Corporate books, shareholders’ meetings, and powers of attorney up to date: evidence your company cannot afford to lose

Without books in order, the law takes your counterparty’s books as true. Without revoking powers of attorney before the third party, the company stays bound by someone who already left.

Cor­po­rate books seem like a for­mal­ity until there is a law­suit, a sale of the com­pany, or an attor­ney-in-fact who should no longer be sign­ing. At that point they become the evi­dence of who makes the deci­sions, who owns the shares, and who can bind the com­pany.

What the law requires

Every legal entity must keep a gen­eral ledger and a minute book, on paper or elec­tron­i­cally in accor­dance with the stan­dard for the reten­tion of data mes­sages (Arti­cles 33 and 34 of the Com­mer­cial Code, Código de Com­er­cio), and keep its sup­port­ing records for at least ten years (Arti­cle 38). A stock cor­po­ra­tion must also keep a share reg­is­ter and treats as owner who­ever appears reg­is­tered in it (Arti­cles 128 and 129 of the Gen­eral Law of Com­mer­cial Com­pa­nies, Ley Gen­eral de Sociedades Mer­can­tiles), as well as a cap­i­tal vari­a­tions book (Arti­cle 219). Share­hold­ers’ meet­ing min­utes may be signed by hand or elec­tron­i­cally; min­utes of extra­or­di­nary meet­ings are nota­rized and reg­is­tered with the Public Reg­istry of Com­merce (Arti­cle 194). The ordi­nary share­hold­ers’ meet­ing must be held at least once a year, within the four months fol­low­ing the close of the fiscal year (Arti­cle 181).

As for powers of attor­ney, a gen­eral power of attor­ney for acts of own­er­ship (actos de dominio) grants all the powers of an owner (Arti­cle 2554 of the Fed­eral Civil Code, Código Civil Fed­eral). If a power of attor­ney was granted to deal with a spe­cific person, the revo­ca­tion must be noti­fied to that person; oth­er­wise, the com­pany is bound by what­ever the attor­ney-in-fact does after­ward (Arti­cle 2597). Because reg­is­ter­ing powers of attor­ney with the Public Reg­istry of Com­merce is optional (Arti­cle 21, sec­tion VII, of the Com­mer­cial Code), reg­is­tra­tion does not replace noti­fi­ca­tion.

What to do and by when

  1. Hold the annual ordi­nary share­hold­ers’ meet­ing no later than April 30 if your fiscal year ends on Decem­ber 31, and record the min­utes in the book.
  2. If you keep printed books, have them bound within the three months fol­low­ing the close of the fiscal year.
  3. Rec­on­cile the share reg­is­ter with the actual trans­fers and cap­i­tal increases.
  4. Nota­rize and reg­is­ter the min­utes of every pend­ing extra­or­di­nary share­hold­ers’ meet­ing.
  5. Take an inven­tory of the powers of attor­ney in force and revoke those held by former exec­u­tives, noti­fy­ing the revo­ca­tion to the banks, clients, and sup­pli­ers they dealt with.

Recommendations to mitigate risk

If, in a com­mer­cial law­suit, a com­pany does not pro­duce its books or states that it does not have them, its oppo­nent’s books are taken as evi­dence against it (Arti­cle 1295, sec­tion III, of the Com­mer­cial Code). Acts that must be reg­is­tered and are not have effect only between the par­ties to them (Arti­cle 27), and a power of attor­ney whose revo­ca­tion was not noti­fied to the third party con­tin­ues to bind the com­pany. Keep­ing records in a lan­guage other than Span­ish, for its part, is pun­ish­able by a fine of no less than MXN 25,000, not to exceed five per­cent of the cap­i­tal (Arti­cle 37).

How we approach it at LEXURE

As part of the Blin­daje Cor­po­ra­tivo, we audit the books, min­utes, share reg­is­ter, and powers of attor­ney, and we rebuild what­ever is miss­ing. We also deliver an annual cal­en­dar of share­hold­ers’ meet­ings, reg­is­tra­tions, and power of attor­ney reviews.

If you are not cer­tain that your books would with­stand a law­suit, sched­ule a diag­nos­tic meet­ing with us.
