Elder law attorneys, guardians, conservators, and judges are frequently faced with sorting out complex jurisdictional issues caused by our society’s increasing mobility. For example, a person with declining capacity may need the assistance of a guardian, but if she has spent time in more than one jurisdiction, or needs to be moved to another area to receive care, where should the guardianship petition be filed? If two or more probate courts have jurisdiction, which is the more appropriate forum to hear the matter? After a guardian has been appointed, can that guardian place the ward in a nursing home in another jurisdiction? Will the conservator be able to transact the ward’s business in another state? If the court in another state appointed the guardian, will its order be given full faith and credit by another jurisdiction? Which court will oversee the guardianship if the ward, guardian, or both move to a different state? What criteria should the court employ to determine if it has jurisdiction to appoint a guardian for an incapacitated person who is temporarily located in the state or for a resident who is now living in a long-term care facility in another state?
