Legal Issues Connected to Paternity Disputes
Paternity issues and disputes are often serious because they can affect many different legal obligations. Disputes between mothers, fathers, and other legal guardians may involve:
- Child Support: Establishing paternity (whether legal or biological) can either impose or remove financial obligations towards child support for a father.
- Decision-Making Responsibility & Parenting Time: Formerly called custody and access, fathers may gain or lose their rights to children depending on the outcome of their paternity dispute.
- Inheritance Rights: Establishing paternity may impact succession and inheritance rights should a father pass away without a will.
- Immigration & Status: In some cases, establishing parentage may affect sponsorship or residency opportunities.
- And More
A Toronto paternity issue and dispute lawyer can advise all involved parties on their legal rights and obligations when disagreements arise. Whether you are seeking to prove biological relation to a child, or you are trying to argue for equitable father status, a legal professional can help.
Types of Paternity Disputes in Ontario
Paternity disputes usually occur when the identity of the biological father of a child is in question. Disputes may involve a variety of potential parents, including mothers, alleged fathers, or third parties (also called equitable fathers).
Paternity issues arise for a wide range of reasons, but they commonly occur when:
- Child support is sought from a father
- When a father seeks parenting time or decision-making responsibility
- When parentage is uncertain or challenged
- And more
In general, there are three main categories of paternity disputes:
Presumed Father Cases
These cases occur when a man is legally presumed father due to marriage, cohabitation, or acknowledgement. By definition, presumed fathers do not have to be biologically related to children in order to be considered a father. This is because Ontario courts take into consideration both biological and legal parenthood.
Presumed fathers may be ordered to pay child support or may apply for custody and/or access, depending on the circumstances.
Equitable Father Cases
These cases involve recognizing fathers who play a significant father-figure role in a child’s life but are not biological fathers. Equitable fathers may attempt to gain decision-making responsibilities or parenting time over their non-biological children. In Ontario, equitable fathers have limited recognition by the courts. However, it is possible for them to gain basic custody rights in certain cases.
Unwed Father Cases
In unwed father cases, fathers who are not married to the mother of the child must usually establish their biological relation to the child in order to secure custody rights. Although marriage does not affect biological parentage, being unmarried may make it more difficult for a father to gain custody over children.
What is the Presumption of Paternity in Ontario?
In some cases, the law makes a presumption of paternity. This means that a man will remain responsible for child support even if it has already been proven that the man is not the biological father of the child through a DNA test or blood test. This is because courts will also take into account a man’s conduct towards a child in order to determine whether he is an active parent.
In Ontario, the Children’s Law Reform Act (CLRA) may presume paternity when:
- The father was married to the mother at conception of the child, or within 300 days before the birth of the child
- The father and mother were cohabitating at the time of birth
- Acknowledgement exists (e.g., signing birth certificate, public representation as father)
- Court determination after DNA testing is positive
- And more
It is possible for presumption of paternity to be rebutted with DNA testing, but it is not always possible to erase child support obligations. For example, if a man has acted as a parent to a child for a significant period, their biological relationship to the child will not affect their legal responsibility towards the child.
