If I am currently living at my parents house, and my husband divorces me 1 time, then does my iddat have to be spent at my husbands house or at my parents house?

According to our fiqh there is not any concept of one, two or three talaq
If it has been recited and witnessed by two Aadil people then it is valid and in order otherwise it is not consider as Talaq.
During the iddat expenses should be paid by husband.
