The linked piece appears to be a perfectly accurate account of the way the court system works in the UK, and therefore presumably in Alderney. There is, however, one critical flaw in this plan. As the piece rightly says:
"If Filco do not turn up and defend your claim, the court will grant judgment in default and order Filco to pay you your money back."
However, if they turn up to offer a defence and you are not present to state your arguments the reverse is likely to happen, and the court will rule against you. Therefore, you should budget for flights to Alderney, hotels etc, which rather alters the financial attractiveness of this course of action.
You could possibly brief an Alderney lawyer to represent you at court rather than appearing personally, but that would also eat away any money you might win.
There is a further problem also. Even if you do win, it does not mean that you will receive immediate payment. The losing party can plead that his financial circumstances make it difficult for him to pay at once and he can offer a "Proposal for Payment". This would usually consist of a promise to pay by a specified future date, or a plan to pay by small instalments over an extended period. It is normal for the court to approve such proposals unless they are seen to be an obvious attempt to unreasonably delay payment. Therefore, you may win and finish up only with a promise of payment within the next (say) two years, which is not very different from the position you are in currently.
