Q: Can my husband hire an attorney I have already spoken to about our divorce but did not hire?
No unless you give your permission.
If you speak to a lawyer about your case your husband cannot later hire that lawyer to represent him in your divorce, custody or support matter. The reason being, you have likely communicated confidential information to the lawyer you spoke with. And, that lawyer, even if you have not paid them anything, owes you a duty of confidentiality.
In conclusion, you should know that you can speak honestly and open;y with a lawyer, whether or not you hire that lawyer, about your divorce, custody and/or support matter and not worry about that lawyer using that information against you later.
