HANSON v. DENCKLA Case Reminder Citation Hanson v. Denckla. 357 U.S. 235 (1958) Statement of the case This is a civil action taking place in Federal Court. Plaintiffs brought an action against a Delaware trust company to have the trust executed in Florida. Motions Procedure US Supreme Court Statement of fact Dora Donner who opened a Trust first lived in Pennsylvania and created it with a company located in Delaware. The Dora Donner later moved to Florida and conducted a little bit of business with the trust which sent Dora some money to Florida. Dora later died and her relatives wanted the Trust settled in Florida. The record shows that the administrator of the trust did not perform any acts in Florida, it just sent Dora some one the money from the trust. Issue Whether or not Florida has in personam jurisdiction over a Delaware company that did no business in Florida but sent some remittances of trust money to the trustor. Decision No Florida does not have in personam jurisdiction over a Delaware company that did not do business at all in Florida Rule Where a company strictly has unilateral activity with a client that activity is not sufficient enough to establish in personam jurisdiction. Reasoning Florida could not have in personam jurisdiction over a Delaware trust company because the trust company did not have any contacts in Florida and the communication with their client was unilateral. The application of that rule will vary with the qualitt and nature of the defendants activity but it is essential in each case that there be some act by which the defendant purposefully avails itself of the privilege of conducting activities within the forum state, thus invoking the benefits and protections of its laws.
