Arra hivatkozva, hogy van bizonyíték, benyújtjuk a kárbejelentést.

It is a formal Hungarian pattern meaning something like citing the fact that..., on the grounds that..., or by referring to the fact that...

It has three parts:

• arra = to that / on that
• hivatkozva = referring / citing
• hogy... = that...

So arra hivatkozva, hogy van bizonyíték literally feels like:

referring to that, that there is evidence

In natural English, that becomes:

• citing that there is evidence
• on the grounds that there is evidence
• claiming that there is evidence

It is a formal, bureaucratic-sounding expression.

Because the verb hivatkozik takes the suffix -ra/-re.

The basic pattern is:

• hivatkozik valamire = to refer to something
• hivatkozik arra, hogy... = to refer to the fact that...

So:

• arra is the az pronoun in the -ra form
• it matches the government of hivatkozik

This is not a direct object, so azt would not fit here.

Compare:

• hivatkozom erre = I refer to this
• hivatkozom arra, hogy igazam van = I refer to the fact that I am right

Hivatkozva is an adverbial participle.

It comes from the verb:

• hivatkozni = to refer to / to cite / to invoke

The ending -va/-ve often creates a form meaning something like:

• while doing
• having done
• by doing

So hivatkozva means roughly:

• referring
• by referring
• citing

In this sentence, arra hivatkozva works like a fixed formal phrase meaning:

• by citing that
• on the basis of that claim

Hogy introduces a clause, similar to English that.

The structure is:

• arra hivatkozva, hogy...
• literally: referring to that, that...

In Hungarian, this kind of correlative structure is very common:

• arra gondolok, hogy... = I am thinking that...
• attól félek, hogy... = I am afraid that...
• arra hivatkozik, hogy... = he/she refers to the fact that...

So arra points forward, and hogy introduces the actual content.

Because this is an existential use of van: it means there is evidence.

In Hungarian, when you are saying that something exists or is available, you often use a bare noun without the definite article:

• van pénz = there is money
• van idő = there is time
• van bizonyíték = there is evidence

If you said van a bizonyíték, that would usually sound odd in this context. The sentence is not talking about the specific evidence as a known item in focus; it is simply stating that evidence exists.

Benyújtjuk is:

• from benyújt = to submit / to file
• present tense
• we form
• definite conjugation

Hungarian uses definite conjugation when the verb has a definite direct object.

Here the object is:

• a kárbejelentést = the damage report / the claim report

Because the object is definite, the verb is definite too:

• benyújtjuk = we submit it / we file it

Compare:

• benyújtunk egy kérelmet = we submit an application
  indefinite object → benyújtunk
• benyújtjuk a kérelmet = we submit the application
  definite object → benyújtjuk

The prefix be- often gives the idea of in, into, or a completed directional action.

With nyújt:

• nyújt by itself can mean to extend, to offer, to provide
• benyújt means to submit, literally something like to hand in

So be- helps create the specific meaning file/submit officially.

This is very common in Hungarian verbs:

• ír = write

• beír = write in / enter

• ad = give
• bead = hand in / submit

The -t marks the accusative, which is the usual case for a direct object.

The base noun is:

• kárbejelentés = damage report, loss report, or in insurance context claim notification

As a direct object:

• kárbejelentést

With the article:

• a kárbejelentést = the damage report / the claim report

So the sentence is literally:

• we submit the claim report

Yes, it is a compound noun, which is very common in Hungarian.

It is built from:

• kár = damage, loss
• bejelentés = reporting, notification, declaration

Together:

• kárbejelentés = damage report, report of damage, insurance claim notification

Hungarian often packs ideas into one long compound where English might prefer two or three words.

Yes, Hungarian word order is flexible, but this order is natural and formal.

The sentence starts with:

• Arra hivatkozva, hogy van bizonyíték, ...

This sets up the reason/background first, and then gives the main action:

• ... benyújtjuk a kárbejelentést.

So the structure is:

1. reason or justification
2. main action

That is very normal, especially in formal writing.

You could rearrange parts in Hungarian, but this version sounds like official or administrative language.

Because Arra hivatkozva, hogy van bizonyíték is an introductory subordinate structure.

The commas show that this is a separate background clause before the main clause:

• Arra hivatkozva, hogy van bizonyíték, benyújtjuk a kárbejelentést.

Hungarian punctuation often uses commas before subordinate clauses introduced by hogy, and also after a longer introductory phrase before the main clause.

Yes. Hungarian often uses the present tense where English might use will or another future expression, especially when the action is planned, intended, or part of a formal statement.

So benyújtjuk can mean:

• we submit
• we are submitting
• we will submit

The exact time depends on context.

In a formal statement like this, it can easily mean something like:

• we are hereby submitting
• we will submit

Yes, it sounds formal and bureaucratic.

Expressions like arra hivatkozva and benyújtjuk a kárbejelentést belong more to legal, administrative, insurance, or official language than to casual conversation.

A more everyday Hungarian sentence might use a simpler structure, depending on the situation. But for official-style wording, this sentence is quite natural.

Yes. Bizonyíték is a general word meaning evidence or proof.

Depending on context, Hungarian might also use more specific nouns, such as:

• dokumentum = document
• tanúvallomás = witness statement
• felvétel = recording
• igazolás = certificate / confirmation
• bizonyítékok = pieces of evidence

But van bizonyíték is a very standard general phrase meaning there is evidence.

Yes.

• bizonyíték = evidence, proof as a thing
• bizonyítás = proving, demonstration, the act or process of proof

In this sentence, you need bizonyíték, because it means that some evidence exists.

So:

• van bizonyíték = there is evidence

But bizonyítás would refer more to the process of proving something, not the evidence item itself.
