The lease has been signed, and everything seems fine at the beginning.
But the real problems usually arise at the end.
When the lease term expires—
the tenant refuses to move out, rent is unpaid, or the security deposit is withheld—
and all that comes back is:
“Then go ahead and sue.”
That’s when it becomes clear:
the biggest cost is not the deposit itself,
but the time, money, and energy that follow.
In reality, there is something that can be done from the very beginning
to significantly reduce these risks—
lease notarization.
What Does the Law Say?
Compulsory Enforcement Act, Article 4, Paragraph 1, Subparagraph 4 :
“Notarized documents which may serve as a basis for compulsory enforcement pursuant to the Notary Act.”
✨ Plain Explanation: A qualified notarized document can serve the same function as a final court judgment.
This means enforcement can proceed directly—without going through a full lawsuit.

Notary Act, Article 13, Paragraph 1, Subparagraphs 1 and 3 :
“A notarized instrument prepared by a notary at the request of the parties, specifying that it may serve as a basis for compulsory enforcement, may be enforced pursuant thereto in the following cases:
1. Where the subject matter is the delivery of a specified sum of money, substitute goods, or negotiable securities.
3. Where a lease or loan for use of a building or other structure provides for a fixed term and requires return upon expiration.”
✨ Plain Explanation: If the lease clearly states “subject to compulsory enforcement,” then things like unpaid rent, deposit refunds, or returning the property at the end of the lease can be enforced directly using the notarized document.

Notary Act, Article 13, Paragraph 2 :
“The notarized instrument referred to in the preceding paragraph shall also be effective against successors of the parties and persons who possess the subject matter on behalf of the parties or their successors after the instrument is made.”
✨ Plain Explanation: Even if ownership of the property changes later,
the notarized lease usually remains valid and enforceable.

Notary Act, Article 70 :
“A notary shall not prepare a notarized instrument for matters that violate laws or regulations or for invalid legal acts.”
✨ Plain Explanation: Illegal or invalid clauses cannot be “fixed” by notarization.
Notarization is not a magic shield.

Notary Act, Article 72 :
“If the notary has doubts as to whether the content of the requested notarization complies with laws or reflects the true intent of the applicant, the notary shall explain such doubts. If the applicant still insists, the notary shall prepare the instrument as requested, but shall record such explanation and the applicant’s statement therein. ”
✨ Plain Explanation: The notary will warn about risks,
but ultimately will not decide for the parties.
If the parties insist, notarization can still proceed—with notes recorded.

Why Do People Say Notarization Can Save You a Lawsuit?
The most practical reason: cost difference.
Assume the security deposit is NT$40,000.
Hiring a lawyer for a first-instance lawsuit may cost NT$70,000–80,000.
If the case is appealed, the total cost may exceed NT$150,000.
What does that mean?
Even if the case is won,
it may not be financially worthwhile.
But if the lease was notarized in advance,
and includes a clause allowing compulsory enforcement,
the situation is completely different.
👉 What can be done directly:
- Take the notarized document → file with the enforcement court
- Apply for compulsory enforcement
- No need to go through a full lawsuit
This is the real value of notarization.
Common Situations Where Notarization Makes a Big Difference
1️⃣ Security Deposit Not Returned
The tenant has moved out and the property is in good condition,
but the landlord refuses to return the deposit.
👉 With notarization: Direct enforcement
👉 Without notarization: Must file a lawsuit
2️⃣ Tenant Refuses to Move Out After Lease Expiry
The lease term has ended, but the tenant continues to occupy the property.
👉 With notarization (and a return clause): Direct eviction enforcement
👉 Without notarization: Must first obtain a court judgment
3️⃣ Long-Term Rent Arrears
The tenant fails to pay rent or disappears.
👉 With notarization: Direct monetary enforcement (usually requires proof of demand notice)
👉 Without notarization: Lawsuit required to confirm the claim
Notarization Is Powerful—But Not Unlimited
Many people assume notarization allows direct enforcement in all cases.
That is not entirely true.
Important limitations include:
- Only applies clearly to return upon lease expiration
Early termination disputes usually still require court review - Enforcement courts conduct formal review only
Substantive disputes may block enforcement - Rent arrears often require proof of demand (e.g., certified letter)
- Subtenants are generally not directly enforceable
- Lease renewal requires re-notarization
What Does Lease Notarization Actually Protect?
Notarization is not just about making a contract “more formal.”
Its real purpose is:
to deal with future risks in advance.
Instead of reacting after disputes arise,
it sets up a clear exit mechanism from the beginning.
It is also important to understand:
notarization does not only protect one side.
- Tenants gain protection for deposit refunds
- Landlords gain protection for rent collection and property return
Ultimately, it ensures that both parties’ rights are easier to enforce.

Conclusion
The real value of lease notarization does not lie at the beginning,
but at the moment when problems arise.
When disputes occur, the difference between having notarization and not is often the difference between direct enforcement and starting a lawsuit from scratch.
For relatively small disputes, this difference can matter more than winning or losing.
Of course, notarization is not a cure-all and has its limits.
But when properly structured, it can significantly reduce uncertainty and future costs.
For those seeking a more stable and predictable rental relationship, notarization is not unnecessary—it is often the step that avoids many unnecessary troubles later.
