1. The question
An apostille or a notarized document is obtained, then used months later. Is it still valid?
There is no single answer, because validity is determined by the receiving authority rather than by the Convention or by the issuing office.
2. The apostille itself
The Convention does not set an expiry for an apostille.
An apostille certifies that a signature or seal on a document was authentic at the time it was issued. That fact does not change with time.
So the apostille does not expire. What expires, or becomes unacceptable, is the underlying document or the receiving authority’s tolerance for its age.
3. Document age limits
Receiving authorities commonly impose age limits on the underlying document.
Common examples.
Criminal record certificates: frequently three to six months from issue.
Medical certificates: typically three months.
Certificates of no impediment and similar marital status documents: typically three to six months.
Financial statements: typically one year, tied to the accounting period.
Company documents: variable, but a business licence more than a year old may be questioned.
Academic certificates: generally no age limit.
These limits come from the receiving authority, and they are not uniform.
4. The notarization and the underlying document
A notarized copy of a document is a notarial act. The notary certifies the copy against the original at the time of certification.
If the underlying document changes after notarization, the notarial certificate no longer describes the current document.
A notarized copy of a business licence whose registered capital was subsequently increased, and which was reissued, describes an outdated document.
5. The practical consequence
Two separate clocks.
The apostille does not expire.
The receiving authority’s tolerance for the age of the document does.
Where a document sits on a shelf for a year and is then used, the apostille is valid and the receiving authority may refuse the document as too old.
6. When this bites
The pattern: an exporter prepares a full document set for one destination or one transaction, and later needs the same documents for a different purpose.
The documents exist and the apostilles are on them. The exporter uses them.
The receiving authority rejects them as too old, or rejects them because the underlying document has been superseded.
7. What to do
For each document type used regularly, record the receiving authority’s age requirement.
For documents with short validity, such as criminal record and medical certificates, obtain them when needed rather than in advance.
For documents with long validity, such as academic certificates, an apostille obtained years ago remains usable.
Re-notarize after any change to the underlying document.
8. The cost calculation
Obtaining documents and apostilles in advance is sometimes sensible, for example when a tender requires a document set within a short window.
But advance preparation only works for document types without a short age limit.
For the types with short limits, advance preparation guarantees that the documents will be too old by the time they are needed.
9. Common errors
Assuming the apostille expires
It does not. The document does.
Using a criminal record certificate from last year
Short validity period.
Using a notarized copy of a superseded document
The notarial certificate describes an old version.
Preparing documents far in advance for a tender
Works for academic certificates, fails for criminal records.
Not recording the receiving authority’s age requirement
The requirement is the operative limit, and it is not in the Convention text.
10. Closing view
The validity question has a clean answer and a messy one.
The apostille does not expire. The document might, in the eyes of the receiving authority, and that authority’s view is what governs.
