To this end his name is associated with the Fines and Recoveries Abolition Act 1833; the Inheritance Act 1833; the Dower Act 1833; the Real Property Limitation Act 1833; the Wills Act 1837; the Copyhold Tenure Act 1841; and the Judgments Act 1838. The second was called for by the preference which the common law gave to a distant collateral over the brother of the half-blood of the first purchaser; the fourth conferred an indefeasible title on adverse possession for twenty years (a term shortened by Lord Cairns in 1875 to twelve years); the fifth reduced the number of witnesses required by law to attest wills, and removed the distinction which existed in this respect between freeholds and copyholds; the last freed an innocent debtor from imprisonment only before final judgment (or on what was termed mesne process), but the principle stated by Campbell that only fraudulent debtors should be imprisoned was ultimately given effect to for England and Wales in 1869.
