Praise be to Allaah.
There is no
guarantee for the rights of your father’s wife if you register his property
in the name of one of your brothers; in fact there is no guarantee for the
rights of the other siblings if the property is registered in the name of
only one, as you want to do in this case. It is possible that this brother
may take over the entire estate on the basis of this registration that you
are asking for. In fact there have been many cases like this. Two wrongs do
not make a right.
Just as you have
rights with regard to your father’s property that you fear for, the wife
also has rights with regard to her husband’s property that she fears for.
Just as you fear that she may take over your father’s property, she fears
the same thing from you.
The reality is
that this solution offers no guarantees to anyone and it cannot be allowed.
But if you really
fear the possibility of undue influence for your father and his condition
does not let him distinguish between what is right and what is wrong, then
the Islamically prescribed way of dealing with that is to get a court
injunction that will prevent the carrying out of any of his instructions
given during the period when he was incapacitated and there was the
possibility of tampering or undue influence.
However we are
aware that there are far-reaching social difficulties that may stand in the
way of this solution, and there may also be legal difficulties in your
country, so you can convince your father to divide his property now among
all his heirs who are still alive and transfer ownership to them at the time
when it is divided.
In this manner
each party will be protected against tampering from the others.
And Allah knows best.
