How Can I Legally Protect Myself From Having To Deal With My Parents I Am No Contact With When They May Need Medical / Living Care And When They Die?

Location: Lakewood, Colorado

A little context....I have been no contact with both my parents, brother and the majority of extended family between 3 to 7 years depending on the person. At this point I have no intention of reestablishing contact or relationships with any of my family ever again. My mom is in her late 60s and my dad is in his mid 70s. They are divorced from one another and my mom lives in Florida and my dad lives in Pennsylvania. I live in Colorado and my brother lives in Virginia and we are in our early 30s to mid 30s.

I am very nervous about my parents aging. There is a good chance that in the near future one or both of them will need medical care and/or assisted living care. I don't know what either of their finances look like, what their wishes / plans are (if they even have any) whether its hiring someone to come in their homes, go into assisted living care or expecting my brother and I to financially support and care for them. I also have no idea what all is in their wills / other legal documents when they die, what their death wishes are and who they expect to handle whatever they leave behind upon their deaths. None of this was ever discussed with me when I had a relationship with both of my parents and brother.

I do not wish to take care of them (in person or from a far), financially support them if needed or have any authority with medical decisions or other life decisions they have to make if that day ever comes. I also do not wish to be involved or have any authority in making post death arrangements for them, be in their wills to receive any of their money, land or possessions they leave behind or possibly be an executor of their wills, cleaning out / selling their properties, etc....

I have no idea if my parents and brother have already discussed this and have chosen and/or taken legal action to exclude me but if I were a betting person I would say no. I am SO nervous that they and/or my brother will try to demand help when these days come and that I could be legally required too comply. What are my rights here? Is there anything I can serve my parents stating my wishes and requesting to have their paperwork changed to exclude me if they have not done so already? Can they retaliate legally if I ignore their wishes? If there is anyone who has more insight on these matter, I would love your advice! Thank you in advance!
