two questions: 1. If a property is owned by more than one owner, but the construction contract was entered into by only one owner who owns only a minority fractional share of the property as a tenant in common, without the joinder or approval of the other owners, may I place a lien against the whole property or only the fractional share of the one contracting owner? 2. If I serve a non-contracting owner of the property with notice of my lien, but do not serve the contracting owner, is that adequate service of notice of the lien?
