On an Omani file the document type decides everything. A civil extract, a diploma, a criminal record extract or a notarised power of attorney travels with an apostille; a company’s customs or trade document does not, because of a declaration Oman made in 2021, and goes through the consular route instead. This page is for the Omani ministry, employer or partner company receiving Turkish papers and for the Turkish office receiving Omani ones: what the declaration of 23 March 2021 says, the route for commercial papers, the undated authority record in Muscat, the uncontested accession of 2012, and the spelling “Oman (Umman)” on the Turkish list.
What Oman declared on 23 March 2021
By its declaration of 23 March 2021 Oman stated that it applies the Convention only to the civil public documents listed in article 1(a) to (d): court documents, administrative documents, notarial acts and official certificates placed on private documents. The same declaration excludes commercial and customs documents and diplomatic and consular documents. The Convention itself already keeps diplomatic and consular documents and administrative documents dealing directly with commercial or customs operations outside its scope in the last paragraph of article 1; Oman’s declaration writes that boundary out expressly for its own practice. The declaration has no objection effect on the relationship between Türkiye and Oman; its effect is on the type of document.
Customs and trade papers for Muscat: the route that replaces the apostille
A Turkish company that has to send a customs document or an administrative paper dealing directly with a trade operation to its Omani partner gains nothing from an apostille at the district governor’s office: the declaration keeps such papers outside the Convention, so the certificate is not expected to be read as a Convention certificate in Oman. What remains is the route that the Legalisation Unit of the Turkish Ministry of Foreign Affairs describes for a document that will not be apostilled: the translation is certified by a notary, the document is certified at the governor’s office of the place of issue, then at the Legalisation Unit, and finally at the Omani mission. This place rule comes from the undated information sheet of the Turkish Ministry of Foreign Affairs; whether the 2024 amendment of article 199 of the Notaries Law also covers this certification was not verified in this site’s survey. The same company’s signature circular and power of attorney, being notarial acts, travel with an apostille. Oman’s declaration makes the two routes visible on a single file, so the papers are sorted one by one before anything is sent. The procedure of the Omani mission was not surveyed on this site.
The Consular Department in Muscat: an undated authority record
According to the HCCH authority page, the authority in Oman lies with the Consular Department of the Ministry of Foreign Affairs, with an address in Muscat. The page carries no update date and no fee information, and the data record behind this page marks both gaps as unverified. An undated record means nobody knows when the page was written; if the name or the address of the authority has changed, the change may not have reached the HCCH. The e-APP chart of 13 August 2026 has no Oman row either: no electronic certificate and no online register have been reported.
12 May 2011 to 30 January 2012: an accession nobody contested
Oman deposited its instrument of accession on 12 May 2011, and the HCCH status table shows 30 January 2012. Within the six-month objection window no state objected; Türkiye did not either, and the full status report records no exception between the two. Oman is absent from the HCCH list of Members, one of the states that joined the Convention without joining the organisation. Oman has not acceded to ETS 063, CIEC 16 or CIEC 17, so no multilingual form exemption exists for civil records.
An Omani certificate in a Turkish office, with no register to check
An employment contract, a marriage record or a power of attorney drawn up in Oman reaches Türkiye with the certificate of the Consular Department; the Turkish Ministry of Foreign Affairs does not legalise a document that already carries an apostille. No online verification page is known for Omani certificates. Oman’s declaration works in the other direction too: a customs document or a trade-related administrative paper from Oman carries no apostille and arrives legalised by one of the two methods in the Turkish Ministry’s sheet, at the Turkish mission in Oman or at the Omani mission in Türkiye. The Turkish office sets the form of the Turkish translation it accepts and says for itself whether the Consular Department’s certificate is to be translated too.
“Oman (Umman)” on the Turkish list, Arabic translation and two open points
According to this site’s data record, the Turkish official list writes the country as “Oman (Umman)”, so anyone searching official Turkish lists tries both spellings. Whether Omani institutions accept English alongside Arabic was not verified in this site’s survey. A translation made in Türkiye is notarised, and the notarial act receives its own apostille from the valilik or kaymakamlık, the provincial or district governor’s office; the certificate attests the notary’s signature, not the text. The original of a court judgment is apostilled by the adli yargı adalet komisyonu başkanlığı, the judicial commission at a high criminal court seat. For the six document types handled by e-Apostil, the official Turkish electronic apostille system, an electronic certificate exists, but no Omani electronic certificate has been notified and acceptance is asked in advance. The two open points come straight from the data record: the date and the fee of the authority page. A translation office renders the text; it gives no legal opinion on whether a paper falls inside the declared scope.
