Fiance and I own a home deeded as : JTWROS. He passed away in November. Lawyer is asking for mortgage info and to have house appraised. I thought this

This house will pass to you, but you may be liable for inheritance taxes for the portion of the house that you inherited from your fiance because as of the date of death you were not married, and there is an inheritance tax due if you are not related to the person that died.  The tax will be based on one half of the appraised value.
