Revisamos la notificación de la multa.

Revisamos comes from revisar, which often means to review, to check, or to look over.

In this sentence, it means something like:

• we review
• we check
• we go over

The most natural English choice depends on context.

Revisamos can be two different tenses:

• present indicative: we review / we check
• preterite: we reviewed / we checked

These two forms are spelled the same for nosotros verbs ending in -ar.

So by itself, Revisamos la notificación de la multa could mean either:

• We review the fine notice, or
• We reviewed the fine notice

Only context tells you which one is meant.

Because both nouns are feminine singular:

• la notificación
• la multa

Spanish uses articles very often, sometimes more often than English does. Here, both nouns are being treated as specific:

• the notification
• the fine

Also, notificación is feminine because nouns ending in -ción are usually feminine.

Here, de links the two nouns together.

la notificación de la multa means:

• the notification of the fine
• the fine notification
• the notice about the fine

So de is not really being translated word-for-word as only of. It is showing the relationship between:

• the notification
• and the fine

It tells us what the notification is about.

Not in this sentence.

Although de can sometimes mean from, here it connects two nouns, so it means something more like:

• of
• about
• related to

So la notificación de la multa is the notification about the fine, not something coming from the fine.

Multa means fine as in a money penalty, especially an official one.

Common examples:

• a parking fine
• a speeding fine
• an administrative fine

In Spain, multa is a very normal everyday word for this idea.

Not usually.

This is a common false friend.

In Spanish, revisar usually means:

• to check
• to inspect
• to review
• to look over

English revise often means to edit or to study again, but Spanish revisar does not always mean that.

So in this sentence, revisamos is more like we checked/reviewed, not necessarily we revised.

Because the direct object is a thing, not a person.

The direct object here is:

• la notificación

Spanish normally uses the personal a before specific people (and sometimes pets or personified beings), not before ordinary things.

So:

• Revisamos la notificación = correct
• Revisamos a la notificación = incorrect

Spanish commonly uses this structure:

noun + de + noun

So instead of putting one noun directly before another the way English often does, Spanish often links them with de.

Compare:

• the fine notification → la notificación de la multa
• the door of the house → la puerta de la casa

This is a very common Spanish pattern.

In normal everyday Spanish, that would sound unnatural.

The natural full sentence is:

• Revisamos la notificación de la multa

You might see reduced article use in:

• headlines
• notes
• administrative labels

But in a standard sentence, Spanish usually wants the articles here.

Not exactly.

La multa is the fine itself.

La notificación de la multa is the notification/notice of the fine — the official document or message informing you about it.

So it is closer to:

• the fine notice
• the notification of the fine

rather than simply the ticket, depending on context.

Because the stress falls on the last syllable: ción.

Without the accent, Spanish stress rules would make you expect the stress somewhere else, since words ending in n, s, or a vowel are normally stressed on the second-to-last syllable.

So the accent mark shows the correct pronunciation:

• no-ti-fi-ca-CIÓN

This is very common with nouns ending in -ción:

• información
• situación
• notificación

Yes, it sounds natural.

In Spain, this could easily be used in an administrative, legal, or everyday context if people are talking about checking a notice related to a fine.

Depending on the situation, native speakers might also say:

• Revisamos el aviso de la multa
• Revisamos la carta de la multa
• Revisamos la notificación de sanción (more formal)

But your original sentence is perfectly normal.
