Islamic Family Abstrak Pencatatan perkawinan merupakan aspek fundamental dalam menjamin kepastian hukum dan perlindungan hak-hak keperdataan dalam sistem hukum keluarga di Indonesia. Adapun Penulisan ini bertujuan untuk menganalisis urgensi pencatatan perkawinan dalam rangka memperkuat perlindungan hukum terhadap individu dan institusi keluarga. Metode yang digunakan adalah studi pustaka dengan pendekatan yuridis, sosiologis, dan teologis terhadap peraturan perundang-undangan serta literatur hukum keluarga yang relevan. Hasil penelitian menunjukkan bahwa pencatatan yang tidak dilakukan berdampak pada ketidakjelasan status hukum pasangan dan anak, menyulitkan proses perceraian secara legal, serta melemahkan hak-hak keperdataan seperti waris dan pembagian harta bersama. Selain itu, rendahnya kesadaran hukum, faktor budaya, dan birokrasi yang kompleks menjadi kendala utama dalam pelaksanaan pencatatan. Penelitian ini menyimpulkan bahwa pencatatan perkawinan tidak hanya merupakan kewajiban administratif, melainkan juga instrumen strategis dalam menjamin keadilan sosial dan perlindungan hukum dalam kerangka negara hukum yang berkeadaban.

Keluarga Islam Introduction Marriage is a very sacred event in forming a family and establishing the rights and obligations of husband and wife, as well as being a legal path to continue 1 In addition to being recognized religiously, marriage must have clear legal legitimacy, as stipulated in Government Regulation of the Republic of Indonesia No. of 1975 precisely in article 2 paragraph 1 contains: Marriage registration of those who carry out their marriage according to their religion and beliefs other than Islam is carried out by marriage registration officers at the civil registration office as referred to in various laws regarding marriage registration. Marriage registration is presented by the state to provide legal protection to citizens and ensure the certainty of civil rights in the family. However, the practice of marriage registration in Indonesia still faces various obstacles, both internal and external. Internally, low public legal awareness is the main 3 Many individuals still consider the legality of marriage to be based on custom or religion without the need for state registration. This view, which is common in areas with low levels of education, is exacerbated by a lack of understanding of the legal implications of unregistered marriages, such as losses in inheritance rights, difficulties in proving divorce, and the legal status of children. In addition, the registration procedure, which is considered complicated, time-consuming, and costly, leads to the reluctance of the public to register the marriage officially. 4 The phenomenon of serial marriage or marriage without state registration is one of the manifestations of this Therefore, systematic efforts are needed from the government to improve registration services and carry out a cultural approach to increase public awareness of the importance of marriage registration in the context of legal protection. As a result, the marriage that took place did not have clear legal evidence. This will cause problems for the lives of married couples and even children who are not legally clear so that it will trigger difficulties in matters of inheritance rights, divorce problems, hajj, maintenance rights, distribution of joint property and even there will Rohmahtus Sholihah dan Muhammad Al Faruq.

Ahmad Fauzi, et. be uncertainty of legal protection for the family. 6 Socially, the practice of marriage like this will cause a force against gender injustice where women and children are the main victims who are greatly disadvantaged because they do not have the power of legal clarity. In addition, unregistered marriages will make it very difficult for the state to supervise the population administration system and the protection of the rights of every Indonesian citizen. 7 The consequences of this behavior do not only have an impact on the individual, the family, but also have an impact on the system as a whole. Legal uncertainty resulting from the unregistered marriage will cause problems in the settlement of cases in religious courts and district courts. 8 In addition, there is a lack of synchronization in population data that will hinder several policy efforts towards comprehensive family protection. This study on marriage registration is very important to be carried out in ensuring that existing legal regulations can be practiced effectively for the sake of legal certainty for Indonesian citizens. Various previous studies have discussed the issue of marriage registration. Sri Hartini et al. 9 researching legal counseling related to the non-registration of marriages in North Bogor District based on the Regulation of the Minister of Religion No. 19 of This study found that legal marriage according to Article 14 of the Compilation of Islamic Law (KHI) 1991 for Muslims includes prospective husband and wife, guardians, witnesses, ijab kabul, and registration at the KUA, while for non-Muslims it is carried out at the Civil Registration Office in accordance with Law No. 1 of 1974. Not recording marriages raises various legal problems, such as difficulties in divorce, birth certificate management, pensions, and inheritance.

Furthermore, the research of Muhammad Sultan Akbar et 12 . concluded that the registration of marriage in Islamic family law, as stipulated in Law No. 1 of 1974, is the obligation of every citizen. The application of Malahah Mursalah in this recording serves to prevent marriage and inheritance disputes and avoid the practice of unofficial marriage, thus maintaining the benefit of the community. Then the research of Khusnul Khotimah and Dani Amran Hakim 13 . shows that the registration of marriages, as well as the relevance of the Qur'an surah Al-Baqarah verse 282, is important as a pillar of administrative legal certainty. At KUA Seputih Agung, recording is carried out in accordance with Article 4 of PMA No. 20/2019 by applying the principle of objectivity in the implementation of duties. Although it contributed to the understanding of marriage registration, various previous researchers still had limitations. Sri Hartini et al. 's research is descriptive, normative, and limited to regional aspects without in-depth social analysis. Alifah and Puti Sabrina's studies focus too much on formal juridical aspects without considering social impacts. Dadan Herdiana and Dian Ekawati are less critical of the Supreme Court's Circular Letter from the perspective of human rights and legal pluralism. Meanwhile, the research of Muhammad Sultan Akbar et al. is still conceptual without an implementive application, and the research of Khusnul Khotimah and Dani Amran Hakim overemphasizes administrative success without addressing the challenges of practice in the field. The novelty in this study lies in a comprehensive approach through the study of legal, sociological, and theological literature related to marriage registration in Indonesia. This article not only synthesizes various views critically, but also affirms that marriage registration is a strategic instrument of family law protection in the context of religious and cultural pluralism. In addition, the article emphasizes the importance of legal certainty based on formal legality, social legitimacy, and substantive justice. This research aims to analyze the importance of marriage registration in the Indonesian legal system, both from the perspective of positive law and Islamic law, as well as to increase public awareness of the legal consequences due to irregularities.

This research also highlights the urgency of marriage registration as a legal instrument that is more than just an administrative obligation, but also as a pillar in guaranteeing civil rights, social protection, and legal order. With an adaptive approach to social norms and simplification of administrative processes, this research aims to strengthen the principle of the state of law based on Pancasila and the 1945 Constitution of the Republic of Indonesia. Research Methods This research uses the Library Research method using a qualitative approach. This method is carried out by examining various data sources related to the Urgency of Marriage Registration in Ensuring Legal Certainty: A Study of Indonesian Family Law Literature. This research does not involve the collection of field data, but focuses on the review of existing legal documents and theories. The goal is to explore a deep understanding of the role of marriage registration in creating legal certainty, as well as identify gaps or legal problems that may arise due to non-registration. This approach also allows the author to analyze legal developments as well as the views of experts in forming a strong argument basis regarding the importance of marriage The data sources used in this study are primary and secondary data sources. Primary data sources include laws and regulations such as Law Number 1 of 1974 concerning Marriage. Government Regulation Number 9 of 1975, and the Compilation of Islamic Law (KHI) which is the basis for analysis of marriage registration arrangements in ensuring legal certainty and protection of civil rights. Meanwhile, secondary data sources are obtained from academic literature such as books, scientific journals, research articles, and legal expert opinions, which enrich the study with theoretical and practical perspectives on the challenges and implementation of marriage registration.

Research Flow The Urgency and Juridical Basis of Marriage Registration in Indonesia Marriage registration is a fundamental aspect of Indonesia's national legal system which aims to provide legal certainty, protection of rights, and maintain social order in society. 14 The recording obtained a solid juridical foundation, which is not only derived from the principles of modern state administration, but also in line with the social need to regulate family relations in a legal and orderly manner. The provisions regarding the obligation to register marriages are explicitly regulated in Law Number 1 of 1974 concerning Marriage. Article 2 paragraph . of the law emphasizes that each marriage is recorded in accordance with the applicable laws and regulations. This provision provides legal reinforcement for every form of marriage, so that it is not only valid according to the religion or beliefs of each party, but also valid according to state law. Registration is not only considered an administrative requirement, but also a legal mechanism that is the basis for obtaining legal recognition of the relationship between husband and wife and the resulting offspring. Regulations regarding marriage registration procedures can be found in Government Regulation Number 9 of 1975 concerning the Implementation of Law Paisal Ahmad Dalimunthe.

Number 1 of 1974 concerning Marriage. 16 This regulation provides procedural details on how registration is carried out, both by the Civil Registration Office for non-Muslims and by the Religious Affairs Office (KUA) for Muslims. Therefore, marriage registration is carried out in accordance with the religious background of each couple, without ruling out the principle of equality before the law. In the context of Muslims in Indonesia, the existence of Presidential Instruction Number 1 of 1991 concerning the Compilation of Islamic Law (KHI) further clarifies the importance of marriage 17 KHI emphasized that every Muslim marriage must be registered with the KUA to obtain legal force. This provision places recording not only as an administrative action, but as an integral part of the implementation of Islamic law in Indonesia which is oriented towards the benefit of the ummah. The following is the function of marriage registration along with an explanation that can be seen in the table below. Table 1.

Marriage registration from the perspective of Islamic law has value in maintaining clarity of the nasab . , regulating the distribution of inheritance, and ensuring justice in social relations. 19 With official registration, the married couple and their descendants get legal recognition that will be able to protect them from possible adverse legal disputes. However, in practice, it is undeniable that some people still consider marriage registration as just an administrative obligation. Negligence in recording can lead to serious legal consequences, including unclear status of children, obstacles in the management of inheritance rights, and vulnerability to violations of the rights of women and children in the household. In an effort to increase public awareness about the importance of marriage registration, continuous education and socialization efforts are needed. This recording is an essential instrument in creating social order, legal certainty, and the protection of civil rights in Indonesian society. The relevant legal provisions are not only intended to fulfill the aspects of administrative formalities, but rather aim to build a just, orderly, and sustainable social structure. 21 By understanding and implementing the obligation to register marriages, the community plays an active role in strengthening the principle of the state of law based on Pancasila and the 1945 Constitution of the Republic of Indonesia. Marriage Registration as an Instrument of Legal Certainty Marriage registration is a form of state recognition of the legal relationship between a man and a woman who are bound in a marriage bond. 22 This recording practice is not merely an administrative action, but a legal process that contains important meaning in order to realize legal certainty, protection of rights, and social Marriage registration provides formal legitimacy to the status of husband and wife before state law, so that all legal consequences attached to the relationship can be carried out effectively and fairly.

The right to inheritance, child custody, the right to alimony, and the right to share common property are concrete examples of the legal consequences arising from a legal and recorded marital relationship. Without registration, the legal position of one party, especially women and children, can be marginalized, potentially causing injustice and human rights violations. Second, marriage registration functions as a preventive effort against future legal disputes. Unclear marital status is often a source of prolonged conflict, especially in cases of divorce, custody of children, and the division of common property. With proof of registration, the state can provide legal protection for the parties, as well as ensure dispute resolution based on the applicable legal provisions. 24 This is in line with the principle of substantive justice which requires equal treatment and protection for those who are more socially vulnerable. Marriage Registration in the Development and Protection of Rights In the social and administrative perspective of the state, marriage registration contributes greatly to the development of accurate population data. The data is the basis for the formulation of various public policies, especially those related to family development, maternal and child health, education, and social 25 Without good records, the state will experience difficulties in planning and supervising various family welfare programs, which can ultimately hinder the achievement of national development goals. From a human rights perspective, marriage registration is also a form of respect for the right of every individual to be recognized before the law. 26 This is especially important in the context of the protection of women and children, a group that is often victimized in situations of unclear marital status. Official registration guarantees that their rights, both in family relationships and in community life, receive proper legal protection. By paying attention to these various dimensions, marriage registration cannot actually be seen as just an administrative obligation, but as a fundamental pillar in building a fair, orderly, and civilized family law order. 27 Therefore, systematic efforts are needed to increase public legal awareness of the importance of marriage registration, both in the form of socialization and improvements in regulations that facilitate the registration process without reducing the legality and Rudy Catur Rohman Kusmayadi dan Muhammad Madarik.

The state is present through its legal system, has the responsibility to ensure that every marriage is officially registered, thus providing legal certainty to all parties involved and strengthening the foundation of justice in society. Critical Analysis of Marriage Registration Practices in the Community Although the obligation to register marriage has been regulated in Law Number 1 of 1974 and its derivative regulations, the practice of marriage without official registration is still widely found. The rarity between positive legal norms and public awareness is one of the main causes, where many couples only rely on traditional or religious ceremonies without state registration. As a result, legal protection of the rights of spouses and children becomes weak, and hinders the accuracy of national population data. Therefore, efforts to socialize the law, empower the community, and simplify administration are needed to encourage awareness of the importance of marriage registration in realizing legal order and protection of official human rights.

As a result, many view recording as a mere formal procedure without realizing the legal protection that is lost if the recording is ignored. The impact of not registering marriage is very broad and serious. In many cases, especially in rural areas, married couples who are married only customarily face difficulties when it comes to taking care of birth certificates, applying for inheritance, or suing for divorce in court. 30 The lack of marriage records causes their legal status to be weakened, thus hindering efforts to obtain recognition of civil rights. This phenomenon emphasizes the importance of more strategic efforts by the government, religious institutions, and community organizations in increasing awareness of the importance of marriage registration. The educational approach carried out should pay attention to local values so that they are more easily accepted by the community. addition, the provision of incentives in the form of waivers for marriage registration fees for weak economic groups can be a concrete step to overcome financial barriers. In the process of developing the national legal system, the existence of marriage registration can no longer be understood simply as a procedural administrative obligation. 31 Marriage registration has a function in ensuring legal certainty for individuals, strengthening the protection of civil rights, and being the foundation in realizing the principle of justice for all citizens. With written evidence in the form of a marriage certificate issued by the state, each individual obtains official recognition of his or her marital legal status, which further has an impact on the clarity of legal relations, both in the fields of family, inheritance, and the right to social 32 Marriage registration plays an active role as a state instrument in protecting the human rights of its citizens and creating an orderly social order. In the face of the very diverse social dynamics of Indonesian society, marriage registration must be placed as a strategic instrument in strengthening a fair and inclusive national legal system. The presence of registration is not only to meet formal legal requirements, but also to become a symbol of the state in recognizing and protecting the civil rights of its people. The importance of this recording is increasingly felt in the context of the complexity of modern society, where social mobility is high and the need for legal protection is increasing. 33 The state must ensure that all levels of society understand the importance of marriage registration through a persuasive, educational, and adaptive approach to the evolving social realities, in order to create synergy Tin Widayati.

Flow Diagram Critical analysis of problems, theories, strategies and research outputs of marriage registration practices in the Based on the diagram above, it can be seen that marriage registration does not only function as an administrative obligation, but is an instrument in ensuring legal certainty, protection of civil rights, and social order in the life of society and the state. Through an understanding of the theory of legal certainty and the theory of social change, appropriate strategies can be prepared, such as legal education, community empowerment, simplification of administration, and the provision of economic incentives to increase awareness of the importance of marriage registration. It is hoped that the synergy between the country's legal norms and the social reality of society can be realized, so that every individual obtains fair, equitable, and sustainable legal protection in a dynamic and inclusive national legal system. Legal Implications of Not Registering Marriage In the Indonesian legal system, marriage registration plays a central role in ensuring clarity of an individual's legal status. If a marriage is not officially registered, there will be serious legal consequences. One of the main impacts is the unclear legal ANALYSIS OF LEGAL CERTAINTY IN INDONESIA. Ahmad Fauzi, et. status between husbands, wives, and children born of such marriages in the eyes of the state. 34 Children born to marriages that are not officially registered have the potential to gain out-of-wedlock child status, which can ultimately affect their various civil rights, including inheritance rights, maintenance rights, and legal identity rights. This of course puts the child in a situation that is vulnerable to legal injustice, which is contrary to the principle of protection of children's rights as regulated in national and international law. The Impact of Marriage Registration on Divorce The absence of marriage registration poses serious challenges in the divorce process. One of the important aspects of divorce is proving the existence of a legal relationship between husband and wife. Without formal evidence such as a marriage certificate, the evidentiary process becomes vulnerable to prolonged Thus, the parties to the conflict, especially women, face difficulties in obtaining the legal protection they should receive. This condition shows that marriage registration is not just an administrative formality, but an important foundation for resolving legal problems in the family. Legal Implications for Child Custody and Joint Property The absence of a marriage certificate also has a direct impact on the determination of child custody and the distribution of joint property. In Indonesian law, the existence of official documents is the main evidence to claim civil rights over children and assets acquired during marriage. When no recording is done, the legal status of the child becomes blurred, and the joint property is difficult to identify and divide fairly. This situation exacerbates legal uncertainty, opens up space for injustice, and has the potential to weaken legal protections for the more vulnerable parties in the household. Legal Uncertainty and Social Inequality The inability to prove the existence of marriage legally in the eyes of the law also increases the risk of social inequality. Women and children, as the most frequently affected parties, face the possibility of losing their livelihoods, housing rights, and inheritance rights. This legal uncertainty not only impacts individuals, but also impacts broader social structures, creating instability in society. Official marriage registration is an instrument to prevent systemic injustice and to strengthen the guarantee of protection of basic rights in a just society. Given the magnitude of the impact of unregistered marriages, national law provides a corrective mechanism in the form of isbat nikah. However, in addition to that, it can also be through "Recognition" regulated in the Population Administration and Civil Registration Law through an application to the court. Although it aims to provide solutions, the isbat process is often constrained by lengthy procedures, high costs, and proof, thus burdening the community. Roy Suwarno Putro dkk.
