Dear Mister Condo,
Mister Condo replies:
M.D., that is entirely dependent on what your governing documents state as requirements for serving on the Board. Typically, but not always, the requirement is unit ownership. If that is the case and the sibling is not a unit owner, then the answer is “no”. However, if the governing documents are silent on the subject and there are no state or local laws that prohibit the sibling from serving on the Board then the answer may be “yes”. You need to look carefully at your documents and the requirements for eligibility to serve. All the best!
