Which law relates to personal matters such as marriage and divorce?

The law that specifically relates to personal matters such as marriage and divorce is civil law. Civil law governs private rights and obligations and deals with issues that are non-criminal in nature. This branch of law primarily focuses on disputes between individuals or entities over rights that can include marriage, divorce, contracts, property, and family matters.

In the context of marriage and divorce, civil law provides the framework for how these personal relationships are legally recognized, how disputes are settled, and how rights and obligations are enforced. For example, civil law outlines the requirements for legally marrying, the process for filing for divorce, and the distribution of assets following a divorce.

State law also plays a significant role in these personal matters, as marriage and divorce laws can vary from one state to another. However, civil law is the broader category under which personal matters like marriage and divorce fall. Thus, civil law is the correct answer when discussing the legal framework governing these personal issues.
