Legal Question in Real Estate Law in Iowa

Tell him to take it down. Have you had a survey performed? Get one so there is no question about the lot line. Then serve him with notice to remove it.

Get a survey, since sometimes the lot line is not where you think it is. Is the fence actually a problem for you? If not, have an attorney help you granting your neighbor what is called a license. This will prevent his encroachment from ripening into an easement or ownership. If the fence in on your property, and it is a problem for you, ask him nicely to move it. If the neighbor refuses, you will have to sue him.
