Novation and Assignment Move a Contract in Different Ways

Businesses change hands and contracts have to follow. Two mechanisms do that work, and they are not interchangeable.

Assignment moves the benefit only

An assignment transfers the right to receive performance from one party to another. The right to be paid, or to receive goods, moves across.

The burden does not travel with it. The original party remains liable for the obligations it promised, even after the benefit has gone elsewhere.

This is why an assignment can usually be done without the other side's agreement, subject to the contract's own restrictions. Nobody is being asked to accept a new debtor.

Novation replaces a party

A novation extinguishes the original contract and creates a new one on the same terms with a different party in place. The outgoing party is released.

Because someone is being released and someone new is being accepted, every party must agree. A novation cannot be done unilaterally.

That consent requirement is the practical difficulty. The remaining party gains a right to negotiate, and often uses it.

Why the difference is discovered late

Both are frequently described loosely as a transfer, and paperwork sometimes uses the wrong word. The consequences only surface when something goes wrong afterwards.

A seller who assigned rather than novated can find itself pursued for failures committed by the buyer after the sale. Indemnities between them may help commercially, but the original counterparty is entitled to look at the original promisor.

Restrictions written into the contract

Many agreements prohibit assignment without consent, sometimes with consent not to be unreasonably withheld. Some prohibit it outright.

The effect of breaching such a clause varies: in some systems the purported assignment is ineffective, in others it is a breach that gives rise to damages. This is one of the areas where jurisdictions diverge sharply.

Change of control provisions do related work by treating a share sale as a trigger even though no contract moved. They exist because the counterparty may care who ultimately owns the business.

Related mechanisms that look similar

Subcontracting delegates performance without moving the contract, so the original party still answers for the result. It is a third pattern often mistaken for the other two.

Statutory transfers can also move contracts automatically in certain situations, notably in some employment and insolvency contexts. Whether any of these routes fits a particular transaction is a question for a lawyer familiar with the governing law.
