What Happens If Someone Refuses a DNA Test?

If a parent or relative will not take a DNA test, here is what your options may look like — from conversation to a court-ordered test.

Asking someone to take a DNA test can be emotional, and sometimes the answer is no. If a possible father, mother, or relative refuses, it can feel like you have run out of options. You usually have not.

Nobody can be tested without consent

DNA collection is always voluntary at the appointment. A collector will not take a sample from an adult who does not agree, and a child's sample requires consent from a parent or guardian with authority. That protects everyone involved.

Start with a conversation

Many refusals come from worry rather than defiance: fear of the result, concerns about privacy, or not understanding the process. It can help to explain that:

  • Collection is a simple cheek swab for most tests.
  • Results are confidential and shared only with the appropriate parties.
  • A non-legal test is for personal information, while a legal test is documented for official use.

Consider other relatives

When an alleged father is unavailable or unwilling, relationship testing with other family members may help. Depending on the situation, a laboratory may evaluate a grandparent, aunt or uncle, or sibling relationship instead. These tests evaluate likelihoods and may not answer every question, so ask us which participants the laboratory recommends.

Court-ordered genetic testing

If paternity matters for child support, custody, or inheritance, a court or child support agency can generally order genetic testing as part of a case. Refusing a court order can carry legal consequences, which vary by jurisdiction. A family law attorney or your local child support agency can explain the process where you live.

When a court or agency orders testing, it often specifies how collection must be done. Let us know the requirements and we can tell you whether our legal, chain-of-custody collection fits.
