A settlement agreement is a legally binding contract that ends a dispute without a trial: one side pays money or performs some obligation, and in exchange the other side gives up its legal claims. These contracts appear everywhere in civil litigation — personal injury, employment, commercial disputes — because they let the parties control the outcome instead of handing it to a judge or jury. What you sign governs how much you receive, what you waive forever, what you owe in taxes, and whether you can go back to court if the deal falls apart.
What the Agreement Must Contain
Every agreement identifies the parties. The side giving up claims is the releasor; the side being released is the releasee. Names, addresses, and entity designations have to be exact. A misspelled corporate name or the wrong LLC suffix can create problems when it’s time to enforce the agreement or process payment.
Most agreements open with “recitals,” a plain-narrative section describing what happened, when, and why the parties are settling. If a court later needs to interpret the contract, the recitals tell the judge what the parties were trying to accomplish.
The payment section is where precision matters most. The agreement should state the exact dollar amount, whether it’s paid in a lump sum or installments, the due dates, the method of transfer, and what happens if a payment is late, including any interest that accrues. Vague payment language is where most post-settlement disputes start.
The Release of Claims
The release clause is the core of the agreement. It defines which claims the releasor is giving up. A general release covers all claims between the parties up to the signing date, known or unknown. A specific release is narrower, waiving only claims tied to a particular event, such as one accident or one contract.
The difference matters. Under a general release, if you discover six months later that an accident also caused a disc injury you didn’t know about, you can’t go back for more. That finality is exactly what the paying side wants and exactly what the receiving side has to weigh before signing.
To make a general release stick for unknown claims, attorneys routinely add language modeled on a well-known California statute. The default rule in many jurisdictions is that a general release does not reach claims the releasor doesn’t know about at signing. Overriding that default requires explicit language where the releasor acknowledges waiving unknown claims and accepts the risk that undiscovered harm won’t be compensable later. Without that specific waiver, a court may let the releasor reopen the case based on later-discovered injury.
Confidentiality and Non-Disparagement
Most settlement agreements include a confidentiality clause that bars both sides from disclosing the terms, with standard carve-outs for tax preparation, court orders, regulatory inquiries, subpoenas, and enforcement of the agreement itself. Breaching confidentiality can trigger a separate damages claim, and many agreements include a liquidated damages clause setting a pre-agreed penalty so the non-breaching party doesn’t have to prove the exact harm a leak caused.
Non-disparagement clauses go further, restricting what the parties can say about each other publicly. They exist to prevent one side from technically keeping the amount secret while attacking the other party’s reputation.
Federal law now limits how far these provisions can reach. The Speak Out Act, signed in December 2022, makes pre-dispute nondisclosure and non-disparagement provisions unenforceable when the underlying claim involves sexual assault or harassment. Timing is the key: clauses signed before a dispute arises, such as those in an employment onboarding packet, are unenforceable, but confidentiality terms negotiated as part of a settlement after allegations have been made can still bind the parties. Under federal tax law, a business cannot deduct any settlement payment related to sexual harassment or abuse if the payment is subject to a nondisclosure agreement, and the same rule applies to associated attorney’s fees.1Internal Revenue Service.

What Makes the Agreement Legally Valid
A settlement agreement is a contract and must satisfy the same elements as any other enforceable contract. The first is consideration: each side has to exchange something of value. The plaintiff gives up the right to sue; the defendant provides compensation. Without that mutual exchange, a court may treat the document as an unenforceable promise.
Both sides also have to genuinely agree on the terms. This is called mutual assent, and ambiguous language can undermine it. If one party can later show they reasonably read a key term differently than the other side intended, the agreement becomes vulnerable to challenge.
Every signer must have the legal capacity to sign, which generally means being of legal age and of sound mind. A settlement signed by someone with severe cognitive impairment, or by a minor without proper court approval, may be void or voidable.2Office of the Law Revision Counsel. 29 U.S. Code 626 – Recordkeeping, Investigation, and Enforcement Consent must also be voluntary. Courts will set aside an agreement if a party was coerced through threats, fraud, or duress.
Extra Rules for Age Discrimination Settlements
When a settlement waives claims under the federal Age Discrimination in Employment Act, the law adds requirements that protect workers over 40. The waiver must be written in plain language the employee can understand, must specifically reference ADEA rights, and must advise the employee in writing to consult an attorney before signing.2Office of the Law Revision Counsel. 29 U.S. Code 626 – Recordkeeping, Investigation, and Enforcement
Timing is strict. An individual employee must receive at least 21 days to consider the agreement before signing. If the waiver is part of a group layoff or exit incentive program, that window extends to at least 45 days. After signing, the employee has a 7-day revocation period and can back out entirely during that time. The agreement cannot take effect until the revocation window closes, and the parties cannot agree to shorten it.2Office of the Law Revision Counsel. 29 U.S. Code 626 – Recordkeeping, Investigation, and Enforcement When the waiver resolves a charge already filed with the EEOC or a pending lawsuit, the rigid 21-day rule relaxes to a “reasonable period,” though offering the full 21 or 45 days remains the safest practice.3eCFR. Part 1625 – Age Discrimination in Employment Act
Skipping any of these steps isn’t just a technicality. An ADEA waiver that fails these requirements is not “knowing and voluntary” under federal law and is unenforceable. The employer loses the protection it paid for.
How Settlement Money Is Taxed
How a settlement is taxed depends on what the underlying claim was about. Failing to address tax treatment in the agreement itself creates expensive problems for both sides.
Damages received for personal physical injuries or physical sickness are excluded from gross income under federal tax law, including the portion that compensates for lost wages caused by the physical injury.4Office of the Law Revision Counsel. 26 U.S. Code 104 – Compensation for Injuries or Sickness Punitive damages are always taxable, even in physical injury cases, with a narrow exception for wrongful death claims in states where punitive damages are the only available remedy.5Internal Revenue Service. Tax Implications of Settlements and Judgments
Most everything else is taxable. Settlements for emotional distress without an underlying physical injury, defamation, discrimination, and contract disputes are all included in gross income. Emotional distress damages get a small carve-out: you can exclude the portion that reimburses medical care you actually paid for to treat the emotional distress.4Office of the Law Revision Counsel. 26 U.S. Code 104 – Compensation for Injuries or Sickness
Employment settlements deserve extra care. Back pay in a discrimination case, severance, and other payments tied to lost employment are treated as wages subject to income tax withholding and to Social Security and Medicare taxes. Emotional distress damages in an employment case are taxable as income but are not subject to employment taxes.5Internal Revenue Service. Tax Implications of Settlements and Judgments
The agreement should explicitly allocate the total among categories of damages. If it’s silent, the IRS looks to the payor’s intent to determine how to characterize the payment. For taxable settlements of $600 or more, the paying party must issue a Form 1099-MISC to the recipient.6Internal Revenue Service. General Instructions for Certain Information Returns When attorney’s fees are part of a taxable settlement, the payor must file separate information returns listing both the attorney and the plaintiff as payees.5Internal Revenue Service. Tax Implications of Settlements and Judgments
Medicare’s Claim in Injury Settlements
If the settlement involves a personal injury claim and the injured party is a Medicare beneficiary, federal law requires that Medicare’s financial interest be addressed before money changes hands. Under the Medicare Secondary Payer rules, if Medicare has paid for treatment related to the injury being settled, it has a right to be reimbursed from the proceeds.7Office of the Law Revision Counsel. 42 USC 1395y – Exclusions From Coverage and Medicare as Secondary Payer
The beneficiary or their attorney reports the claim to Medicare through the Medicare Secondary Payer Recovery Portal or by contacting the Benefits Coordination and Recovery Center, providing the Medicare number, date of injury, description of the harm, and the insurer’s name and address.8Centers for Medicare and Medicaid Services. Reporting a Case
If reimbursement isn’t made within 60 days of receiving notice of Medicare’s claim, the government begins charging interest. Medicare’s lien takes priority, and parties who fail to satisfy it face recovery actions. The agreement itself should spell out how and when Medicare will be paid.
Signing, Filing, and Keeping the Court Involved
Signing often involves a notary who verifies identity and confirms the signatures are genuine, which protects against later claims of forgery or unauthorized signing. Electronic signatures are valid for settlement agreements under the federal E-SIGN Act, which provides that a contract or signature cannot be denied legal effect solely because it is in electronic form.9Office of the Law Revision Counsel. 15 U.S. Code 7001 – General Rule of Validity
When a lawsuit is already pending, the signed agreement is filed with the court through a stipulation of dismissal, signed by all parties who have appeared in the case and asking the court to end the litigation.10LII / Legal Information Institute. Federal Rules of Civil Procedure Rule 41 – Dismissal of Actions Filing the stipulation formally closes the case.
Make Sure the Court Keeps Its Enforcement Power
Once a case is dismissed, the court generally loses the power to enforce the settlement. The U.S. Supreme Court made this clear in Kokkonen v. Guardian Life Insurance Co., holding that a federal court lacks jurisdiction to enforce a settlement agreement after dismissal unless the dismissal order specifically retains that authority.11Justia. Kokkonen v. Guardian Life Insurance Company of America, 511 U.S. 375
The practical fix is simple. The stipulation of dismissal should state that the court retains jurisdiction to enforce the settlement, or the terms of the agreement should be incorporated into the court’s order. Without one of those, a party whose opponent fails to pay has to file an entirely new breach-of-contract lawsuit rather than return to the original judge.
What to Do If the Other Side Doesn’t Follow Through
A signed settlement is a contract, and breaking it exposes the breaching party to the same remedies as any other contract breach. The non-breaching party generally has three paths.
The first is a motion to enforce in the original court. If the dismissal order retained jurisdiction, the non-breaching party can file a motion asking the original judge to compel compliance. This is the fastest and least expensive route. The motion should include supporting evidence such as the signed agreement and an affidavit describing the breach, and the court will hold a hearing that functions like a mini-trial on the contract claim.
The second is a separate lawsuit for breach of contract. If the original court didn’t retain jurisdiction, the non-breaching party has to file a new complaint alleging breach of the settlement and seeking either specific performance (forcing the other side to do what they promised) or money damages.
The third is a liquidated damages provision in the agreement itself. Many settlements include a pre-set penalty for certain breaches, particularly confidentiality violations. These clauses are enforceable when the pre-set amount is a reasonable estimate of the harm a breach would cause and the actual harm would be difficult to calculate after the fact.
If the original case was dismissed and needs to be reopened for an enforcement motion, the moving party may first have to ask the court to vacate the dismissal and reinstate the case. Some attorneys combine the motion to reinstate with the motion to enforce. Either way, bringing witnesses and documentary evidence to the hearing is essential, because the judge is effectively deciding a contract dispute on the spot.
The agreement can also provide that the non-breaching party recovers attorney’s fees in enforcement proceedings. Including that provision creates a real deterrent, since the breaching party knows they’ll pay what they owe and the cost of being forced to pay it.
