When the owner of a property dies, their property will need to be transferred to another person, usually a family member. This process can only begin once the High Court appoints an executor to deal with the administration of all assets of the deceased person, as well as all financial matters.
Until an executor is hired, no-one can act on behalf of the deceased estate. It also must be noted that all Powers of Attorney will also fall away. It is up to the executor to assign the house to an heir or 3rd party. Only at this stage can the transfer process of the property begin.
This transfer process can be quite detailed and often confusing. It is highly recommended that a reputable conveyancing attorney assists with this process.
