If you  are not a Mexican citizen and own real property in a federal zone or within 100 kilometers of the ocean, you cannot hold title in your individual name. Title must be held through a Mexican trust which is called  Fideicomiso. The IRS several years ago finally issued a ruling stating that Fideicomisos actually were not foreign trusts, but a manner of holding title to property and therefore in most situations the beneficiaries of the Fideicomiso are not required to filed the IRS foreign trust reporting forms 3520 and 3520A.  We recommend you have a professional review your Fideicomiso document to make certain it qualifies for the exemption from having to file these forms. Failure to file these forms can result in substantial penalties.
