Can a mother dispute her maternity and in what cases?

In accordance with the provisions of Art. 139 of the Family Code of Ukraine, a woman who is registered as the mother of a child can dispute her motherhood. A woman who considers herself the mother of a child has the right to sue the woman who is registered as the child's mother for recognition of her motherhood. Disputing maternity is not allowed in the cases provided for in parts two and three of Article 123 of this Code (in the case of transferring a human embryo conceived by a couple (man and woman) as a result of the use of assisted reproductive technologies into the body of another woman). The claim for recognition of maternity is subject to a one-year statute of limitations, which starts from the day the person learned or could have learned that she is the mother of the child.
