The committee originally heard on 15 May that Heyes had been using the letters RIBA, when he was no longer entitled to, as he had not paid his membership fee.
Heyes was also found guilty of informing his client that he had secured planning permission for three properties when he had not, which cost his client money.
The hearing also ruled that Heyes had 'improperly withdrawn money' from the client account, although this was later repaid. The committee deemed that Heyes had failed to manage his personal and professional finances properly. He was ultimately declared bankrupt.
Having been declared bankrupt, the hearing also ruled that Heyes failed to notify the ARB of his bankruptcy, a condition which is set out in the Code of Conduct.
The architect was given six months to manage his finances and practice, and on 15 December Heyes was handed a reprimand as a penalty.
