◎Prenatal Paternity Tests Worries about family relationship tests


◯The father won`t recognize the child as his.

  • Prenatal Paternity Tests
  • Relationship DNA Tests

If the man you have had relations with does not recognize your child as his, you can turn to DNA testing.In cases of the `300 days after divorce` problem, it can be difficult to get the ex-husband to participate in a DNA test. Up until a few years ago, unsuccessful cases where mediation ended in failure, or the mother simply gave up were common. However, in recent years the problem of the ex-husband`s unwillingness to cooperate has been taken into consideration. There have been cases where family court has determined the ex-husband`s cooperation as difficult, and ruled in favor of the man confirmed as the actual father with DNA test evidence.

◯I want to know if the unborn baby (or already born child) is mine.

  • Prenatal Paternity Tests
  • Relationship DNA Tests

If you have doubts whether a child is yours, you can find the answer through DNA testing. If the mother is still pregnant, it is possible to have a prenatal paternity test. If the child has already been born and a father registered, in order to have the paternity negated (denial of legitimacy) the husband can file with family court. Even in situations where the requirements for filing for negation do not seem to be fulfilled (such as no action having been taken in 1 year since the birth of the child) there have been cases where paternity was successfully negated.

◯I want to confirm the blood relationship of a child that was born within the 300 day period following a divorce.

  • Prenatal Paternity Tests
  • Relationship Tests

The `300 days after divorce` problem refers to the Civil Code provision in Japan that regards a baby born within 300 days after the mother`s divorce as a child born to her former husband.

Article 772 of the Civil Code states that if a child is born within the 300 day period following a divorce, the child is to be registered as the child of the former husband, and it is presumed that the child was a product of the married couple. Even if the mother has remarried, and the new husband is the actual father, the child cannot be registered as his child. Awareness of the 300 day after divorce issue has been spreading thanks to television and news coverage, and it was even a main theme in a television drama series. At seeDNA, many of the consultations we receive are from people dealing with this problem.

◯My child`s birth was not registered, and now I cannot register my child. (Unregistered children problem)

  • Relationship DNA Tests

When a child is born, if there are issues between the parents and the birth is not registered, in the future the child can face a variety of problems. The child can have trouble attending school (although it may be possible that a student ID be issued by a school), getting a driver`s license, getting married or other various obstacles. A DNA test is required is necessary when making a motion to the court to acquire a family register. A maternity test done with the mother and the unregistered child can prove the biological parent-child relationship, and the possibility of being allowed to add the child to her family register is increased greatly.

In cases where the mother wants to have a paternity test done, but the alleged father is not available (deceased, missing, or other reasons), it is possible to test the alleged father`s parents and the child in a grandparentage test.

  • Sibling DNA Tests

A DNA test can confirm if tested individuals are biologically brothers or sisters.
For example, take a situation where a father has died, and it is later revealed there is a chance one of his registered children may not actually be his. The siblings can have a sibling DNA test done to find out if they are actually related.Siblings that have the same mother, but want to find out if they also share the same father, can have a full-siblingship test done.
Or, two individuals that have different mothers, but suspect that they share the same father, can have a half-siblingship test done. For this type of test it is best to provide samples from the mothers as well. (testing fees do not change)

  • Sibling DNA Tests

DNA testing can be used to provide proof of entitlement to an inheritance. There are various relationship DNA tests that can be done (grandparentage test, sibling DNA test, paternity tests, etc) that can be done to determine the biological relationship between the tested individual and the deceased. If an aunt and uncle test, it is necessary to provide specimens of at least 4 people, and for sibling DNA tests there must be at least 2 participants.

◯I am divorced and need help with child support.

  • Relationship DNA Tests

The usage of DNA tests as leverage in a child support case can differ depending on the position of the divorcees. If the application for a test comes from the former husband, he can want to confirm for sure that the child he is paying for (or being asked to pay for) is indeed his biological child.
If the former wife is asking for the test, it is usually the case that the former husband and father is not making his child support payments and she wants to prove his obligation as the biological father.
We offer both personal DNA tests and legal DNA tests. If the conflict can be resolved between the former husband and wife through discussion, then a personal DNA test can be done. If the conflict will be taken to court to be resolved, then a legal DNA test would be required.

The AKC (American Kennel Club) reported that 10% of the information listed in the register is erroneous. A canine DNA test will provide undebatable proof that a dog is from a purebred line.

The American Kennel Club was founded in the US in 1884, and oversees the census management of all pureblood dogs.
