Can I file an adultery charge to contest a divorce and send a subpoena to the third party?

You file. Yes. Unless she lies like a dog.

See an attorney and file, at least in Michigan there is no need fro such grounds or information.

In California adultery is not grounds for divorce. You just need irreconcilable differences and either part can file. If you're not in California find a local attorney.

California is a no-fault state, if you are in California, you simply file that there are irreconcilable differences (without naming what those differences are). If you are in a state that requires one of you to blame the other and state a reason, why don't you file the case and state that she is committing adultery and request divorce?

In Kansas, adultery is no longer a specifically recognized ground for divorce. The official grounds for divorce are as follows: 23-2701. Grounds for divorce or separate maintenance. (a) The district court shall grant a decree of divorce or separate maintenance for any of the following grounds: (1) Incompatibility; (2) failure to perform a material marital duty or obligation; or (3) incompatibility by reason of mental illness or mental incapacity of one or both spouses.

You can file for a divorce. Adultery is not a ground for divorce in California. We are a no fault state so the only real ground you can state on the paper work is adultery. People's sex lives are not relevant to divorce cases so you would probably not be allowed to force your wife to give up the boy friend's name.

File the case yourself as the petitioner.

Sorry, dissolution in California is no fault and the actions of your spouse are irrelevant to any dissolution proceedings.

California is a no fault divorce state, so you don't file on grounds of adultery.

Michigan is a no-fault divorce state so you could file on your own simply by alleging that there has been a breakdown of the marital relationship to the extent the objects of matrimony have been destroyed and there is no likelihood of reconsiliation. If you are in a state where fault must be alleged, you could still file alleging her actions as the required fault.
