DNA Test - Westminster, California

Westminster CA DNA Testing Locations

Types of DNA Tests at our Westminster, California locations:

The most commonly ordered DNA test is a Paternity Test to conclusively establish whether or not a man is the biological father of a child.

Paternity Testing can be performed at our testing centers. DNA Testing can be done for other close family relationships, such as:

Grandparent DNA Test (if the father is not available for testing)
Sibling DNA Test (possible brothers, sisters, or half-siblings)
Avuncular DNA Test (aunt/uncle and niece/nephew)

Specimens we can test for DNA

The easiest and most reliable way to obtain a DNA sample for paternity testing is to swab the inner cheeks of the people being tested. These skin cells are known as buccal cells, and they rub off easily onto cotton swabs and remain in place for analysis by our laboratory. Other specimen samples, such as hair follicles, fingernails, and garments that might contain someone's DNA, can also be tested. An Alternative Specimen DNA Test is done by registering online and shipping the specimens to us.

Legally Admissible DNA Tests vs. "Peace of Mind" At-Home Tests

Our Westminster DNA testing technicians are trained to follow guidelines that ensure that the results can be used for legal purposes.

The Importance of Establishing Paternity in Westminster, CA

Under California family law, when a child is born to a married Westminster mother, the husband is automatically presumed to be the biological father, granting him paternal rights over the child. However, when two Westminster parents are not married at the time of birth, paternity will need to be properly established to legally declare the biological father and for him to receive parental rights.

The paternity establishment process is a legally binding step in creating a state-recognized relationship between a biological father and child. This process also helps better preserve the well-being of a child, as he or she can now receive benefits from both parental parties. Due to the legally binding nature of paternity establishment, it's important for Westminster parents to first verify paternity presumptions with the use of DNA testing before moving forward.

Methods of Establishing Paternity in Westminster, CA

Once DNA testing services have been used to properly identify a child's biological father, two Westminster parents can now establish paternity. Orange County provides two methods of establishing paternity, one being the completion of a Declaration of Paternity form. Both parents must sign and complete this form, either at the hospital following the child's birth or through an Orange County Child Support Services location, to establish paternity.

If a parent refuses to establish paternity on the basis of paternity denial or general refusal, you will need to use the second method of establishing paternity by filing a petition in court. Through Orange County Family Court, a petition to establish a parental relationship can be made allowing the court system to seek DNA testing from the presumed father. If the court system can verify the child's biological father, paternity can be established as well as a child support agreement.

Experts in Westminster, CA Say…

Establishing paternity in Westminster is not only important for providing the biological father with parental rights, but according to Westminster family law attorney David Goldberg, it is also beneficial for the wellbeing of a child. By establishing paternity, children are also given access to their father's medical history, as well as benefits including inheritance, social security, and even veteran benefits when available.
