Restitution 
          
          Under ancient English common law, when a party enforced a court judgement 
          and then that judgement was overturned on appeal, the appellant could 
          ask the appeal court for "restitution", or financial compensation 
          placing that appellant in the same position as if the original legal 
          decision had not been enforced. A new strain of common law has also 
          developed called "restitution", closely associated with unjust 
          enrichment, whereby a person is deprived of something of value belonging 
          to them, can ask a court to order "restitution". The best 
          example is asking a court to reverse or correct a payment made in error. 
          
        Resulting 
          trust 
          A trust that is presumed by the court from certain situations. Similar 
          to a constructive trust but for resulting trusts, the court presumes 
          an intention to create a trust; the law assumes that the property is 
          not held by the right person and that the possessor is only holding 
          the property "in trust" for the rightful owner. In constructive 
          trusts, the courts don't even bother with presuming an intention; they 
          simply impose a trust from the facts. 
        Retainer 
          
          A contract between a lawyer and his (or her) client, wherein the lawyer 
          agrees to represent and provide legal advice to the client, in exchange 
          for money. The signed retainer begins the client-lawyer relationship 
          from which flow many responsibilities and duties, primarily on the lawyer, 
          including to provide accurate legal advice, to monitor limitation dates 
          and to not allow any conflict of interest with the relationship with 
          the client. 
        Reversion 
          
          A future interest left in a transferror or his (or her) heirs. A reservation 
          in a real property conveyance that the property reverts back to the 
          original owner upon the occurence of a certain event. For example, Jim 
          gives Bob a bulding using the words "to Bob for life". Upon 
          the death of Bob, the property reverts back to Jim or to Jim's heirs. 
          Differs from a remainder in that a remainder takes effect by an act 
          of the parties involved. A reversion takes effect by operation of the 
          law. Nor is a reversion a "left-over" as is a remainder. Rather, 
          it reverts the entire property. 
        Riparian 
          rights 
          Special rights of people who own land that runs into a river bank (a 
          "riparian owner" is a person who owns land that runs into 
          a river). While not an ownership right, riparian rights include the 
          right of access to, and use of the water for domestic purposes (bathing, 
          cleaning and navigating). The extent of these rights varies from country 
          to country and may include the right to build a wharf outwards to a 
          navigable depth or to take emergency measures to prevent flooding.
