All right, you will receive the agenda for the meeting together with the confirmation letter stating the date and time of the meeting. This is ussually done about 15 days prior to the meeting. If you want something to be included in that agenda you should do it before that, you have to tell it to the president (or the administrator if you don't know the president). Administrator's email is: mm.asesores at terra. es and his name is Francisco Mulero, phone number is +34968211668. Just be careful with the address given to the administrator (normally by the developer), because if it's wrong you'll never get the letter or any other communications.
In order to vote you have two options: 1. being there and vote personally; 2. name a representative for the meeting, ussually another neighbor that will vote for you. Only in really important issues (like if the community was thinking about a really large investment for something, for example) you would have the possibility to vote afterwards (I think ten days after the meeting), should your vote go contrary to what was voted and accepted.
Regarding the developer's share, normally a voting for the most important issues is a product of two majorities: 1. Accounting for the number of shares you have on the building (33% in case of Oasis the developer); 2. Accounting for the number of owners (1 in the case of the developer). You need majority in both equations, so the developer can't do whatever he wants, because he would fail in the second majority. For normal votings, for really day-a-day issues I think it's enough with the first majority. We are legally studying the conflict of interest, for example in the next meeting we will be discussin if to pay or not the electricity charges the developer paid until we all could get the contract with Iberdrola (the electric company). These expenses, total amount 15.000€, can not be requirable to the community, due to the fact that we all could have rejected the signing of our deed until we could personally contract the electric service, and the developer is forced to pay for this and all the other necessary supplies. Oasis is kindly asking if we would agree to pay this quantity, but there are some concerns:
1. They have made this calculation themselves, the 15,000€ come from an inhouse calculation, and those are estimated quantities.
2. This electric bill hasn't been paid directly by the developer, it has been paid by a third party, the builder.
3. By signing all the deeds before time, the developer has saved an important amount of money in financial interests from his mortgage loan, so they were the most interested party in signing the flats. In the other hand, they have to pay for all the common supllies until all the owner can contract this by themselves.
4. In addition to the self calculation of this amount, they haven't paid this quantity to the community for this amount in terms of fees from their apartments, so they have self calculated and self liquidated this quantity. Kind of difficult to explain.
That's why I'm saying that it is important that we all be there at the meeting, we need to vote against this. I think that most of the owners agree that we should no pay this quantity to the developer, nobody can require us to pay this.
Best regards.
