If a man died without being married to the child's mother, paternity is established by a court — usually not through a lawsuit, but through a petition in special (non-adversarial) proceedings under Article 130 of the Family Code of Ukraine. The key condition: the father's name in the civil status record must have been entered based on the mother's statement. The main risk is not the evidence but a procedural trap: if the court sees a "dispute over a right" in the case, the petition will be left without consideration. Below is how this risk is addressed, when it is better to sue the heirs straight away, which evidence works, and what a court decision gives you for inheritance and payments.
In brief: 6 points
- After a husband's death, paternity is established by a petition in special proceedings (Article 130 of the Family Code of Ukraine), not by a lawsuit for recognition of paternity.
- A precondition without which the court will not accept the petition: the father's name was entered at the mother's direction (Part 1, Article 135 of the Family Code).
- The law does not set a fixed list of evidence. A forensic molecular-genetic (DNA) examination is the strongest evidence, but not the only one.
- The most common reason for losing such a case is not weak evidence but a dispute over a right: under Part 4, Article 315 of the Civil Procedure Code (CPC) of Ukraine, the court leaves the petition without consideration if such a dispute is found.
- If a dispute over a right is obvious — the deceased has other heirs or there are other claimants to payments — you file a lawsuit against the heirs in claim proceedings. That is what I did in case No. 712/6431/26.
- A court decision opens the child's right to have the civil status record amended, and to inherit and receive payments connected with the father's death.
Recognition of paternity vs. establishing the fact of paternity: two different mechanisms
These are two different procedures, and the choice between them determines not just tactics but the outcome of the case itself. A mistake here costs several months and the court fee.
| Feature | Recognition of paternity | Establishing the fact of paternity |
|---|---|---|
| Legal basis | Articles 128, 129 of the Family Code | Article 130 of the Family Code |
| Father | alive | deceased |
| Form of application | statement of claim | petition |
| Type of proceedings | adversarial (claim) proceedings | special (non-adversarial) proceedings |
| Parties | claimant and defendant | petitioner and interested parties |
The fact that paternity was never decided in court during the husband's lifetime does not prevent applying Article 130 of the Family Code after his death. This follows directly from current Supreme Court of Ukraine case law that courts rely on in such cases — in particular, the rulings of 13 September 2023 in case No. 552/4291/22 and of 31 January 2024 in case No. 752/13549/22.
The table describes the typical situation. There is a third scenario: the man has died, but there is a dispute over a right between the child and his heirs — over the inheritance or payments. The case is then heard in claim proceedings, and the deceased's heirs are the defendants. That is how my case No. 712/6431/26, described below, was heard.
Mandatory precondition: the father's name entered based on the mother's statement
A petition to establish the fact of paternity is accepted by the court only when the father's name in the Register of Births was entered in accordance with Part 1, Article 135 of the Family Code of Ukraine. This applies when the mother is not married, there is no joint statement from both parents, and there is no court decision: in that case the child's surname is recorded after the mother's surname, while the father's first name and patronymic are entered at the mother's direction.
Practical consequence: the first thing to check before going to court is an extract from the State Register of Civil Status Acts regarding the child's birth, showing the basis on which the information about the father was entered. If the entry was made on a different basis, the Article 130 mechanism does not apply and a different strategy is needed.
Why a petition, not a lawsuit: special proceedings
Special (non-adversarial) proceedings are a type of non-claim judicial procedure in which the court confirms the presence or absence of legal facts (Part 1, Article 293 of the CPC of Ukraine). A deceased person cannot be a defendant, so where there is no dispute the "claimant vs. defendant" structure is not needed here. If there is a dispute over a right, the deceased's heirs become the defendants.
The petition may be filed by the mother, the child's guardian or custodian, a person who supports and raises the child, or the child personally after reaching the age of majority. The civil registry office (DRACS) and other persons whose rights are affected by the case are involved as interested parties.
The list of facts in Article 315 of the CPC is not exhaustive. The court establishes a fact if it gives rise to legal consequences, the law provides for no other way to establish it, the petitioner cannot obtain the relevant document by any other means — and establishing the fact is not connected with the subsequent resolution of a dispute over a right.
The main trap: a "dispute over a right"
This is where such cases most often fall apart. Under Part 4, Article 315 of the CPC, a judge refuses to open proceedings if a dispute over a right is already apparent from the petition, and if such a dispute is discovered during the hearing, the judge leaves the petition without consideration (Part 6, Article 294 of the CPC) and explains the right to file a lawsuit on general grounds.
The most common argument against the petitioner goes like this: establishing paternity will give the child a right to inherit or to receive payments that another relative already receives — therefore, this is a property claim, therefore it is a dispute over a right, therefore the petition must be left without consideration.
This argument does not automatically succeed. The key distinction that has to be explained to the court is that a dispute over a fact is resolved in special proceedings, and the mere prospect that the established fact will later be used to exercise property rights does not, by itself, turn the case into a dispute over a civil right. Likewise, an interested party's disagreement with the petition does not by itself create a dispute over a right.
There is another way to remove this risk — not waiting for the petition to be left without consideration. If a dispute over a right is obvious before going to court, I file a lawsuit against the deceased's heirs straight away. The procedure is longer, but the argument about the wrong type of proceedings simply falls away.
When special proceedings will not work
There is one situation worth knowing in advance, so as not to waste months for nothing. If the man is missing and there is no court decision declaring him deceased, the fact of paternity cannot be established through special proceedings — this is the position of the Civil Cassation Court within the Supreme Court of Ukraine. A person must first be declared deceased, and only then can a petition to establish the fact of paternity be filed.
Evidence: DNA and what works alongside it
The law does not set a specific list of evidence for establishing the fact of paternity. The basis may be any information confirming the child's descent from a particular person, gathered in accordance with civil procedure legislation.
A forensic molecular-genetic (DNA) examination is the strongest evidence. After the man's death it is still possible if his biological sample has been preserved or samples from close relatives are available. A sample may be kept in the archive of the forensic medical bureau that examined the body — this is found out through an attorney's request. The examination can also be carried out before going to court, under a contract with the expert institution. The European Court of Human Rights, in its case law, recognises the DNA test as a method whose evidentiary value substantially outweighs other evidence in cases concerning a child's descent.
Along with the expert opinion, the court also assesses:
- evidence of living together and running a shared household;
- witness testimony — from relatives, neighbours, or colleagues from service or work;
- messenger correspondence, joint photos and videos;
- money transfers for the support of the mother and child;
- public acknowledgment of the child as his own during the man's lifetime;
- documents in which the man named the child or the child's mother.
Importantly, none of this evidence is decisive on its own. The court assesses it as a whole — the relevance, admissibility and reliability of each piece, and the sufficiency and interconnection of the evidence taken together (Article 89 of the CPC of Ukraine). That is why I assess a case that relies only on witnesses, with no documentary support at all, as risky, and I tell the client that upfront.
Documents: what to get, where, and why
| Document | Where to obtain it | Why it is needed |
|---|---|---|
| Child's birth certificate | Civil registry office (DRACS) / the "Diia" app | Confirms the existing information about the father |
| Birth extract from the DRACS showing the basis of the entry | DRACS civil registry office | Key document: confirms the entry was made under Part 1, Article 135 of the Family Code |
| The man's death certificate or a decision declaring him deceased | DRACS / court | Without it, Article 130 of the Family Code does not apply |
| Certificate on the circumstances of death | The body where he served or worked, or a medical institution | Needed for further payments and for the completeness of the evidence |
| Materials for the genetic examination | Motion to the court to order the examination, or an attorney's request to the forensic medical bureau and a contract for the examination | Primary evidence of the child's descent |
| Evidence of the relationship: photos, correspondence, transfers | Personal archive, bank statements | Confirm shared life and acknowledgment of the child |
| Data on interested parties | Family documents | The correct circle of participants is a condition for the decision's validity |
My case No. 619/866/24: what the appeal challenged
I represented the child's mother in a case to establish the fact of paternity of a man who died in February 2023. The child was born after his death, in August 2023, and the father's name was entered based on the mother's statement.
The first-instance court granted the petition: it established the fact of paternity and ordered amendments to the birth record — information about the father, the father's citizenship, and the child's surname. One piece of evidence was a forensic molecular-genetic examination opinion with a probability of paternity of no less than 99.9999999959101%.
An appeal was filed by an interested party — the deceased man's mother, through her lawyer. Her key arguments were procedural, not factual:
- the case could not be heard in special proceedings at all, because the actual purpose of the petition was to obtain a payment already awarded to another person, which meant there was a dispute over a right;
- the expert opinion was incomplete and drawn up with violations: the examination was initially assigned to one expert but was in fact carried out by another, without any explanation for the reassignment, and with questions about that expert's experience in the relevant field.
The appellate court rejected these arguments: the first-instance court's decision was left unchanged, and the appeal was dismissed. The ruling was issued on 24 February 2026 in case No. 619/866/24, proceedings No. 22-ц/818/492/26.
The circumstances of the case are presented anonymised. The text of the court decision is public and available in the Unified State Register of Court Decisions under the case number.
What I took away from this case in practical terms: you need to prepare not for a dispute over the evidence, but for a dispute over the type of proceedings. When the deceased man is survived by a relative who is already receiving payments, the "this is a dispute over a right" argument will almost certainly come up. The response to it is prepared in advance — already at the stage of drafting the petition's relief sought. And separately: it is worth checking the procedural history of how the examination was assigned right away, because that is exactly what the opposing side tends to latch onto.
This is the outcome of one specific case with a specific set of evidence. It is not a promise of the same outcome in a different case.
My case No. 712/6431/26: a lawsuit against the heirs and DNA from a forensic archive
In this case I represented an adult son. In his birth certificate the father's name was entered based on the mother's statement. His biological father, a serviceman, was killed in February 2024 in a combat zone; paternity was never acknowledged or registered during his lifetime. The son learned of his death only in spring 2026, from a publication on a city council website.
How we obtained the DNA. In reply to an attorney's request, the forensic medical bureau reported that its archive held biological material of the deceased suitable for a molecular-genetic examination. The client signed a contract with the bureau and paid for the examination — UAH 20,535.62. The expert opinion was ready in under two weeks: the probability of paternity is no less than 99.99999%. We went to court with the opinion already in hand.
Why a lawsuit, not a petition. The deceased is survived by a wife and a daughter, and the documents for the one-time financial assistance payable on his death were already under review at the Ministry of Defence. A dispute over a right was obvious, so in May 2026 I filed a lawsuit against the heirs; the civil registry office (DRACS) and the Ministry of Defence took part as third parties. The court heard the case in general claim proceedings.
The objections. The Ministry of Defence asked the court to dismiss the claim: in its view, the claimant had to prove that the deceased acknowledged him as his son during his lifetime, had not identified the circle of heirs, and in any event had no right to the one-time financial assistance. The representative of the deceased's daughter left the matter to the court's discretion.
The outcome. By its decision of 5 October 2026, the Sosnivskyi District Court of Cherkasy granted the claim: it recognised the deceased's paternity of the claimant and ordered the birth record amended to name him in the "father" field. The court proceeded from the rule that any information on the child's descent may serve as the basis (Article 128 of the Family Code of Ukraine; Supreme Court ruling of 21 February 2020 in case No. 643/9245/18) and relied on the expert opinion. The court did not decide the question of entitlement to payments in this case.
This is a first-instance decision. As of the date this article was updated it has not entered into legal force: there are thirty days to appeal. The circumstances of the case are presented anonymised.
What to take from this case: find out before going to court whether biological material has been preserved, and do not be afraid of claim proceedings where a dispute over a right is unavoidable. Less than four months passed from the opening of proceedings to the decision.
This is the outcome of one specific case with a specific set of evidence. It is not a promise of the same outcome in a different case.
What a court decision gives you: inheritance, payments, the civil status record
A decision establishing the fact of paternity is not a formality. It opens up:
- amendments to the birth record: information about the father, the father's citizenship, and, if needed, the child's surname;
- the right to inherit from the father under the law;
- the right to payments connected with the father's death, and to a survivor's pension — the exact list and amount depend on the father's status and the cause of death, so they need to be checked separately for each case;
- confirmation of the child's origin, which concerns the child's private life within the meaning of Article 8 of the Convention for the Protection of Human Rights and Fundamental Freedoms.
A decision on paternity does not itself award any payments. In case No. 712/6431/26 the Ministry of Defence insisted that an adult son has no right to the one-time financial assistance — that question is decided separately, after the birth record has been amended.
The operative part of the decision must contain all the information needed to register the paternity with the civil registry office (DRACS). If the wording is incomplete, the DRACS will not be able to make the amendments, and you will have to go back to court. This is something worth checking already at the stage of preparing the petition.
Time limits, risks and common mistakes
- There is no limitation period for establishing the fact of paternity. But delay harms the evidence: witnesses move away, correspondence is lost, and biological samples become unavailable.
- Choosing the wrong type of proceedings. No dispute over a right — a petition in special proceedings; there are heirs or claimants to payments — a lawsuit against them. A mistake in either direction leads to lost time.
- Not verifying the basis for the father's entry. If the entry was not made under Part 1, Article 135 of the Family Code, the Article 130 mechanism does not apply.
- An incomplete circle of interested parties. This is a direct route to having the decision overturned.
- Relying on DNA alone. The examination can be challenged on procedural grounds — and then it is the circumstantial evidence that holds the case together.
- A vague operative part. The DRACS enforces the decision literally.
What to do now
- Order a birth extract from the DRACS for the child and check the basis for the father's entry.
- Obtain the death certificate, or check whether the man first needs to be declared deceased.
- Gather evidence of the relationship: photos, correspondence, transfers, and witness contacts.
- Find out whether biological material has been preserved (including by a request to the forensic medical bureau) and which relatives could provide samples.
- Identify the circle of interested parties and assess the risk of the "dispute over a right" argument; if the dispute is obvious, prepare a lawsuit against the heirs.
- Prepare a petition or a lawsuit with relief sought that the DRACS can actually enforce.

Frequently asked questions
Can paternity be established without a DNA examination?
Yes. The law does not set a fixed list of evidence, and the court assesses it as a whole. Without an examination the case is harder, and the weight of circumstantial evidence — shared living, testimony, correspondence, transfers — increases. But promising a result in such a case in advance is not possible.
How long does a case to establish the fact of paternity take?
The timeline depends on whether a genetic examination is ordered and whether interested parties file an appeal. The examination alone adds several months. Naming a universal timeframe would not be honest. As a reference point: in case No. 712/6431/26 the examination was done before going to court, the lawsuit was filed in May 2026, and the first-instance decision was issued on 5 October 2026.
What happens if the court leaves the petition without consideration due to a dispute over a right?
In that case the court explains the right to file a lawsuit on general grounds. This does not close off the path to protecting your rights, but it changes the procedure, the circle of participants, and the subject of proof. It is better to anticipate this risk before filing the documents: if the dispute is obvious, you can sue the heirs straight away — as in case No. 712/6431/26.
Can paternity be established if the father is missing?
Without a court decision declaring the person deceased — no, not through special proceedings. The person must first be declared deceased, and only then can a petition to establish the fact of paternity be filed.
Who else, besides the mother, can file the petition?
The child's guardian or custodian, a person who supports and raises the child, and the child personally once they reach the age of majority. In case No. 712/6431/26 it was the adult son who went to court.
Is the consent of the deceased's relatives required?
No consent is required. Relatives may take part as interested parties and object to the petition, but their disagreement alone is not an obstacle to establishing the fact.
Do I have to prove that the father acknowledged the child during his lifetime?
No, if the child's descent is confirmed by other evidence. The basis may be any information confirming the child's descent from a particular person. In case No. 712/6431/26 the Ministry of Defence insisted on evidence of lifetime acknowledgment, but the court granted the claim on the basis of the molecular-genetic expert opinion.
