Rent Smart Wales, the licensing and training regime which is now a year old, has taken an agent and a landlord to court for failure to abide by its requirements.
Yvette Phillips, trading as estate agent R Miles Scurlock of Milford Haven, Pembrokeshire, failed to submit a completed licence application or register her rental properties.
She was issued with a Fixed Penalty Notice in June this year but she failed to pay, submit a licence application or register the properties despite further reminders.
Cardiff Magistrates fined Phillips £4,600 for three offences under the Housing (Wales) Act 2014, ordered her to pay court costs of £671 and a £170 victim surcharge.
Self-managing landlord Damian Cross of Rhodfa'r Gwagenni, Barry was also found guilty of failing to become licensed for letting and management activities for a property at Barry.
Cross had registered the property but not applied for a licence. He failed to pay a Fixed Penalty Notice for his non-compliance, or submit a licence application or appoint an agent.
He was fined £660 for two offences under the Housing (Wales) Act 2014, and ordered to pay court costs of £543 and a £33 victim surcharge.
