DEAR BENNY: I own a condo in a two-unit building. We have always split all common expenses 50/50 per our legal documents. Recently we discovered a leak in the common garage, and have established the cause and are embarking on repairs. This leak also caused dry rot in some of the hardwood floors in my unit. I considered this to be a common expense and expected the entire cost of the repairs to be divided 50/50. The other owner disagrees and claims that because the damage is in the interior of my unit I must bear the cost of those repairs myself. Your advice will be most helpful.
