A refusal to furnish support to one whom the party thus refusing is legally bound to support, may amount to duress.1 The threat of a husband to refuse to support his wife may amount to duress.2 A threat of a husband to abandon his wife may amount to duress.3 If the person who refuses to furnish support is not bound to furnish such support, his refusal is not duress.4 The son's fear that his father will be angry and will refuse to support him, is not duress.5 The refusal of a son to support his father is not duress.6 The statement by a husband to his wife that he is involved in business because of her refusal to secure a divorce from him, and that he will be obliged to leave the state if she persists in such refusal, does not amount to duress.7
