Establishing and Challenging Paternity - The Biological and the Legal Father Are Not Always the Same Person

In Georgia paternity arises in two ways: automatically, if the child is born in marriage (the husband is deemed the father even if he is not), and by acknowledgement or court order if there is no marriage. Both mechanisms generate disputes: a father who does not acknowledge the child; a husband who is not the biological father and pays maintenance; a biological father whose child is registered under someone else's surname; heirs who refuse to recognise an "unknown" child.

This page explains how paternity is established and challenged: the registry acknowledgement procedure and its consequences, court establishment and the role of DNA testing, what evading the test means, the deadline for challenging the marital presumption and why it is so strict, how paternity of a deceased man is established, and what happens with the child's registration, surname, citizenship and maintenance after establishment.

How Paternity Arises and Changes - Which Procedure Fits Which Situation

The procedure depends on the situation: whether the parents are married, whether the father consents, whether he is alive, and how much time has passed.

SituationProcedure
The child is born in marriage or within 10 months of divorceThe husband (former husband) is automatically deemed the father and the registry records him. Another man can be recorded only after the presumption is challenged, or by a joint application of all three.
The parents are not married and the father consentsA joint application at the registry, at the child's birth or at any time after; with the mother's consent, and for an adult child with the child's consent too. No court needed.
The father does not acknowledge or cannot be foundCourt establishment on a claim by the mother, the guardian or an adult child; DNA testing is the main evidence but not the only one: cohabitation, correspondence, care of the child, witnesses.
The father himself seeks establishment and the mother objectsA biological father has an independent right to court establishment; the mother's consent is not required. If the child is registered to another man, that paternity must be challenged first.
The registered father is not the biological fatherA challenge to paternity in court by the man recorded, the biological father, the mother or an adult child, within a strict period from the day the person learned of it.
The father has diedEstablishment of the fact of paternity in court, for inheritance, pension or surname; DNA from relatives (parents, siblings, other children) or preserved biological material; documentary and witness evidence.
What the lawyer does

Court Establishment of Paternity - From the Claim to the Registry Entry

  1. Defining the claimant and the claims

    Who is claiming (mother, father, child, guardian) and with which accompanying claims: maintenance, surname, contact arrangements, inheritance. The lawyer combines establishment and maintenance in one claim; maintenance is awarded from the date of establishment, not from a separate later filing.

  2. Gathering evidence before the test

    Evidence of cohabitation, the relationship and the period of conception: photos, correspondence, travel, mutual acquaintances, care during pregnancy, collecting the mother from the maternity ward, caring for the child. The court orders the test on the basis of this picture, and the picture becomes decisive if the test is evaded.

  3. The motion for DNA testing

    The court orders testing at a licensed institution; the cost is advanced by the claimant and ultimately borne by the losing party. A privately obtained test is evidence but does not replace the court-ordered one if the other side disputes it. The lawyer frames the motion so that sampling is not derailed by the respondent's absence.

  4. The consequences of evasion

    If the respondent fails to appear for testing or refuses to give a sample, the court is entitled to treat the disputed fact as established, that is, to find paternity without the test. The lawyer records every non-appearance in the minutes and asks the court for this outcome directly.

  5. Judgment and registration

    On the basis of the judgment the registry amends the birth record: the father's details, the surname (by agreement of the parents or by court decision), a new certificate. Maintenance and contact arrangements in the same judgment, if claimed.

  6. Consequences after establishment

    Established paternity operates retroactively from the date of birth: the right of inheritance, citizenship (in the case of a foreign father), the father's parental rights and duties. Taking the child abroad now also requires the father's consent; both sides should know this in advance.

Challenging

Challenging Paternity - Why the Deadline Is One Year and What "Learned" Means

Paternity recorded under the marital presumption, or registered by acknowledgement, can be challenged in court, but the law sets a one-year period from the day the person learned or should have learned that he is not the biological father. The period exists for the child's stability: a legal father who raised the child for years cannot shed paternity by "changing his mind", and a biological father who let years pass without proving anything cannot break up a family.

In practice the whole dispute turns on the word "learned". Suspicion and rumour are not knowledge; knowledge is a DNA result, an admission, or facts after which a reasonable person would have taken a test. The lawyer fixes the starting point of the period with documents: the date of the test, the correspondence in which doubt first appeared. The court allows restoration of the period for a valid reason, but rarely.

A challenge is not only a question of biological fact: a man who knew at the time of acknowledgement that he was not the father can no longer challenge the acknowledgement. And the child's interest weighs in a challenge too; despite an established biological fact, the court may decide maintenance and contact in the child's favour.

Numbers and consequences

Deadlines, Costs and What Establishing Paternity Changes

10 months
The period after divorce, annulment or the husband's death during which a child born is recorded as the former husband's. Recording a new partner as the father within this period requires overcoming the presumption.
1 year
The period for challenging paternity from the day of learning. After the child reaches majority, the child has their own right to challenge with their own period.
No limitation
Court establishment of paternity has no deadline: an adult child can bring it, and against a deceased father too. Maintenance, however, is awarded from the date of establishment, not retroactively.
Court fee 0
A claim concerning the child's rights is exempt from the fee. The cost of testing is advanced by the party requesting it and ultimately borne by the loser.
Retroactive effect
Established paternity operates from the date of birth: inheritance (if the estate has not yet been distributed or the period is still open), citizenship, surname. In an inheritance case the establishment claim must be planned together with the deadlines for accepting the estate.
Evidence

What to Collect for a Paternity Case - Besides the Test

  • Evidence of the relationship and cohabitation in the period of conception: dated photos, correspondence, joint travel, a lease.
  • Involvement during pregnancy and birth: doctor's visits, maternity hospital documents, payment of expenses, care of the child after birth.
  • Facts of acknowledgement: messages calling the child "mine", social media photos, gifts, relatives' statements.
  • In the case of a deceased father: relatives' consent to give samples, preserved biological material, medical archives, the deceased's handwriting and documents.
  • For a challenge: proof of when doubt arose and when knowledge came (the test date, correspondence), for counting the period.
  • In the case of a foreign father: his citizenship, country of residence and address, for service and the citizenship question.
Typical cases

Three Paternity Cases

A father who does not show up for the test

The mother sought establishment and maintenance; the respondent denied the relationship and failed to appear for testing three times. Lawyer: evidence of the relationship (correspondence, joint photos in the conception period, witnesses), minutes of each non-appearance, a motion to treat the fact as established. The court found paternity without a test and awarded maintenance.

A husband who learned after 6 years

After the divorce, the maintenance payer learned from a private test that he was not the father. Lawyer: a challenge filed within a month of the test, documentation of the moment of knowledge (the test date), a court-ordered test. Paternity was annulled and maintenance ended from the date of filing; past payments were not refunded.

A child claiming a deceased father's inheritance

A 30-year-old born outside marriage; the father had died and the heirs "did not know him". Lawyer: a claim to establish the fact of paternity for inheritance, DNA from the father's brother and another child (by court order), the father's letters and photos. Paternity was established and the child joined the circle of heirs.

Questions About Paternity

The child was born outside marriage and the father is nowhere to be found. Can I register the child under his surname?

Not without the father's acknowledgement or a court order: the registry records the father's details on the mother's statement, but that creates no legal paternity and the surname remains the mother's. The father's details and surname follow from establishment; the lawyer combines establishment and the change of surname in one claim.

I have a private laboratory DNA test. Is that enough?

It is admissible and often settles the matter before court, with the father acknowledging. But if the respondent disputes the test (origin of the sample, the laboratory), the court orders its own. The lawyer uses the private test as the basis of the claim and the court-ordered one as the final argument.

I am the biological father, but the mother registered the child to her husband. What rights do I have?

The right to challenge the husband's paternity, within a year of the day you learned, and then to establish your own; both in one claim. Testing with samples from all three. The child's interest is decisive, and if the child has a strong bond with the legal father, the court sets contact arrangements with that in mind.

The father is a foreigner living abroad. Where do I sue?

In a Georgian court, if the child or the mother lives in Georgia; service under international rules, and testing by the respondent giving a sample abroad or on arrival in Georgia. Establishing paternity gives the child a right to the father's citizenship under that country's law; the lawyer checks this as well.

Paternity has been established, and now I cannot take the child abroad without his consent. Is that fair?

An established father is a full parent with every consequence, maintenance and consents alike. On an unfounded refusal of consent the court itself grants permission based on the child's interests. Having the court set contact arrangements and a travel clause resolves this conflict in advance.
