Answer:
Alienable clause
Explanation:
Alienable clause is made to prevent the borrowers to transfer their responsibility to another person without the lender's permission.
Basically, as soon as the property is sold, the borrowers will be legally required to pay their loan to the lenders. By enforcing this, the lender will obtain financial protection and reduce their risk. Currently, almost all mortgages that available in the market will require this clause within the contract.
