Learn Italian: Nel caso in cui sorga una difficoltà, potrebbe avvisarmi? - In case a difficulty arises, could you notify me?

The phrase nel caso in cui (in case / in the event that) is a conditional conjunction that always requires the subjunctive mood because it introduces a hypothetical situation. Here, we use the present subjunctive sorga because the main clause refers to a potential present or future event.

What verb does sorga come from, and is it irregular?

It comes from sorgere (to arise, to rise). Like many verbs ending in -gere, the hard 'g' sound from its first-person present indicative (io sorgo) carries over into the present subjunctive, giving us sorga for the io, tu, and lui/lei forms.

Who is being addressed in this sentence?

The speaker is using formal speech, addressing someone as Lei (formal 'you'). We know this because potrebbe is the third-person singular conditional of potere. If it were an informal conversation, the speaker would use the second-person potresti.

Could I just say se sorge instead of nel caso in cui sorga?

Yes, you can. If you use se (if) to talk about a realistic future event, you generally use the indicative mood (se sorge una difficoltà). However, nel caso in cui emphasizes the hypothetical nature of the event ('just in the rare case that...') and elevates the formality of the sentence.
