Can signing a quick claim deed to a lifetime estate hurt someones eligibilty to medicaid benefits in GA

It's called a "quit claim" deed, not a quick claim, by the way, because the person signing it is giving up (quitting) his or her claim to the real estate involved. If your mother is receiving Medicaid or SSI, or some similar, needs-tested benefits, then yes, signing a quit claim deed can seriously affect her eligibility because she is giving away an asset to which she would otherwise be entitled. Before she signs anything, she should consult her own attorney; preferably an elder law attorney who is knowledgeable about the particular benefits she is receiving.
