Parentage in Quebec

Share this article

Parentage is a legal principle established to recognize the family ties between a child and their parents. It establishes both patrimonial and extrapatrimonial legal ties between parents and their children. Indeed, parentage is a crucial aspect of family law, as it influences numerous legal issues, which will be examined in detail in this article.

Establishment of Parentage

In Quebec law, parentage is primarily divided into three categories: parentage by blood or recognition, parentage by adoption, and parentage by assisted procreation. It is important to note, however, that despite their differences, children benefit from the same rights and obligations, regardless of the nature of their parentage with their parents. [1]

Parentage by Blood or Recognition

By birth certificate: For the mother, giving birth to the child automatically establishes a blood parentage link between her and the child.[2] For the father, this parentage link is recognized when both parents jointly declare it on the child’s birth certificate.[3]

By presumption of paternity: In the event of a child’s birth within a marriage, civil union, or de facto union, the child is presumed to have the mother’s spouse as the other parent.[4]

By constant possession of status: Parentage by constant possession of status is established when a sufficient set of facts demonstrates parentage ties between the child and the person acting as their parent. Concretely, for constant possession to exist, the parent must act and be known as the true parent from the child’s birth, for a minimum period of 24 months. [5]

However, numerous legal mechanisms exist to contest or disavow parentage. It is important to note that each situation is unique and requires a thorough analysis of its specific facts. Therefore, it is essential to consult a lawyer or qualified professional who can assess your case and guide you through the necessary steps to initiate a contestation. Legal expertise is indispensable to ensure your rights are protected and procedures are followed correctly.

Parentage by Adoption

While being a child protection mechanism, adoption is another method of establishing parentage. Adoption can be voluntarily consented to by biological parents or ordered by the court in certain circumstances[6], such as abandonment or forfeiture of parental authority. In all situations, the primary and determining criterion for authorizing a child’s adoption is always their best interest.[7] It is important to note that one must be of legal age to adopt a child[8] and that the adopter must be at least 18 years older than the adopted person, unless the latter is their spouse’s child.[9]

Parentage by Assisted Procreation

Assisted procreation encompasses all techniques that allow individuals experiencing difficulties conceiving a child to realize their parental project. These techniques are used to treat infertility problems or to enable same-sex couples or single individuals to have a child.

In cases where assisted procreation involves the use of third-party reproductive material, the single person or the spouses must first establish a parental project. This parental project is an agreement by which they consent to use reproductive material from a person outside the parental project.[10] The donor of reproductive material must waive all rights to the child and act solely as a donor, consciously and voluntarily. Consequently, this donor cannot claim parentage with respect to the child. [11]

Regarding assisted procreation carried out by a surrogate mother, even if the surrogate mother had agreed, before birth, to waive all parentage ties with the child, this waiver would have no legal effect.[12] Thus, the surrogate mother retains the right to decide to keep the child and be recognized as the legal mother. This is why it is crucial to be well-prepared, choose trustworthy individuals, and surround yourself with competent professionals to manage the legal and emotional aspects of assisted procreation by surrogacy in Quebec.

Legal Effects of Parentage

The effects of parentage are numerous and affect various aspects of family law. Here are the main effects of parentage between parents and their children:

Family Name

The child takes the family name of their parents, or a combination of each parent’s family names.

Nationality and Citizenship

Parentage can influence the child’s nationality and citizenship, especially if the parents are of different nationalities.

Support Obligations

Parents have an obligation to provide for their child’s needs, which includes housing, food, clothing, medical care, and education.

Parental authority

Parents have the right and duty to make decisions regarding their child’s education, health, and well-being until they reach majority or are emancipated. Parental authority includes aspects such as custody, supervision, maintenance, and education of the child.

Inheritance Rights

The child has inheritance rights over their parents’ property. In the event of the death of either parent without a will, the child automatically has a right to a share of the estate under the rules of legal devolution.

Conclusion

Parentage in Quebec law is a complex but essential area that ensures the recognition and protection of family ties. It establishes fundamental rights and obligations for parents and children and plays a crucial role in the legal structuring of family relationships.
