Who are you joining?

It depends on your spouse's status. Joining a Polish citizen spouse and joining a foreigner spouse who already holds their own Polish residence status are two different legal routes with two different document checklists -- they are not interchangeable.

A current marriage certificate, evidence of your Polish spouse's citizenship, biometric photos, evidence of stable income, health insurance, secured accommodation, and your passport -- submitted via MOS.

Your sponsoring spouse must first qualify: they need to hold a permanent residence permit, EU long-term resident status, refugee status, subsidiary protection, humanitarian-stay consent, or a temporary residence permit held continuously for at least 2 years (with the most recent grant at least 1 year). If they don't hold one of these, this route may not currently be available to you.

For the spouse-of-a-Polish-citizen route, widely-observed office practice expects a marriage certificate copy issued no earlier than 3 months before you submit your application.

Not always. Whether an apostille or legalisation is needed depends on the country that issued the document. There is no single universal answer -- treat any claim that "every foreign marriage certificate needs an apostille" with caution.

Generally, no. EU Regulation 2016/1191 removes the apostille/legalisation requirement for certain public documents -- including marriage, birth, and civil-status documents -- issued by one EU member state and presented to the authorities of another, such as Poland.

Not necessarily. Recording a foreign marriage in the Polish civil registry (a process called transcription, "transkrypcja") is a separate process -- no source found ties it to a foreign spouse's residence-permit eligibility. It's mainly relevant to the Polish citizen spouse's own civil-status records, identity documents, or PESEL registration.

Possibly, once you meet both a marriage-duration and a residence-duration condition -- but this is general orientation, not a personal eligibility check.

An apostille is a standardized certificate issued by a competent authority in the country where a document was produced, confirming the authenticity of the signature, the capacity in which the signer acted, and the seal/stamp on the document. It's issued under the 1961 Hague Apostille Convention and is meant to let a public document from one member country be recognized in another without full consular legalisation.

They solve two different problems and neither replaces the other. An apostille (or legalisation) authenticates the document itself -- proving the signature, seal, and issuing authority are genuine. A sworn translation makes the document's content usable in Polish, by a translator authorized to certify accuracy.

As a general rule, any document in a foreign language submitted to a Polish public authority needs to be translated by a sworn translator (tłumacz przysięgły) registered with the Ministry of Justice -- Polish public institutions generally only accept translations from this registered pool.

The office handling a spouse-of-Polish-citizen temporary residence application is required to assess whether the marriage was concluded to circumvent the Act on Foreigners (a sham-marriage check), not merely to confirm the certificate is genuine.
