に先立って means before, prior to, or in advance of.

So:

• 住民票の交付に先立って = before issuing the resident record / prior to the issuance of the resident record

This expression is more formal than 前に. It often appears in official, written, or procedural language.

Compare:

• 住民票の交付に先立って、市役所が申請書を確認する。
  = Before issuing the resident record, city hall checks the application form.
• 住民票を交付する前に、市役所が申請書を確認する。
  = A less formal way to say almost the same thing.

Here, の connects two nouns:

• 住民票 = resident record / certificate of residence
• 交付 = issuance / handing over officially

So 住民票の交付 means the issuance of the resident record.

This is a very common noun-linking pattern in Japanese:

• 書類の確認 = confirmation/checking of documents
• 申請書の提出 = submission of an application form
• 住民票の交付 = issuance of a resident record

In English, this often corresponds to of.

交付 is a noun meaning issuance, but it can also be used with する as a verbal noun:

• 交付 = issuance
• 交付する = to issue

In this sentence, the writer uses the noun form because it fits the pattern N に先立って:

• 交付に先立って = prior to the issuance
• not 交付するに先立って in this sentence

This kind of noun-heavy style is very common in formal or bureaucratic Japanese.

In the pattern N に先立って, the particle に marks the event that something happens before.

So the structure is:

• X に先立って、Y
  = Before X, Y happens = Prior to X, Y happens

Here:

• 住民票の交付 = the issuance of the resident record
• 住民票の交付に先立って = prior to the issuance of the resident record

This に is part of the fixed expression に先立って.

が marks the grammatical subject of 確認する.

So in this sentence:

• 市役所が = city hall is the one doing the checking
• 申請書を確認する = checks the application form

Together:

• 市役所が申請書を確認する = city hall checks the application form

The sentence is focusing on who performs the action.

を marks the direct object, meaning the thing directly affected by the verb.

Here:

• 確認する = to check / confirm
• 申請書を確認する = to check the application form

So:

• 市役所が = the subject, the doer
• 申請書を = the object, the thing being checked

This is the standard subject が + object を + verb pattern.

They are very close in meaning, but not identical in tone.

• 住民票の交付に先立って = formal, official, written, procedural
• 住民票を交付する前に = more neutral and conversational

Both mean before issuing the resident record, but に先立って sounds more administrative and polished.

This sentence uses language that sounds like something from an official notice, government explanation, or procedure manual.

They are similar, but the nuance is slightly different.

• 交付 often means officially handing over or issuing a document to a person
• 発行 often means issuing/publishing something, with emphasis on creating or officially putting it out

For government documents, 交付 is very common because it focuses on the document being officially given to the applicant.

So for something like a certificate, 交付 is a natural choice.

The plain dictionary form 確認する is often used in:

• written explanations
• official descriptions
• procedural statements
• textbook example sentences

It gives a neutral, factual tone.

Compare:

• 確認する = plain form, neutral written statement
• 確認します = polite form
• 確認した = past tense, checked

In this sentence, the writer is describing a general procedure, so 確認する fits well.

Yes. The sentence sounds quite formal and administrative.

Reasons:

• 交付 instead of a simpler verb phrase
• に先立って instead of 前に
• overall noun-heavy structure

This style is common in government, legal, and institutional contexts.

A more everyday version might be:

• 住民票を交付する前に、市役所が申請書を確認する。

That is easier for learners to process, but the original sounds more like actual official Japanese.

Here are the main readings:

• 住民票 → じゅうみんひょう
• 交付 → こうふ
• 先立って → さきだって
• 市役所 → しやくしょ
• 申請書 → しんせいしょ
• 確認する → かくにんする

So the full sentence is read:

じゅうみんひょう の こうふ に さきだって、しやくしょ が しんせいしょ を かくにんする。

No, standard Japanese normally does not use spaces between words like this.

The normal writing would be:

住民票の交付に先立って、市役所が申請書を確認する。

Spaces are often added in learning materials to make word boundaries clearer for beginners. They are a teaching aid, not standard spelling.
