İtiraz dilekçesindeki tebliğ tarihi doğru.

A natural breakdown is:

• itiraz = objection, appeal, challenge
• dilekçe = petition, written application
• dilekçesindeki = in/on the petition
• tebliğ = notification, official service of a document
• tarihi = its date / the date of
• doğru = correct

So the structure is basically:

• İtiraz dilekçesindeki = the one in the objection petition
• tebliğ tarihi = notification date / date of service
• doğru = is correct

In smoother English, this means something like The notification date in the objection petition is correct.

Turkish often builds meaning by adding suffixes to a base word.

Here is the structure:

• dilekçe = petition
• dilekçesi = his/her/its petition or, in this kind of noun phrase, the petition
• dilekçesinde = in/on the petition
• dilekçesindeki = the one that is in/on the petition / the ... in the petition

So -deki / -daki turns a location phrase into something adjectival.

You can think of it like this:

• masada = on the table
• masadaki kitap = the book on the table

Likewise:

• dilekçesinde = in the petition
• dilekçesindeki tebliğ tarihi = the notification date in the petition

In this sentence, -ki is attached after a location ending and makes the phrase describe a noun.

Pattern:

• evde = at home
• evdeki çocuk = the child at home

Here:

• dilekçesinde = in the petition
• dilekçesindeki tebliğ tarihi = the notification date that is in the petition

So -ki is doing something like that is in/on/at... or simply the ... in/on/at... in English.

It is very common in Turkish for making relative-style descriptions without needing a separate word like that.

Because this is a Turkish noun compound.

In Turkish, when one noun modifies another noun, the second noun usually takes a possessive-style ending. So:

• itiraz = objection
• dilekçe = petition
• itiraz dilekçesi = objection petition / petition of objection

This is a standard construction. Some similar examples:

• öğrenci kimliği = student ID
• otobüs durağı = bus stop
• mahkeme kararı = court decision

So itiraz dilekçesi is the normal Turkish way to say objection petition.

In Turkish, the verb to be is often omitted in present-tense statements, especially in simple equational sentences.

So:

• Hava güzel. = The weather is nice.
• Bu doğru. = This is correct.
• Tebliğ tarihi doğru. = The notification date is correct.

Turkish does not need a separate present-tense word like is in these cases.

If you wanted to make it past or future, then Turkish would show that more explicitly:

• Tebliğ tarihi doğruydu. = The notification date was correct.
• Tebliğ tarihi doğru olacak. = The notification date will be correct.

Here, doğru is an adjective meaning correct.

It describes tebliğ tarihi:

• tebliğ tarihi doğru = the notification date is correct

But doğru can also appear in other roles in Turkish. For example:

• as an adjective: doğru cevap = correct answer
• as an adverb in some contexts: doğru konuşmak can mean to speak truthfully/correctly depending on context
• as a postposition in another structure: eve doğru = toward home

So in this sentence, it is definitely the adjective correct.

It is another noun compound:

• tebliğ = notification / official service
• tarih = date
• tarihi = date of ...

So:

• tebliğ tarihi = notification date / date of service

This is the same compound pattern as:

• doğum tarihi = date of birth
• başvuru tarihi = application date
• mahkeme tarihi = court date

In English, we often use of or just stack nouns. Turkish usually uses this compound structure instead.

Turkish usually puts modifiers before the thing they describe.

So the whole noun phrase comes first:

• İtiraz dilekçesindeki = in the objection petition
• tebliğ tarihi = notification date

Together:

• İtiraz dilekçesindeki tebliğ tarihi = the notification date in the objection petition

Then the predicate comes at the end:

• doğru = correct

So the sentence order is:

• [described noun phrase] + [predicate]

This is very normal in Turkish.

English often says:

• The notification date in the objection petition is correct.

Turkish builds that as:

• In-the-objection-petition notification-date correct.

Yes. A few possible alternatives are:

• İtiraz dilekçesindeki tebliğ tarihi doğrudur.
• İtiraz dilekçesinde yer alan tebliğ tarihi doğru.
• İtiraz dilekçesindeki tebliğ tarihi yanlış değil.

The first one, doğrudur, is a bit more formal or assertive than plain doğru. In legal or official Turkish, -dır/-dir/-dur/-dür is common.

So:

• doğru = correct
• doğrudur = is correct / is indeed correct

Both are grammatical.

Because the phrase behind it is not just dilekçe but itiraz dilekçesi.

That compound is:

• itiraz dilekçesi = objection petition

When you then say in the objection petition, Turkish uses the full compound form:

• itiraz dilekçesinde = in the objection petition

Then adding -ki gives:

• itiraz dilekçesindeki = the one in the objection petition

If you said dilekçedeki, that would mean in the petition, but it would not include the full compound objection petition.

So dilekçesindeki preserves the noun-compound structure.

The location part is the locative case:

• -de / -da / -te / -ta = in, on, at

Inside dilekçesindeki, the locative is:

• dilekçesinde = in/on the petition

Then -ki is added:

• dilekçesinde + ki = dilekçesindeki

So the locative is still there, but the full form now works like an adjective modifying tebliğ tarihi.

Yes, or at least strongly associated with formal and legal/administrative language.

Words like:

• itiraz
• dilekçe
• tebliğ

are common in legal, bureaucratic, and official contexts.

Especially tebliğ has a more formal/legal feel than a general everyday word for informing someone. In law, it often refers to official notification or service of documents.

So while the grammar is ordinary Turkish, the vocabulary is definitely formal and administrative.
