not sure if you have solved this already, but....there are laws governing the behavior of HOA’s, YET these associations can still have a powerful impact on your rights as homeowner.
Firstly: State laws establish what happens when homeowners do not pay their homeowners' association assessments or dues. And in Hawaii i believe that you can place a lien.
Secondly; there are written documents for you to read to help you mom. they may also have language which will govern how late fees are assessed etc. Please I highly recommend you get copies of these pdf'ed to youas soon as possible (OR just go on the home owners assoc website to download, i have provided a link to such an example association so you can get the idea of what your mom's might look like. ) http://www.waikoloa.org/wva Anyways learn your moms HOA’s Rules and Regulations and you may also find the HOA’s CC&R’s (covenants, conditions, and restrictions) online as well as information about what happens if you violate a rule. Moreover, they might publish minutes from meetings on line as well.
Thirdly and maybe most importantly, they are very helpful in the state of Hawaii govt offices. give them a call to get the right department. Sate of Hawaii's consumer resource center is 808 587 3222; and consumer protection office is 808 586 2630. These are good places to start.
from another with a mom in hawaii...
Technically, the HOA do have the right to put a lien on the property, but in this case, they may have an error that you need to dig in further.
