What is the ruling on the paternal uncle remaining in his deceased grandmother's apartment with the consent of some heirs and the objection of others? Is he obligated to pay rent for the share of those who object? And what is the ruling on maintaining kinship ties with someone who demands their rights or has been wronged in other matters?

The deceased's estate is the right of all his heirs, and it is not permissible for any of them to exclusively reside in an inherited property without the permission of the others. If a dispute arises over the division of the estate, it is to be resolved through the Sharia judiciary.

Dealing with an oppressor involves forbidding him from his injustice, but his oppression does not prevent him from being given his right, such as maintaining kinship ties, for it is obligatory and cutting off kinship ties is not permissible, even if the relative is an oppressor. Some jurists have permitted shunning an oppressive relative if that would deter him from his injustice.

The questioner is advised to be keen on maintaining kinship ties and not cutting them off, and to beware of obsessive thoughts and to turn away from them.
