Now at the death of her husband, can she come for iddah to her late husband’s house or not after not being in any kind of relationship or any kind of contact with the husband for 35 years?
بسم الله الرحمن الرحيم
In the question mentioned above, if the husband did not divorce his wife then the woman shall remain in his nikah as usual though they have not had any contact for a long time. If the husband died it is necessary for the woman to return to the house of the husband for the iddah.
Allah knows Best!
