My wife and I reside in nys in a condo. The title to this condo is in my name only. I do not have children and my will stipulates that upon my death my wife will be come a sole beneficiary. Given the above described circumstances ,does it make any difference,for the purpose of the NYS and federal estate tax,whether the title to the condo is in my name only or in both names.? If in fact it makes a difference ,does the completion of the waranty deed(husband to himself and wife) form and the warrany deed,tenants by the entirety,and not tenants in common or joint tenants form, signed by a notary public,is sufficient to consider my wife to be a coowner of the condo or some additional steps are required?
