Can credit card creditors garnish my 92 year old mothers social security check for debt owed?
My mother is 93 yrs old, and credit card companies are now going to try and sue her for non- payments on her cards. She has been in and out of the hospital and nursing home for 2 years now. She was released from the nursing home again in July of 06, and I am now taking care of her at my home. She receives $1235.00 a month on social security and helps me with food, utilities, telephone, etc. as I am also on supplement social security due to ill health. She also has dementia and severe degenerate bone disease, and can hardly walk anymore. She also has heart problems and had a pacemaker put in. She does not make that kind of money to pay back the credit card debts that she owes, and we are now getting calls from debt collectors about suing her and garnishing her social security to pay these debts back. I was informed to get a per-se bankruptcy form from a library of law or some where, where they have these forms, and fill it out for her. I do not understand all of this, and how to go about helping her. My mother can not even leave the house anymore as she falls a lot, etc. so there would be no way she could appear in court on this. I would appreciate any advice or help you can give me.
