Virginia law allows a designated representative to return an emergency ballot for a voter who is incapacitated or hospitalized. The representative must complete a statement, in which false statement is considered a felony.
The incapacitated voter shall vote the absentee ballot as provided by law and mark it in the presence of the designated representative. The representative shall complete a statement, subject to felony penalties for making false statements pursuant to § 24.2-1016, that (i) he is the representative of the incapacitated voter; (ii) he personally delivered the ballot to the voter who applied for it; (iii) in his presence, the voter marked the ballot, the ballot was placed in the envelope provided, the envelope was sealed, and the statement on its reverse side was signed by the incapacitated voter; and (iv) the ballot was returned, under seal, to the general registrar at the registrar’s office.
