Usiamo la visura catastale a condizione che sia valida.

In Italian, subject pronouns are often omitted because the verb ending already shows who is doing the action.

• usiamo = we use
• The ending -iamo tells you the subject is noi.

So Usiamo la visura catastale... naturally means We use the land registry report...

You could say Noi usiamo..., but that usually adds emphasis, contrast, or clarity:

• Noi usiamo la visura catastale, loro no. = We use the land registry report, they don’t.

Visura catastale is a set phrase in Italian. It refers to an official document from the land or property registry, showing cadastral information about a property.

Breakdown:

• visura = a report, record lookup, or official extract
• catastale = relating to the catasto, the land/property register

So la visura catastale is not just any report; it is a specific kind of property-record document.

Italian uses articles more often than English does.

• la visura catastale = the cadastral/land registry report

In many contexts, Italian prefers the definite article where English might sometimes omit it or use a more general wording.

Also, visura is a feminine singular noun, so the article is la.

In Italian, descriptive adjectives often come after the noun.

So:

• visura catastale = cadastral report / land registry report

This is very normal word order in Italian. Some adjectives can come before the noun, but technical or classifying adjectives like catastale usually come after it.

A condizione che means provided that, on condition that, or as long as.

It introduces a condition that must be satisfied.

So:

• Usiamo la visura catastale a condizione che sia valida.
• We use the land registry report provided that it is valid.

It is a common formal or neutral expression. A less formal alternative can sometimes be purché, depending on context.

Because a condizione che requires the subjunctive in Italian.

So after a condizione che, you do not use the normal indicative form è; you use the subjunctive form sia.

• è = indicative present of essere
• sia = subjunctive present of essere

This is one of the most important grammar points in the sentence:

• a condizione che + subjunctive

So:

• correct: a condizione che sia valida
• not correct here: a condizione che è valida

Sia is the third person singular present subjunctive of essere.

Here is the present subjunctive of essere:

• che io sia
• che tu sia
• che lui/lei sia
• che noi siamo
• che voi siate
• che loro siano

In this sentence, sia is used because it refers to la visura catastale, which is third person singular.

Because valida agrees with visura, which is a feminine singular noun.

• la visura = feminine singular
• therefore the adjective must also be feminine singular: valida

Compare:

• il documento è valido = masculine singular
• la visura è valida = feminine singular

So valida is matching the noun it describes.

Here valida means valid, acceptable, or still legally/officially usable, depending on the context.

For an official document, valida usually means that it is still considered acceptable for the intended purpose, for example:

• up to date
• officially recognized
• not expired or outdated for the procedure involved

So this is not just true or correct in a general sense; it is specifically about the document being valid for use.

Here che introduces the subordinate clause after a condizione.

You can think of:

• a condizione che = one complete expression meaning provided that

So in this sentence, it is best learned as a fixed structure rather than trying to translate che word by word.

Structure:

• main clause: Usiamo la visura catastale
• subordinate clause: a condizione che sia valida

The subject is understood to be la visura catastale.

So:

• Usiamo la visura catastale a condizione che sia valida means
• We use the land registry report provided that it is valid

Italian often avoids repeating the noun if it is already clear from the context.

If you wanted to make it fully explicit, you could say:

• Usiamo la visura catastale a condizione che la visura sia valida but that sounds unnecessarily repetitive in most cases.

Yes, that is close to the grammar, but it sounds rather formal or unnatural in everyday English.

A more natural English translation would usually be:

• We use the land registry report provided that it is valid
• We use the cadastral report as long as it is valid

So the Italian grammar includes a subjunctive, but English usually does not need to show that as clearly.

Yes, it sounds fairly neutral-to-formal, especially because of:

• visura catastale: technical/legal vocabulary
• a condizione che: a somewhat formal connector

This kind of sentence would fit well in:

• administrative language
• legal or property-related discussions
• professional communication

In more everyday conversation, speakers might choose simpler wording depending on context, but this sentence is perfectly natural in formal or technical Italian.
