Is it permissible for a wife to stipulate to her husband that the marriage be on paper only—so that he neither approaches her nor demands his marital rights from her—and is it permissible for someone to bear witness to this condition or for it to be written in the contract?

A woman's stipulation in the marriage contract that her husband not approach her sexually is a void condition, as it contradicts the essence of the contract. However, the contract itself remains valid. The husband may waive his right to intercourse after the contract, but this waiver does not relinquish the right forever. Rather, either party can retract their waiver and demand their right at any time. Such an agreement does not affect the validity of the marital bond.
