My father has no living trust or will in testament. Hospital social worker wants me, son, to apply for medi-cal and Social security on his behalf. Speaking to hospital financial counselor, I need financial records to apply. By applying for medi-cal or Social Security forms, does this hold me financially responsible or obligated in any way by signing? If I obtain power of attorney, can hospital seek my assets for payment? What does power of attorney mean? Does it only make me responsible to have his affairs in order or am I financially responsible in anyway? Please HELP? Do I need to obtain a lawyer? Probate? What happens to his material possessions if he passes? Car loan, credit cards, etc?
