Corporate Stock-Transfer Restriction and Certificate-Legend Requirements in South Dakota

At a glance

Requirements one by one

General restriction authorization and earlier-issued shares

S.D. Codified Laws § 47-1A-627 permits a restriction in the articles of incorporation, bylaws, an agreement among shareholders, or an agreement between shareholders and the corporation. A share issued before adoption is unaffected unless its holder is a party to the restriction agreement or voted for the restriction.

Unlike many states' single-section presentation, South Dakota places the notice, purpose, and permitted-form rules in §§ 47-1A-627.1 and 47-1A-627.2. Those surveyed provisions do not separately define shares to include a convertible or subscription-right security.

Permitted purposes and forms

Section 47-1A-627.1 authorizes restrictions used to maintain a corporate status dependent on shareholder number or identity, preserve a federal or state securities-law exemption, or serve another reasonable purpose.

Section 47-1A-627.2 lists a first offer to the corporation or other people; an obligation for the corporation or other people to acquire the shares; approval by the corporation, holders of a class, or another person; and a prohibition involving designated people or classes. The offer and acquisition routes may operate separately, consecutively, or simultaneously. Approval and designated- person terms must not be manifestly unreasonable.

The surveyed provisions do not separately prescribe an ownership percentage cap, mandatory or automatic transfer, tax-attribute or general regulatory- compliance route, purchase price, valuation formula, funding method, or remedy.

Corporate and UCC notice rules

An authorized general restriction is valid and enforceable against the holder or the holder's transferee when its existence is noted conspicuously on the certificate or included in the written information statement for uncertificated shares. Without that notice, § 47-1A-627.1 says it is not enforceable against a person without knowledge.

South Dakota's UCC defines “knowledge” as actual knowledge in § 57A-1-202(b). Section 57A-8-204 separately makes an issuer-imposed restriction ineffective against a person without actual knowledge unless a certificated security conspicuously notes the restriction or the registered owner of an uncertificated security was notified.

Unless the articles or bylaws provide otherwise, § 47-1A-626 lets the board authorize some or all classes or series without certificates. Existing certificates remain until surrender. Within a reasonable time after an uncertificated issue or transfer, the corporation sends the shareholder the applicable certificate and restriction information.

Unanimous shareholder-agreement overlay

Sections 47-1A-732 and 47-1A-732.1 cover a special shareholder agreement. It must be in the articles or bylaws and approved by all current shareholders, or in a written agreement signed by all current shareholders and made known to the corporation. Amendment ordinarily requires all current shareholders unless the agreement provides otherwise. The default term is 10 years, again unless the agreement provides otherwise.

The agreement's existence must be noted conspicuously on each outstanding certificate or on the uncertificated-share information statement. Existing certificates must be recalled and replaced. Missing notice does not invalidate the agreement or an action under it, but a purchaser without knowledge is entitled to rescind. Certificate or statement notice, plus delivery of the statement at or before an uncertificated purchase, deems the purchaser to have knowledge. The rescission action is due by the earlier of 90 days after discovery or two years after purchase.

Section 47-1A-732.3 ends the agreement when shares become listed on a national securities exchange or regularly traded in the specified market. It also permits a board cleanup amendment without shareholder action when the ended agreement was contained or referred to in the articles or bylaws.

What trips people up

South Dakota split the standard provisions into multiple sections. A check of § 47-1A-627 alone misses notice, authorized purposes, and permitted forms; those rules continue through § 47-1A-627.2.

The general and unanimous-agreement consequences differ. Missing general restriction notice prevents enforcement against a protected person. Missing special-agreement notice does not invalidate the agreement or action under it; it creates a purchaser's time-limited rescission right.

The public-market cutoff is specific. The special agreement ends on national-exchange listing or regular trading in a market maintained by members of a national or affiliated securities association.

Common questions

May a South Dakota restriction appear in the bylaws?

Yes. Section 47-1A-627 expressly names the bylaws. A qualifying section 47-1A-732 agreement may also be placed there, but all current shareholders must approve it.

May South Dakota require the corporation to buy restricted shares?

Yes. Section 47-1A-627.2(2) permits a restriction obligating the corporation or other people, separately, consecutively, or simultaneously, to acquire the shares. It does not set the trigger, price, valuation method, funding, or remedy.

How long does the special shareholder agreement last?

The default is 10 years under § 47-1A-732.1(3), but the agreement may provide a different term. The public-market cutoff in § 47-1A-732.3 remains separate.

Can South Dakota shares be issued without certificates?

Yes, when the articles or bylaws do not provide otherwise. Section 47-1A-626 preserves existing certificates until surrender and requires the written information statement after an uncertificated issuance or transfer.
