Just to clarify.
Were you deeded the property 10 months ago, and it was recorded then?
Or was there some sort of contingency on the Deed saying that it would only become active when she passes?
If the first, you become the owner of record then, 10 months ago, and the court may not have updated the records yet. Some counties only update their records yearly. Call your local courthouse to see how often they update their records, and if they have the deed on file.
If the second, you probably need to ask the probate attorney or the personal rep. if the deed has been filed yet.
If not, it may need to go through probate - but even so, it is probably able to be sold out of probate in order to liquidate the assets and then the amount it is sold for will be returned to the estate until the probate process is resolved. Only the executor of the estate will be able to do this. You should double check with your attorney about this since I am in no way an expert on this subject.
