What the CBCA-CT requires

Connecticut General Statutes § 33-679 prescribes stock certificate content under the CBCA-CT. Follows the MBCA closely.

  • Corporation name (in full)
  • Statement that the corporation is incorporated under the applicable state law
  • Name of the person to whom the certificate is issued
  • Number and class or series of shares
  • Signatures of authorized officers

Restrictive notations

When shares are subject to transfer restrictions, the certificate must bear a restrictive notation. Without it, the restriction may be unenforceable against a good-faith purchaser without notice.

Uncertificated shares

Most MBCA-tradition states permit corporations to issue shares without physical certificates. In that case, the stock ledger is the proof of ownership.
