Which of the following is NOT considered a writ of attachment?

A writ of attachment is a legal order that allows a party to seize a person's property to secure a judgment. In this context, a detainer does not fall under the category of a writ of attachment. A detainer is essentially a request to hold an inmate in custody for another jurisdiction or a pending matter, but it does not involve the seizure of property to ensure the execution of a judgment.

Conversely, a convict witness and resident witness pertain to individuals called to provide testimony in court regarding a legal matter. A bench warrant, on the other hand, is issued by a judge to order the arrest of a person who has failed to comply with court orders, which constitutes an enforcement mechanism that can relate to judgments but does not involve attachment of property in the traditional sense.

Thus, the correct answer, provided as “detainer,” is not classified as one of the typical writs of attachment because it pertains more to custody and holding rather than the seizure of assets or property.
