If one brother wants to give up his share of the house, he can transfer his share to another person and go to the bank to go through the formalities of changing the repayment person.
Giving up property rights has nothing to do with whether the mortgage is paid off. The abandonment of housing property rights requires notarization, and lawyers can also be entrusted to testify.
Mortgage, also known as mortgage loan, means that the buyer fills in an application for mortgage loan to the bank and provides legal documents such as ID card, income certificate, house sales contract and guarantee letter. The bank promises to grant loans to the buyer after passing the examination, and handle the notarization of real estate mortgage registration according to the house sales contract provided by the buyer and the mortgage loan contract signed between the bank and the buyer. The bank directly transfers the loan funds to the sales unit in the bank within the time limit stipulated in the contract.
