Solicitamos la certificación igual que la apostilla.

Solicitamos is the first-person plural form of solicitar in the present indicative.

So it means we request, we ask for, or in administrative language we apply for.

In a sentence like this, it sounds quite formal and official.

Spanish often leaves out subject pronouns because the verb ending already shows who is doing the action.

Here, -amos in solicitamos already tells you it means we.

So:

• Solicitamos... = We request...
• Nosotros solicitamos... = also correct, but more emphatic

You would add nosotros only if you want contrast or emphasis.

Solicitar is more formal than pedir.

A native speaker would often use:

• pedir in everyday speech
• solicitar in official, legal, or bureaucratic contexts

Since certificación and apostilla are document-related terms, solicitar fits the formal tone very well.

Igual que usually means the same as or just like.

It introduces a comparison.

However, in this sentence it may sound a little unclear. A learner might wonder whether it means:

• the certification, just like the apostille
• or the certification as well as the apostille

Those are not exactly the same idea.

If the intended meaning is both documents are requested, Spanish would usually say something clearer, such as:

• Solicitamos la certificación y la apostilla.
• Solicitamos tanto la certificación como la apostilla.

So igual que is possible as a comparison, but it is not the clearest way to say and also.

It is grammatically possible, but it may sound ambiguous or a little odd without more context.

A native speaker may pause and ask: comparison in what sense?

If the idea is simply that both documents are being requested, more natural options would be:

• Solicitamos la certificación y la apostilla.
• Solicitamos tanto la certificación como la apostilla.

If the idea really is comparison, then igual que can work, but the sentence still may need more context.

Because both nouns are feminine singular:

• la certificación
• la apostilla

Spanish articles must agree with the noun in gender and number.

Also, after igual que, Spanish still uses the article because la apostilla is a complete noun phrase, not just a bare noun.

Not always.

• certificación often refers to certification, official attestation, or sometimes the formal certified text/document
• certificado more often refers to a certificate

In administrative Spanish, the exact meaning depends on context. A form or office may specifically ask for una certificación rather than un certificado, and that difference can matter.

So even though English may use certificate in both cases, Spanish may choose one word or the other more precisely.

Apostilla is a legal-administrative term. It usually refers to an apostille, especially the Hague Apostille, which authenticates a public document for use abroad.

In Spanish, people often simply say la apostilla when the context is clear.

So this is a normal standalone word in legal or document-related situations.

Usually not in this sentence.

Igual que is the more natural structure for comparisons like just like or the same as.

Igual a is more common in patterns such as:

• Es igual a... = It is equal/identical to...

So here, igual que is the better choice if you really want a comparison.

That is one reason the sentence feels unclear: it can be interpreted in more than one way.

A reader might understand it as modifying:

• the noun: the certification, like the apostille
• or the action: we request the certification, just as we request the apostille

Because that relationship is not very explicit, the sentence can sound vague.

If you want to remove the ambiguity, a clearer structure is better, for example:

• Solicitamos la certificación y la apostilla.
• Solicitamos la certificación, al igual que la apostilla.
  This is still comparative, but slightly more polished in formal writing.

Yes, a native speaker would understand the words, but they might still think the phrasing is a bit unusual depending on the intended meaning.

In Spain, for official paperwork, native speakers usually prefer very clear wording. So if the goal is simply to list required/requested documents, they would often choose:

• la certificación y la apostilla
• tanto la certificación como la apostilla

So the sentence is understandable, but not necessarily the most natural option for every context.
