Transferring Deed where owner is deceased

You would not need to probate your mom's estate as long as you have one of her death certificates.  The property automatically passed to your dad upon your mom's death.  You should transfer the property form your dad to yourself using your executor certificate.  You will sign the deed as the executor of your dad's estate.  On the affidavit of title that goes with the deed you will list your mom's name and date of death and include your mom's death certificate.
