Electricity dues are attached to the premises and not to the person. The old dues may be in the name of some other person but it is the responsibility of the existing owner or the user of the premise to keep the premise clear of any electricity dues to be eligible to get the electricity connection. The existing user or applicant of the connection may either make the payment themselves or ask the former owner to clear the dues. It is therefore always advisable to ensure before purchasing or occupying the property that it is clear from any electricity dues and/or have a specific clause for ownership of electricity dues in the relevant document for transfer of ownership of property.
