Oklahoma Paternity Laws

When a married couple has a baby the state of Oklahoma automatically assumes the husband is the legal father. However, this presumption of paternity is not extended to unmarried couples. This means if an unmarried couple has a baby the biological father is not assumed to be the legal father unless the couple legally establishes paternity.

Challenging a voluntary acknowledgement of paternity in Oklahoma

When a child’s parents are unmarried, and the child’s mother has sole physical custody of the child, in general the child’s father may be ordered to pay child support. However, before a child support order can be executed, paternity must be determined. One way paternity is established in Oklahoma is if the father signs a voluntary acknowledgement of paternity form, either in the hospital or shortly thereafter. Such a form indicates that the father agrees he is in fact the child’s father. read more

The history of paternity tests: Blood typing

In general there are four different kinds of blood types – also known as antigens – that a person may have. These types are: O, AB, B and A. Whether a person’s blood type is negative or positive is not really necessary to identify for the purposes of a genetic test. The presence of these antigens could be found in a person’s red blood cells. Only certain combinations of antigens are genetically possible. For example, if a child has type AB blood, their father must have either type A or type B blood. While this test could not always prove with certainty who the father was, it could at least in some cases determine if a man could not possibly be the child’s biological father. read more

How is DNA testing used to establish paternity in Oklahoma?

One way for a father to establish paternity in Oklahoma is through genetic testing. In most of these cases, a test known as a Buccal Swab Specimen Collection will be used to gather DNA evidence. In this test, the inside of the man’s mouth will be swabbed, and then the samples will be sent to labs to be tested. Test results are 99.9 percent accurate. However, there may be some limited circumstances in which a blood test is necessary. Usually parents will receive the results of a genetic test via mail within six weeks of having the test done. read more
