English trust law concerns the creation and protection of asset funds, which are usually held by one person for someone else's benefit. Trusts were a creation of the English law of property and obligations, but also share a history with countries across the Commonwealth and the United States. Trusts developed when claimants in property disputes were dissatisfied with the common law courts and petitioned the King for a just and equitable result. On the King's behalf, the Lord Chancellor developed a parallel justice system in the Court of Chancery. Historically, trusts were mostly used where people left money in a will, created family settlements, created charities, or some types of business venture. After the Judicature Act 1873, England's courts of equity and common law were merged, and equitable principles took precedence. Today, trusts play an important role in financial investments, especially in unit trusts and pension trusts, where trustees and fund managers usually invest assets for people who wish to save for retirement. Although people are generally free to write trusts in any way they like, an increasing number of statutes are designed to protect beneficiaries, or regulate the trust relationship, including the Trustee Act 1925, Trustee Investments Act 1961, Recognition of Trusts Act 1987, Financial Services and Markets Act 2000, Trustee Act 2000, Pensions Act 1995, Pensions Act 2004 and the Charities Act 2011.
