We live in Maryland State and we like to our relative to deal with buying residential real property for us in the California State. We like to execute Power of Attorney assigning our relative as our attorney.
Q1) Could we use Maryland State power attorney or California State one, sign it and Notarize in Maryland State and send it to California. Is there a special type of power of attorney for this purpose?

Q2) Can both I and my spouse sign on the same power of attorney do we need to send separately two powers of attorney tot he same person as we like to property in both our names.

Your help answering these question is highly appreciated.
