Заявитель переоформил водительское удостоверение.

Заявитель means applicant or person submitting an application/request.

It is related to заявление, which means application, statement, or formal request, but they are not the same word:

• заявление = the document/request
• заявитель = the person who submits it

The ending -тель often forms a noun meaning the person who does something. Compare:

• учить → учитель = teacher
• заявить → заявитель = applicant / declarant

In official or legal language, заявитель is very common.

Переоформил is the past tense, masculine, singular form of переоформить.

Russian past tense agrees with the subject in gender and number:

• он переоформил = he reissued/renewed it
• она переоформила = she reissued/renewed it
• они переоформили = they reissued/renewed it

Since заявитель is a grammatically masculine singular noun, the verb is переоформил.

Even if the real applicant were female, official language may still use a masculine noun like заявитель. In that case, learners should be aware that official Russian sometimes follows grammatical gender more than natural gender.

Переоформить means something like:

• to renew
• to reissue
• to re-register
• to redo the paperwork for

The exact English translation depends on context.

The verb is built from:

• оформить = to process formally, register, issue, put into official form
• prefix пере- = again / anew / re-

So переоформить literally suggests to formally process again.

With documents, licenses, permits, ownership papers, and similar things, it often means to renew or to have reissued.

Переоформил is perfective. It presents the action as completed.

So this sentence tells us that the applicant finished renewing/reissuing the driver’s license.

The imperfective partner is переоформлять. Compare:

• Заявитель переоформил водительское удостоверение.
  The applicant renewed/reissued the driver’s license.
  → completed result

• Заявитель переоформлял водительское удостоверение.
  The applicant was renewing/reissuing the driver’s license.
  → process, repeated action, or background

Russian uses aspect very heavily, so this is one of the most important things to notice in the sentence.

Because водительское удостоверение is the direct object of the verb, it is in the accusative case.

However, for inanimate neuter singular nouns, the accusative is usually the same as the nominative. That is why the form does not visibly change.

Here is the breakdown:

• удостоверение = ID / certificate / license document
• водительское удостоверение = driver’s license / driving license

This phrase is:

• neuter singular
• inanimate
• therefore nominative = accusative in form

So after the verb, you still see:

• водительское удостоверение

not because there is no accusative, but because the accusative looks the same here.

The adjective водительское must agree with удостоверение in:

• gender
• number
• case

Since удостоверение is:

• neuter
• singular
• accusative (same form here as nominative)

the adjective also takes the neuter singular ending:

• водительское

Compare:

• водительский документ = masculine
• водительская карта = feminine
• водительское удостоверение = neuter
• водительские документы = plural

So the ending -ое is simply agreement with the noun.

It is the formal, official term.

In everyday speech, Russians often say:

• права

For example:

• Я потерял права. = I lost my driver’s license.

But in official, legal, bureaucratic, or instructional language, you are very likely to see:

• водительское удостоверение

So the difference is roughly:

• водительское удостоверение = formal / official
• права = common everyday speech

Russian normally does not use лицензия for an ordinary personal driver’s license.

Instead, the standard term is:

• водительское удостоверение

The word лицензия is used for licenses in other senses, such as:

• business licenses
• software licenses
• professional licenses
• permits of certain kinds

So an English speaker should be careful not to overuse лицензия as a direct translation of license in every context.

Yes. Russian word order is more flexible than English because case endings carry much of the grammatical information.

The neutral order here is:

• Заявитель переоформил водительское удостоверение.

But other orders are possible, depending on emphasis:

• Водительское удостоверение заявитель переоформил.
  Emphasis on the driver’s license

• Переоформил заявитель водительское удостоверение.
  Less neutral; can sound stylistic or contrastive

Even though these are possible, the original sentence is the most straightforward and natural in neutral written style.

The stress is:

• заяви́тель
• переофо́рмил
• води́тельское
• удостовере́ние

Stress is important in Russian because it is not always predictable.

A learner may especially want to notice:

• заяви́тель — not on the first syllable
• переофо́рмил — stress stays on -фо́р-
• удостовере́ние — stress on -ре́-

Yes. Переоформил is broader than a single fixed English word.

Depending on context, it could mean:

• renewed the license
• had the license reissued
• updated it after a name change
• redid the official registration/details

So if you translate it into English, you choose the word that best fits the situation. Russian often leaves that slightly broader unless the context makes it precise.
