Individuals in Florida can challenge paternity if they believe that the father of a child has not been named correctly. A challenge to paternity can be initiated by either parent.
There might be a number of reasons that a child's father might be incorrectly identified. While paternity tests that are administered correctly are typically very accurate, paternity tests can also be handled in a way that can lead to false results. For example, lab results could be tainted if the lab is doing substandard work. Paternity results can also be fraudulent, as in cases where the wrong person takes the paternity test. It is possible that results could be tampered with as well.
A woman's husband is often automatically presumed to be the father on a birth certificate, even if it is not proven that he is the biological father. This could lead to an individual challenging paternity.
Paternity is challenged by filing a complaint in court. DNA testing will then be used to determine who the father is. An individual may wish to do this if he believes he has fathered a child but the mother has named someone else as the father. The reason for doing so might be a desire to become involved with and responsible for the child.
An individual who is challenging paternity may wish to work with an attorney to do so as the process may be complex. If the individual is named as the father, there may be further child custody and support arrangements to work out, and having an attorney may be helpful at that stage.
