The legal system of South Sudan
The world's newest sovereign legal system, independent since July 2011, and one built on a deliberate break from Khartoum: English was adopted as the official language and the common law as the model, displacing the Arabic-language Islamic-influenced system inherited from unified Sudan. The Judiciary Act and the Code of Civil Procedure follow common-law patterns, and precedent is recognised. Customary law is not residual here but central — the Transitional Constitution expressly recognises it as a source, statutory customary law courts operate at local level, and the great majority of disputes, particularly over marriage, cattle and land, are resolved through them. Land is vested in the people with community, public and private categories, and the tension between customary tenure and investment leases is the dominant property question.
Legal tradition
South Sudan belongs to the common law with customary law tradition. The world's newest sovereign legal system, independent since July 2011, and one built on a deliberate break from Khartoum: English was adopted as the official language and the common law as the model, displacing the Arabic-language Islamic-influenced system inherited from unified Sudan. The Judiciary Act and the Code of Civil Procedure follow common-law patterns, and precedent is recognised. Customary law is not residual here but central — the Transitional Constitution expressly recognises it as a source, statutory customary law courts operate at local level, and the great majority of disputes, particularly over marriage, cattle and land, are resolved through them. Land is vested in the people with community, public and private categories, and the tension between customary tenure and investment leases is the dominant property question.
How power is divided
Decentralised in form, with states and administrative areas whose number has changed repeatedly — from ten at independence to twenty-eight, then thirty-two, and back to ten plus administrative areas under the 2018 agreement. Local government includes county and payam tiers and statutory customary authorities.

The legal profession
Advocates are admitted through the Ministry of Justice and represented by the South Sudan Bar Association, and the profession is small relative to need, with many practitioners trained in Uganda, Kenya or Sudan. Judicial numbers are low and vacancies persistent, which is a large part of why customary courts carry most of the dispute-resolution load.
Law by topic in South Sudan
- Employment & LabourThe Labour Act 2017, applying to a very small formal sectorThe Labour Act 2017 replaced transitional arrangements, setting minimum conditions, leave and termination rules. Formal wage employment is a small share of work, concentrated in government, oil and aid organisations.
- Immigration & NationalityA 2011 nationality act that left many people's status contestedThe Nationality Act 2011 defines South Sudanese nationality by descent and community ties. Its interaction with Sudan's simultaneous nationality amendments produced statelessness risks that remain unresolved.
- Family LawCustomary law governs most marriage and inheritance, with no unified family codeThere is no comprehensive statutory family code; marriage, divorce, bridewealth and inheritance are governed largely by the customary law of the parties' communities, applied in customary courts.
- Criminal LawA 2008 penal code, with a hybrid court for conflict crimes still not establishedThe Penal Code Act 2008 and Code of Criminal Procedure 2008 govern. Chapter V of the 2018 peace agreement provided for a Hybrid Court for South Sudan with the African Union, which has not been established.
- Tax LawThe Taxation Act 2009 over an economy where oil supplies nearly all revenueThe Taxation Act 2009, as amended, provides for personal and business profit tax, excise and a sales tax rather than a full VAT. Oil revenue has historically supplied the overwhelming majority of government income.
- Constitutional LawA transitional constitution from 2011 whose timetable has repeatedly slippedThe Transitional Constitution 2011, amended to incorporate the 2018 Revitalised Peace Agreement, remains in force well past its intended life. A permanent constitution-making process and elections have been repeatedly postponed.
- Business & CorporateA 2012 Companies Act, oil-dependent revenue and thin commercial institutionsThe Companies Act 2012 and Investment Promotion Act 2009 provide the framework, drafted on common-law models. Oil accounts for the overwhelming share of exports and government revenue, and non-oil commercial activity is small.
- Property & LandLand belongs to the people, administered through communities under the 2009 Land ActThe Land Act 2009 vests land in the people of South Sudan and recognises community land alongside public and private categories. Customary tenure governs most holdings, and displacement has made competing claims widespread.
- Civil ProcedureA 2007 procedure act, a common-law hierarchy, and customary courts doing most of the workThe Code of Civil Procedure Act 2007 governs statutory litigation, with a hierarchy from county courts to the Supreme Court. Customary courts resolve the majority of disputes in practice.
