how to establish paternity without a dna test

Wanting to know if a child is yours is a common thought by many alleged fathers, friends, family members and even from the child’s mother in some cases. In this post, we will discuss some ways people over the years have attempted to determine paternity.

What is the most accurate way to determine paternity?

Performing a DNA test to determine paternity is currently the most accurate method of determining paternity. This option is also the only option today the court will accept to help establish paternity. Here are some of the most common ways people attempt to determine paternity without a DNA test:


blood types

1. Blood typing:

One of the ways some people have attempted to determine who the father of a child is by way of comparing the blood types of the alleged father with the child. Although you may be able to exclude an alleged father by using this method. Determining paternity using this method is not as effective. For example, If two men are possible fathers of a child and they are both “A” blood types. It would be difficult to determine who is actually the biological father of the child. Now, if one of the men is blood type “B”, the other man is blood type “A” and the child is blood type A. This is assuming there are only two candidates that may be the biological father of the child. The likelihood of the man with blood type “A” being the biological father would be more certain. It is important to note that this option is seldom used in family court by judges.

colored eye

2. Eye Color:

Another way many people have attempted to determine paternity is by looking at the eye color of the child. This option is less effective than the previous options because if the mother and father have brown eyes and the child has green eyes. The child’s eye color could have inherited this recessive gene trait from a family member from either the mother or father’s bloodline. This option is not an acceptable option to establish paternity through family court.

baby face features

3. Facial features (Phenotype):

This option is the commonly used option by many people when attempting to determine paternity. If the child looks like the alleged father it is often looked upon as a no-brainer that the father is biologically related to the child. This is not always the case. If a mother had multiple partners who shared similar features. It would confuse things in terms of who the biological father of the child may be. Remember, facial features would not be an acceptable option to determine the paternity of a child for legal purposes.

conception date

4. Date of possible conception:

This method is another popular method used to help with determining the paternity of a child. It could potentially work if the mother had intercourse with two different men weeks apart. If the mother had intercourse a couple of days apart with both men. Then calculating who the possible father is, becomes extremely difficult to do. It is important to remember this option is not a definitive option and can not be used as evidence for any legal purpose.
