Thanks for the is response. I am eager to know the followings;
1) As you said, he is liable to pay off this dues. Is there any act/regulation? Electricity department engineer is looking for this. If there is any web site we can refer to?
2) Is there any other methodology to get the electricity connection? The previous owner has moved from there residence to some south Indian state, which we are not aware of. I am afraid if a legal notice is sent to them, it would be returned back as they do not live there.
