Estate Law Questions? Ask an Estate Lawyer.
This is an unfortunate situation, however he has many options, he needs to hire an Estate Attorney as soon as possible, if the Will was probated the Executor has to follow out the wishes of the deceased, he can force the Judge to make her sign over the property to your father, he can also file a motion in the court to have her removed as Executor, for failing to abide by the Will.
He can also file a lien on the property now, either a lis pendens and bring a suit against the Estate for ownership of the property, this should be done in the Probate court, with the help of an Estate Atty.
