Peace be upon you. The mere lack of communication from a father with his daughters does not mean that his guardianship over their marriage is nullified. Unless there is clear evidence indicating his unwillingness to intervene and relinquish his guardianship, granting them independence in marrying themselves, it is necessary to seek permission from their guardian, even in the scenario presented, regardless of whether the daughter is independent in her affairs or not. This is according to the views of Ayatollah Khamenei and Ayatollah Sistani, who both emphasize the importance of seeking permission from the guardian unless there are clear indications of abandonment of that role.
