As used in this part, unless the context otherwise requires:
1. “Emergency” means a circumstance that likely will result in substantial harm to a respondent’s health, safety, or welfare, and for which the appointment of a guardian is necessary because no other person has authority and is willing to act on the respondent’s behalf.
2. “Home state” means either of the following:
a. The state in which the respondent was physically present, including any period of temporary absence, for at least six consecutive months immediately before the filing of a petition for a protective order or the appointment of a guardian.
b. The state in which the respondent was physically present, including any period of temporary absence, for at least six consecutive months ending within the six months prior to the filing of a petition for a protective order or the appointment of a guardian.
3. “Significant-connection state” means a state, other than the home state, with which a respondent has a significant connection other than mere physical presence and in which substantial evidence concerning the respondent is available.
