Establishing Cohabitation with the Deceased for Inheritance: When It's Needed

You lived with the deceased in the same apartment for years, cared for them, arranged the funeral — and the notary says you never accepted the inheritance and the deadline has passed. Or the opposite: you are sure you have the right to inherit as a family member, but you are told you are not an heir at all. Both situations are resolved by establishing a fact in court, but the facts are different, the order of inheritance priority is different, and the type of proceedings is different too. Confusing them is the main reason such applications get left without consideration.

In brief: 6 points

• An heir who permanently lived with the deceased at the time the inheritance opened is deemed to have accepted it — no separate application to a notary is needed.
• This is not the same as living together as a family for at least five years, which gives the right to inherit as a fourth-priority heir under Article 1264 of the Civil Code of Ukraine.
• Registered place of residence does not settle everything. What matters is actual residence; the registration is only one piece of evidence.
• The fact of a man and a woman living together as a family without marriage is not, on its own, established in special (non-contentious) proceedings, unless it creates legal consequences for the applicant.
• If there is a dispute over a right, the application will be left without consideration and a lawsuit will have to be filed instead.
• The main evidence is documents, not words: joint utility payments, medical call-outs, certificates, correspondence, witnesses.

Two different facts that keep getting confused

This is the core of the whole topic. Which fact you actually need determines the legal provision, the order of inheritance priority, and the type of proceedings.

The practical conclusion is simple. If you are a child, wife, husband, or another statutory heir and lived together with the deceased, you need the first fact, and the question of priority order does not even arise. If you were living together without marriage and there are no first-, second-, or third-priority heirs, you need the second fact, and here the key number is five years.

Why cohabitation counts as accepting the inheritance

The law follows simple logic: a person who lived with the deceased and, after their death, continues to use the same home and belongings has effectively already taken possession of the inheritance. Requiring a separate application from that person as well would be excessive formalism.

That is why an heir who permanently lived together with the deceased at the time the inheritance opened is deemed to have accepted the inheritance, unless they filed an application renouncing it within six months. This applies even when that person never contacted a notary and did not know the inheritance had opened at all.

This is exactly why people who missed the six-month deadline should first check the fact of cohabitation, not the grounds for an additional deadline. If cohabitation is established, there is no need at all to ask a court for an additional deadline to accept the inheritance: the inheritance has already been accepted by operation of law.

A temporary absence does not break cohabitation

A question that comes up in almost every such case. Permanent cohabitation does not mean the person never physically left the apartment.

An heir is deemed to have permanently lived with the deceased even where, for some period before the death, they were away for a valid reason — for example, on a long business trip or receiving medical treatment — and returned only after the deadline to accept the inheritance had already passed. What matters is not uninterrupted physical presence, but an established way of life and the intention to actually live there.

When special (non-contentious) proceedings will not work

This is where the main procedural trap lies. Courts hold that special proceedings can only establish facts that, on their own, create legal consequences for the applicant and are not connected with resolving an underlying dispute over a right.

In case No. 686/19661/20, the Supreme Court concluded that establishing the fact of a man and a woman living together as a family without a registered marriage does not, on its own, create legal consequences, and therefore that fact cannot be established in special proceedings. By contrast, the fact of permanent cohabitation with the deceased at the time the inheritance opened can be established — when it genuinely protects a specific inheritance right of the applicant.

If there is already a conflict over the property between you and the other heirs, an application in special proceedings will most likely be left without consideration because of the dispute over a right. In that case a lawsuit is needed, and it is better to prepare it from the start than to spend months on an application that will not be decided on the merits.

What proves the fact of cohabitation

The most common mistake is coming to court with nothing but a certificate of registered residence. Registration does not prove actual residence, and its absence does not disprove it either. The court weighs the evidence as a whole:

• a certificate of family composition or information about registered residents;
• utility bill receipts issued in your name or paid by you;
• service contracts concluded at that address;
• medical documents: doctor call-out records, a medical chart with the address, documents about caring for the deceased;
• correspondence, bank and postal documents showing the same address;
• witness testimony — neighbors, the local district doctor, staff of the homeowners' association (OSBB);
• documents related to the funeral and its expenses;
• joint photos, correspondence — supporting evidence.

For the fact of living together as a family, you additionally have to prove a shared household, mutual rights and obligations, and running a joint household — and all of this for at least five years before the day of death.

Who takes part in the case

In an application filed in special proceedings, you are the applicant. The interested parties brought into the case are those whose rights the case affects: the other heirs, the notary handling the inheritance case, and, where necessary, a local self-government body.

Getting the list of participants right matters in practice: if an interested party is not brought into the case, the ruling can later be overturned, and the whole process will have to be repeated.

Documents: what to get, where, and why

If you do not have the documents on hand and they have been lost, you will first need to restore the documents and obtain extracts from the civil registry office (DRACS).

Action plan

1. Determine which fact you need: permanent cohabitation with the deceased, or living together as a family for at least five years.
2. Order an extract from the Inheritance Register and find out whether an inheritance case has been opened and who has filed applications.
3. Apply to a notary and obtain a written ruling stating the reasons for the refusal.
4. Assess the risk of a dispute over a right: if the other heirs object, prepare a lawsuit, not an application.
5. Gather evidence of cohabitation — at least three independent sources, not just registration.
6. File either an application in special proceedings or a lawsuit, depending on whether there is a dispute.
7. After the ruling, return to the notary to formalize your inheritance rights.

Mistakes that cost people their inheritance

• Confusing the two different facts. This determines the legal provision, the priority order, and the type of proceedings.
• Relying only on registration. Registration alone does not prove residence.
• Filing in special proceedings when there is already an open conflict. The application will be left without consideration.
• Failing to bring in all interested parties. The ruling can be overturned.
• Forgetting about the five-year requirement in cases about living together as a family.
• Delaying. Witnesses move away, receipts do not get kept, and medical records are destroyed once their retention period expires.

Frequently asked questions

I lived with the deceased but never filed an application with a notary. Is the inheritance lost?

Not necessarily. The law provides that an heir who permanently lived together with the deceased at the time the inheritance opened is deemed to have accepted the inheritance, unless they filed an application renouncing it within six months. In other words, no separate application to accept is needed in that case: the inheritance is deemed accepted by operation of law. The rule applies even when the person never contacted a notary and did not know the inheritance had opened. The problem arises at the formalization stage: the notary requires documentary proof of the fact of cohabitation, and if the documents are insufficient, that fact has to be established in court. So the first step should not be a lawsuit for an additional deadline, but checking whether you have evidence of cohabitation on the day the deceased died. This fundamentally changes both what you ask the court for and the list of documents you need to gather.

Is being registered at the deceased's address enough?

No, registration of residence alone is not enough, and this is one of the most common mistakes. The court assesses actual residence, and registration is only one piece of evidence that can be rebutted by other circumstances. The reverse also holds: the absence of registration does not mean the person did not live there, if that is confirmed by a body of other evidence. In practice, a combination of at least three independent sources is convincing: utility bill receipts, medical documents showing the same address, testimony from neighbors or staff of the homeowners' association (OSBB), correspondence, and service contracts at that address. The more independent confirmations there are, the less likely the other heirs will be able to cast doubt on the fact of cohabitation. Documents created while the deceased was still alive are especially valuable, since they do not depend on the will of either party to the dispute and are therefore seen by the court as the most reliable.

What is the difference between living with the deceased and living together as a family?

These are two different legal facts with different consequences. Permanent cohabitation with the deceased at the time the inheritance opened is needed to confirm acceptance of the inheritance without filing an application with a notary, and it concerns someone who is already a statutory or testamentary heir. Living together as a family for at least five years before the inheritance opened is a ground for belonging to the fourth priority group of statutory heirs — that is, for becoming an heir when there are no heirs in the first three priority groups. The second concept is most often needed by those who lived in what is sometimes called a civil (unregistered) marriage. Confusing these two facts leads to an incorrectly worded claim, and this is exactly why such applications get left without consideration. So before preparing documents, it is always worth deciding: are you confirming acceptance of an inheritance you already have a right to, or proving your right to be an heir at all. The answer determines both the applicable legal provision and the evidence you will need to gather.

Can the fact of living together as a family be established in special proceedings?

Not always. In case No. 686/19661/20, the Supreme Court held that establishing the fact of a man and a woman living together as a family without a registered marriage does not, on its own, create legal consequences for the applicant, and therefore that fact cannot be established in special proceedings. Special proceedings can establish a fact that directly affects the applicant's rights and is not connected with resolving an underlying dispute over a right. So if there is already a conflict between claimants to the inheritance, the court will leave the application without consideration and explain the right to file a lawsuit instead. The practical takeaway: before filing documents, honestly assess whether there is a dispute, and if there is, prepare a lawsuit from the outset. Otherwise you will spend several months on proceedings that end without a decision on the merits, while your deadlines and evidence only get worse in the meantime.

I was away from home for several months before my relative's death. Does that break the fact of cohabitation?

No, a temporary absence for a valid reason does not break the fact of permanent cohabitation. An heir is deemed to have permanently lived together with the deceased even where, for some period before the death, they were away — for example, on a long business trip, receiving medical treatment, or studying — and returned only after the deadline to accept the inheritance had already passed. What matters is not uninterrupted physical presence at the address, but an established way of life: where the person actually lives, where they keep their belongings, where they return to, and which address they pay utility bills for. That said, the absence will need to be explained and confirmed by documents — a business trip order, a medical discharge summary, or a certificate from the place of study. Without that, the other heirs will use the gap as an argument against you, claiming that you actually lived at a different address and that there was no cohabitation at the time the inheritance opened.

How much evidence does a court need to recognize the fact of cohabitation?

The law does not set an exact number: the court weighs the evidence according to its own inner conviction, checking each piece for relevance, admissibility, and reliability, as well as the sufficiency and interconnection of all the evidence together. Based on experience preparing documents for such cases, I can say this: one document is almost never enough, and two is often too few if the other side objects. It is best to have at least three independent sources of different types — an official document, payment records, and witness testimony. Evidence created while the deceased was still alive and independent of the applicant's own will is especially valuable: medical call-outs to the address, contracts with service providers, bank statements. That kind of evidence is the hardest for other heirs to rebut. If all you have is testimony from relatives who have an interest in the outcome of the case, the prospects are weak, and it is better to know that honestly in advance than to find out at the court hearing.
