A friend, who mother has recently died, has been jointly left (with her brother) their mother's small apartment. There is a tenant in it who hasn't paid the rent for 3 months, he has a drug problem (she thinks he's using it as a drug den) and the letting agent , although initially managed to gain access once and said it was in a filthy disgusting state with lots of drug paraphernalia around, can no longer gain access to the flat nor communicate with the tenant (he is not responding). There would seem to be no landlords rights on this. The flat was beautifully decorated and newly carpeted when the tenant moved in. Has anybody had experience of this as a landlord or who know what my friends legal rights are. (The flat is in Wales which apparently has different laws with regard to letting property)
