It is not "illegal" but Nevada has jurisdiction over the child and he could file a divorce case here with an emergency motion to have the child returned to Nevada to his custody. That leaves you fighting a custody battle long distance while he has custody. Further, under Nevada law, if you move a child out of state without your husband's written permission, that can be used against you in any subsequent custody proceeding. So unless he will give you written consent to move the child to California, you are taking a huge risk in moving. Your only other option is to get your divorce case underway in Nevada, and get the court's permission to move the child to California. Either way, you should be consulting with and retaining an attorney.

Ms. Whitbeck is correct. You really should try to get his consent in writing (or at least an email) before you move, and you will likely be fighting this in Nevada unless you are in California for at least six months before anybody files. California would obtain jurisdiction if the 15 year old is in the state for six months. So if your husband can be appeased for six months, that might work as well. But it's a huge risk. Consult with a family law attorney before you do anything.
