Sir,
i presume the property under reference is in Maharashtra:
[1] The assets and liabilities are primarily attached to the property and not to a person, society should have been more careful before admitting you as member, however that does not absolve you of the previous liabilities attached to the property.
[2] If you give your flat on rent, you can keep on using the parking space for your car. Your tenant may or may not be allowed to use the parking space as per the resolution adopted at the AGM.
[3] As per the Maharashtra Bye-Laws of CHS the builder/developer is mandatorily obliged to transfer the property rights to the society within four months of the registration of the society.
[4] For any and all of your grievances about the acts of the society, primarily you have to write to the society and seek explanation, and if there is no explanation given in writing, or if you are not satisfied with the explanation given, then you can make a complaint to the Dy.Registrar as per Appendix 28 of the Bye-laws of CHS, and follow up the matter with an application under RTI, if the Dy.Registrar fails to take action. There are other legal avenues of approach, but these are unnecessarily costly and time consuming.
Good luck,
Kishor Mehta
