On April 17, 2025, Justice James L. Hyer of the New York Supreme Court, Westchester County, precluded a whole run of exhibits in a matrimonial case. Some had no translation at all. One translation was headed "Official Translation", but it was "not in affidavit form" and did not contain the translator's qualifications. Another, titled "Affidavit of translation", was not notarized. Accurate English, inadmissible evidence.
For attorneys, a certified translation is not one standard but several. A translation built for USCIS can fail in a state court, and a court-ready affidavit is overkill for an I-130. This reference sets out the rules by forum, what to require from a translation vendor, sample certificate language for each setting, and how to manage multi-document batches and exhibits.
What does each forum require from a certified translation?
The baseline is a full translation plus the translator's signed statement of accuracy and competence; the forums differ on form, oath and contact details.
| Forum | Rule | What the certification must contain | Notarization |
|---|---|---|---|
| USCIS | 8 CFR 103.2(b)(3) | Full translation; translator certifies it is complete and accurate and that they are competent to translate into English | Not required |
| NVC and consulates | State Department civil documents guidance | Certified translation with the translator's statement of accuracy and competence | Not required |
| US passport agencies | State Department citizenship evidence guidance | Professional translation with "a notarized letter about the accuracy of the translation and their ability to translate the document" | Required |
| Immigration court (EOIR) | 8 CFR 1003.33; Practice Manual Ch. 2.3(a) | Typed, signed; competence; "true and accurate to the best of the translator's abilities"; address and telephone number; attached to the foreign-language document | Not required |
| Federal courts | FRE 604 for interpreters; local rules and standing orders | Interpreters "must be qualified and must give an oath or affirmation to make a true translation"; for exhibits, follow local rules | Usually avoidable with a 28 USC 1746 declaration |
| New York state courts | CPLR 2101(b) | Affidavit by the translator stating qualifications and that the translation is accurate | Notarized affidavit, or an affirmation in the CPLR 2106 form |
| California state courts (civil motions) | Cal. Rules of Court 3.1110(g) | Translation "certified under oath by a qualified interpreter" | Under oath |
Two points deserve emphasis. First, the USCIS Policy Manual has a "Translations" section that, at the time of writing, is marked "[Reserved]", so the regulation is the whole federal immigration standard.
Second, New York reads CPLR 2101(b) strictly. In P.K. v. M.P., the court quoted the Second Department's 2024 decision in Reyes v. Underwood that "the conclusory certificate of translation does not contain sufficient detail" about the translator's qualifications. This table covers common baselines, not every courtroom, so check local rules and individual judges' practices.
Checklist: what to require from a translation vendor
Specify legal translation like any other expert service. Put these in your engagement terms or standing instructions:
The first two items are not theoretical. In a 2015 decision, USCIS's Administrative Appeals Office found that translations headed "Translation Excerpt" were "not full English translations or complete translations", noted that they bore "no indicia of who completed them", and gave the documents no evidentiary weight.
What should the certificate say in each forum?
USCIS and immigration court
This meets 8 CFR 103.2(b)(3) and the elements of 8 CFR 1003.33 and the Practice Manual. If one certificate covers several documents, the Practice Manual says "the certification must specify the documents"; list each by title and page range.
Federal litigation: unsworn declaration under 28 USC 1746
If the translator signs outside the United States, 28 USC 1746 prescribes different wording: "I declare (or certify, verify, or state) under penalty of perjury under the laws of the United States of America that the foregoing is true and correct." Use it whenever the translator is abroad.
New York state courts: CPLR 2101(b)
The qualifications paragraph carries the weight; a bare "I am fluent" is the kind of conclusory statement New York courts reject. To avoid the notary, CPLR 2106 now lets any person use an affirmation "in lieu of and with the same force and effect as an affidavit". End with the statutory text instead of the jurat: "I affirm this ___ day of __, __, under the penalties of perjury under the laws of New York, which may include a fine or imprisonment, that the foregoing is true, except as to matters alleged on information and belief and as to those matters I believe it to be true, and I understand that this document may be filed in an action or proceeding in a court of law."
How do you keep a multi-document batch consistent?
Lock the names before anyone translates a word, then hold every document to one style sheet. Consistency across a batch is where professional translation earns its fee.
Lock names first. Give the vendor every party's passport spelling, prior names and date of birth. A mother's surname rendered two ways across a birth certificate and a marriage certificate invites a question at the interview or a credibility argument in court.
Standardize dates. Spell out the month (March 14, 2019) so day-month order never becomes an issue.
Keep a term sheet. Court names, police ranks, degree titles and statutory references should read the same in every document. In a long asylum record, that is the difference between a coherent exhibit set and a puzzle.
Pair each translation with its original. In immigration court the certification must be "attached to the foreign-language document". The Practice Manual also says filings "should" be paginated consecutively, with a table of contents listing page numbers when proposed exhibits are submitted. See immigration court translation requirements.
Label exhibits clearly. For example: "Exhibit F: Birth certificate of respondent (Spanish original, pp. 31-32; certified English translation, pp. 33-34)".
Plan for deadlines. In immigration court, in non-detained cases the current Practice Manual requires filings to reach the court at least 30 days before an individual hearing (15 days before a master calendar hearing if you want a ruling there), unless the judge sets another deadline. Long court records and medical files take days, not hours.
How do court translations differ from USCIS translations?
USCIS reviews translations administratively: an officer reads them, and a deficient translation leads to an RFE or is given no weight. Courts are adversarial. Opposing counsel can challenge a translation, demand the translator's qualifications or offer a competing version, and the court rules on admissibility.
That makes three things matter more in litigation: a sworn or declared certificate, a translator who can be identified and called, and a translation that renders ambiguity honestly instead of resolving it silently in your client's favor. See our overview of court translation requirements in the US and our civil litigation translation service.
Common mistakes in attorney-ordered translations
- Ordering a summary translation for evidence that must be filed in full.
- Accepting a company certificate with no named translator.
- Filing a USCIS-style certificate in a court that requires an affidavit.
- Labeling a document "affidavit" without a jurat or a proper CPLR 2106 affirmation.
- Sending a non-notarized certificate with a passport application.
- Letting different vendors translate parts of one file without a shared name sheet.
- Omitting the reverse side of civil documents, where apostilles and annotations sit.
Questions people ask
Can our paralegal or interpreter translate documents for USCIS filings?
The regulation requires only a certification of accuracy and competence, so a competent staff member can technically certify a translation. The risk is that someone working for the client's counsel is not independent, which invites scrutiny of contested evidence. For decisive documents, an outside translator is the more defensible choice; see translator credentials for USCIS.
Does one certificate per batch satisfy USCIS?
The regulation does not prescribe one certificate per document, and immigration courts accept a single certificate that specifies the documents it covers. In practice a certificate per document is safer, because documents are separated, reused and refiled over the life of a case. A blanket certificate that did not list the translations it certified was one of the defects the AAO cited in 2015.
Do federal courts require notarized translations?
Generally not, because 28 USC 1746 lets an unsworn declaration under penalty of perjury stand in for a sworn statement, with narrow exceptions such as depositions. Local rules and individual judges may set their own expectations. Check the district's rules before filing.
Does a New York translation affidavit have to be notarized?
CPLR 2101(b) calls for an affidavit, and in P.K. v. M.P. an "affidavit of translation" failed partly because it was not notarized. CPLR 2106 now allows any person's affirmation, in the statutory form, to be used in place of an affidavit with the same force. Either way, the translator's qualifications must be stated in detail.
What should a translator's qualifications statement include for New York courts?
It should describe the translator's knowledge of the source language and how it was acquired, their professional translation experience, and any credentials or training. New York courts have rejected conclusory certificates that simply assert accuracy. Specific facts, such as years of legal translation work, carry more weight than adjectives.
Is ATA certification required for court or immigration work?
No US immigration rule requires it, and ATA itself says a translator does not need to be certified to provide a certified translation. It is a strong qualification to cite where qualifications must be stated. It is offered only in certain language pairs and directions, so many qualified translators cannot hold it.
How should we handle documents that are partly in English?
Translate every foreign-language element, including stamps and handwritten annotations, and mark the English parts, for example [in English in the original]. The USCIS rule covers any document containing foreign language, so a bilingual document still needs a certified translation.
What turnaround should we plan for?
We deliver a typical one-page civil document within 24 hours, and longer documents such as judgments, medical records or transcripts generally take one to three business days. Large asylum or litigation records should be scheduled against the filing deadline as a project, with names and terms agreed at the start.
How are legal translations priced?
Certified translation is usually priced per page; ours is $29.95 per page, including the signed certificate. Notarized affidavits are available as a separate service for courts and passport matters that need them.
