Trust & estate lawyers who dabble infrequently in cross border matters, take notice! It is relatively easy to lose your way when advising a non-U.S. person with assets in the U.S. Shortcuts that work when clients and properties are located in the same jurisdiction may lead to horrific problems when clients are domiciled in one jurisdiction and property is located in another. Examples are (A) drafting two wills where each revokes the other, (B) allowing an individual having a foreign domicile to directly own financial assets in the U.S., such as shares of publicly traded stock or mutual funds, can result in unanticipated estate tax and long delays before heirs have access to the assets, (C) not knowing which I.R.S. information reporting forms must be filed when a new client is a recent arrival from abroad can yield significant penalties for the client, (D) allowing a resident, non-citizen individual to return to the home country is an invitation to unnecessary U.S. estate tax if the client retains investment assets and real property in the U.S., and (E) not noticing inconsistencies in residuary clauses in a principal will drafted in the home country and a U.S. property only will drafted in the U.S. begs for a will fight. Diane K. Roskies, a principal in the New York office of the Offit Kurman law firm, and Zachary Weitz, an attorney in the Los Angeles office of the same firm, explain the severe problems that may be encountered, but do so in a light hearted manner.
