Property buy-out...

When my mother passed away my 4 siblings n I became owners of the house my father left her when he passed. I have no attachment to the house nor can I live there for health reasons, so since there's been feuding amongst my siblings I just want what I'm entitled to since I have no relations to them in going on 5 yrs the right thing would be to buy me out so I can put them behind me n go on with my life. The problem is that the house is in Puerto Rico n the laws I think r different from here. So my question is, are there lawyers in NY that would handle this issue. I'm terminally ill n need to do this now while I'm doing ok... any referrals will sincerely be appreciated. Retired n on Social security here.
