Can wages be garnished from a Social Security Disability or SSI check?

My Girlfriend won her lawsuit against a friend who stole about $1,000 worth of her things while staying in her home. The theft and value was proven.

The defendant has seven days to return the items which she claims she has sold, given away, thrown away or destroyed out of malice. If she does not return the things, we will be granted access to the home to retrieve the stolen property or be granted financial compensation.

Since she has probably hidden or destroyed the property, my GF will be granted financial compensation.

Often times, however, people claim they cannot pay for the damage they do, even out of willful malice—even when they know the consequences. They are that brazen and flagrant.

So, therein is my question. Can SSI or Disability wages be garnished— say, $50 or $100 a month? Can she do this willful damage flagrantly and openly and hide behind her lack of ability to pay for what she’s done?
