The term 'acrimony' describes a state of anger and bitterness, particularly in relationships or during disputes. It often characterizes a hostile environment where emotions run high, leading to conflict and a lack of harmony between parties. This term is commonly used to describe situations in legal contexts, such as contentious disputes or divorces, where feelings of resentment and hostility can escalate. Understanding this term is crucial for recognizing the emotional tone of cases and how it may affect legal proceedings or negotiations.

The other options describe different legal concepts or actions: a legal retraction of a will refers to a formal process of revoking a will; a process of investigation pertains to systematically examining facts or gathering evidence, and a written statement under oath defines a formal declaration made in a legal context. However, none encapsulate the emotional and interpersonal nuances captured by 'acrimony.'
