In New Hampshire, common law marriage does not exist. However, there are certain circumstances in which individuals who have been living together as spouses without being legally married may need to establish their relationship for various legal purposes. In such cases, New Hampshire provides the option of utilizing a Marriage Declaration or Affidavit. A Marriage Declaration or Affidavit in New Hampshire is a legal document used to affirm the existence of a committed domestic relationship between two individuals who have been living together without being formally married. This document helps establish the legal status of the relationship and allows couples to avail certain benefits and rights that are typically associated with traditionally married couples. It's crucial to note that while this affidavit does not create a common law marriage, it serves as evidence of a committed relationship when dealing with matters such as property rights, healthcare decisions, insurance benefits, or parental rights. Different types of Marriage Declaration or Affidavit in New Hampshire may include: 1. New Hampshire Marriage Declaration: The New Hampshire Marriage Declaration is a written statement signed by both partners, declaring their intent to form a life partnership and affirming that they have been living together as spouses. This document generally outlines the duration of the relationship and includes personal details of both parties. 2. New Hampshire Common Law Spouse Affidavit: The New Hampshire Common Law Spouse Affidavit is a legally binding document that requires both partners to provide sworn testimony, attesting that they have lived together as spouses, maintain a mutually supportive relationship, and present themselves to others as a married couple. 3. New Hampshire Domestic Partnership Affidavit: While not specific to common law spouses, the New Hampshire Domestic Partnership Affidavit is an alternative legal option available to couples who are in long-term committed relationships, regardless of their marital status or gender. This affidavit establishes a legal partnership with rights and responsibilities similar to those of married couples. It's important to consult an attorney or legal professional to ensure that the chosen declaration or affidavit meets the specific requirements and serves the intended purpose. The exact content and format may vary depending on the purpose, jurisdiction, and specific circumstances involved.
