MEANING OF ASSIGNMENTS.—Much of the difficulty regarding assignment of contracts is due to different meanings which may be attached to the word assignment. When property is assigned the assignee becomes the owner in every sense, if the person from whom he took the assignment had a valid title. This is not true of the assignment of contracts. By the common law, contract rights or "choses in action," as they are termed in law, were not assignable, the reason being that one who contracted with A, cannot without his consent become bound to B.
POWER OF ATTORNEY TO COLLECT A CLAIM.—Though when a man had a contract right he could not by common law make B in a complete sense the owner of the claim, he could give B a power to collect the claim as his, A's, agent, and authorize him to keep the proceeds when the claim was collected. It long ago became established that when an owner of a claim purported to make an assignment of a claim he thereby gave the assignee the power to enforce the claim in his stead, and this power given the assignee is irrevocable.
EFFECT OF ASSIGNMENT OF RIGHTS.—It may be supposed that the effect of an assignment of a right, though the result may be worked out by treating the assignee as an agent or attorney of the assignor, is the same as if the assignee were fully substituted in the position of the assignor as owner of the claim, but this is not quite true. Assuming that the claim is not represented by negotiable paper, the legal owner of the claim is still the assignor. This is shown by the fact that if the debtor pays the assignor in ignorance of the assignment, the debt is discharged and the assignee can only go against his assignor for the latter's fraudulent conduct in collecting the claim after having assigned it. So, too, if the assignor makes a subsequent assignment, this subsequent assignee also has a power of attorney to collect the claim and keep the proceeds; so that if the second assignee in good faith collects the claim in ignorance of the prior assignment, he can keep what he has collected; nor is the debtor liable to the first assignee who must as before seek redress from his assignor. It is, therefore, always important for the assignee of a non-negotiable chose in action to give immediate notice of his assignment to the debtor. If after such notice the debtor should pay the assignor or a subsequent assignee, such payment would not discharge the debtor, and the first assignee could collect the claim from him.
NON-ASSIGNABLE RIGHTS.—Rights cannot be assigned which are personal in their nature. The one who has contracted to paint a picture cannot delegate the duty to another, no matter how skillful. One who has a right to the personal services of an employee cannot assign that right to another. A publisher who has a right to publish all books written by a certain author cannot assign his right to another publisher.
ASSIGNMENT OF DUTIES.—The duties under a contract are not assignable under any circumstances. That is, one who owes money or is bound to any performance can not by any act of his own or by any act in agreement with any other person except his creditor, divest himself of liability and substitute the liability of another. This is sufficiently obvious when attention is called to it; for otherwise debtors would find an easy practical way of escaping from their debts by assigning the duty to pay to irresponsible persons. But the principle is not always recognized. A person who is subject to a duty, though he cannot escape liability, may delegate the performance of his obligation provided the duty is of such a character that performance by an agent will be substantially the same thing as performance by the obligor himself. Thus if a contractor engages to build a house, he may delegate the actual building to another, but he cannot escape responsibility for the work. One who owes a mortgage may delegate the payment of the mortgage to a purchaser of the land who assumes and agrees to pay the debt. If the purchaser of the land actually pays, the debt is discharged; but if he fails to do so, the mortgagee may sue the original mortgagor and the latter will be obliged to bring another action against the purchaser who promised to pay the debt and failed to do so. So where a partnership is changed and a new firm formed, it is very common for the new firm to assume the obligations of the old firm.
ORIGINAL DEBTOR NOT DISCHARGED UNLESS THERE IS A NOVATION.—Though a creditor cannot be deprived of his right against his original debtor without his consent, he may consent. If he does thus consent to take in lieu of the obligation of his original debtor that of the person who assumed the debt, what is called a novation is created. That frequently happens where a new firm succeeds an old one. The new firm goes on dealing with the old creditors, and they impliedly, if not expressly, assent to taking the new firm instead of the old firm as a debtor. But in order to make out a novation you have got to find as a fact that the creditor agreed to give up his right against the old debtor. If the creditor does not assent to a novation then the situation is that the creditor retains his claim against the old debtor, but the person who has assumed the debt has contracted to pay that debt. If he keeps his contract he will pay it and the debt will be cancelled. If he does not keep his contract the creditor will sue the original debtor and the original debtor will sue the man who assumed the debt.
ASSIGNMENT OF BILATERAL CONTRACTS.—In bilateral contracts each party is under a duty to perform his promise, and also has a right to the performance of the other party. If an attempt is made to assign such a contract the effect is this: the assignor delegates to the assignee the duty of performing the assignor's promise, but the assignor himself still remains liable if his agent, the assignee, fails to carry out the duty. Further, the assignor authorizes the assignee to receive the payment or performance due from the other party to the contract and to keep it for himself.
WHAT AMOUNTS TO AN ASSIGNMENT.—No particular words are necessary to constitute an assignment. Any words which show an intention that another shall be the owner of a right are sufficient to constitute the latter an assignee. Especially it should be observed that an order directed to a debtor of the drawer ordering him to pay the debt to a named payee, is an assignment of the debt when delivered to the payee. This case must be sharply distinguished from a bill of exchange or check. A bill of exchange or check is an order to pay a certain amount unconditionally, irrespective of the existence of any particular fund. It is only an order to pay from a particular fund, that is, an order which is conditional expressly or impliedly on the existence of that fund, which constitutes an assignment.
PARTIAL ASSIGNMENT.—A creditor may not only assign his whole claim to an assignee, but he may assign part of it. Such a partial assignment authorizes the assignee to collect the portion of the claim assigned and keep it for himself. But the debtor is not bound to pay the claim piecemeal; he may insist on making but a single payment unless his contract with his creditor provides otherwise. A bank in accepting a deposit contracts to pay that deposit in such amounts as the depositor may indicate on the checks drawn by him, but an ordinary debtor who owes $100 cannot be required to pay in such amounts as his creditor may see fit to demand. For this reason a few courts hold that even if the debtor has notice of a partial assignment, he may pay the whole debt to the original creditor though that results in defrauding the partial assignee. Most courts hold, however, that the debtor when notified of the facts cannot do this, and if he objects to paying fractional parts of his indebtedness he must pay the whole sum into court to be distributed by it among the parties entitled. So, on a question of this character, the local statute should be examined.
ASSIGNMENT OF FUTURE CLAIMS.—Assignments of future claims, as well as of existing claims, may be made, but there are in many States some special provisions of statute law in regard to assigning future wages. Such assignments must often be recorded, and there are certain other special statutory provisions in regard to them. The assignment of future debts is also subject to this qualification: The law does not allow the assignment of a future claim unless the contract or employment out of which the claim is expected to arise has already been made or is already in existence.
