Oprávněná osoba má doklad o vlastnictví z katastru nemovitostí.

Because osoba is a feminine noun in Czech, so the adjective has to agree with it:

• oprávněná osoba = an authorized / entitled person

This agreement happens even if the actual person is male. In Czech, grammatical gender and real-life gender are not always the same thing.

So:

• oprávněná = feminine singular
• osoba = feminine singular noun

No. Osoba means person, and it can refer to any person, male or female.

The noun is grammatically feminine, so words around it are feminine too:

• oprávněná osoba

But the real person could still be a man.

This is similar to how some languages assign grammatical gender to nouns without that always matching biological sex.

Here oprávněná means something like:

• authorized
• entitled
• eligible
• having the legal right

So oprávněná osoba is not just any person, but a person who is legally allowed or entitled to do something.

The adjective comes from the verb oprávnit = to authorize / entitle.

Osoba is in the nominative singular, because it is the subject of the sentence.

The basic structure is:

• Oprávněná osoba = subject
• má = verb
• doklad... = object

So the sentence literally works like:

• The authorized person has...

Má is the 3rd person singular form of mít = to have.

So:

• já mám = I have
• ty máš = you have
• on / ona / ono má = he / she / it has

In this sentence:

• Oprávněná osoba má... = The authorized person has...

Doklad here means document, proof, or certificate.

Depending on context, doklad can mean different kinds of official documents, for example:

• osobní doklad = ID document
• daňový doklad = tax document
• doklad o zaplacení = proof of payment

In this sentence, doklad o vlastnictví means a document proving ownership.

In Czech, some nouns and expressions regularly use o + locative.

Here:

• doklad o něčem = a document/proof about something, or proving something

So:

• doklad o vlastnictví = proof/document of ownership

This is just the normal Czech pattern for this phrase.

Other examples:

• informace o firmě = information about the company
• zpráva o nehodě = report about the accident

After o in this meaning, Czech normally uses the locative case.

So in:

• o vlastnictví

the noun vlastnictví is in the locative singular.

A useful detail: for many neuter nouns ending in -í, the nominative and locative forms look the same.

So:

• nominative: vlastnictví
• locative: o vlastnictví

Same form, different grammatical function.

Vlastnictví means ownership.

It is a neuter noun:

• to vlastnictví

Related words:

• vlastník = owner
• vlastnit = to own
• vlastnický = ownership-related / proprietary

So:

• doklad o vlastnictví = proof of ownership

It means from the real estate cadastre / land registry.

More literally:

• z = from
• katastru = cadastral register / cadastre
• nemovitostí = of real estate / immovable properties

So the whole phrase means that the document comes from the official property register.

Because the preposition z requires the genitive case.

The dictionary form is:

• katastr

But after z:

• z katastru = from the cadastre

This is a common pattern:

• z domu = from the house
• z úřadu = from the office
• z katastru = from the cadastre

Nemovitostí is the genitive plural of nemovitost = real estate / immovable property.

It is genitive plural because it depends on katastr in the phrase:

• katastr nemovitostí = cadastre/register of real estate

So:

• nemovitost = one property
• nemovitosti = properties / real estate
• nemovitostí = of properties / of real estate

This is a fixed official phrase in Czech:

• katastr nemovitostí

Because Czech structures the idea differently.

English often uses:

• real estate
• land registry

Czech uses:

• katastr nemovitostí literally cadastre of immovable properties

So Czech treats the idea as a plural set of properties. This is normal and idiomatic.

Yes, Czech word order is more flexible than English, because case endings show grammatical roles.

The neutral order here is:

• Oprávněná osoba má doklad o vlastnictví z katastru nemovitostí.

But other orders are possible for emphasis, for example:

• Doklad o vlastnictví z katastru nemovitostí má oprávněná osoba.

That version puts more focus on the document.

Still, the original sentence sounds natural and straightforward, especially in official or legal language.

It sounds official and somewhat legal/administrative.

Words like:

• oprávněná osoba
• doklad o vlastnictví
• katastr nemovitostí

are very common in forms, regulations, offices, and legal contexts.

In everyday speech, people might say something simpler depending on context, but this sentence is perfectly normal in official language.

Yes. It is one noun phrase centered on doklad.

Its structure is:

• doklad = the main noun
• o vlastnictví = specifies what kind of document
• z katastru nemovitostí = specifies where it is from

So the whole object is:

• doklad o vlastnictví z katastru nemovitostí

In English, that is something like:

• a proof of ownership from the land registry

In practice, it is understood as describing the document:

• a document of ownership from the land registry

Not:

• ownership from the land registry

So the natural reading is that the document comes from that official register.

Czech sometimes allows phrases to attach a bit more loosely than English, but here the intended meaning is clear from context.
