Yes. As long as you have the father's DNA to verify paternity, there is no minimum or maximum age for a paternity test.
You need not wait for birth for a paternity test. One can be done while the baby is still in utero (in the womb or inside its mother).
It all depends on if the test was done correctly
Absolutely! Its called a prenatal paternity test and it can be conducted after 8 weeks of pregnancy! This test can be done with the mother of the child and potential father of the child. This test is done with a simple blood test with the mother and a buccal test (cheek swab) with the potential father. Results are returned in 7 days from your lab. So, it is indeed possible to get a paternity test while you are pregnant.
The paternity test is done on both the father AND the child. Most, if not all, jurisdictions require a paternity test before awarding monthly child support payments. If that is the case where you live then you won't have a choice as it is usually done under court order. Your only option would be to never file for child support.
You can only "amend" a paternity affidavit if you have a paternity test done to prove or disprove paternity... In many cases this is something that the state will do (ie of child support orders)
It will have to be determined through a paternity test if the father is denying the child. If the father admits the child is his, no paternity test has to be completed.
If it becomes a matter of determining Child Support, yes, probably. It will be done by court order.
If you are a legal guardian of the child then you can take the child and go get a paternity test yourself.
you have to wait until the child is born and then about 250
A paternity test can determine if there is a parent-child relationship between two people. A paternity test would give genetic proof of that relationship.
The court can not order a paternity test after the child turns 18. The child is considered an adult at 18 years old.
