Contract Termination Lawyer | Grounds, Notice, and the Money That's Already Changed Hands
Contract termination disputes rarely turn on one dramatic fact — they turn on whether a valid ground for termination existed, whether the terminating party followed the correct notice procedure, and how restitution and damages are calculated once the contract ends (민법 제543조 내지 제551조). Get any one of these wrong and a termination that felt obviously justified can be found invalid, leaving the other side able to claim performance or damages instead. This page explains the legal grounds recognized under the Civil Code, the difference between statutory and contractual termination rights, and what typically happens to deposits, part-performance, and damages once a contract is unwound.
Contract Termination | Not Every 'Termination' Is the Same Thing
People often use the word 'terminate' loosely, but Korean civil law actually distinguishes several distinct mechanisms with different requirements and different consequences. Knowing which one applies to your situation changes what you need to prove and what you can recover.
| Legal basis | Civil Act default rules, no contract clause needed |
| Requirement | Breach + (usually) a demand for performance with a deadline |
| Effect | Contract void from the start; mutual restitution |
| Damages | Can be claimed alongside rescission |
Available when the other party fails to perform its obligation and, after being given a reasonable period to cure, still fails to perform (민법 제544조). For obligations where performance is impossible, no demand period is required (민법 제546조).
| Legal basis | The termination clause in the contract |
| Requirement | Trigger event defined in the clause (e.g., late payment, insolvency) |
| Effect | Follows whatever the clause provides |
| Damages | Governed by clause, but statutory rules can still apply |
Courts will still review whether the clause is unconscionable or violates the Act on the Regulation of Terms and Conditions if the contract is a standard-form agreement (약관의 규제에 관한 법률).
| Legal basis | Civil Act provisions on 해지 rather than 해제 |
| Requirement | Depends on contract type; often requires notice period |
| Effect | Ends the relationship going forward only, no retroactive undoing |
| Damages | Limited to loss from premature ending, not full restitution |
Korean law separates 해제 (rescission, retroactive) from 해지 (termination, prospective only) — this distinction matters most for leases and continuing service contracts (민법 제550조).
Contract Termination | When Can You Actually Terminate?
Before sending a termination notice — or challenging one you received — check which of these grounds actually applies to your facts. Each has its own procedural requirements, and using the wrong ground can make an otherwise valid termination ineffective.
The other party was supposed to perform by a certain time and didn't. You generally must first demand performance within a reasonable additional period, and only if that period passes without performance can you rescind. The demand itself is a common point of dispute — courts look closely at whether it clearly stated a deadline.
Performance has become objectively impossible — the specific goods were destroyed, or a specific piece of real estate was sold to someone else. No demand period is required here because giving more time would be pointless; you can rescind immediately once impossibility is established.
Once a contract is rescinded, each party must return what it received, and if money is involved, statutory interest may be added from the date of receipt (민법 제548조). Rescission does not bar a separate damages claim for losses caused by the breach (민법 제551조) — these are two distinct claims often pursued together.
Where a contract has been partly performed, courts examine whether the breached portion was significant enough to justify unwinding the whole contract, or whether the appropriate remedy is a reduction in price or partial damages instead. This is a frequent point of contention in construction and supply contracts.
The right to rescind belongs to the party who did not breach. It is exercised by a unilateral declaration to the other party and, once made, generally cannot be withdrawn (민법 제543조). Continuing to accept partial performance after learning of a breach can sometimes be treated as a waiver of the right to rescind, so timing matters.
Watch for waiver by conduct
If you keep accepting deliveries, payments, or partial performance after you already know about a breach, a court may find you implicitly waived your right to terminate on that ground. If you intend to preserve the option to terminate, it helps to state that reservation in writing when you accept anything further.
Contract Termination | Notice Requirements and Common Drafting Mistakes
A termination notice that skips a required step can be challenged and set aside, regardless of how clearly the other side breached the contract. These are the points that come up most often in disputes over whether a notice was valid.
Did you give a proper demand period first?
For delay-based rescission, you typically need to notify the other party of the specific obligation owed and give a reasonable additional period to perform before you can rescind (민법 제544조). A notice that simply says 'the contract is terminated' without ever having given that opportunity to cure is vulnerable to challenge. What counts as 'reasonable' depends on the nature of the obligation — a few days for a simple payment, longer for something requiring preparation.
Does the contract have its own notice clause that overrides the default rule?
Many commercial contracts specify their own notice method (written notice to a designated address, a set cure period, specific triggering events). If the contract has such a clause, it generally governs over the Civil Act default, so the first step in any dispute is checking whether the contract itself already answers the notice question before applying general law.
When does the termination actually take effect?
A rescission declaration takes effect when it reaches the other party, not when you send it — this matters if the other party disputes receipt or claims they cured the breach before the notice arrived. Keeping proof of delivery (certified mail, content-certified mail) is standard practice specifically because effective date is so often contested.
Contract Termination | Restitution: Getting Back What You Paid
Once a contract is rescinded, both sides owe each other restitution — but working out exactly what that means in money terms is where a lot of the actual dispute happens.
Money paid must be returned with interest
If you paid a deposit or installment before rescission, the other party must return it, and statutory interest is added from the date they received it, not from the date of rescission (민법 제548조 제2항). This can matter significantly if a long time passed between payment and termination.
What if the goods or work can't simply be handed back?
Where partial performance has already been consumed or incorporated (e.g., construction work built into a structure, services already rendered), restitution in kind is often impossible and the dispute shifts to valuing that partial performance in money — this is one of the more technical and fact-heavy areas of a termination case.
Restitution and damages are separate claims
Recovering your deposit through restitution does not use up your right to claim damages for losses the breach caused beyond that — lost profit, cost of a substitute transaction, and similar losses can be claimed in addition (민법 제551조). The two claims are calculated differently and should be pleaded separately.
Contract Termination | Liquidated Damages and Penalty Clauses
Most Korean commercial contracts include a clause specifying damages or a penalty in the event of termination. These clauses are enforceable, but not automatically — courts retain a power to intervene.
Courts can reduce an excessive penalty clause
If a contractually agreed penalty or liquidated damages amount is found to be unreasonably excessive, a court may reduce it to a reasonable amount (민법 제398조 제2항). This is a frequently litigated issue in real estate and construction termination disputes where the contract sets a penalty as a percentage of contract price.
Deposits framed as 'earnest money' can be treated as a penalty by default
Unless the contract states otherwise, earnest money paid on a real estate sale is presumed to function as liquidated damages if the buyer defaults — meaning the seller may keep it, or the seller may have to pay back double if the seller is the one in breach, depending on how the clause and practice are structured. This default presumption is one of the most commonly misunderstood points in real estate termination disputes.
Contract Termination | From Notice to Resolution
We review the contract, the facts of the alleged breach, and any notices already sent or received to identify which termination ground and procedure actually apply.
If you haven't yet sent a termination notice, we help draft one that meets the statutory and contractual requirements. If you received one, we assess whether it was validly issued and prepare a response.
Many termination disputes settle at this stage once both sides understand the restitution and damages exposure — a negotiated settlement can save the time and cost of litigation.
If negotiation fails, we file or defend a civil claim for confirmation of termination, restitution, and/or damages, and represent you through document exchange, hearings, and judgment.
If a judgment is obtained but not voluntarily complied with, we assist with compulsory enforcement against the other party's assets.
Contract Termination | How Fees Are Typically Calculated
An initial review of your contract and the facts is usually charged as a flat consultation fee, which can often be credited toward the retainer if you proceed with representation.
The upfront retainer is generally set based on the value in dispute (the amount you are trying to recover or the amount claimed against you) and the complexity of the contract and evidence involved.
If a success fee applies, it is usually calculated as a percentage of the amount actually recovered or the amount successfully defended against, and is only payable upon a favorable outcome.
Court filing fees, stamp duties, and delivery costs (e.g., content-certified mail for notices) are separate from attorney fees and are generally billed as incurred.
If enforcement against assets becomes necessary after judgment, additional fees and costs apply for that separate stage.

Contract Termination | Self-Check Before You Act
1️⃣ Before Sending a Termination Notice
- Have you clearly identified which specific obligation the other party failed to perform?
- Did you send a written demand giving a reasonable period to cure, before declaring termination?
- Does your contract have its own termination clause that should govern instead of the default rule?
- Have you kept evidence of delivery for any notice you plan to send?
2️⃣ If You Received a Termination Notice
- Did the notice actually give you a chance to cure before declaring termination?
- Was the notice delivered to the correct address and can the sender prove receipt?
- Do you believe you had already performed, or were prevented from performing by the other side?
- Is there a restitution or damages amount being demanded that you dispute?
3️⃣ Working Out What Happens to Money Already Paid
- Has any deposit, installment, or advance payment been identified for restitution?
- Is there a liquidated damages or penalty clause, and does the amount seem disproportionate?
- Has partial performance already occurred that can't simply be returned in kind?
- Are you also claiming (or facing) a separate damages claim beyond restitution?
4️⃣ If the Contract Is a Continuing Relationship (Lease, Service)
- Are you dealing with 해지 (prospective termination) rather than 해제 (retroactive rescission)?
- Does the contract or relevant statute require a minimum notice period before ending it?
- Have you calculated damages only for the period of premature termination, not the whole contract?
