Can I get guardianship of my 13 year old brother?

Me. Louden's statement herein is correct. See an attorney.

We have guar of our nephew, and now mom what's him back. What do we do?

If you have a legal guardianship, wait until she filed a Motion to Terminate it amd then get an attorney.

Can you change your mind?

Have him ask his attorney. You have 10 days to withdraw your plea and it is very hard to withdraw a plea.

Do I have the legal rights to go get my daughter from them?

Find an attorney who practices in tribal court.

Paternity does not give you custody rights. You must file an action in court.

Did the courts and Cps screw me over

Follow Mr. Loudens advice herein. A lot is going on here.

Yes you have good reasons to modify. The remarriage is basically irrelevant.

Can my husband adopt my son if his biological dad is not involved?

I do believe the biological father is entitled to notice.

Me and my wife are on everything we want to do as far as the divorce goes but what do we do as far as my 401 k?

The 401k generally had to be divided by a Qualified Domestic Relations Order. See an attorney.

Yes he should disclose it. He is probably hiding something.
