Q. Could SSI and Social Security Disability Insurance be garnisheed, if so what percentage?
A. Supplemental Security Income (SSI) benefits cannot be garnisheed.
Social Security benefits can be garnisheed, but Federal law prohibits garnishment of Social Security for any purpose other than child support, alimony or an unpaid debt to the Federal government. However, banks may be required by state law to freeze accounts when a garnishment order is filed.
If your account is garnisheed for other than allowed purposes, you will be able to recover your Social Security benefit, but you may temporarily lose access to your benefit.
You might want to talk to your own bank about its procedures when a garnishment order is received.
