Assignor

An assignor is the party that transfers a right or benefit under a contract to someone else. If a business sells its unpaid invoices to a finance company, the business is the assignor and the finance company is the assignee.

The assignor gives up the entitlement it is transferring but usually keeps any duties it originally promised to perform.

From the Money Master HQ dictionary, founded by Shihan Sheriff (FCMA, VP of Finance at Nomod, CFO at Esanjo Ventures). How these definitions are written.

What it means

Every assignment has two named sides, and the assignor is the one letting go of something valuable in exchange for cash, credit or a commercial favour. A supplier assigning invoices, a tenant assigning a lease and an inventor assigning a patent are all assignors.

The label describes a role in a transaction rather than a type of organisation. The assignor's central obligation is that what it hands over is genuine and enforceable.

It normally warrants that the right exists, that the amount is correct, that no one else has a competing claim over it and that no dispute is outstanding. If any of those warranties turns out to be false, the assignee can usually come back to the assignor for compensation.

Crucially, assigning a right does not release the assignor from its own performance obligations. A contractor that assigns its payment rights still has to finish the building, and a licensor that assigns royalty income still has to honour the licence terms.

Only a novation, agreed by all three parties, moves obligations away. Where the assignment is with recourse, the assignor also retains the credit risk on the underlying payer.

That means if the customer fails to pay, the assignor must make the assignee whole, often by substituting another receivable or repaying the advance. This retained exposure is the main reason such transactions are accounted for as borrowing rather than as a sale.

The assignor also has a practical duty to cooperate after the transfer. That usually means signing notices, redirecting any payments received in error and passing on correspondence about disputes.

Assignees frequently write these cooperation obligations into the agreement because their ability to collect depends on them. For the assignor the commercial calculation is nearly always about time and certainty.

Giving up a future entitlement worth $100,000 in ninety days in exchange for $92,000 today makes sense if that cash prevents a shortfall, funds a profitable order or avoids more expensive borrowing. The discount accepted is effectively the price of turning a promise into money now.

In practice

Real-world examples.

1

Example

A marketing agency acts as assignor when it transfers $180,000 of client invoices to a lender in return for an immediate advance. It warrants that the work was delivered and accepted, and it remains responsible for handling any client complaints about the campaigns.

2

Example

A retail chain closing a branch becomes the assignor of the shop lease, transferring the remaining term to an incoming operator. The landlord requires the assignor to guarantee the new tenant's rent for the first two years, so the exit is not entirely clean.

3

Example

A biotechnology founder is the assignor of a patent transferred to the company she has established, in return for shares. She warrants that she is the sole inventor and that no employer or university has a competing claim to the invention.

Case study

Seen in the real world.

Vantage Print Group is an invented business used purely as an illustrative example. Facing a slow quarter, it assigned $420,000 of invoices to a finance house and received an advance of $336,000, warranting in the agreement that every assigned invoice related to goods already delivered and accepted.

One customer later refused to pay $60,000, arguing that a third of the order had arrived damaged and had been rejected before the assignment took place. Because Vantage had warranted that the invoices were undisputed, the finance house required the company to substitute a clean invoice of equal value.

The fictional finance director responded by changing the internal process so that only invoices past the customer's acceptance window could be assigned. It cost a few days of funding speed, but it removed the risk of Vantage breaching its warranties as an assignor and having to fund substitutions at short notice.

Watch out

Common mistakes.

  • Believing that assigning payment rights ends the assignor's involvement, when performance obligations and warranties usually continue unchanged.
  • Assigning invoices that are subject to a live customer dispute, which breaches the standard warranties an assignor gives.
  • Confusing the assignor with the assignee in documents and payment instructions, which can misdirect funds and undermine a notice of assignment.

Questions

People also ask.

Does the assignor stay liable if the customer never pays?

Under a recourse arrangement, yes, the assignor must repay or replace the amount, whereas a non-recourse deal shifts that credit risk to the assignee.

Can an assignor assign the same right twice?

It should not, and doing so is usually a breach of warranty and potentially fraud, which is why lenders register their security and check for existing charges.

Does the assignor need the customer's permission?

Only if the underlying contract restricts assignment, in which case written consent must be obtained before the transfer is effective.
