Talk to a real estate agent in your area, who will be familiar with the local laws.I take it the owner of the property died and left the property to his child, but the child is still a minor and his/her affairs are managed by his/her mother until the child becomes an adult.The real estate agent can order a title search for the property to see how it is owned. If the title has not been changed from the deceased father to the child, that will probably prevent the property from being sold until the estate is straightened out.
