37Obligation of parties to contracts.

The parties to a contract must either perform, or offer to perform, their respective promises, unless such performance is dispensed with or excused under the provisions of this Act, or of any other law.
Promises bind the representatives of the promisors in case of the death of such promisors before performance, unless a contrary intention appears from the contract.
