Can a wife sale and sign bill of sale on vehicle while husband is in jail?

Yes, a wife can sell and sign a bill of sale for a vehicle while her husband is in jail, provided she has legal authority to do so. This authority typically comes from being listed as a co-owner on the vehicle's title or having a power of attorney that grants her permission to act on her husband's behalf. It's important to check state laws and the vehicle's title requirements to ensure the sale is valid.
