What do I do?

Hire an attorney, pronto. With that kind of money at stake, time is absolutely of the essence.

Legal grounds to contest a will

On that alone, no. The issue is usually more about the circumstances of the making of the will.

Is there a law in Iowa against broadcasting a 15 year old son's photo without parental consent?

It depends on several things, and there's not a hard, fast rule. You'd need to talk to an attorney to see if his privacy has been violated.

I have recently received a request for an audit through an insurance company. I’m a provider.

It may be worth contesting, maybe not. Hard to know without context. You'd want an attorney with insurance company experience. I don't know...

Can I leagally break a lease due to cockroach problems without financial obligations?

Maybe, maybe not. The LL has a responsibility to take care of pests, but your conduct must be reasonable, too, and the cleanliness of your unit...

Can i sue dollar General?

Some bureaucratic delay is certainly not worth suing someone over.

They claimed that I stole $20 from the self-checkout. They said they have me on video.

Maybe yes, maybe no. It's a bit more complicated than just whether you got sick or not.

How do i obtain temporary guardianship of my grandsons who live with me??

Usually the person who wants the guardianship initiates it. You'll have the best luck if you initiate it if the mother has the state involved.

Probably yes, but it's not a fully developed area of the law in Iowa as far as I know.
