Step-by-step explanation:
Reciprocal beneficiaries are individuals who are registered under a legal framework that provides them with certain rights and benefits, similar to those enjoyed by married couples. In some jurisdictions, unrelated individuals or same-sex couples may register as reciprocal beneficiaries. However, the requirements and eligibility criteria vary depending on the specific laws of each jurisdiction.
For example, in Hawaii, reciprocal beneficiaries include unrelated individuals who are at least 18 years old and not nearer in blood relation than first cousins. Siblings are generally not eligible to register as reciprocal beneficiaries, as they are already recognized as part of the same family unit. Married couples and grandparents may also register as reciprocal beneficiaries in certain jurisdictions.
