If you’re having an affair, something that you may want to consider is whether the person you are having an affair with can claim your property after the relationship breaks down.
Firstly, your family law lawyers will need to consider whether your affair amounts to a de facto relationship. Considerations include the duration of the relationship, whether you have lived together, whether you attend events together socially, and whether you depend on each other financially.
The case of Jonah v White (2011) considered whether someone you are having an affair with can amount to a de facto relationship. In this case, the Husband (H) had a 17 year long affair with a woman (Ms J). During the affair, H continued to live with his wife and three children. Family law lawyers for Ms J argued that the relationship she had with H amounted to a de facto relationship under the Family Law Act.
The Court said that “The key to the definition is the manifestation of a relationship where the parties have so merged their lives that they are, for all practical purposes, living together as a couple on a genuine domestic basis. It is the manifestation of “coupledom”, which involves the merger of two lives as just described, that is the core of a de facto relationship as defined [by the law]”.
