a third party, and filiation by adoption.

Filiation by blood (biological filiation):

• Most common method;

• Primary proof: child’s birth certificate.

Rules for establishment on the birth certificate:

• Mother: unless assisted procreation is involved, filiation is automatically established by giving birth;

• The other parent: filiation is recognized when both parents jointly declare on the birth certificate.

Presumption:

• Child born during marriage or civil union: the spouse of the mother or of the parent who gave birth is automatically presumed to be the other parent;

• This presumption applies within 300 days following the dissolution or annulment of the marriage/union;

• Legal presumption establishes filiation, even without explicit declaration.

Continuous possession of status:

• Situation where a person raises and treats the child as their own, in a public and continuous manner. For example, care provided to the child, involvement in their education, contribution to their maintenance, etc.

• Conditions: act and be recognized as the true parent from birth, for a minimum of 24 months (according to case law), except in exceptional circumstances;

• Can establish filiation without other proof;

• Makes filiation incontestable when combined with the registration of the parent’s name on the birth certificate, unless otherwise provided by law. However, there is an exception for a child resulting from a sexual assault committed by their father.

Filiation by adoption:

• Create a new permanent filiation bond between the child and their adoptive parents;

• Local or international adoption;

• May be voluntarily consented to by the parents or guardians OR ordered by the court (cases: abandonment, forfeiture of parental authority);

• Determining criterion: always the best interest of the child.

Conditions for local adoption:

• The adopter must be of legal age;

• There must be a gap of at least 18 years with the age of the adoptee (except for the child of a spouse), despite certain exceptions;

• Adoption by a stepparent (married or common-law spouse): a common situation allowing the establishment of a bond with the parent’s new spouse.

Filiation by assisted procreation:

• A technique allowing persons with difficulties conceiving a child biologically to realize their parental project;

• Most often applies to infertile couples, same-sex couples, and single persons wishing to start a family.

Parental project with assisted procreation:

• When assisted procreation involves the reproductive material of a third party (sperm or eggs) who is not involved in the parental project;

• The single person or spouses must establish a formal parental project;

• Parental project = agreement by which they formally consent to use the reproductive material of an outside person.

Role of the donor:

• The donor of reproductive material renounces all rights toward the child;

• Acts solely as a donor, cannot claim filiation;

• Filiation is established by birth certificate (as biological filiation) between the child and the persons who formed the parental project and/or continuous possession of status.

Parental project involving surrogacy (Surrogate mothers in Quebec):

• A parental project involving surrogacy is formed when a single person or spouses domiciled in Quebec have decided, in order to have a child, to use a woman or a person who is not a party to the parental project to give birth to that child;

• The parental project applies to all children resulting from it and cannot allow them to be separated (article 541.1 Civil Code);

• Even if the surrogate mother had agreed before birth to renounce filiation: renunciation has no legal effect.

The single person or spouses who formed the parental project must, before the planned pregnancy, enter into a surrogacy agreement with the woman or person who has agreed to give birth to the child.

Parentage is established in accordance with the parental project: the parents who consent to it become the child’s legal parents. The donor waives all parental rights.

Depending on your situation, the process aims to establish, recognize, or contest a paternity link. Each file follows a process tailored to the circumstances.

Generally, our support includes:

Step 1 – Initial consultation:

• Detailed explanation of the context and your objectives;

• Identification of the most appropriate course of action (voluntary acknowledgment, court application, contestation);

• Assessment of the file’s strengths and weaknesses.

Step 2 – Evidence gathering and paternity testing:

• Advice on whether a DNA test is appropriate to establish or contest parentage;

• Coordination with certified laboratories for reliable tests admissible as evidence;

• Management of situations where the alleged father refuses (available remedies, court order);

• Collection of relevant factual elements and witness statements.

Step 3 – Drafting and filing the proceedings:

• Drafting the application to the court (recognition, contestation, amendment of parentage);

• Strict compliance with deadlines and procedural requirements to avoid dismissal;

• Comprehensive preparation of the file with supporting documents.

Step 4 – Representation before the court:

• Presentation of legal arguments and evidence (paternity test, witness statements, context);

• Oral argument;

• The judge decides in the child’s best interests after considering all the evidence.

Step 5 – Judgment and follow-up:

• Effects of the judgment on parentage, civil status, child support, parental authority, and the child’s name;

• Updating official documents (birth certificate, civil status register);

• Adjustment of agreements regarding child support and custody, if applicable.

A lawyer helps avoid procedural errors that could cause the recognition or contestation of paternity to fail or be significantly delayed.

When is the ideal time to make a declaration of paternity?

The declaration may be made at birth or later, but acting promptly makes it easier to establish parental rights, child support, and the child’s legal stability.

A lawyer can guide you through the legal process, ensure the drafting and filing of necessary documents, coordinate DNA tests with a laboratory, and represent you before the courts to defend your rights and those of your child. They ensure compliance with procedures and deadlines.

Our services cover:

• Initial legal consultation to analyze your situation (presumed father, parent establishing paternity, challenge);

• Comprehensive explanation of the legal framework for paternity in Quebec;

• Assistance with DNA paternity testing (relevance, coordination with certified laboratories, probative value);

• Voluntary recognition of paternity (assistance with birth certificates, civil status documents);

• Court action to establish paternity when the link is contested or refused;

• Late declaration of paternity (support for fathers establishing filiation after the deadline, implications for the child’s rights);

• Contestation of presumed or declared paternity (representation, production of evidence, DNA testing, factual elements);

• Modification of filiation following a paternity judgment;

• Advice on impacts: child’s name, child support, parental authority, inheritance rights.

Personalized follow-up: Clear communication at every step, human support from our lawyers in this often emotionally charged context, protection of the child’s interests and the parent’s rights.

Continuous possession of status exists when a person is treated as a parent in practice. In Quebec, it creates a strong presumption of parentage and may prevent any subsequent challenge, except in exceptional circumstances.
