How are heirs to a property identified?

Start with the owner and the particular right

First establish whose succession is being investigated and which property right is involved. The starting point may be a registered owner, acquisition deed or earlier court decision. Link the individual to the property and check whether later documents changed ownership or the size of the share.

A matching surname is insufficient. Record known names, birth names, dates and places of birth, marriage and death, spouses and children, and the source for each fact. Identify gaps explicitly instead of filling them with assumptions.

Family relationships are only part of the picture

A family tree describes relationships but does not itself establish inheritance rights. A will, dates of death, rejection of inheritance and other legal circumstances can affect who inherits. Rules applicable to the particular succession must be checked rather than applying today's law automatically to every historical death.

Successive deaths require a separate chain for each deceased person. Family accounts are research leads. Formal evidence of inheritance requires the relevant court or notarial documents. A genealogical report can support that process but does not replace those documents.

Where to look for evidence

Combine sources according to the question that needs answering:

• birth, marriage and death records for events and family relationships;
• court files and notarial documents for earlier decisions and transactions;
• land registers and acquisition deeds to connect people with property rights;
• archives, historical lists and local records for background and chronology;
• letters, death notices and family notes as leads requiring verification.

The Polish State Archives provide genealogy guidance. Szukaj w Archiwach provides collection descriptions and available scans. An absent online scan does not prove that a document does not exist. Identify the archive and reference, then check access arrangements. Historical place names, parishes, languages and border changes can be relevant.

Avoiding mistaken identity

Illustrative example: two men called Jan with the same surname lived in one town. One matches the approximate age but his marriage record names different parents. Do not add him to the tree based on the surname alone. Compare parents, spouse, dates, address and the sequence of events.

For each proposition, record what the document proves, what it leaves unresolved and how it connects to other records. Note archive references, record numbers and pages. Treat an online index or family tree as a pointer to the underlying record. Describe inconsistencies openly so that a later legal assessment can evaluate them.

Civil status records and living people

Access to civil status certificates is restricted by rules governing entitlement, family relationship or demonstrated legal interest. Gov.pl explains who can obtain a certificate and how. General curiosity about a family does not automatically entitle someone to any other person's records.

Research and contact with living relatives should use only information relevant to the case. There is no need to publish a complete tree containing living people's details. A first enquiry to HEREDITAS can describe the problem without identity numbers or complete case files.

Emigration and foreign documents

Emigration may lead to different surname spellings and records issued in another country or language. Preserve original spellings and explain the evidence connecting them with Polish records. Translation and document-form requirements depend on the intended procedure and country of origin.

Cross-border family research must be combined with analysis of applicable law and jurisdiction. EU succession rules and the European Certificate of Succession may be relevant, depending on the circumstances. A foreign document should not automatically be assumed sufficient for a Polish register entry.

What should the result contain?

A useful report lets someone else follow and verify the reasoning. It should include:

• identified people and relationships relevant to the succession;
• a chronology of deaths and successive inheritance links;
• a source list and documents supporting each link;
• clearly marked hypotheses, inconsistencies and missing evidence;
• remaining searches and issues requiring legal assessment.

Organised evidence helps decide whether the next step is another record, contact with a person, inheritance proceedings or a register update. HEREDITAS connects genealogical findings with property analysis and coordination. Acceptance and the scope of work depend on the initial assessment.
