I hope this answer helped you.
New York Law is if you die without a will
all your inheritance goes to next of kin.
Which is a spouse, a child or grandchild, sibling, then it
goes to nieces and nephews.
Your aunt's estate has to pay taxes, so you will
have to go to a CPA accountant . Also, if there is a great
amount of assets you should go to an attorney
this might involve probate court.
and, oh, yes, the property cannot be sold until you seek
a real estate attorney's services.
