Anti-Assignment Clause

Also called assignment clause, no assignment without consent

A clause letting your counterparty transfer the contract freely while forbidding you from doing the same, which can make your business unsellable.

What it is

An anti-assignment clause governs whether a party may transfer its rights and obligations under the agreement to someone else. In payments contracts, the standard drafting is asymmetric: the processor or acquirer reserves the right to assign freely, including to an affiliate or a purchaser, while the merchant or agent may not assign without consent, and sometimes may not assign at all. For a merchant, the practical consequence appears when the business is sold. If the merchant agreement cannot be assigned, the buyer needs a new merchant account and new underwriting, which is usually workable but should be planned rather than discovered during a closing. For a sales agent or an ISO, the consequence is far more serious. An agent's residual stream is the asset. If the agent agreement forbids assignment, the agent literally cannot sell the portfolio, because the buyer cannot step into the contract. A clause of two lines can convert a saleable asset into a job. The realistic negotiation is not to remove the clause but to make it symmetric in the ways that matter: the right to assign to an affiliate or to a purchaser of substantially all assets, with consent not to be unreasonably withheld. Paired with that, if the counterparty undergoes a change of control, the residual terms should survive unchanged.

Why it matters to your business

If you are a merchant, ask what happens to your merchant account if you sell your business. It is a five-minute question that prevents a closing-week scramble. If you are a sales agent or building an ISO, this is the single clause most likely to determine whether you own an asset or a paycheck. Get the right to assign to a purchaser of substantially all your assets, with consent not to be unreasonably withheld, in writing, before you board your first merchant. Retrofitting it later requires the counterparty to give up leverage voluntarily. This is education, not legal advice; contract terms should be reviewed by an attorney who does payments work specifically.

Where it gets contested

Processors defend broad anti-assignment rights on real grounds. They underwrite the counterparty, they carry compliance obligations for their agents under network rules, and an unvetted assignee is a risk they did not accept. Nobody wants a portfolio sold to an operator the sponsor bank would never have approved. The counter-argument is that the standard drafting goes far beyond that concern. Consent not to be unreasonably withheld addresses vetting. A flat prohibition addresses leverage, because an agent who cannot sell has only one buyer, the processor, and the processor knows it. What is unresolved in practice is enforcement of reasonableness. Consent not to be unreasonably withheld is only as good as the willingness to litigate over it, and most small agents will not. That is why the negotiation matters more than the remedy.

How to check it yourself

Search your agreement for the word assign. Read who may assign, who may not, and whether consent is required and on what standard. If the clause is one-directional with no reasonableness standard, that is your negotiation item.
