The TSA dispute resolution process is a ladder, not a courtroom.

Notice provisions and the formal trigger.

Every TSA dispute starts with a notice. The notice provision in the agreement defines who serves it, how it gets served, where it goes, and what content the notice has to include. Most TSAs require written notice that identifies the disputed service, the dollar amount in question, the contractual basis for the position, and the requested remedy. Email notices are usually permitted with a confirmation step. Postal mail notices remain the safe default for material disputes.

The clock starts running on the notice date. Most TSAs allow a defined cure period of 10 to 30 business days before the matter escalates to governance. The buyer side review during pre signing confirms the cure period is reasonable given the operating risk. Short cure periods favor the party that brings the dispute. Long cure periods favor the party that is in breach. The buyer benefits from short cure periods for seller breaches and long cure periods for any allegation against the buyer.

Documentation discipline starts at the notice stage. Every disputed service has a service catalog reference. Every disputed invoice has a line item reference. Every disputed SLA breach has data and timestamps. The buyer side team builds a dispute file from Day One of the TSA so that when the notice goes out, the supporting record is already complete. Sellers who get a well documented notice resolve disputes faster because they cannot stall on facts.

Service continuity language in the notice provision matters. Most TSAs require both parties to continue performing under the contract during the dispute. The buyer keeps paying contested invoices into an escrow or pays them under protest with reservation of rights. The seller keeps providing the contested services. The discipline keeps the carve out running while the parties argue.

Operating level escalation and the workstream lead conversation.

The first escalation tier sits inside the operating layer. Workstream leads on each side meet within five business days of the notice to walk through the facts. The conversation is documented but informal. Most disputes resolve at this tier because they reflect operating misalignment rather than substantive disagreement. The buyer side team prepares the operating walkthrough carefully because tone at this stage shapes whether the dispute settles or hardens.

Common operating tier disputes involve service catalog interpretation, scope drift, invoice line items, SLA measurement methodology, change request handling, and pass-through cost validation. Each category has a typical resolution pattern. Service catalog interpretation usually resolves to the written words of the contract. Scope drift resolves to documented change requests. Invoice line items resolve to evidence of service delivery. SLA breaches resolve to data, with both sides agreeing on a measurement standard.

The buyer side advisor sits with the buyer's workstream lead in the operating tier discussion. The advisor knows the precedent across similar deals and the seller's typical positions. The buyer's workstream lead carries the relationship credibility and the operating context. The combination gets a fair settlement faster than either party alone.

If the operating tier does not resolve the dispute within the agreed window (commonly 10 business days), the matter escalates. Both parties sign a brief escalation memo that summarizes the issue, the positions, and the unresolved questions. The memo travels with the dispute up the ladder so each subsequent reviewer starts with a documented record.

Governance committee review and the executive escalation.

The governance committee is the second escalation tier. The committee meets monthly under standard TSAs but a disputed matter can trigger an additional session. The committee usually includes the buyer's TSA program lead, the seller's TSA program lead, the buyer's CIO or CFO, the seller's equivalent, and any required workstream leaders. The committee reviews the escalation memo, hears each side, and seeks a settlement.

The committee operates on a defined timeline. Most TSAs give the committee 15 to 30 business days to resolve a referred matter. The committee can call for additional information, can ask the workstream leads to refine their positions, and can settle the dispute on terms the workstream leads cannot offer. The committee has the authority to grant credits, waive contested charges, agree change orders, and reset SLAs.

Material disputes escalate above the governance committee to the executive sponsors. The buyer's operating partner or CFO and the seller's chief commercial officer or CFO sit across from each other. This tier sees fewer disputes but the disputes are large. The executive sponsors have the authority to settle without going to formal proceedings. The buyer's discipline at this tier is to demonstrate a thoroughly documented position with calibrated economic remedies, not to argue principle.

Most TSAs have a hard requirement that no party files formal proceedings until the executive escalation completes. The contract makes the escalation tiers a condition precedent to mediation, arbitration, or litigation. A premature filing can be dismissed for failure to follow the dispute procedure, which delays resolution and damages the operating relationship. The work pairs with the governance committee structure playbook.

Mediation, arbitration, and the formal track.

When the executive tier fails, the formal track activates. Most modern TSAs require non binding mediation before any binding proceeding. The mediator is a neutral third party with experience in commercial contracts. Mediation runs over one to three days and resolves a high percentage of TSA disputes. The buyer side team prepares a mediation brief that lays out the contractual basis, the operating impact, the financial demand, and the settlement range.

Arbitration is the binding step. Most TSAs name a specific arbitration body (the AAA, JAMS, the ICC, the LCIA, SIAC, or HKIAC), specify the rules, and define the seat. Arbitration runs 6 to 18 months on a typical TSA dispute, including discovery, expert reports, and hearings. The TSA cost during the arbitration period continues to accrue, which creates pressure on both parties to settle before the award.

Litigation appears in TSAs that did not choose arbitration. The choice between arbitration and litigation is a major drafting decision. Arbitration delivers confidentiality, faster resolution in many jurisdictions, and a panel that understands commercial contracts. Litigation delivers public precedent and broader discovery. The work pairs with the arbitration versus litigation playbook.

Settlement at any tier is usually documented in a settlement and release that ends the specific dispute without prejudicing other open or future matters. Drafting matters. A loose release can extinguish unrelated claims. A tight release preserves the buyer's position on every other open or potential dispute. The buyer side legal team writes the release language, not the seller.

The buyer side dispute playbook and the role of the advisor.

A buyer side dispute playbook makes disputes faster and cheaper. The playbook covers issue identification, evidence capture, escalation choreography, settlement ranges, and exit options. The buyer applies the playbook from Day One so that the dispute record is built in real time, not reconstructed after a notice goes out. The discipline reduces dispute duration and improves settlement outcomes.

Common buyer side dispute categories include overcharges on cost-plus services, mark-up calculation errors, undercharged services that the seller later true ups, SLA breaches with disputed service credit applications, scope drift charged outside the change control process, extension fee escalations applied without a defined trigger, and pass-through costs charged at marked up rates. Each category has a defined evidentiary playbook. The work pairs with the overcharge identification framework.

The advisor brings precedent. Across multiple TSAs, certain seller positions repeat. Certain settlement ranges recur. Certain arbitration panels and mediators tend to apply specific reasoning patterns. The advisor calibrates the buyer's strategy with that precedent, which beats either bluffing or capitulating without context.

TSA dispute resolution programs are delivered under a Fixed Fee or Portfolio Retainer engagement model through TSA dispute resolution with the dispute advisor sitting alongside the buyer's legal counsel. The work runs faster when the dispute discipline starts at Day One rather than after the first notice arrives.
