The percentage of ownership of the property is not the determining factor. The court will consider the need to sell the residence in order to provide funds for each of the parties. You may be able to acquire his portion of the property by providing him with some other equally valuable asset. By introducing your daughter as an additional owner. you are making the possibility of sale more difficult for the court to order. The court will struggle to find jurisdiction over your daughter, in order to force her to sell her portion.
If you are living in the New York City metropolitan area, please call me at 212-370-1660 to arrange for a meeting to discuss the matter at greater length.
