To transfer shares of stock, the current owner signs a stock power endorsing the shares to the new owner, obtains a Medallion signature guarantee, and delivers that stock power together with the original certificate (or an electronic transfer request) to the corporation or its transfer agent. The company then verifies any internal restrictions, cancels the old certificate, updates the stock ledger, and issues a new certificate or book-entry statement in the recipient’s name. The mechanics are straightforward, but the paperwork, corporate approvals, federal securities rules, and tax reporting all have to line up before the transfer is effective.
Documents That Start the Transfer
Every transfer begins with paperwork identifying who is giving up the shares, who is receiving them, and on what terms. A sale uses a stock purchase agreement setting the price per share, the total number of shares, and any closing conditions. A gift uses a written deed of gift or gift letter documenting the donor’s intent to transfer without payment. Either document should carry each party’s full legal name, mailing address, and taxpayer identification number, because the IRS needs that information for cost-basis and gift-tax reporting.
The Stock Power
Under UCC Article 8, endorsing a stock certificate does not complete a transfer until the endorsed certificate is physically delivered to the new owner. The endorsement can appear on the back of the certificate itself or on a separate document called a stock power. Most people use the separate form so the certificate stays clean. The stock power identifies the shares by class (common or preferred) and certificate number, names the new owner, and carries the transferring owner’s signature.
When the endorsement sits on a separate document, the transfer is not valid until both the stock power and the certificate are delivered together.1Cornell Law School. Uniform Commercial Code 8-304 – Indorsement Sending a signed stock power by one route and the certificate by another actually functions as a security measure: neither piece by itself can move ownership.
If the Certificate Is Missing
The original certificate has to be surrendered to the corporation or transfer agent. If it has been lost or destroyed, the registered owner files an affidavit describing the loss and purchases an indemnity bond that protects the corporation if the missing certificate ever resurfaces in someone else’s hands. The bond typically costs between two and three percent of the shares’ current market value.2Investor.gov. Lost or Stolen Stock Certificates That is a meaningful expense on a large holding, so search old files and safe deposit boxes carefully before assuming the certificate is gone.
Signature Guarantee
Transfer agents are generally required to obtain a signature guarantee before processing a transfer, and federal rules allow them to reject a request if the guarantor is not a member of a recognized signature guarantee program.3eCFR. 17 CFR 240.17Ad-15 – Signature Guarantees The Medallion Signature Guarantee is the most common form and is available at banks, broker-dealers, and credit unions that participate in an approved program. Each Medallion stamp has a coverage limit marked by an alpha prefix, ranging from “F” at $100,000 up to “Z” at $10 million or more. If the transaction value exceeds the stamp’s limit, the transfer agent will reject it. A notary acknowledgment is not a Medallion guarantee and is generally not accepted for securities transfers, though some small private corporations may accept notarization for internal share transfers under their bylaws.
Corporate Approvals and Transfer Restrictions
Before submitting anything, read the corporation’s governing documents. Articles of incorporation, bylaws, and shareholder agreements often limit who can receive shares and on what terms. These restrictions show up most in closely held companies, where existing owners want control over who joins the ownership group.
The most common restriction is a right of first refusal, which lets the corporation or the other shareholders buy the shares on the same terms offered by an outside buyer before the sale can close. Others require board approval for any transfer, limit transfers to family members, or prohibit transfers that would break a tax election such as S corporation status. A restriction is generally enforceable against a buyer only if it appears conspicuously on the stock certificate itself. If nothing on the certificate flags the restriction and the buyer had no actual knowledge of it, the restriction usually will not bind that buyer.
When board consent is required, the board authorizes the transfer either by resolution at a meeting or by written consent in lieu of a meeting. The resolution names the transferring shareholder, the recipient, the number and class of shares, and the effective date, and it directs the corporate secretary or transfer agent to cancel the old certificate and issue a new one. Without a documented authorization on file, the corporation has no record that the change was ever approved, which becomes a problem if ownership is later disputed.
Skipping a required approval is not just an administrative issue. A transfer that violates a valid restriction can be treated as void or voidable, and a court can unwind it entirely. The buyer can lose both the shares and the purchase price. Most avoidable transfer disputes start here: a seller who assumed the shares were freely transferable and never read the shareholder agreement.
Extra Rules for Restricted and Control Shares
If the shares came out of a private placement or were acquired directly from the company rather than on the open market, they are probably “restricted securities” that cannot be resold freely without either SEC registration or an exemption. SEC Rule 144 is the most-used exemption, and its conditions differ depending on whether the seller is an affiliate, meaning someone who controls, is controlled by, or is under common control with the issuer.
For restricted shares in a company that files SEC reports, the holder must wait at least six months after acquiring and fully paying for the shares before reselling under Rule 144. For a non-reporting company, the wait is one year. The holding-period clock does not start until the purchase price is fully paid, so shares bought with a promissory note may not start accruing time until the note is discharged, unless the note meets specific collateral and recourse conditions.4eCFR. 17 CFR 230.144 – Persons Deemed Not to Be Engaged in a Distribution Affiliates also face a volume cap in any rolling three-month period: the greater of one percent of the outstanding shares of the class or, for exchange-listed stock, the average reported weekly trading volume over the preceding four weeks. Over-the-counter shares use only the one-percent measure.5U.S. Securities and Exchange Commission. Rule 144 – Selling Restricted and Control Securities
Restricted shares carry a legend on the certificate stating that they cannot be sold without registration or an exemption. Before the shares can transfer freely, the legend has to be removed by the transfer agent, and the transfer agent will not act without consent from the issuer, typically an opinion letter from company counsel confirming that the conditions for resale are met. If a dispute breaks out with the issuer over legend removal, the SEC generally does not step in; those disputes are governed by state law.6U.S. Securities and Exchange Commission. Restricted Securities – Removing the Restrictive Legend
Recording the Transfer and Issuing New Shares
Once approvals are in place and the documentation is complete, the corporate secretary or transfer agent processes the change. The surrendered certificate is canceled, usually by physical stamp or permanent marking, and archived. A new certificate is printed in the recipient’s name and signed by the authorized officers. For companies that still issue paper certificates, that typically means the president and the secretary.
The corporation’s stock ledger is then updated with the new shareholder’s name, address, number and class of shares, and the transfer date. That ledger entry is the moment the corporation officially recognizes the new owner for voting rights and dividend payments. Under UCC Article 8, an issuer that fails to register a valid transfer within a reasonable time is liable for any resulting loss to the person presenting the certificate.7Legal Information Institute. Uniform Commercial Code 8-401 – Duty of Issuer to Register Transfer
Electronic and Brokerage-Held Shares
Many publicly traded companies now use the Direct Registration System (DRS), which lets shareholders hold securities in book-entry form directly on the issuer’s books. Instead of a paper certificate, the shareholder receives a statement of ownership showing the number and type of shares held.8SEC.gov. Transfer Agents Operating Direct Registration System Transferring DRS shares means submitting a transfer request to the transfer agent along with a stock power and the required signature guarantee. There is no certificate to surrender.
For shares held in a brokerage account, transfers between firms usually move through the Automated Customer Account Transfer System (ACATS). A clean ACATS transfer completes in about six business days from the receiving firm’s request, though total time including account setup can stretch to two or three weeks.9U.S. Securities and Exchange Commission.

Tax Consequences
How you transfer shares determines who pays tax, how much, and when. This is where the most expensive mistakes happen, and it is often the piece people think about last.
Sales
Selling shares produces a capital gain or loss equal to the difference between the sale price and your cost basis. Long-term gains apply when shares are held longer than one year and are taxed at preferential federal rates; short-term gains, on shares held one year or less, are taxed at ordinary income rates. Brokers and transfer agents report sales on Form 1099-B, including the cost basis for covered securities (generally stock acquired for cash in a brokerage account after 2010). When securities move between brokers or transfer agents, the transferring institution must furnish a written transfer statement within 15 days of settlement showing the adjusted basis, original acquisition date, and any holding-period adjustments.10Internal Revenue Service. Instructions for Form 1099-B (2026) If that statement never reaches the receiving broker, the shares may be treated as noncovered and the basis-reporting burden shifts to you.
Gifts
Giving shares away triggers no income tax at the time of the gift, but the recipient inherits the donor’s cost basis. Stock bought for $10 a share and gifted at $50 leaves the recipient with a $10 basis for computing a future gain.11Office of the Law Revision Counsel. 26 USC 1015 – Basis of Property Acquired by Gifts and Transfers in Trust There is a special rule for losses: if the fair market value at the time of the gift is lower than the donor’s basis, the recipient uses that lower fair market value as the basis for computing any later loss. That prevents donors from handing off unrealized losses.
For gift tax reporting, an individual can give up to $19,000 per recipient in 2026 without filing a gift tax return.12Internal Revenue Service. What’s New – Estate and Gift Tax Above that, IRS Form 709 is required, though actual gift tax generally does not apply unless a significant portion of the lifetime exemption has already been used.
Inherited Shares
Shares received through an estate get a different treatment. The recipient’s basis is generally the fair market value on the date of the decedent’s death, not the price the decedent originally paid.13Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent This “stepped-up basis” can erase decades of unrealized appreciation. Shares a parent bought for $5,000 that are worth $200,000 at death give the heir a $200,000 basis, and a sale immediately after inheritance produces little or no taxable gain. The executor typically works with the transfer agent to re-register the shares in the heir’s name, using letters testamentary or letters of administration as proof of authority.
Mistakes That Stall or Void a Transfer
A handful of errors show up over and over. Any one of them can hold up an otherwise clean transfer.
- Name mismatches. The signature on the stock power must match the name on the certificate exactly. A certificate reading “Robert J. Smith” signed as “Bob Smith” will be rejected. Legal name changes need supporting documents.
- Ignoring transfer restrictions in the bylaws or shareholder agreement. A valid restriction that gets bypassed can unwind the whole transaction.
- Using a Medallion stamp with a coverage limit below the transaction value. The transfer agent will send it back until a higher-prefix stamp is obtained.
- Losing track of tax basis records, especially for gifted shares where the donor’s basis carries over. Missing basis information often means overpaying capital gains tax years later.
- Trying to resell restricted securities before the Rule 144 holding period ends. The transfer agent will not lift the legend, and selling without an exemption creates securities-law exposure.
Each of these is catchable with a careful review before the package leaves your hands. The time to spot a name discrepancy or an unmet approval is before submission, not weeks later when a rejection notice arrives.
