At what point can the sheriffs office assist in repossession?

The sheriff's office can't act without a court order. This is not especially difficult to obtain if the lienholder can show that the lessee (the person who obtained the loan for the property) has defaulted on the loan contract by not making their required payments. Once the judgment has been issued by the court, the lienholder can request the sheriff's office to assist in repossession. The sheriff's office may charge a fee for this service.

Another View: Define "assist." If the SO receives a court order to "assist" in the repossession, that is what they will do. . . ASSIST. They will not physically remove the items by force of arms, or tow a vehicle, nor will they assist in hauling out the lienholders belongings, or the items referred to in the order.

They will be present only to ensure that no breach of the peace takes place. PERIOD
