the event of contractor insolvency, this makes it much more likely that subcontractors will be paid for work completed. Legal retainer – Lawyers in certain countries often require that a legal retainer be paid upfront and held in trust until such time as the legal work is performed and billed to the client, this serves as a minimum guarantee of remuneration should the client become insolvent. However, strict legal ethical codes apply to the use of legal retainer trusts. Types Trusts go by many different names, depending on the characteristics or the purpose of the trust. Because trusts often have multiple characteristics or purposes, a single trust might accurately be described in several ways. For example, a living trust is often an express trust, which is also a revocable trust, and might include an incentive trust, and so forth. Alphabetic list of trust types Asset-protection trust: The concept of an asset-protection trust encompasses any form of trust that provides for funds to be held on a discretionary basis. Such trusts are set up in an attempt to avoid or mitigate the effects of taxation, divorce and bankruptcy on the beneficiary. Such trusts may be proscribed or limited in their effect by governments and the courts. Constructive trust: Unlike an express trust, a constructive trust is not created by an agreement between a settlor and the trustee. A constructive trust is imposed by the law as an "equitable remedy". This generally occurs due to some wrongdoing, where the wrongdoer has acquired legal title to some property and cannot in good conscience be allowed to benefit from it. A constructive trust is, essentially, a legal fiction. For example, a court of equity recognizing a plaintiff's request for the equitable remedy of a constructive trust may decide that a constructive trust has been created and simply order the person holding the assets to deliver them to the person who rightfully should have them. The constructive trustee is not necessarily the person who is guilty of the wrongdoing, and in practice it is often a bank or similar organization. The distinction may be finer than the preceding exposition in that there are also said to be two forms of constructive trust, the institutional constructive trust and the remedial constructive trust. The latter is an "equitable remedy" imposed by law being truly remedial; the former arising due to some defect in the transfer of property.
