I have a temporary order of protection against the abuser. Can his/her gun be taken away?
Most likely no. Nothing in South Carolina law specifically says that someone with a temporary order of protection against him/her cannot have a gun.* You can ask the judge to write in your temporary order that the abuser cannot have a gun while you are waiting for a full court hearing. If the judge sees the abuser's firearm as a serious enough threat, perhaps the judge might decide to write this in.
* See S.C. Code §§ 20-4-60; 16-25-30
