Can social security be garnished for back pay or non payment in a divorce case/agreement

Generally, Social Security benefits are exempt from execution, levy, attachment, garnishment, or other legal process, or from the operation of any bankruptcy or insolvency law.  The exceptions are that benefits are subject:

(1) to the authority of the Secretary of the Treasury to make levies for the collection of delinquent Federal taxes and under certain circumstances delinquent child support payments; and

(2) to garnishment or similar legal process brought by an individual to enforce a child support or alimony obligation.
