The relevant Virginia law can be viewed
here. If I understand it correctly, the required threshold for being eligible for a public defender is an income plus assets of less than 125% the federal poverty level. And while the state cannot force people to sell their homes to pay for a lawyer (not that it would matter in this case, since 14BC is in Barb's name, not Chris's), everything else is fair game.
Also, the state cannot force Chris to represent himself, if he can't afford to pay for a lawyer; either he has to sign a waiver agreeing to defend himself, or the court has to give him a public defender.
