Section 44

Any one of joint promisors may be compelled to perform; each promisor may compel contribution; sharing of loss by default in contribution

When two or more persons make a joint promise, the promisee may, in the absence of express agreement to the contrary, compel any one or more of such joint promisors to perform the whole of the promise.

Each of two or more joint promisors may compel every other joint promisor to contribute equally with himself to the performance of the promise, unless a contrary intention appears from the contract.

If any one of two or more joint promisors makes default in such contribution, the remaining joint promisors must bear the loss arising from such default in equal shares.
