Can you disinherit a disabled adult child in Arizona

Good Morning, Ms. Crawford: Can a parent disinherit a disabled adult child in Arizona? In short, yes. People are generally free to leave their material wealth to whomever they want when they pass, or, conversely, to disinherit whomever they want. Absent some other agreement, court order, or contract to provide continued support the father is free to disinherit his son. However, disinheriting a biological child generally means that the decedent needed to have an estate plan (will or trust-based) wherein the decedent specifically names the child to be disinherited and that said child is being disinherited. Otherwise, your son can petition the court for his share of his father's estate, if there is anything to distribute. Do you know if the father had an estate plan?
