FAQs
Which documents can you certify or attest?
We certify and attest financial statements, net worth and turnover certificates, bank and solvency certificates, tax and income proofs, and business registration documents. We also assist with embassy and visa-related certifications.
Why do I need certification or attestation of documents?
It confirms your documents’ authenticity for legal, financial, or cross-border use whether for loans, visas, government approvals, or overseas operations.
How long does the process take?
Most certifications are completed within 2–5 business days. Attestations involving external authorities may take longer, and we’ll share timelines in advance.
What is required from me to get started?
Share scanned or original documents with valid ID. We’ll verify them, confirm the authority involved, and provide the estimated delivery time.
Do you handle multi-jurisdiction or cross-border attestations?
Yes. We manage attestations across states and countries through our global network, ensuring full compliance with regional and international requirements.
How do you ensure document security and authenticity?
We maintain strict confidentiality, use secure transfer channels, and complete all certifications through authorized professionals only.
What if a document is laminated or damaged?
We’ll assess its condition and guide you on the best approach such as de-lamination or notarized copies to avoid rejection.
Can you handle the attestation if I’m abroad?
Yes. With your authorization and ID verification, we can complete the entire process on your behalf and ship the documents securely.
Will all countries or states accept your certification or attestation?
Our certifications are widely accepted by banks, embassies, and authorities. For countries needing extra legalization or apostille, we can assist with that too.
What if the document is not in English or needs translation?
We can arrange certified translations through our network of authorized translators. Once translated, the document will be verified and attested as per the required authority’s guidelines.
