What is the legal ruling regarding the error in writing the amount of the deferred dower (mu'akhkhar al-sadaq) in court as 19 mithqals of gold instead of the 35 mithqals agreed upon in the initial marriage contract, and can the amount in the court contract be increased to 35 mithqals?

An error in writing the deferred dowry (mu'akhkhar al-sadaq) when registering the contract in court is not taken into consideration. Rather, what is considered valid is what was agreed upon between the spouses. Therefore, the remaining deferred dowry owed by you is 35,000, not 19,000, unless the wife waives part of her right.
