My Dad passed away and had a will but I was never contacted about the reading of his will

No.  Unless your father specifically required it, there is no "reading of the Will" in Texas.  Wills which have been submitted for probate are available at the probate court (or county court handling probate) for all to see, often on line.  Beneficiaries are required to be notified that they are beneficiaries after the will has been admitted to probate.
