When submitting documents in paper format, it is necessary to certify the signatures on the partition of the participant register, the new version of the articles of association, the minutes of the meeting of participants or the decision.

Signatures may be certified as follows:

• At a sworn notary
• In the Orphan's Court, after the declared place of residence (if the person has the personal identity number of the Republic of Latvia), if there is no notary in the county, county city or county parish
• When signing documents with a secure electronic signature and time stamp. Where a document is to be signed by more than one person, it may be provided electronically only if all the signatories have an electronic signature.
