Tauranga Law's principal Kevin Olivier then sent Appleton a letter which, among other things, detailed some risks involved in the transaction.
Appleton's trust raised a loan to fund a deposit of $90,000 for the apartment, which was paid into a Blue Chip bank account.
Several years went by and the apartment was never built and Appleton contacted Blue Chip to get his refund back. This never happened, Blue Chip collapsed, Rockfort was liquidated and Appleton lost his deposit.
Appleton and his trust then took Tauranga Law to the High Court in 2011 alleging the legal advice he received was inadequate. Appleton claimed $112,000 from Olivier, together with interest and damages.
The High Court's Justice Christopher Allan found Olivier had been negligent, failed to provide proper advice and had therefore breached his duty of care. But the judge said Olivier's negligence had not caused Appleton's loss and so the claim failed.
Appleton and the family trust took the case to the Court Appeal and in September Justices Mark O'Regan, Christine French and Helen Winkelmann found in their favour.
The three judges said they saw Olivier's "failings as much more significant" than Justice Allan did.
"We must of necessity reassess the causation issue in light of our different conclusion on the nature of the breach of the duty," their decision said.
The judges awarded funds to Appleton and the trust but did not specify the exact amount in their decision.
However, Tauranga Law applied to take the case to the Supreme Court and leave for this appeal was granted this week.
No date has yet been set for this hearing.
