My wife left and is filing for divorce. Her demands for a clean divorce involve splitting 2 years worth of tax returns that I earned as sole breadwinner. Some havent been cashed yet. This is difficult considering she isn't here to sign them. What is the best way to go about this to make sure it is legally air tight. I didn't want to just hand money over to her. Events and transactions need to be proven and notorized. Whats the best way to go about this? I thought about getting a lawyer, but I dont know if spending the money is necessary. Is there a way I could write up a contract that we agree on.
