A citizen of the United States had been residing in Mexico City. She had substantial properties in New York and in Mexico. In May 1965, she executed a will in New York disposing of all her properties wherever they may be found. She also provided that it is her intention that her will be probated in New York and that he estate by conducted under the jurisdiction of the State of New York. The residuary estate was bequeathed share and share alike to two friends in Brooklyn and in Texas. The will also stated that all taxes and penalties which the executor shall be required to pay should be paid out of her residuary estate without apportionment.
Eight months after the testator executed her New York will she executed a notarial will in Mexico in January 1966. And then in August 1966, she executed a second notarial will in Mexico.
The first will in Mexico provided for general legacies expressed in Mexican pesos and then she instituted as her sole heirs, three residents of Mexico City who all get one-third share in her estate after deducting the legacies. The second will in Mexico was a codicil. It revoked one general legacy. A New York Probate Lawyer said the naming of the three sole heirs was changed: only one was sole heir, the rest were heirs in equal parts. Both Mexican wills were silent about the New York properties and both were silent about the liability of the properties in Mexico to answer for estate taxes in the US.
