guardianship of mentally ill sibling in washington stateThe sibling I am referring to is an older brother who is both physically and mentally disabled/ill. I have found that he is making inquiries into getting a car, loans for higher education and other similar things marketed by telemarketers and through the internet. The biggest problem is that he has no income other than ssdi. In the past when he's gotten caught up with the telemarketers, he has defaulted on payment of services since he has no way to pay them back. He says he understands the legal implications but he still takes the bate and gets into trouble. Is it time for legal guardianship to save this person from themselves? If so, what is the process. Thanks in advance for any assistance.
