In law, a liquidator is the officer appointed when a company goes into winding-up or liquidation who has responsibility for collecting in all of the assets under such circumstances of the company and settling all claims against the company before putting the company into dissolution. Liquidator is a person officially appointed to 'liquidate' a company or firm. Their duty is to ascertain and settle the liabilities of a company or a firm. If there are any surplus, then those are distributed to the contributories. In English law, the term "liquidator" was first used in the Joint Stock Companies Act 1856. Prior to that time, the equivalent role was fulfilled by "official managers" pursuant to the amendments to the Joint Stock Companies Winding-Up Act 1844 passed in 1848 - 1849. In most jurisdictions, a liquidator's powers are defined by statute. Certain powers are generally exercisable without the requirement of any approvals; others may require sanction, either by the court, by an extraordinary resolution (in a members' voluntary winding up) or the liquidation committee or a meeting of the company's creditors .In the United Kingdom, see sections 165-168 of the Insolvency Act 1986 The liquidator would normally require sanction to pay and to make compromises or arrangement with creditors. Without sanction , the liquidator may carry on legal proceedings and carry on the business of the company so far as may be necessary for a beneficial winding-up. Without sanction, the liquidator may sell company property, claim against insolvent contributories, raise money on the security of company assets, and do all such things as may be necessary for the winding-up and distribution of assets. In compulsory liquidation, the liquidator must assume control of all property to which the company appears to be entitled. The exercise of their powers is subject to the supervision of the court. They may be compelled to call a meeting of creditors or contributories when requested to do so by those holding above the statutory minimum.
