I am so sorry for your loss.  The taxes need to be paid asap.  They are technically the responsibility of the estate but if you have been left the house or are the only heir then it will in reality be the same pocket.  In brief, the Will needs to be presented for probate in the probate court in the county in which your Father resided at the time of his death.  The proposed executor will give notice to all the potential heirs and then marshal the assets and deal with the debt.  The property is transferred via an executor's deed.  Good luck.
