I need to purchase a new boiler because the previous one broke. I share 50/50 ownership in New Jersey with someone who decided dealing with the upkeep of a house was too much, having said that I have been living in and maintaining the house for 8 months alone. To get a boiler I am told that I need the other owner's signature because they consider this to be a home improvement, which I consider maintenance; if I don't get a boiler I will freeze, how is that an improvement? Is their any way around getting the other person's signature?
