State Law

While you don't have to be registered as an HOA in Texas, you are probably incorporated and registered with the state agency that handles corporations. If you are a corp, then you probably are required to have at least, an annual meeting of the members, but your documents may call for more, or other meetings.

Sec. 22.154. FAILURE TO CALL ANNUAL MEETING.A (a) If the
board of directors of a corporation fails to call the annual meeting
of members when required, a member of the corporation may demand
that the meeting be held within a reasonable time. The demand must
be made in writing and sent to an officer of the corporation by
registered mail.
(b)If a required annual meeting is not called before the
61st day after the date of demand, a member of the corporation may
compel the holding of the meeting by legal action directed against
the board of directors, and each of the extraordinary writs of
common law and of courts of equity are available to the member to
compel the holding of the meeting. Each member has a justiciable
interest sufficient to enable the member to institute and prosecute
the legal proceedings.
(c)Failure to hold a required annual meeting at the
designated time does not result in the winding up and termination of
the corporation.
