Revisamos la apostilla igual que la legalización.

Revisamos is the 1st person plural form of revisar, so it literally means we review / we check / we inspect.

In this sentence, it most naturally means:

• we review
• we check

A useful thing to know: revisamos can be either:

• present tense: we review / we check
• preterite (past): we reviewed / we checked

So by itself, revisamos is ambiguous. The surrounding context tells you which one it is. In a general statement like this, it is usually understood as the present.

Because both nouns are feminine singular:

• la apostilla
• la legalización

Spanish uses definite articles very often, sometimes more often than English does. So even if English might sometimes sound natural with less article use, Spanish often keeps it.

Here, la is simply the normal definite article meaning the.

They are feminine because they are feminine nouns in Spanish.

• apostilla ends in -a, which is very often feminine.
• legalización ends in -ción, and nouns ending in -ción are typically feminine.

So:

• la apostilla
• la legalización

And if you used adjectives with them, those adjectives would normally agree in the feminine too.

Igual que means the same as, just like, or in the same way as.

So the structure is:

• Revisamos la apostilla igual que la legalización.
• We review the apostille just like the legalization.

It introduces a comparison between the two things.

A simple way to think about it:

• X igual que Y = X like Y / X the same as Y

Sometimes yes, but they are not always exactly the same in tone.

• igual que = just like / the same as
• como = like / as

In many everyday comparisons, both can work, but igual que usually makes the idea of sameness more explicit.

So:

• Revisamos la apostilla igual que la legalización.
• Revisamos la apostilla como la legalización.

The first one sounds more clearly like we handle one the same way as the other.

For a learner, it is safest to understand igual que here as just like.

No. It does not mean they are the same thing.

It means they are being reviewed in the same way.

In other words, the sentence compares the treatment/process, not the identity of the two documents.

A fuller version in English would be something like:

• We review the apostille in the same way as the legalization.

So the meaning is about how something is reviewed.

Because Spanish often omits repeated words when the meaning is clear.

The full logical idea is:

• Revisamos la apostilla igual que revisamos la legalización.

But Spanish normally shortens that to:

• Revisamos la apostilla igual que la legalización.

This kind of omission is very common. English does it too:

• We review the apostille just like the legalization
  instead of
• We review the apostille just like we review the legalization

So the verb is understood in the second part.

Normally, no. Revisamos is not the usual way to say let’s review.

To suggest an action together, Spanish more commonly uses:

• revisemos = let’s review

So:

• Revisamos = we review / we reviewed
• Revisemos = let’s review

That is an important difference.

Here apostilla is a noun, and in this context it is a legal/official term.

Grammatically:

• singular
• feminine
• common noun

So in the sentence, it is the direct object of revisamos:

• Revisamos → what do we review?
• la apostilla

Yes, but the basic sentence is the most neutral order.

The original:

• Revisamos la apostilla igual que la legalización.

You could also say:

• Igual que la legalización, revisamos la apostilla.

That version puts more emphasis on the comparison.

But for a straightforward statement, the original word order is the most natural and standard.

A more explicit version would be:

• Revisamos la apostilla igual que revisamos la legalización.

This repeats the verb and makes the comparison completely clear.

Another natural option is:

• Revisamos la apostilla de la misma manera que la legalización.

That spells out the idea of in the same way even more clearly.

The original sentence is shorter and perfectly normal, but these expanded versions can help learners see the structure more easily.
