Disinheriting wife

In New York, you can't disinherit your spouse.  Under New York Estates, Powers and Trusts Law (EPTL), a surviving spouse has the option of taking the the greater of $50,000 or 1/3 of the net estate.  The net estate excludes some property, namely property that passes to the spouse automatically, anyway.  The long and short of it is, under the NY EPTL, a spouse can still inherit despite the Will. Additionally, you may have a claim to take ownership of the house, if any, outright.

Note:  The paperwork necessary for the elective share must be filed prior to when the 6 month statute of limitations runs.
