Under Guam law, which of the following actions requires a court order?

Establishing paternity under Guam law requires a court order because it involves legal recognition of a father-child relationship, which has significant implications for child support, custody, and inheritance rights. The court must determine paternity through legal proceedings, especially in cases where the father's identity is disputed or if the parents were not married at the time of the child's birth. This judicial process ensures that all legal standards are met and provides a formal acknowledgment of paternity that is enforceable in law.

In contrast, creating a will, filing for divorce, and applying for a business license do not inherently require a court order, as they are generally pursued through administrative actions or personal decisions without needing direct judicial intervention. Creating a will is a private matter of estate planning, while divorce proceedings may begin without a court order, though they eventually necessitate court involvement to finalize the dissolution of marriage. Applying for a business license involves compliance with local regulations and obtaining the necessary approvals, which is managed through administrative channels rather than the court system.
