Living wills & Power of Attorney
My parents are leaving the country on 7/19/2001 for 6 months. Their house is on market for sale. Will Power of Attorney allow my oldest sister to act & sign all legal contract on my parents’ behalf? And what is the correct legal procedure/form for my parents & sister to file before they leave the State.

Please also instruct us on which legal forms to make my oldest sister have the ability to make all finance & health decision in case my parents aren’t capable of making their own decision.

Thank you in advance for your assistance.

Dual Powers of Attorney
My mother has Durable Power of Attorney over my Alzheimer’s-diagnosed grandmother. My mother has now moved out of the state and we are seeing a need for me to have decision making authority regarding my grandmother’s healthcare. Since my mother holds the POA, can she designate me as a ”co” Power of Attorney?
