can a collection agency garnish your wages in texas
No. In the state of Texas a creditor cannot garnish your wages no matter how much is owed.
The employer does not garnish your wages, they simply obey the order of garnishment. And, yes, the electric service provider can garnish your wages once they have obtained a judgment.
no but they can sue you and a judge can in the US anyway
No They can not.....you are in one of the safe states. Texas and North and South Carolina along with Pa are safe states that can not garnish wages.
In Indiana, a credit card company can only garnish wages if there has been a judgment against you. If they sued you, and you lost or did not show, and the Judge determined you owed, they can garnish you. They can not do it on their own.
