Are electronic signatures legally binding?

Yes. In the United States, electronic signatures are legally binding under the ESIGN Act (15 U.S.C. §7001) for interstate commerce and under state UETA laws; New York applies its ESRA statute. Ensure intent, consent, attribution, and record retention.

Do contracts require notarization to be valid?

Generally no. Most commercial contracts do not require notarization, but certain instruments (deeds, some powers of attorney) may. Notarization can aid authentication but is not a universal validity requirement.

How do I correct an error after signing?

If an error is substantive, prepare an amendment or correction signed by all parties. Minor clerical corrections can be addressed by mutual written agreement to avoid challenges to enforceability.

Can I revoke or cancel an agreement after signing?

Termination and cancellation depend on the contract terms. Review termination clauses and notice requirements; unilateral revocation without contractual grounds may breach the agreement.

What records should I keep after execution?

Retain executed agreements, SOWs, invoices, and performance reports. Follow IRS retention rules (IRC §6501(a)) and industry rules such as HIPAA retention where applicable.

When is attorney review recommended?

Seek legal review for substantial budgets, unusual IP assignments, complex indemnities, or cross-border or regulated-industry campaigns to manage legal and compliance risk.

What the Advertising Services Agreement Covers

An Advertising Services Agreement is a written contract between an advertiser (client) and a service provider (agency, media buyer, or freelance specialist) that defines scope of work, deliverables, payment, schedule, intellectual property rights, confidentiality, performance metrics, termination rights, and dispute resolution. It allocates responsibilities for campaign creative, media buys, tracking and reporting, and any third-party costs. The agreement may also include warranties, indemnities, data handling terms, and a governing law clause to specify which state law applies. Electronic signatures executed under ESIGN or UETA are generally acceptable to form a binding contract.

Why use a formal Advertising Services Agreement

A clear written agreement reduces misunderstandings, sets measurable expectations for campaign performance and billing, protects intellectual property and client data, and provides a contractual basis for dispute resolution and termination.

Who typically completes this agreement

Marketing teams, agency account leads, independent media buyers, and procurement or legal departments commonly use Advertising Services Agreements to manage risk and clarify obligations.

Small agencies and freelancers who need to formalize deliverables, payment schedules, and usage rights for creative work.
In-house marketing teams that hire external vendors for media buys, creative production, or programmatic services.
Legal or procurement teams who review terms for liability, data handling, and IP assignments before vendor onboarding.

Use of this agreement helps align expectations across stakeholders and creates a record suitable for electronic signature and long-term retention.

Typical signatories and their roles

Agency Executive

An agency executive (CEO, COO, or authorized account director) signs on behalf of the provider to accept scope, billing, and IP terms. Their signature binds the agency to deliverables, payment terms, and confidentiality obligations for campaign staff and subcontractors.

Client Signer

A client-side authorized representative (CMO, VP Marketing, or procurement officer) signs to accept the scope, budget, and billing schedule. The signer should have authority to commit the advertiser to payments and to approve third-party media spend.

Core clauses to include in a professional agreement

A complete Advertising Services Agreement clarifies performance, money, timing, and protection for both parties. The following clauses are commonly included and should be tailored to the project.

Parties

Scope of Work

Detailed deliverables, creative specifications, media channels, campaign objectives, reporting cadence, and approval processes.

Payment Terms
