Contact a Wisconsin attorney who does estate AND special needs planning.  You may want to use the Find a Lawyer function of the National Academy of Elder Law Attorneys (www.naela.org)   You may want to name your daughter as the beneficiary and a special needs trust for your grandson as the contingent beneficiary on your annuities (assuming that they pay after your death). If you die and your daughter inherits while he is a minor (under 18), she might have too much income for him to continue receiving SSI.  Depending on the circumstances, you may want to name your daughter and a special needs trust for your grandson to each receive a certain percentage of the annuities (and anything else in your estate). Please note that you may want one Will specificially to govern your Stateside assets and another Will to govern your assets in the country in which you live.  Both Wills should state that they only govern the assets in a certain country. There is nothing wrong with using a Stateside "care of" address.  Many Americans resident abroad have US post office boxes specifically to receive their mail, including bank statements.  Many use a service to collect and forward that mail.
