Hypothetical example: The structure of the programme means the hardest evidence is gathered after the exciting part is over. During the conditional period the capital must remain invested, the enterprise must operate, and the jobs must be created, and each of those has to be provable later from records kept at the time. A household that treats approval as the finish line often finds the removal filing difficult, not because anything went wrong but because nobody was keeping the file.
The practical response is to decide at the outset who holds the records, what will be retained, and how often the position will be reviewed. A Cavan Monaghan family should diarise the conditional admission date, the second anniversary and the opening of the ninety-day window at the same moment they receive the good news.
