My wife is a German she wants to draw up a will in the US. Will it be valid in Germany and Canada?
If done properly, Germany and Canada will recognize the Will executed in the United States.
There is a treaty that mandates that "international wills" be recognized if special procedures for their execution are followed.
In Colorado, where I practice, these procedures are set forth in the state's probate code, which is its local version of the Uniform International Wills Act which most states adopt in order to implement the treaty. It is set forth a Colorado Revised Statutes Sections 15-10-1101 to 15-10-1110.
