en caso de que + Subjunctive
In Case
'En caso de que' means 'in case' and is followed by the subjunctive to talk about a possible future event.
How It Works
The conjunction en caso de que translates to 'in case' or 'in the event that'. It's used to introduce a hypothetical situation or a provision for a possible future event.
A key rule to remember is that en caso de que is always followed by a verb in the subjunctive mood. This is because the clause describes a situation that is potential or uncertain, not a factual event.
Structure:
Main Clause + en caso de que + Subjunctive Clause
Example: Lleva un abrigo (main clause) en caso de que haga frío (subjunctive clause).
Important Distinction: 'en caso de' + Infinitive
When the subject of the main verb and the conditional verb is the same, you can often use the more concise structure en caso de followed by an infinitive verb.
- Different Subjects: Dejamos una llave (nosotros) en caso de que tú vengas (tú) más tarde.
- Same Subject: En caso de llegar tarde, avisaré. (This is a more concise way of saying: En caso de que yo llegue tarde, yo avisaré.)
This structure is similar to other conjunctions like para que and antes de que, which also require the subjunctive to express purpose or anticipation.

- En caso de que llueva, cogeré el paraguas.

Word by Word: In case that it rains, I will take the umbrella.
- Avísame en caso de que cambies de opinión.

Word by Word: Notify me in case that you change of opinion.
- Preparamos comida extra en caso de que vinieran más invitados.
We prepared extra food in case more guests came.
Word by Word: We prepared food extra in case that came more guests.
Here, 'vinieran' is in the imperfect subjunctive because the main verb 'preparamos' is in the past (preterite). The tense of the subjunctive must align with the tense of the main clause.
- Tengo un plan B en caso de que el plan A no funcione.
I have a plan B in case plan A doesn't work.
Word by Word: I have a plan B in case that the plan A not work.

Common Mistakes
Using the indicative mood instead of the subjunctive.
Te doy mi número en caso de que lo necesitas.Te doy mi número en caso de que lo necesites.The phrase 'en caso de que' expresses a possibility, not a certainty. Therefore, it must always be followed by a verb in the subjunctive mood ('necesites'), not the indicative ('necesitas').
Confusing 'en caso de que' with 'en caso de'.
En caso de que necesitar ayuda, llámame.En caso de necesitar ayuda, llámame.When the subject does not change, use 'en caso de' followed by an infinitive. Use 'en caso de que' + subjunctive when the subject of the second clause is different, or when you want to be explicit even with the same subject.
How It Connects
Learn This First
To use 'en caso de que' correctly, you must first be comfortable with the present subjunctive mood, as this conjunction always triggers it to express a hypothetical condition or contingency. Additionally, familiarity with basic prepositions helps in recognizing the structure of the phrase.

Related Patterns
- si + Present + Future/PresentReal Si Clauses (Present)
Both create conditional sentences, but 'si' clauses can describe real, likely, or hypothetical situations and use the indicative for real possibilities. 'En caso de que' specifically introduces a contingency or provision and always requires the subjunctive.
Level 3 - a menos que/sin que/con tal de que + SubjunctiveSubjunctive Conjunctions
These are other adverbial conjunctions that, like 'en caso de que', introduce a condition or stipulation that is not a fact, and therefore they also require the subjunctive mood.
Level 3 - antes de que + SubjunctiveBefore (Subjunctive)
'Antes de que' (before) introduces an action that has not yet occurred, making it hypothetical. This is similar to 'en caso de que', which introduces an action that may or may not occur. Both require the subjunctive.
Level 3 - por si (acaso) + Indicative/SubjunctiveJust in Case
A very close synonym meaning 'just in case'. 'Por si' is often used for simple precautions and can sometimes be followed by the indicative, whereas 'en caso de que' is a bit more formal and strictly requires the subjunctive.
