A marketing agency contract dispute is a disagreement over what the agreement requires, what has been paid, or how the relationship ends. KEW Legal acts as outside general counsel for business owners and investors across Miami-Dade and South Florida. This page explains the terms that matter most, how emails and verbal deals can count, and what a practical path forward can look like in Florida.
What a Marketing Agency Contract Dispute Involves
A marketing agency contract dispute is a disagreement between a business and its marketing, advertising, digital or creative agency. The fight is usually over what the contract requires, what has been paid, or how the relationship ends.
Agency work comes in several forms:
- Retainers: a monthly fee for ongoing services.
- Statements of work: a fixed scope for a campaign, website or content series.
- Media buying: the agency places paid ads and bills for the media spend.
- Performance deals: part of the fee depends on measured results.
This page is for brands that hire agencies. It is also for agencies that serve clients in Miami-Dade and Broward County. These disputes often start as business problems. A missed deadline or a surprise invoice becomes a legal question once someone asks what the signed paper says.
If your agency has quit delivering, is holding your ad accounts, or left an invoice unpaid, our team can review the contract with you. Reach out to KEW Legal today. Talk it through with our team — the first consultation is free, confidential, and carries no obligation.

Contract Issues We Handle for Agencies and Clients
The terms that most often shape these disputes are scope, payment, ownership, termination and confidentiality. Each one decides who owes what when a relationship goes wrong.
- Scope and change orders: what was included, what was added informally, and how extra work gets billed.
- Payment: unpaid retainers and invoices, disputed hours, markups and pass-through media spend.
- Ownership: creative, ad accounts, domains, social pages, data and analytics access.
- Termination and notice: minimum terms, cancellation fees and how to exit without breaching the contract.
- Restrictive clauses: exclusivity, confidentiality and non-solicitation terms that limit who can work with whom later.
- Liability and indemnity: limitation-of-liability and indemnity language, and how courts read it.
Florida limits restrictive covenants. A court will not enforce one unless it is in a writing signed by the person it binds. If a restraint is overbroad, overlong or not reasonably necessary to protect a legitimate business interest, a court must modify it and grant only the relief reasonably necessary to protect that interest (Fla. Stat. § 542.335).
When a Verbal Deal or Email Thread Can Still Matter
A verbal deal or email thread can still matter, even when nothing was signed. Many agency relationships begin with a phone call, a proposal email or an approved estimate.
- Electronic signatures count. Unless the law says otherwise, an electronic signature has the same force as a written one (Fla. Stat. § 668.004).
- Verbal terms may be enforceable. Whether they are depends on their terms and what can be proven.
- Deadlines come from statute. Florida sets time limits for filing lawsuits in its statutes of limitations, and the applicable deadline depends on the type of claim.
- Short deadlines in contracts are void. A clause that sets a shorter time to sue than the statute allows has no effect (Fla. Stat. § 95.03).
Start preserving the record now. Collect proposals, approvals, invoices and messages before the dispute grows. Payment records and written approvals show what each side agreed to and paid.
How the Dispute Process Works
Most agency disputes move in stages: document review, a written demand, negotiation, and then mediation or court if needed. Each stage depends on the documents and on how the other side responds.
- Intake. A confidential review of the contract, statements of work, invoices and communications.
- Analysis. Identifying which terms control, which are unclear, and what each side can prove.
- Demand and negotiation. A written demand, a response to the other side’s claims, and a settlement proposal.
- Mediation or arbitration. Used when the contract requires it or both sides agree. Arbitration agreements in writing are generally enforceable (Fla. Stat. § 682.02).
- Litigation. Filing, discovery and court proceedings in Florida courts, with a clear view of time and cost.
Fees follow a default rule. If a contract lets one side recover fees for enforcing it, the court may also allow fees to the other side when it prevails (Fla. Stat. § 57.105). This applies to contracts entered into on or after October 1, 1988.

Questions Business Owners Ask About Agency Disputes
Here are short answers to common questions about agency disputes.
Can I end my agency contract early?
It depends on the termination clause, the notice it requires, and what both sides did in practice. Read the notice terms first.
Does my agency own the ads it created for me?
Ownership depends on the contract language and on whether the work was paid for in full. Check the ownership clause before you assume either way.
Can I withhold payment over a disputed invoice?
Withholding payment without a written explanation can create problems of its own. Raise the objection in writing and keep a record.
What if we never signed anything?
Emails, proposals, approvals and payment records can still show the terms you agreed to. Gather them now.
Is a free consultation available?
Yes. The first consultation is free, confidential, and carries no obligation to continue.
