What is "Right, Title Interest" and "Standing?"

In the law of property, title in its broadest sense refers to all rights that can be secured and enjoyed under the law. It is frequently synonymous with absolute ownership. Title to property ordinarily signifies an estate in fee simple, which means that the holder has full and absolute ownership. The term does not necessarily imply absolute ownership, however; it can also mean mere possession or the right thereof.

Interest is the most general term that can be employed to denote a property in lands or chattels. In its application to lands or things real, it is frequently used in connection with the terms “estate,” “right,” and “title,” and it properly includes them all. More particularly it means a right to have the advantage accruing from anything; any right in the nature of property, but less than title; a partial or undivided right; a title to a share. The terms “interest” and “title” are not synonymous. A mortgagor in possession, and a purchaser holding under a deed defectively executed, have, both of them, absolute as well as insurable interests in the property, though neither of them has the legal title.

Legal standing, or locus standi, means the term for the ability of a party to demonstrate sufficient connection to, and harm from, the law or action challenged to support that party's participation in the case. The party is directly subject to an adverse effect by the statute/ordinance or action in question, and the harm suffered will continue unless the relief is granted in the form of a finding that the law either does not apply to the party or that the law is void or can be nullified. This is called the "something to lose" doctrine, in which the party has standing because they directly will be harmed by the conditions for which they are asking for relief.
