Where the contract is joint on the part of the promisees, all must join in suing upon it.29 Even a disclaimer by one, if without the assent of the promisor, will not entitle the others to sue alone.30 If one of them is not joined as a plaintiff, the defendant may plead in abatement; but failure to do so will not constitute a waiver of the defect.31
