English to Spanish Law/Patents Law (general) Medical terms used during legal proceedings.

I would like to know the best translation of this phrase from American English into Latin American Spanish.

Colleagues from Spain, feel free to send me your suggestions as well.

It's a translation of a document about public health meeting. Is okay to translate it as
poder legal para la atención médica?

This is for Latin People living in The United States of America and Americans readers.

Here is the full paragraph for your review:

The New York City Council member XXXXXX,
is collaborating with local law schools and pro bono
attorneys to offer free estate planning information
and consultations, as well as the possibility of
having estate planning documents (such as a
last will and testament, power of attorney, and/
or healthcare proxy) prepared free of charge for
qualified participants. These documents allow you
to express your wishes about how you want your
healthcare and property to be handled when you are
unable to speak for yourself""
