Since 2018
For over 8 years, we've helped clients navigate Polish law, combining our solid legal knowledge with practical immigration experience.
Apostille Services for Documents
ONE PLUS helps individuals, entrepreneurs, international students, and companies obtain an apostille for documents issued in Poland and Ukraine. We assist clients who need to use official documents abroad for immigration procedures, residence permits, citizenship applications, employment, university admissions, business registration, marriage registration, professional licensing, and other legal or administrative matters.
The apostille procedure depends primarily on the country where the document was issued. Documents issued in Poland follow a different legalization process than documents issued in Ukraine. In addition, certain categories of documents require separate verification procedures before an apostille can be issued. Our specialists review each case individually, determine the correct legalization path, and help clients avoid common mistakes that often lead to delays or rejected applications.
For more than 11 years, ONE PLUS has been supporting foreigners and businesses with document legalization, residence permits, citizenship applications, sworn translations, and administrative procedures throughout Poland. Thanks to our experience working with government authorities, universities, courts, and public institutions, we can quickly identify the most efficient way to legalize a document for use abroad.
What Is an Apostille?
An apostille is an internationally recognized certification that confirms the authenticity of a public document, the signature of the issuing official, and the official seal of the authority that issued the document.
Once an apostille has been attached, the document can generally be used in countries that are parties to the Hague Apostille Convention without the need for additional consular legalization.
In practice, apostilles are commonly required for use in European Union countries, the United Kingdom, Canada, the United States, Australia, New Zealand, and many other jurisdictions around the world.
When Is an Apostille Required?
Foreign nationals most frequently require an apostille when dealing with:
- citizenship applications;
- residence permit and immigration procedures;
- employment abroad;
- university admissions;
- diploma recognition;
- professional licensing;
- marriage registration;
- inheritance matters;
- business registration;
- court proceedings;
- notarial procedures;
- opening bank accounts abroad;
- visa and immigration applications.
The exact requirements depend on the country and institution requesting the document. In many situations, an apostille is mandatory before the document can be accepted by foreign authorities.
Documents Most Commonly Apostilled
The most frequently legalized documents include:
- birth certificates;
- marriage certificates;
- divorce certificates;
- death certificates;
- criminal record certificates;
- university diplomas;
- school certificates;
- diploma supplements;
- academic transcripts;
- powers of attorney;
- court judgments;
- company registration documents;
- corporate records;
- medical certificates;
- immigration and citizenship documents.
Before beginning the procedure, we verify whether the document qualifies for apostille and whether any preliminary certification is required.
Apostille for Diplomas and Educational Documents
Educational documents deserve special attention because their legalization process often differs from standard civil documents.
Many foreigners complete their studies in Poland and later relocate to countries such as Canada, the United States, the United Kingdom, Germany, the Netherlands, Australia, or other destinations. In these situations, Polish diplomas, degree certificates, academic transcripts, and educational records frequently require additional verification before an apostille can be issued.
Contrary to popular belief, educational documents are not always legalized through the same authority that handles civil documents. Depending on the document type and issuing institution, additional confirmation from educational authorities may be required.
ONE PLUS assists with apostilles for:
- university diplomas;
- high school certificates;
- diploma supplements;
- academic transcripts;
- qualification certificates;
- professional certificates;
- educational records and academic documents.
Before starting the procedure, we verify the document and determine the correct legalization route. This helps avoid unnecessary delays and ensures that the document will be accepted by the institution abroad.
Apostille for Criminal Record Certificates (KRK)
One of the most requested services among foreigners is obtaining a Polish Criminal Record Certificate (KRK) together with an apostille.
This document is often required when applying for citizenship, immigration programs, residence permits, professional licenses, work permits, visas, or employment opportunities abroad.
Many countries require a criminal background check issued recently and properly legalized before it can be submitted as part of an immigration or licensing application.

Apostille for Documents Issued in Poland
Obtaining an apostille for Polish documents is one of the most common legalization procedures requested by foreigners living in Poland.
Many of our clients require apostilled documents when applying for immigration programs abroad, obtaining foreign citizenship, enrolling in universities overseas, accepting employment opportunities in another country, or completing international legal and business transactions.
While criminal record certificates remain the most popular document for apostille, we also regularly assist with birth certificates, marriage certificates, court decisions, powers of attorney, notarial documents, company registration documents, and educational records.
Educational documents are particularly common among foreigners who graduated from Polish universities and later decide to continue their careers abroad. Countries such as Canada, the United States, the United Kingdom, Australia, Germany, and the Netherlands often require legalized educational documents before recognizing foreign qualifications.
Before submission, our team carefully verifies whether the document is eligible for apostille, whether any additional certifications are required, and whether a sworn translation should be prepared for the receiving authority. This helps clients avoid delays and ensures that documents can be used immediately after legalization.
Apostille Fees in Poland
The cost of obtaining an apostille in Poland depends on the type of document, the issuing authority, processing time, and whether additional services such as sworn translation, document retrieval, certification, or legalization are required.
Apostille for Polish Documents
We regularly assist clients with apostilles for Polish criminal record certificates (KRK), university diplomas, academic transcripts, birth certificates, marriage certificates, powers of attorney, court decisions, and corporate documents intended for use abroad.
Apostille services in Poland start from 300 PLN net.
Before starting the procedure, our specialists carefully review the document and determine the correct legalization path. In some cases, additional verification by educational institutions, government authorities, or professional organizations may be required before an apostille can be issued.
Because every document follows a different procedure, we provide an individual assessment before work begins. Clients receive a clear quotation, estimated processing times, and a detailed explanation of the legalization process, ensuring complete transparency and helping avoid unexpected delays or additional costs.
Apostille for Ukrainian Documents
ONE PLUS also assists with apostilles for documents issued by Ukrainian authorities.
Depending on the document category, the apostille may be issued through:
- the Ministry of Justice of Ukraine;
- the Ministry of Education and Science of Ukraine;
- the Ministry of Foreign Affairs of Ukraine;
- other authorized institutions.
Before submission, we review the document and determine which authority is responsible for issuing the apostille.
Standard Processing

Express Processing

Apostille and Sworn Translation Services
In many cases, obtaining an apostille is only one part of the legalization process.
Foreign authorities frequently require a sworn translation prepared by a certified translator. Without a properly certified translation, even a correctly apostilled document may not be accepted by the receiving institution.
ONE PLUS cooperates with sworn translators throughout Poland and provides certified translations into English, Polish, German, Spanish, French, Ukrainian, Russian, and many other languages.
As a result, clients receive a complete package ready for submission to immigration authorities, universities, courts, banks, employers, professional associations, and government institutions.
Duplicates, Apostilles, and Document Legalization
Some documents cannot be apostilled immediately because they have been lost, damaged, or issued many years ago. In such situations, obtaining an official duplicate may be necessary before legalization can begin.
ONE PLUS also assists with obtaining replacement documents issued in Poland and Ukraine. If you require a duplicate certificate, diploma, civil status document, or another official record, we recommend visiting our dedicated page where you can find detailed information about processing times, requirements, and fees.
Why Clients Choose ONE PLUS
For more than 11 years, ONE PLUS has been helping foreigners, international students, entrepreneurs, employees, and companies navigate document legalization procedures in Poland.
Our clients come from the United States, Canada, the United Kingdom, Germany, Spain, Italy, Ukraine, Kazakhstan, and many other countries. Every case is different. A university graduate legalizing a diploma for employment abroad has different needs than a business owner preparing company documents for international expansion or a family applying for immigration status in another country.
What distinguishes our approach is that we do not simply submit documents. Before starting the procedure, we analyze the purpose of legalization, verify the destination country, review document requirements, and identify potential issues that could delay the process.
Clients also appreciate that we provide several related services under one roof. If a document requires an apostille, sworn translation, duplicate issuance, certification, or additional legalization, we coordinate the entire process. This eliminates the need to communicate with multiple institutions separately and significantly reduces administrative complexity.
Over the years, we have developed extensive practical experience working with Polish public authorities, universities, courts, notaries, and administrative institutions. This allows us to guide clients efficiently while ensuring compliance with current legal requirements.
Apostille Assistance Across Poland
Obtaining an apostille may appear straightforward, but in practice the procedure often varies depending on the type of document, the issuing authority, and the country where the document will be used.
Educational documents, criminal record certificates, court judgments, company records, civil status documents, and notarial acts frequently follow different procedures and may require additional verification before legalization.
For this reason, many foreigners choose professional assistance rather than contacting multiple institutions independently. Our role extends beyond submitting paperwork. We verify the documents, determine the correct legalization route, explain every step of the process, and oversee the procedure until completion.
Whether you need an apostille for a Polish criminal record certificate, university diploma, birth certificate, marriage certificate, power of attorney, company document, or another official record, our team will guide you through the process from the initial consultation to the final legalized document ready for international use.
Our office is located in Wrocław, but we assist clients throughout Poland and remotely from anywhere in the world.
