We live in a "developed estate" what really is a village with several homes. There recently was an extraordinary meeting that we believe violated numerous regulations. I am aware that land office filing must be done within 30 days of the date of that meeting

However, I know that a homeowner can file a motion with the court objecting to the meeting. Does anyone know if that motion also has to be within 30 days of the date of the meeting or within 30 days from the date the request for approval at the land office is filed.

You would probably do best to ask the Land office, as they may have their own local rules etc. I don't think its actually written down anywhere. I know in the past, I have seen EGMs lodged on the 29th day, so that there isn't much time to dispute.
