What are the requirements for granting powers of attorney for the representation of an estate (succession of heirs)?

To grant powers of attorney on behalf of an estate, all heirs must sign a power of attorney designating a common representative with authority over shareholder- related matters. If the power of attorney includes the authority to sell shares or collect dividends, it must be granted either by a private instrument notarized before a notary public or by a public deed.

Additionally, if any of the heirs are women, their marital status must be certified by either a marriage certificate or a sworn statement by two witnesses before a notary. If the woman is married under community property regime, her husband must also grant power of attorney to authorize the sale of shares. Finally, if the marriage has been dissolved, a certificate must be provided stating that the heir has not remarried.
