Marc Edmond Jones in his book Horary Astrology, describes the 7th house as follows:
"The seventh house is important because it indicates the major relationships, in joint interest or equal status, of people and things linked together in any immediate crisis or problem.
This means all direct partnerships and contracts, such as in marriage or business, and also the equally direct contact in opposition represented by disputes, contests, warfare and conflicts of every sort, whether in enmity or friendship.... the basic idea is simple cooperation, of which the commonest manifestation is marriage. It is thus quite impartial in disclosing the reciprocal activities of life as both co-operative and unfriendly, and in showing competitors and competition as both menace and stimulation or opportunity. It fundamentally indicates the critical focus of a general potentiality in any question or crisis, or the immediate concern of everything else in general with that matter which has been brought to the point of consultation or conference.... All legal action is placed in the seventh house, including the lawyers on both sides; but with the judge taken as an umpire and located in the tenth, and with the jury... assigned to the eleventh as the special "resource" of the magistrate or legal jurisdiction... In the rare instance where it is necessary to differentiate between the attorneys for the plaintiff and defendant in a lawsuit, the querent's legal representation is found in the normal position at the seventh, and the opponent's lawyer or lawyers are identified by the first."
