A Dictionary of Law
In its ordinary sense, to disable is to cause a disability, (q. v.) In the old language of pleading, to disable is to take advantage of one's own or another's disability. Thus, it is "an express maxim of the common law that the party shall not disable himself;" but "this disability to disable himself * * * is personal."
