Colorado’s act does not automatically void a prenup if someone lacked a lawyer, but access to independent legal counsel is a key enforceability factor. A prenup can be ruled unenforceable if a party proves they did not have access to independent counsel. It can also be unenforceable if, without counsel, the agreement lacked a conspicuous waiver notice or plain-language explanation of rights being changed. Before signing, each party must receive adequate financial disclosure. The agreement must also be voluntary and free from duress. These rules appear in Colorado’s Uniform Premarital and Marital Agreements Act.
