1. If the will of grandfather is lost but is registered then a certified copy of it can be obtained from the office of registrar. You should hope that the will is probated as without probate it has only scrap value.

2. If the subsequent will made was got made from your grandmother under force it has to be challenged in the court which can set it aside as illegal. Unless the will by your grandmother in favour of her sons and daughters is set aside as illegal by the court it will hold its ground.

3. If the daughters are contemplating the sale of the house the first priority for your dad should be to stop the sale of the property as in the event it is sold and third party rights are created it will be difficult to impeach them in the court. To this end your dad can seek an urgent stay order from the court.

A title search in the office of the registrar would reveal the date of registration. You will require the assistance of a local lawyer in this regard.

If your grandfather's will was registered, you can get the copy of it from the registrar's office by tracing it from the approximate dates of registration. Once getting it, you can apply for grant of probate of the will based on which the further procedure namely partition between two brothers and registration plus possession of property can be taken.

In the absence of the said will, partition and separate possession of their individual share by all sharer through court of law will be the alternative solution to this problem.
