El titular està en contra de la comissió bancària.

Here el titular means the holder/owner, especially the person officially named on something like a bank account, card, contract, or policy.

In banking context, titular often means account holder.

Be careful: titular can mean different things in other contexts. For example, in journalism it can mean headline. So context matters.

Catalan often uses estar with expressions of attitude, position, or stance.

So:

• estar en contra de = to be against
• estar a favor de = to be in favor of

That is why the sentence uses està.

Using és here would sound wrong.

En contra de is a fixed expression meaning against.

So:

• estar en contra de alguna cosa = to be against something

Examples:

• Estic en contra de la proposta. = I’m against the proposal.
• Estan en contra del canvi. = They are against the change.

It works as a whole phrase, so it is best to learn it together.

Because en contra de is the full expression. The preposition de is required before the thing or person someone opposes.

So you say:

• en contra de la comissió
• en contra del projecte
• en contra dels canvis

Not just en contra la comissió.

Literally, comissió looks like commission, but in banking it often means a bank fee or charge.

So la comissió bancària is usually:

• the bank fee
• the banking charge
• sometimes the bank commission

A learner should know that the most natural English translation in many real situations is bank fee.

In Catalan, many descriptive adjectives normally come after the noun.

So:

• comissió bancària = banking/bank commission
• compte bancari = bank account
• targeta bancària = bank card

This is very common in Catalan and in other Romance languages too.

Catalan uses definite articles very often, sometimes more often than English.

So la comissió bancària is natural Catalan, even if English might sometimes say simply bank fees or a bank fee depending on context.

The article tells us we are talking about a specific fee or the fee as a known concept in the situation.

Catalan usually uses the definite article with singular countable nouns when talking about a specific person or thing.

So:

• El titular = the holder
• La comissió = the fee/commission

Leaving out the article would usually sound incomplete here.

The accent marks show which syllable is stressed.

• està → stress on the last syllable: es-TÀ
• comissió → co-mi-si-Ó
• bancària → ban-CÀ-ri-a

These accents are important in Catalan because they help with both pronunciation and sometimes distinguishing words.

Usually, for the meaning to be against, Catalan strongly prefers estar en contra de.

So this is the natural pattern:

• Està en contra de la comissió bancària.

Using just contra after estar would not be the normal choice here.

However, contra by itself does exist in Catalan in other structures, especially with meanings like against in a more direct or physical/oppositional sense.

The adjective must agree with the noun it describes.

Here:

• comissió is feminine
• so the adjective is also feminine: bancària

Compare:

• la comissió bancària
• el compte bancari

So:

• bancari = masculine singular
• bancària = feminine singular

This kind of agreement is very important in Catalan.

Both the article/noun and the verb would change if needed.

Examples:

• Els titulars estan en contra de la comissió bancària.
  = The account holders are against the bank fee.

Changes:

• El → Els
• titular → titulars
• està → estan

The phrase en contra de la comissió bancària stays the same unless that part also becomes plural.

It is neutral standard Catalan.

It sounds natural in:

• banking contexts
• customer service
• written notices
• news-style or formal explanation

It is not especially informal or slangy. It is the kind of sentence you could easily see in real-world Catalan.
