Del. Code tit. 28, § 1545

A player shall protect a held hand by holding onto it above the table or by placing 1 or more chips on it. A protected hand may not be ruled dead by accidental contact with discards unless it is impossible to reconstruct completely. A player who has a protected hand taken in by the dealer or fouled by discards through no fault of the player is entitled to a refund of all of the chips the player put in the pot in that game.
