Capital, in legal and transactional practice, generally refers to the financial resources or assets contributed to, or retained within, a business or other entity to fund its operations and growth. It commonly encompasses share capital, loan capital, and other equity or debt funding, and may extend to assets such as property or equipment used in the business.In company law across England and Wales, Scotland, Northern Ireland and Ireland, “share capital” and “issued share capital” are defined and regulated concepts (for example, under the Companies Act 2006 in the UK and the Companies Act 2014 in Ireland), governing matters such as maintenance of capital, distributions, reduction of capital and rights attaching to shares.In trust and probate practice, capital is distinguished from income, affecting beneficiaries’ respective entitlements and trustees’ investment and distribution decisions. In tax law, capital is contrasted with revenue for purposes including capital gains tax and capital allowances, with detailed statutory and case law rules.Usage is broadly consistent across the UK and Ireland, although specific statutory definitions and technical rules vary between jurisdictions and practice areas.
