This word signifies. to abandon, to renounce; also the act by which the renunciation is made. For example, a disclaimer is the act by which a patentee renounces a part of his title of invention.
In real actions, a disclaimer of the tenancy or title is frequently added to the plea of non tenure. If the action be one in which the demandant cannot recover damages, as formedon in the discender, the demandant or plaintiff was bound to pray judgment, etc., and enter, for thereby, he has the effect of his suit. But, if the demandant can recover damages and is unwilling to waive them, he should answer the disclaimer by averring that the defendant is tenant of the land, or claims to be such as the writ supposes, and proceed to try the question, otherwise he would lose his damages. The same course may be pursued in the action of ejectment. Yet, if the plaintiff is willing to waive his claim for damages, there is no reason why he may not ask for judgment upon the disclaimer without trial, for thereby he has the effect of his suit.
Chancery Pleading. The renunciation of the defendant to all claims to the subject of the demand made by the plaintiff's bill. A disclaimer is distinct in substance from an answer, though sometimes confounded with it, but it seldom can be put in without an answer for if the defendant has been made a party by mistake, having had an interest which be has parted with, the plaintiff may require an answer sufficient to ascertain whether that is the fact or not.
Estates. The act of a party by which be refuses to accept of an estate which has been conveyed to him.
It is said, that a disclaimer of a freehold estate must be in a court of record, because a freehold shall not be divested by bare words, in pais.
A disclaimer of tenancy is the act of a person in possession, who denies holding the estate from the person claiming to be the owner of it.
